User A has chosen to use PKI to secure his message and ensure only user B can read the sensitive email. At what layer of the OSI layer does the encryption and decryption of the message take place? A. Application B. Transport C. Session D. Presentation Answer: D Explanation https://en.wikipedia.org/wiki/Presentation_layer In the seven-layer OSI model of computer networking, the presentation layer is layer 6 and serves as the data translator for the network. It is sometimes called the syntax layer. The presentation layer is responsible for the formatting and delivery of information to the application layer for further processing or display. Encryption is typically done at this level too, although it can be done on the application, session, transport, or network layers, each having its own advantages and disadvantages. Decryption is also handled at the presentation layer. For example, when logging on to bank account sites the presentation layer will decrypt the data as it is received. Question #:2 - (Exam Topic 1) If a tester is attempting to ping a target that exists but receives no response or a response that states the destination is unreachable, ICMP may be disabled and the network may be using TCP. Which other option could the tester use to get a response from a host using TCP? A. Traceroute B. Hping C. TCP ping D. Broadcast ping Answer: B Explanation 100% Success with DumpsPedia.com 2 of 368 Braindumps Questions ECCouncil - 312-50v12 https://tools.kali.org/information-gathering/hping3 http://www.carnal0wnage.com/papers/LSO-Hping2-Basics.pdf Question #:3 - (Exam Topic 1) CompanyXYZ has asked you to assess the security of their perimeter email gateway. From your office in New York, you craft a specially formatted email message and send it across the Internet to an employee of CompanyXYZ. The employee of CompanyXYZ is aware of your test. Your email message looks like this: From: [email protected] To: [email protected] Subject: Test message Date: 4/3/2017 14:37 The employee of CompanyXYZ receives your email message. This proves that CompanyXYZ’s email gateway doesn’t prevent what? A. Email Masquerading B. Email Harvesting C. Email Phishing D. Email Spoofing Answer: D Explanation Email spoofing is the fabrication of an email header in the hopes of duping the recipient into thinking the email originated from someone or somewhere other than the intended source. Because core email protocols do not have a built-in method of authentication, it is common for spam and phishing emails to use said spoofing to trick the recipient into trusting the origin of the message. The ultimate goal of email spoofing is to get recipients to open, and possibly even respond to, a solicitation. Although the spoofed messages are usually just a nuisance requiring little action besides removal, the more malicious varieties can cause significant problems and sometimes pose a real security threat. Question #:4 - (Exam Topic 1) When you are getting information about a web server, it is very important to know the HTTP Methods (GET, POST, HEAD, PUT, DELETE, TRACE) that are available because there are two critical methods (PUT and DELETE). PUT can upload a file to the server and DELETE can delete a file from the server. You can detect all these methods (GET, POST, HEAD, DELETE, PUT, TRACE) using NMAP script engine. What Nmap script will help you with this task? A. 100% Success with DumpsPedia.com 3 of 368 Braindumps Questions ECCouncil - 312-50v12 A. http-methods B. http enum C. http-headers D. http-git Answer: A Question #:5 - (Exam Topic 1) Suppose your company has just passed a security risk assessment exercise. The results display that the risk of the breach in the main company application is 50%. Security staff has taken some measures and implemented the necessary controls. After that, another security risk assessment was performed showing that risk has decreased to 10%. The risk threshold for the application is 20%. Which of the following risk decisions will be the best for the project in terms of its successful continuation with the most business profit? A. Accept the risk B. Introduce more controls to bring risk to 0% C. Mitigate the risk D. Avoid the risk Answer: A Explanation Risk Mitigation Risk mitigation can be defined as taking steps to reduce adverse effects. There are four types of risk mitigation strategies that hold unique to Business Continuity and Disaster Recovery. When mitigating risk, it’s important to develop a strategy that closely relates to and matches your company’s profile. A picture containing diagram Description automatically generated 100% Success with DumpsPedia.com 4 of 368 Braindumps Questions ECCouncil - 312-50v12 Risk Acceptance Risk acceptance does not reduce any effects; however, it is still considered a strategy. This strategy is a common option when the cost of other risk management options such as avoidance or limitation may outweigh the cost of the risk itself. A company that doesn’t want to spend a lot of money on avoiding risks that do not have a high possibility of occurring will use the risk acceptance strategy. Risk Avoidance Risk avoidance is the opposite of risk acceptance. It is the action that avoids any exposure to the risk whatsoever. It’s important to note that risk avoidance is usually the most expensive of all risk mitigation options. 