The packet capture shows that IP address 192.168.88.149, using source port 80 (common for HTTP traffic), initiated communication with IP address 192.168.88.12 at destination port 49098, using the TCP protocol, indicating a typical client-server interaction over the web.

= These explanations are based on general cybersecurity principles as outlined in Cisco’s training and certification content, such as the Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) and other related Cisco resources.

The security scenario involves protecting the company from known issues that trigger adware and addressing a recent incident that could harm the system.

This scenario involves identifying vulnerabilities (weaknesses in the system that can be exploited) and threats (potential harm that can exploit these vulnerabilities).

A vulnerability is an inherent flaw in the system, while a threat is an event or condition that has the potential to exploit the vulnerability.

The security engineer needs to assess both the vulnerabilities present and the threats that could exploit these vulnerabilities to implement effective protection measures.

 The discrepancy described suggests that the system had a Host Intrusion Detection System (HIDS) installed. HIDS are designed to monitor and analyze the internals of a computing system for signs of intrusion and policy violations. While they can detect unauthorized activities, they do not take direct action to stop an attack; this is typically the role of an intrusion prevention system. Therefore, the alert was generated, but no mitigation action was taken because the HIDS does not have the capability to intervene.
