A vulnerability management framework is a set of processes and tools that helps an organization identify, assess, prioritize, remediate, and mitigate system vulnerabilities. A vulnerability management framework aims to reduce the attack surface and the risk of compromise by applying security patches, hardening configurations, implementing security controls, and monitoring the system status. A vulnerability management framework is an essential component of a security operations center (SOC). References: Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) - Cisco, page 2-14; 200-201 CBROPS - Cisco, exam topic 1.2.b

Network Address Translation (NAT) is the technology that allows a single IP address to send and receive traffic for multiple devices by modifying the IP header. NAT remaps one IP address space into another, enabling multiple devices to use a single public IP address to send and receive packets through the Internet2.

References := The concept of NAT and its role in network traffic management is detailed in networking resources and documentation, including those provided by network solution providers2.

Delivery is the fourth phase of the cyber kill chain, which is a model to describe the stages of a cyberattack. Delivery refers to the transmission of the weaponized payload to the target system, such as via email attachments, web links, USB drives, or network connections. Delivery does not necessarily imply successful installation or execution of the payload, which are subsequent phases of the kill chain. References := Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) - Cisco, page 31.

Full packet captures are essential for troubleshooting security and performance issues as they provide detailed information on network traffic (option B). They also allow for reassembling fragmented traffic from raw data, enabling analysts to review complete transactions or sessions (option C). References := Cisco Cybersecurity Operations Fundamentals - Module 3: Network Data and Event Analysis