100% Success with DumpsPedia.com 5 of 368 Braindumps Questions ECCouncil - 312-50v12 Risk Limitation Risk limitation is the most common risk management strategy used by businesses. This strategy limits a company’s exposure by taking some action. It is a strategy employing a bit of risk acceptance and a bit of risk avoidance or an average of both. An example of risk limitation would be a company accepting that a disk drive may fail and avoiding a long period of failure by having backups. Risk Transference Risk transference is the involvement of handing risk off to a willing third party. For example, numerous companies outsource certain operations such as customer service, payroll services, etc. This can be beneficial for a company if a transferred risk is not a core competency of that company. It can also be used so a company can focus more on its core competencies. Question #:6 - (Exam Topic 1) One of your team members has asked you to analyze the following SOA record. What is the TTL? Rutgers.edu.SOA NS1.Rutgers.edu ipad.college.edu (200302028 3600 3600 604800 2400.) A. 200303028 B. 3600 C. 604800 D. 2400 E. 60 F. 4800 Answer: D Question #:7 - (Exam Topic 1) Under what conditions does a secondary name server request a zone transfer from a primary name server? A. When a primary SOA is higher that a secondary SOA B. When a secondary SOA is higher that a primary SOA C. When a primary name server has had its service restarted D. When a secondary name server has had its service restarted E. When the TTL falls to zero 100% Success with DumpsPedia.com 6 of 368 Braindumps Questions ECCouncil - 312-50v12 Answer: A Question #:8 - (Exam Topic 1) Which of the following programs is usually targeted at Microsoft Office products? A. Polymorphic virus B. Multipart virus C. Macro virus D. Stealth virus Answer: C Explanation A macro virus is a virus that is written in a macro language: a programming language which is embedded inside a software application (e.g., word processors and spreadsheet applications). Some applications, such as Microsoft Office, allow macro programs to be embedded in documents such that the macros are run automatically when the document is opened, and this provides a distinct mechanism by which malicious computer instructions can spread. (Wikipedia) NB: The virus Melissa is a well-known macro virus we could find attached to word documents. Question #:9 - (Exam Topic 1) Which of the following is a component of a risk assessment? A. Administrative safeguards B. Physical security C. DMZ D. Logical interface Answer: A Question #:10 - (Exam Topic 1) Session splicing is an IDS evasion technique in which an attacker delivers data in multiple, small sized packets to the target computer, making it very difficult for an IDS to detect the attack signatures. Which tool can be used to perform session splicing attacks? A. 100% Success with DumpsPedia.com 7 of 368 Braindumps Questions ECCouncil - 312-50v12 A. tcpsplice B. Burp C. Hydra D. Whisker Answer: D Explanation «Many IDS reassemble communication streams; hence, if a packet is not received within a reasonable period, many IDS stop reassembling and handling that stream. If the application under attack keeps a session active for a longer time than that spent by the IDS on reassembling it, the IDS will stop. As a result, any session after the IDS stops reassembling the sessions will be susceptible to malicious data theft by attackers. The IDS will not log any attack attempt after a successful splicing attack. Attackers can use tools such as Nessus for session splicing attacks.» Did you know that the EC-Council exam shows how well you know their official book? So, there is no "Whisker" in it. In the chapter "Evading IDS" -> "Session Splicing", the recommended tool for performing a session-splicing attack is Nessus. Where Wisker came from is not entirely clear, but I will assume the author of the question found it while copying Wikipedia. https://en.wikipedia.org/wiki/Intrusion_detection_system_evasion_techniques One basic technique is to split the attack payload into multiple small packets so that the IDS must reassemble the packet stream to detect the attack. A simple way of splitting packets is by fragmenting them, but an adversary can also simply craft packets with small payloads. The 'whisker' evasion tool calls crafting packets with small payloads 'session splicing'. By itself, small packets will not evade any IDS that reassembles packet streams. However, small packets can be further modified in order to complicate reassembly and detection. One evasion technique is to pause between sending parts of the attack, hoping that the IDS will time out before the target computer does. A second evasion technique is to send the packets out of order, confusing simple packet re-assemblers but not the target computer. NOTE: Yes, I found scraps of information about the tool that existed in 2012, but I can not give you unverified information. According to the official tutorials, the correct answer is Nessus, but if you know anything about Wisker, please write in the QA section. Maybe this question will be updated soon, but I'm not sure about that. Question #:11 - (Exam Topic 1) Which of the following tools can be used to perform a zone transfer? A. NSLookup B. Finger C. 100% Success with DumpsPedia.com 8 of 368 Braindumps Questions ECCouncil - 312-50v12 C. Dig D. Sam Spade E. Host F. Netcat G. Neotrace Answer: A C D E Question #:12 - (Exam Topic 1) Scenario1: 1.Victim opens the attacker's web site. 2.Attacker sets up a web site which contains interesting and attractive content like 'Do you want to make $1000 in a day?'. 