Study Notes
- Vulnerability management programs primarily aim to identify, prioritize, and remediate vulnerabilities before they can be exploited.
- Modern enterprise systems are characterized by containing thousands of undiscovered security vulnerabilities.
- Ignoring vulnerabilities in non-critical systems is not a step in an effective vulnerability management program.
- When developing a vulnerability management program, an organization should first identify internal and external requirements for vulnerability scanning.
- PCI DSS and FISMA specifically mandate the implementation of a vulnerability management program.
- A common misconception about PCI DSS is that it is a standard maintained by an industry group (PCI SSC).
- PCI DSS requires organizations to run vulnerability scans quarterly and after significant network changes.
- Qualified personnel must conduct internal vulnerability scans for PCI DSS compliance.
- FISMA requires government agencies and organizations operating systems on their behalf to comply with a series of security standards based on system impact.
- In FIPS 199, a 'High' impact is defined as a severe or catastrophic adverse effect on organizational operations with respect to Confidentiality.
- According to NIST Special Publication 800-53, a basic requirement for vulnerability scanning for organizations subject to FISMA is scanning for vulnerabilities when new vulnerabilities are identified.
- The organization uses only manual processes to analyze vulnerability scan reports is NOT a control enhancement described in NIST 800-53.
- Many organizations mandate vulnerability scanning in corporate policy because vulnerability management is a critical component of information security.
- An important question to consider when identifying scan targets is the data classification of the information processed.
- According to Figure 3.2, the total number of hosts in the domain is 65535.
- Administrators supplement asset inventory with additional information to determine which systems are critical and noncritical.
- According to Figure 3.3, the Launch setting for the Nessus scan is Weekly.
- How often an organization decides to conduct vulnerability scans is influenced by the organization's risk appetite.
- Nessus is an example of a vulnerability scanning tool.
- Determining the scope of vulnerability scans involves considering what systems and networks will be included in the vulnerability scan.
- Judicious use of network segmentation enables isolation of critical systems for PCI DSS compliance.
- Scan sensitivity levels in vulnerability scanning serve to determine the types of checks performed by the scanner.
- Saving common configuration settings in templates allows efficient reuse of work, saving time and reducing errors.
- Disabling unnecessary plug-ins in a vulnerability scanner improves the speed of the scan.
- Credentialed scans retrieve configuration information from target servers.
- Admins should provide a read-only account on the server for credentialed scans.
- The 'inside-out' vulnerability scan approach is Agent-based scanning.
- Conducting scans from a variety of scan perspectives aims to gain different views into vulnerabilities from different network locations.
- Administrators should conduct regular maintenance of their vulnerability scanner to ensure the scanning software and vulnerability feeds remain up-to-date.
- According to Figure 3.11, Detection, Remediation, and Testing are the components of Vulnerability Management Life Cycle.
- Cybersecurity analysts spend a significant amount of time analyzing reports generated by vulnerability scanners.
- A primary task for a trained analyst interpreting vulnerability scan results is eliminating false positive reports.
- According to Figure 4.1, the Nessus vulnerability scanner reports that the SSH service supports weak encryption algorithms.
- According to Figure 4.1, the severity of the vulnerability reported by Nessus is Medium.
- The 'See Also' section of a vulnerability scan report typically provides references to external resources for more information.
- The purpose of the 'Output' section in a vulnerability scan report is to show the verbatim output from the remote system.
- The port/hosts section of a vulnerability scan report specifies the server(s) and specific services affected by the vulnerability.
- CVSS stands for Common Vulnerability Scoring System.
- The Access Vector Metric describes how an attacker would exploit the vulnerability.
- According to Table 4.1, an access vector score of 1.000 is assigned if the attacker can exploit the vulnerability remotely over a network.
- According to Table 4.2, a score of 0.610 is assigned if exploiting the vulnerability requires "somewhat specialized" conditions.
- A 'false positive' error in vulnerability scanning means the scanner reported a vulnerability that doesn't exist.
- Documenting exceptions to vulnerability remediation is important to avoid future scans from reporting the same issue.
- Vulnerability scanners report detailed information, including informational results, when run using default configurations.
- According to Figure 4.3, a cybersecurity analyst should first focus on High-severity vulnerabilities when encountering a scan report.
- The type of vulnerability described as a flaw in the Windows HTTP stack in Figure 4.6 is Missing Patch Vulnerability.
- The CVSS base score for the critical vulnerability shown in Figure 4.6 is 10.0.
- According to Figure 4.6, AV:N in the CVSS vector tells us that the vulnerability can be exploited remotely.
- According to Figure 4.7, the supported operating system is Microsoft Windows Server 2003.
- When an organization must continue using an unsupported operating system, isolate the system and apply compensating controls.
- The goal of a buffer overflow attack is to overwrite other information in memory.
- Privilege escalation is an attack that increases the level of access to a target system.
- The primary risk associated with arbitrary code execution vulnerabilities is that an attacker can run software of their choice on the targeted system.
- A key characteristic of remote code execution vulnerabilities is that they can be exploited over a network connection without physical access.
- The primary security risk associated with using insecure protocols like Telnet and FTP is these protocols lack encryption, exposing credentials and data.
- The main concern with debug modes on production servers is they provide detailed information that can assist attackers.
- According to Figure 4.12, SSL 3.0 is no longer acceptable for secure communications.
- Administrators should disable support for older protocols and support only newer protocols for servers supporting outdated versions of SSL and TLS.
- According to Figure 4.13, the set of supported ciphers on the affected server requires altering.
- A common error related to digital certificates is a mismatch between the Name on the Certificate and the Name of the Server.
- The purpose of a Domain Name System (DNS) is to translate domain names to IP addresses.
- A DNS amplification attack uses spoofed DNS requests to overwhelm a target with large responses.
- The primary risk associated with internal IP disclosure is that it allows attackers to learn more about the internal configuration of a firewalled network.
- The purpose of Network Address Translation (NAT) is to map public IP addresses to private IP addresses.
- The role of a hypervisor in a virtualized environment is to mediate access to underlying hardware resources.
- A virtual machine escape vulnerability is a vulnerability that allows a virtual machine to access the host operating system.
- Security measures for the management interface for a virtual infrastructure should use strong multifactor authentication and prevent direct access from public networks.
- A key consideration for securing virtual guest machines is that they should be promptly patched to correct security vulnerabilities.
- A significant concern for virtual networks is that communications between virtual machines may never touch a physical network.
- Cross-site scripting (XSS) is a type of attack that involves an attacker embedding scripting commands on a website.
