The attack vector score in the Common Vulnerability Scoring System (CVSS) reflects how a vulnerability can be exploited. A higher score is given when the attack can be conducted remotely, making it easier for an attacker to exploit the vulnerability without physical access to the vulnerable component3. References: The CVSS specification document provides a detailed explanation of how the attack vector score is determined, emphasizing the impact of the ease of exploitation on the score

 DNS amplification is a type of Distributed Denial of Service (DDoS) attack where an attacker uses publicly accessible open DNS servers to flood a target with DNS response traffic. The goal is to overwhelm the target with traffic, causing a denial of service.

• A: Stateful inspection tracks the state of network connections, such as TCP streams, to determine if a packet is part of an established connection.
• B: Deep packet inspection examines the data part (payload) of a packet and can identify, block, or reroute packets with specific types of malware. Stateful inspection does not inspect the payload for malware.

Port scanning is a technique that an attacker uses to discover which network ports are open, closed, or filtered on a target device. By sending packets to different ports and observing the responses, an attacker can identify the services and applications running on the device, as well as potential vulnerabilities that can be exploited. Port scanning is a common reconnaissance activity that precedes an attack. References: Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) - Cisco, page 2-6; 200-201 CBROPS - Cisco, exam topic 1.1.a

Full packet capture (FPC) is a valuable tool for investigating security breaches because it provides comprehensive data that can be used to reconstruct the event and identify the root cause. By capturing every packet, FPC allows engineers to see exactly what took place during the breach, including the TCP flags set within each packet, which can help focus on suspicious packets to identify malicious activity. It also collects metadata, including IP traffic packet data that is sorted, parsed, and indexed, and provides the full TCP streams to follow the metadata to identify the incoming threat

The principle of least privilege states that users and processes should be granted only the minimum permissions necessary to perform their specific role or function within an organization. This reduces the attack surface and limits the potential damage of a compromised account or process. References:

A host-based intrusion detection system (HIDS) monitors a computer system for suspicious activity by analyzing events occurring within that host. It can detect malicious activities and security policy violations by examining system calls, application logs, file-system modifications (such as rootkit installations), and other host activities. HIDS is an essential component in safeguarding the IT infrastructure against unauthorized access and security breaches.

 The average time taken by a Security Operations Center (SOC) to detect and resolve incidents is a critical metric for evaluating its effectiveness and scope. This metric reflects the SOC’s efficiency in identifying security threats and its ability to respond and mitigate those threats promptly. It encompasses the entire incident lifecycle, from initial detection to final resolution, providing a comprehensive measure of the SOC’s performance1.