3.Victim clicks to the interesting and attractive content URL. 4.Attacker creates a transparent 'iframe' in front of the URL which victim attempts to click, so victim thinks that he/she clicks to the 'Do you want to make $1000 in a day?' URL but actually he/she clicks to the content or URL that exists in the transparent 'iframe' which is setup by the attacker. What is the name of the attack which is mentioned in the scenario? A. Session Fixation B. HTML Injection C. HTTP Parameter Pollution D. Clickjacking Attack Answer: D Explanation https://en.wikipedia.org/wiki/Clickjacking Clickjacking is an attack that tricks a user into clicking a webpage element which is invisible or disguised as another element. This can cause users to unwittingly download malware, visit malicious web pages, provide credentials or sensitive information, transfer money, or purchase products online. Typically, clickjacking is performed by displaying an invisible page or HTML element, inside an iframe, on 100% Success with DumpsPedia.com 9 of 368 Braindumps Questions ECCouncil - 312-50v12 top of the page the user sees. The user believes they are clicking the visible page but in fact they are clicking an invisible element in the additional page transposed on top of it. Question #:13 - (Exam Topic 1) Which regulation defines security and privacy controls for Federal information systems and organizations? A. HIPAA B. EU Safe Harbor C. PCI-DSS D. NIST-800-53 Answer: D Explanation NIST Special Publication 800-53 provides a catalog of security and privacy controls for all U.S. federal information systems except those related to national security. It is published by the National Institute of Standards and Technology, which is a non-regulatory agency of the United States Department of Commerce. NIST develops and issues standards, guidelines, and other publications to assist federal agencies in implementing the Federal Information Security Modernization Act of 2014 (FISMA) and to help with managing cost-effective programs to protect their information and information systems. Question #:14 - (Exam Topic 1) The configuration allows a wired or wireless network interface controller to pass all traffic it receives to the Central Processing Unit (CPU), rather than passing only the frames that the controller is intended to receive.

Hash Algorithm Answer: C Question #:16 - (Exam Topic 1) A company’s policy requires employees to perform file transfers using protocols which encrypt traffic. You suspect some employees are still performing file transfers using unencrypted protocols because the employees do not like changes. You have positioned a network sniffer to capture traffic from the laptops used by employees in the data ingest department. Using Wireshark to examine the captured traffic, which command can be used as display filter to find unencrypted file transfers? A. tcp.port = = 21 B. tcp.port = 23 C. tcp.port = = 21 | | tcp.port = =22 D. tcp.port ! = 21 Answer: A Question #:17 - (Exam Topic 1) What kind of detection techniques is being used in antivirus software that identifies malware by collecting data from multiple protected systems and instead of analyzing files locally it’s made on the provider’s environment? A. Behavioral based B. Heuristics based C. Honeypot based D. Cloud based Answer: D Question #:18 - (Exam Topic 1) 100% Success with DumpsPedia.com 11 of 368 Braindumps Questions ECCouncil - 312-50v12 What is the purpose of a demilitarized zone on a network? A. To scan all traffic coming through the DMZ to the internal network B. To only provide direct access to the nodes within the DMZ and protect the network behind it C. To provide a place to put the honeypot D. To contain the network devices you wish to protect Answer: B Question #:19 - (Exam Topic 1) What is the proper response for a NULL scan if the port is closed? A. SYN B. ACK C. FIN D. PSH E. RST F. No response Answer: E Question #:20 - (Exam Topic 1) You have successfully comprised a server having an IP address of 10.10.0.5. You would like to enumerate all machines in the same network quickly. What is the best Nmap command you will use? A. nmap -T4 -q 10.10.0.0/24 B. nmap -T4 -F 10.10.0.0/24 C. nmap -T4 -r 10.10.1.0/24 D. nmap -T4 -O 10.10.0.0/24 Answer: B 100% Success with DumpsPedia.com 12 of 368 Braindumps Questions ECCouncil - 312-50v12 Explanation https://nmap.org/book/man-port-specification.html NOTE: In my opinion, this is an absolutely wrong statement of the question. But you may come across a question with a similar wording on the exam. What does "fast" mean? If we want to increase the speed and intensity of the scan we can select the mode using the -T flag (0/1/2/3/4/5). At high -T values, we will sacrifice stealth and gain speed, but we will not limit functionality. «nmap -T4 -F 10.10.0.0/24» This option is "correct" because of the -F flag. -F (Fast (limited port) scan) Specifies that you wish to scan fewer ports than the default. Normally Nmap scans the most common 1,000 ports for each scanned protocol. With -F, this is reduced to 100. Technically, scanning will be faster, but just because we have reduced the number of ports by 10 times, we are just doing 10 times less work, not faster. Question #:21 - (Exam Topic 1) Which of the following statements about a zone transfer is correct? (Choose three.) A. A zone transfer is accomplished with the DNS B. A zone transfer is accomplished with the nslookup service C. A zone transfer passes all zone information that a DNS server maintains D.

