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

 Agent-based protection is a type of endpoint security that uses software agents installed on the devices to monitor and protect them. Agent-based protection can collect and detect all traffic locally, which means it can operate without relying on a network connection or a centralized server. Agent-based protection can also provide more granular and comprehensive visibility and control over the devices. References: https://learningnetworkstore.cisco.com/on-demand-e-learning/understanding-cisco-cybersecurity-operations-fundamentals-cbrops-v1.0/CSCU-LP-CBROPS-V1-028093.html (Module 2: Security Concepts, Lesson 2.3: Endpoint Security)

 Availability is one of the three pillars of the CIA triad, a model that defines the principles of information security. Availability describes the concept of data consistently and readily being accessible for legitimate users. Availability ensures that the network and systems are operational and resilient to disruptions, such as denial-of-service attacks, hardware failures, or natural disasters. Availability also involves maintaining backup and recovery procedures, load balancing, and redundancy mechanisms. References:

When a system is overwhelmed with alerts, designing criteria for reviewing alerts can help prioritize and manage them more effectively. This approach allows for a structured review process that can distinguish between false positives, false negatives, and legitimate alerts, reducing the overall number of alerts that require attention3.

References := The strategy of designing criteria for reviewing alerts is recommended in cybersecurity best practices to manage alert fatigue and improve the efficiency of security operations3.

 The alert from the Cisco ASA device and the numerous activity logs are examples of circumstantial evidence. Circumstantial evidence is evidence that relies on an inference or deduction to connect it to a conclusion of fact, such as a security incident or an attack. Circumstantial evidence does not directly prove the fact in question, but rather suggests or implies it. In this case, the alert and the logs indicate that a TCP connection attempt was denied by an access group, but they do not directly prove that an attack occurred or who was behind it. There could be other explanations for the denied connection, such as a misconfiguration, a network error, or a legitimate request. Therefore, this type of evidence is circumstantial and requires further investigation and analysis to confirm or rule out the possibility of an attack. References := Circumstantial evidence - Wikipedia; Circumstantial Evidence - Definition, Examples, Cases, Processes; Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) - Cisco, page 92.

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

The user-agent HTTP header field is used in forensics to identify the type of browser used. It contains a characteristic string that allows network protocol peers to identify the operating system and browser of the web-server. This information is crucial in forensic analysis as it can provide insights into the client’s environment1.

References := The importance of the user-agent string in identifying the browser type is discussed in various technical resources, including the Wikipedia page on HTTP header fields2 and articles on GeeksforGeeks1.
