Study Notes
Internet Worm Attacks
- Morris worm (1988) is considered one of the first major Internet crime cases.
- Slammer worm exploited a vulnerability in Microsoft SQL Server.
Attack Groups
- Lazarus Group is a Russian hacking group associated with attacks on Ukraine.
- Sandworm is another Russian hacking group with a history of disruptive attacks.
Attack Techniques
- Target of opportunity attack exploits readily available vulnerabilities in a system.
- Specific target attack is directed at a particular target with a specific vulnerability.
- Script kiddies are individuals without advanced skills who use pre-made scripts for attacks.
Security Models
- The operational model of security is Prevention = Protection + (Detection x Response).
- Secure deployments rely on least privilege, separation of privilege, and defense in depth.
Specific Security Terms
- Telephony hacking refers to unauthorized access to a phone network.
- Separation of concern is a design concept to isolate components preventing interference.
- Information classification uses categories like High, Medium, Low, Confidential, Private, and Public.
Agreements & Policies
- Memorandums of Understanding (MOUs) outline partnership terms.
- Service Level Agreements (SLAs) define agreed-upon performance.
- Policies are high-level statements of goals, and recommendations detail specific actions.
Social Engineering
- Social engineering exploits human psychology to gain unauthorized access.
- Social engineering works because people want to be helpful.
- Pharming redirects users to fake websites by modifying host files.
- Shoulder surfing is directly observing a user entering information.

- Spanning trees prevent loops in network switching.
- Firewalls utilize implicit deny rules to block traffic not explicitly permitted.
- SSL Accelerators provide SSL/TLS encryption capabilities on a broader level than the web server itself
- Switches connect network segments.
- Near-field communication (NFC) allows short-range device communication.
- 802.11a operates in a 5 GHz spectrum.
Intrusion Detection and Protection
- Host-based IDSs monitor activity on a specific host.
- Banner grabbing gathers information from a service display.
- Hardware security modules (HSMs) manage encryption keys.
- Secure boot ensures only trusted anti-malware programs load.
- chmod modifies permissions in a Linux system.
- Network scanners probe for system weaknesses.
Malware
- Malware is malicious software.
- SYN flooding is a denial-of-service attack.
- Packet sniffing examines all network traffic.

- Tracert provides a network route trace.
- Wireshark analyzes and replays network traffic.
- Network protocols and communications.
Cloud Computing Security
- Platform as a Service (PaaS) is a set of multiple software offerings in the cloud.
- VPNs allow connections in and out of a virtual private cloud.
Risk Management
- Qualitative risk assessment subjectively evaluates impact.
- Tangible impacts are measurable effects.
- Risk mitigations are methods to counter risks.
- Risk register is a list of project risks.
Incident Response
- Include business personnel in incident response efforts.
- Incident response is a layered process.
- Threat Diamond is used in threat intel.