Answer: A Question #:25 - (Exam Topic 1) A technician is resolving an issue where a computer is unable to connect to the Internet using a wireless access point. The computer is able to transfer files locally to other machines, but cannot successfully reach the Internet. When the technician examines the IP address and default gateway they are both on the 100% Success with DumpsPedia.com 14 of 368 Braindumps Questions ECCouncil - 312-50v12 192.168.1.0/24. Which of the following has occurred? A. The computer is not using a private IP address. B. The gateway is not routing to a public IP address. C. The gateway and the computer are not on the same network. D. The computer is using an invalid IP address. Answer: B Explanation https://en.wikipedia.org/wiki/Private_network In IP networking, a private network is a computer network that uses private IP address space. Both the IPv4 and the IPv6 specifications define private IP address ranges. These addresses are commonly used for local area networks (LANs) in residential, office, and enterprise environments. Private network addresses are not allocated to any specific organization. Anyone may use these addresses without approval from regional or local Internet registries. Private IP address spaces were originally defined to assist in delaying IPv4 address exhaustion. IP packets originating from or addressed to a private IP address cannot be routed through the public Internet. The Internet Engineering Task Force (IETF) has directed the Internet Assigned Numbers Authority (IANA) to reserve the following IPv4 address ranges for private networks: · 10.0.0.0 – 10.255.255.255 · 172.16.0.0 – 172.31.255.255 · 192.168.0.0 – 192.168.255.255 Backbone routers do not allow packets from or to internal IP addresses. That is, intranet machines, if no measures are taken, are isolated from the Internet. However, several technologies allow such machines to connect to the Internet. · Mediation servers like IRC, Usenet, SMTP and Proxy server · Network address translation (NAT) · Tunneling protocol NOTE: So, the problem is just one of these technologies. Question #:26 - (Exam Topic 1) What term describes the amount of risk that remains after the vulnerabilities are classified and the countermeasures have been deployed? 100% Success with DumpsPedia.com 15 of 368 Braindumps Questions ECCouncil - 312-50v12 A. Residual risk B. Impact risk C. Deferred risk D. Inherent risk Answer: A Explanation https://en.wikipedia.org/wiki/Residual_risk The residual risk is the risk or danger of an action or an event, a method or a (technical) process that, although being abreast with science, still conceives these dangers, even if all theoretically possible safety measures would be applied (scientifically conceivable measures); in other words, the amount of risk left over after natural or inherent risks have been reduced by risk controls. · Residual risk = (Inherent risk) – (impact of risk controls) Question #:27 - (Exam Topic 1) Why would you consider sending an email to an address that you know does not exist within the company you are performing a Penetration Test for? A. To determine who is the holder of the root account B. To perform a DoS C. To create needless SPAM D. To illicit a response back that will reveal information about email servers and how they treat undeliverable mail E. To test for virus protection Answer: D Question #:28 - (Exam Topic 1) Which DNS resource record can indicate how long any "DNS poisoning" could last? A. MX B. SOA C. 100% Success with DumpsPedia.com 16 of 368 Braindumps Questions ECCouncil - 312-50v12 C. NS D. TIMEOUT Answer: B Question #:29 - (Exam Topic 1) Bob is doing a password assessment for one of his clients. Bob suspects that security policies are not in place. He also suspects that weak passwords are probably the norm throughout the company he is evaluating. Bob is familiar with password weaknesses and key loggers. Which of the following options best represents the means that Bob can adopt to retrieve passwords from his clients hosts and servers? A. Hardware, Software, and Sniffing. B. Hardware and Software Keyloggers. C. Passwords are always best obtained using Hardware key loggers. D. Software only, they are the most effective. Answer: A Question #:30 - (Exam Topic 1) Although FTP traffic is not encrypted by default, which layer 3 protocol would allow for end-to-end encryption of the connection? A. SFTP B. Ipsec C. SSL D. FTPS Answer: B Explanation https://en.wikipedia.org/wiki/IPsec Internet Protocol Security (IPsec) is a secure network protocol suite that authenticates and encrypts the packets of data to provide secure encrypted communication between two computers over an Internet Protocol network. It is used in virtual private networks (VPNs). 100% Success with DumpsPedia.com 17 of 368 Braindumps Questions ECCouncil - 312-50v12 IPsec includes protocols for establishing mutual authentication between agents at the beginning of a session and negotiation of cryptographic keys to use during the session. IPsec can protect data flows between a pair of hosts (host-to-host), between a pair of security gateways (network-to-network), or between a security gateway and a host (network-to-host). IPsec uses cryptographic security services to protect communications over Internet Protocol (IP) networks. It supports network-level peer authentication, data-origin authentication, data integrity, data confidentiality (encryption), and replay protection. The initial IPv4 suite was developed with few security provisions. As a part of the IPv4 enhancement, IPsec is a layer 3 OSI model or internet layer end-to-end security scheme. In contrast, while some other Internet security systems in widespread use operate above layer 3, such as Transport Layer Security (TLS) that operates at the Transport Layer and Secure Shell (SSH) that operates at the Application layer, IPsec can automatically secure applications at the IP layer. Question #:31 - (Exam Topic 1) Which Intrusion Detection System is the best applicable for large environments where critical assets on the network need extra scrutiny and is ideal for observing sensitive network segments? A. Honeypots B. Firewalls C. Network-based intrusion detection system (NIDS) D. Host-based intrusion detection system (HIDS) Answer: C Question #:32 - (Exam Topic 1) Which of the following algorithms can be used to guarantee the integrity of messages being sent, in transit, or stored? A. symmetric algorithms B. asymmetric algorithms C. hashing algorithms D. integrity algorithms Answer: C Question #:33 - (Exam Topic 1) 100% Success with DumpsPedia.com 18 of 368 Braindumps Questions ECCouncil - 312-50v12 While using your bank’s online servicing you notice the following string in the URL bar: “http: // www.

Which type of vulnerability is present on this site? A. Cookie Tampering B. SQL Injection C. Web Parameter Tampering D. XSS Reflection Answer: C Question #:34 - (Exam Topic 1) Which method of password cracking takes the most time and effort? A. Dictionary attack B. Shoulder surfing C. Rainbow tables D. Brute force Answer: D Explanation Brute-force attack when an attacker uses a set of predefined values to attack a target and analyze the response until he succeeds. Success depends on the set of predefined values. It will take more time if it is larger, but there is a better probability of success. In a traditional brute-force attack, the passcode or password is incrementally increased by one letter/number each time until the right passcode/password is found. Question #:35 - (Exam Topic 1) Why should the security analyst disable/remove unnecessary ISAPI filters? A. To defend against social engineering attacks B.

Which security feature on switchers leverages the DHCP snooping database to help prevent man-in-the-middle attacks? A. Spanning tree B. Dynamic ARP Inspection (DAI) C. Port security D. Layer 2 Attack Prevention Protocol (LAPP) Answer: B Explanation Dynamic ARP inspection (DAI) protects switching devices against Address Resolution Protocol (ARP) packet spoofing (also known as ARP poisoning or ARP cache poisoning). DAI inspects ARPs on the LAN and uses the information in the DHCP snooping database on the switch to validate ARP packets and to protect against ARP spoofing. ARP requests and replies are compared against entries in the DHCP snooping database, and filtering decisions are made based on the results of those comparisons. When an attacker tries to use a forged ARP packet to spoof an address, the switch compares the address with entries in the database. If the media access control (MAC) address or IP address in the ARP packet does not match a valid entry in the DHCP snooping database, the packet is dropped. Question #:55 - (Exam Topic 1) What is the known plaintext attack used against DES which gives the result that encrypting plaintext with one DES key followed by encrypting it with a second DES key is no more secure than using a single key? A. Man-in-the-middle attack B. 100% Success with DumpsPedia.com 27 of 368 Braindumps Questions ECCouncil - 312-50v12 B. Meet-in-the-middle attack C. Replay attack D. Traffic analysis attack Answer: B Explanation https://en.wikipedia.org/wiki/Meet-in-the-middle_attack The meet-in-the-middle attack (MITM), a known plaintext attack, is a generic space–time tradeoff cryptographic attack against encryption schemes that rely on performing multiple encryption operations in sequence. The MITM attack is the primary reason why Double DES is not used and why a Triple DES key (168-bit) can be bruteforced by an attacker with 256 space and 2112 operations. The intruder has to know some parts of plaintext and their ciphertexts. Using meet-in-the-middle attacks it is possible to break ciphers, which have two or more secret keys for multiple encryption using the same algorithm. For example, the 3DES cipher works in this way. Meet-in-the-middle attack was first presented by Diffie and Hellman for cryptanalysis of DES algorithm. Question #:56 - (Exam Topic 1) A network admin contacts you.

Extraction of cryptographic secrets through coercion or torture. D. Attempting to decrypt ciphertext by making logical assumptions about the contents of the original plaintext. Answer: C Explanation A powerful and often the most effective cryptanalysis method in which the attack is directed at the most vulnerable link in the cryptosystem - the person. In this attack, the cryptanalyst uses blackmail, threats, torture, extortion, bribery, etc. This method's main advantage is the decryption time's fundamental independence from the volume of secret information, the length of the key, and the cipher's mathematical strength. The method can reduce the time to guess a password, for example, for AES, to an acceptable level; however, it requires special authorization from the relevant regulatory authorities. Therefore, it is outside the scope of this course and is not considered in its practical part.

Something you are and something you remember B. Something you have and something you know C. Something you know and something you are D. Something you have and something you are Answer: B Explanation Two-factor Authentication or 2FA is a user identity verification method, where two of the three possible authentication factors are combined to grant access to a website or application.1) something the user knows, 2) something the user has, or 3) something the user is. The possible factors of authentication are: · Something the User Knows: This is often a password, passphrase, PIN, or secret question. To satisfy this authentication challenge, the user must provide information that matches the answers previously provided to the organization by that user, such as “Name the town in which you were born.” · Something the User Has: This involves entering a one-time password generated by a hardware authenticator. Users carry around an authentication device that will generate a one-time password on command. Users then authenticate by providing this code to the organization. Today, many organizations offer software authenticators that can be installed on the user’s mobile device. · Something the User Is: This third authentication factor requires the user to authenticate using biometric data. This can include 100% Success with DumpsPedia.com 32 of 368 Braindumps Questions ECCouncil - 312-50v12 fingerprint scans, facial scans, behavioral biometrics, and more. For example: In internet security, the most used factors of authentication are: something the user has (e.g., a bank card) and something the user knows (e.g., a PIN code). This is two-factor authentication. Two-factor authentication is also sometimes referred to as strong authentication, Two-Step Verification, or 2FA. The key difference between Multi-Factor Authentication (MFA) and Two-Factor Authentication (2FA) is that, as the term implies, Two-Factor Authentication utilizes a combination of two out of three possible authentication factors. In contrast, Multi-Factor Authentication could utilize two or more of these authentication factors. Question #:66 - (Exam Topic 1) A network administrator discovers several unknown files in the root directory of his Linux FTP server. One of the files is a tarball, two are shell script files, and the third is a binary file is named "nc." The FTP server's access logs show that the anonymous user account logged in to the server, uploaded the files, and extracted the contents of the tarball and ran the script using a function provided by the FTP server's software. The “ps” command shows that the “nc” file is running as process, and the netstat command shows the “nc” process is listening on a network port. What kind of vulnerability must be present to make this remote attack possible? A. File system permissions B. Privilege escalation C. Directory traversal D. Brute force login Answer: A Explanation File system permissions Processes may automatically execute specific binaries as part of their functionality or to perform other actions. If the permissions on the file system directory containing a target binary, or permissions on the binary itself, are improperly set, then the target binary may be overwritten with another binary using user-level permissions and executed by the original process. If the original process and thread are running under a higher permissions level, then the replaced binary will also execute under higher-level permissions, which could include SYSTEM. Adversaries may use this technique to replace legitimate binaries with malicious ones as a means of executing code at a higher permissions level. If the executing process is set to run at a specific time or during a certain event (e.g., system bootup) then this technique can also be used for persistence. 100% Success with DumpsPedia.com 33 of 368 Braindumps Questions ECCouncil - 312-50v12 Question #:67 - (Exam Topic 1) What does a firewall check to prevent particular ports and applications from getting packets into an organization?

A. 113 B. 69 C. 123 D. 161 Answer: C Explanation https://en.wikipedia.org/wiki/Network_Time_Protocol The Network Time Protocol (NTP) is a networking protocol for clock synchronization between computer systems over packet-switched, variable-latency data networks. NTP is intended to synchronize all participating computers within a few milliseconds of Coordinated 100% Success with DumpsPedia.com 36 of 368 Braindumps Questions ECCouncil - 312-50v12 Universal Time (UTC). It uses the intersection algorithm, a modified version of Marzullo's algorithm, to select accurate time servers and is designed to mitigate variable network latency effects. NTP can usually maintain time to within tens of milliseconds over the public Internet and achieve better than one millisecond accuracy in local area networks. Asymmetric routes and network congestion can cause errors of 100 ms or more. The protocol is usually described in terms of a client-server model but can easily be used in peer-to-peer relationships where both peers consider the other to be a potential time source. Implementations send and receive timestamps using the User Datagram Protocol (UDP) on port number 123. Question #:74 - (Exam Topic 1) Joseph was the Web site administrator for the Mason Insurance in New York, who's main Web site was located at www.masonins.com. Joseph uses his laptop computer regularly to administer the Web site. One night, Joseph received an urgent phone call from his friend, Smith. According to Smith, the main Mason Insurance web site had been vandalized! All of its normal content was removed and replaced with an attacker's message ''Hacker Message: You are dead! Freaks!” From his office, which was directly connected to Mason Insurance's internal network, Joseph surfed to the Web site using his laptop. In his browser, the Web site looked completely intact. No changes were apparent. Joseph called a friend of his at his home to help troubleshoot the problem. The Web site appeared defaced when his friend visited using his DSL connection. So, while Smith and his friend could see the defaced page, Joseph saw the intact Mason Insurance web site. To help make sense of this problem, Joseph decided to access the Web site using hisdial-up ISP. He disconnected his laptop from the corporate internal network and used his modem to dial up the same ISP used by Smith. After his modem connected, he quickly typed www.masonins.com in his browser to reveal the following web page: After seeing the defaced Web site, he disconnected his dial-up line, reconnected to the internal network, and used Secure Shell (SSH) to log in directly to the Web server. He ran Tripwire against the entire Web site, and determined that every system file and all the Web content on the server were intact. How did the attacker accomplish this hack? A. ARP spoofing B. SQL injection C. DNS poisoning D. Routing table injection Answer: C Question #:75 - (Exam Topic 1) You are the Network Admin, and you get a complaint that some of the websites are no longer accessible. You 100% Success with DumpsPedia.com 37 of 368 Braindumps Questions ECCouncil - 312-50v12 try to ping the servers and find them to be reachable. Then you type the IP address and then you try on the browser, and find it to be accessible. But they are not accessible when you try using the URL. What may be the problem? A. Traffic is Blocked on UDP Port 53 B. Traffic is Blocked on TCP Port 80 C. Traffic is Blocked on TCP Port 54 D. Traffic is Blocked on UDP Port 80 Answer: A Explanation Most likely have an issue with DNS. DNS stands for “Domain Name System.” It’s a system that lets you connect to websites by matching human-readable domain names (like example.com) with the server's unique ID where a website is stored. Think of the DNS system as the internet’s phonebook. It lists domain names with their corresponding identifiers called IP addresses, instead of listing people’s names with their phone numbers. When a user enters a domain name like wpbeginner.com on their device, it looks up the IP address and connects them to the physical location where that website is stored. NOTE: Often DNS lookup information will be cached locally inside the querying computer or remotely in the DNS infrastructure. There are typically 8 steps in a DNS lookup. When DNS information is cached, steps are skipped from the DNS lookup process, making it quicker. The example below outlines all 8 steps when nothing is cached. The 8 steps in a DNS lookup: 1. A user types ‘example.com’ into a web browser, and the query travels into the Internet and is received by a DNS recursive resolver; 2. The resolver then queries a DNS root nameserver; 3. The root server then responds to the resolver with the address of a Top-Level Domain (TLD) DNS server (such as.com or.net), which stores the information for its domains. When searching for example.com, our request is pointed toward the.com TLD; 4. The resolver then requests the.com TLD; 5. The TLD server then responds with the IP address of the domain’s nameserver, example.com; 6. Lastly, the recursive resolver sends a query to the domain’s nameserver; 7. The IP address for example.com is then returned to the resolver from the nameserver; 100% Success with DumpsPedia.com 38 of 368 Braindumps Questions ECCouncil - 312-50v12 8. The DNS resolver then responds to the web browser with the IP address of the domain requested initially; Once the 8 steps of the DNS lookup have returned the IP address for example.com, the browser can request the web page: 9. The browser makes an HTTP request to the IP address; 10. The server at that IP returns the webpage to be rendered in the browser. NOTE 2: DNS primarily uses the User Datagram Protocol (UDP) on port number 53 to serve requests. And if this port is blocked, then a problem arises already in the first step. But the ninth step is performed without problems.

This client uses the same hardware and software as many of the other clients on the network. The client can see the network, but cannot connect. A wireless packet sniffer shows that the Wireless Access Point (WAP) is not responding to the association requests being sent by the wireless client. What is a possible source of this problem? A. The WAP does not recognize the client’s MAC address B. The client cannot see the SSID of the wireless network C. Client is configured for the wrong channel D. The wireless client is not configured to use DHCP Answer: A Explanation https://en.wikipedia.org/wiki/MAC_filtering MAC filtering is a security method based on access control. Each address is assigned a 48-bit address, which is used to determine whether we can access a network or not. It helps in listing a set of allowed devices that you need on your Wi-Fi and the list of denied devices that you don’t want on your Wi-Fi. It helps in preventing unwanted access to the network. In a way, we can blacklist or white list certain computers based on their MAC address. We can configure the filter to allow connection only to those devices included in the white list. White lists provide greater security than blacklists because the router grants access only to selected devices. It is used on enterprise wireless networks having multiple access points to prevent clients from communicating with each other. The access point can be configured only to allow clients to talk to the default gateway, but not other wireless clients. It increases the efficiency of access to a network. The router allows configuring a list of allowed MAC addresses in its web interface, allowing you to choose which devices can connect to your network. The router has several functions designed to improve the network's security, but not all are useful. Media access control may seem advantageous, but there are certain flaws. On a wireless network, the device with the proper credentials such as SSID and password can authenticate with the router and join the network, which gets an IP address and access to the internet and any shared resources. MAC address filtering adds an extra layer of security that checks the device’s MAC address against a list of agreed addresses. If the client’s address matches one on the router’s list, access is granted; otherwise, it doesn’t join the network. 100% Success with DumpsPedia.com 44 of 368 Braindumps Questions ECCouncil - 312-50v12 Question #:90 - (Exam Topic 1) What is the proper response for a NULL scan if the port is open?

It is the wireless version of the phishing scam. An attacker fools wireless users into connecting a laptop or mobile phone to a tainted hot-spot by posing as a legitimate provider. This type of attack may be used to steal the passwords of unsuspecting users by either snooping the communication link or by phishing, which involves setting up a 100% Success with DumpsPedia.com 49 of 368 Braindumps Questions ECCouncil - 312-50v12 fraudulent web site and luring people there.” Fill in the blank with appropriate choice. A. Evil Twin Attack B. Sinkhole Attack C. Collision Attack D. Signal Jamming Attack Answer: A Explanation https://en.wikipedia.org/wiki/Evil_twin_(wireless_networks) An evil twin attack is a hack attack in which a hacker sets up a fake Wi-Fi network that looks like a legitimate access point to steal victims’ sensitive details. Most often, the victims of such attacks are ordinary people like you and me. The attack can be performed as a man-in-the-middle (MITM) attack. The fake Wi-Fi access point is used to eavesdrop on users and steal their login credentials or other sensitive information. Because the hacker owns the equipment being used, the victim will have no idea that the hacker might be intercepting things like bank transactions. An evil twin access point can also be used in a phishing scam. In this type of attack, victims will connect to the evil twin and will be lured to a phishing site. It will prompt them to enter their sensitive data, such as their login details. These, of course, will be sent straight to the hacker. Once the hacker gets them, they might simply disconnect the victim and show that the server is temporarily unavailable. ADDITION: It may not seem obvious what happened. The problem is in the question statement. The attackers were not Alice and John, who were able to connect to the network without a password, but on the contrary, they were attacked and forced to connect to a fake network, and not to the real network belonging to Jane.

System Hacking Answer: B Question #:107 - (Exam Topic 1) During a black-box pen test you attempt to pass IRC traffic over port 80/TCP from a compromised web enabled host. The traffic gets blocked; however, outbound HTTP traffic is unimpeded. What type of firewall is inspecting outbound traffic? A. Circuit B. Stateful C. Application D. Packet Filtering Answer: C Explanation https://en.wikipedia.org/wiki/Internet_Relay_Chat Internet Relay Chat (IRC) is an application layer protocol that facilitates communication in text. The chat process works on a client/server networking model. IRC clients are computer programs that users can install on their system or web-based applications running either locally in the browser or on a third-party server. 100% Success with DumpsPedia.com 52 of 368 Braindumps Questions ECCouncil - 312-50v12 These clients communicate with chat servers to transfer messages to other clients. IRC is a plaintext protocol that is officially assigned port 194, according to IANA. However, running the service on this port requires running it with root-level permissions, which is inadvisable. As a result, the well-known port for IRC is 6667, a high-number port that does not require elevated privileges. However, an IRC server can also be configured to run on other ports as well. You can't tell if an IRC server is designed to be malicious solely based on port number. Still, if you see an IRC server running on port a WKP such as 80, 8080, 53, 443, it's almost always going to be malicious; the only real reason for IRCD to be running on port 80 is to try to evade firewalls. https://en.wikipedia.org/wiki/Application_firewall An application firewall is a form of firewall that controls input/output or system calls of an application or service. It operates by monitoring and blocking communications based on a configured policy, generally with predefined rule sets to choose from. The application firewall can control communications up to the OSI model's application layer, which is the highest operating layer, and where it gets its name. The two primary categories of application firewalls are network-based and host-based. Application layer filtering operates at a higher level than traditional security appliances. This allows packet decisions to be made based on more than just source/destination IP Addresses or ports. It can also use information spanning across multiple connections for any given host. Network-based application firewalls Network-based application firewalls operate at the application layer of a TCP/IP stack. They can understand certain applications and protocols such as File Transfer Protocol (FTP), Domain Name System (DNS), or Hypertext Transfer Protocol (HTTP). This allows it to identify unwanted applications or services using a non-standard port or detect if an allowed protocol is being abused. Host-based application firewalls A host-based application firewall monitors application system calls or other general system communication. This gives more granularity and control but is limited to only protecting the host it is running on. Control is applied by filtering on a per-process basis. Generally, prompts are used to define rules for processes that have not yet received a connection. Further filtering can be done by examining the process ID of the owner of the data packets. Many host-based application firewalls are combined or used in conjunction with a packet filter.

TCP/UDP Port scanning D. Checking if the remote host is alive 100% Success with DumpsPedia.com 54 of 368 Braindumps Questions ECCouncil - 312-50v12 Answer: D Explanation Vulnerability scanning solutions perform vulnerability penetration tests on the organizational network in three steps: 1. Locating nodes: The first step in vulnerability scanning is to locate live hosts in the target network using various scanning techniques. 2. Performing service and OS discovery on them: After detecting the live hosts in the target network, the next step is to enumerate the open ports and services and the operating system on the target systems. 3. Testing those services and OS for known vulnerabilities: Finally, after identifying the open services and the operating system running on the target nodes, they are tested for known vulnerabilities.
