Digital certificates are essential for decrypting ingress and egress perimeter traffic, as they provide the necessary encryption keys for secure communications. By using digital certificates, network security devices can inspect the decrypted traffic to detect any malicious outbound communications that may indicate command-and-control activity.

• The weaponization step in the Cyber Kill Chain Model involves the creation or use of a specific weapon (malware, exploit) designed to leverage a vulnerability.
• This phase follows the reconnaissance phase where the attacker gathers information and precedes the delivery phase where the weapon is delivered to the target.
• Developing specific malware to exploit a vulnerable server is a precise example of weaponization.

In cybersecurity, a threat is any potential malicious attack or event that can harm an organization, while a risk is the potential damage or loss that could occur if a threat exploits a vulnerability. Therefore, risk is considered the intersection of threats and vulnerabilities, representing the likelihood and impact of a threat materializing.

 The unauthorized usage of “Tcpdump” tool indicates that the malicious insider was attempting to obtain all information within datagrams passing through a specific interface on the network. Tcpdump allows users to capture packet data from a live network or read packets from a previously saved capture file. References := Cisco CyberOps - Module 3: Network Data and Event Analysis

Rule-based detection involves identifying malicious activities based on predefined rules or patterns of known attacks; it does not adapt or change with new data. In contrast, behavioral detection adapts over time by learning from new data; it identifies malicious activities based on deviations from established norms or behaviors. References: Cisco Certified CyberOps Associate Overview, Section 1.0: Security Concepts, Subsection 1.1: Compare and contrast the characteristics of data obtained from taps, NetFlow, and packet capture)

• The exhibit shows an HTTP GET request with a parameter that includes ; /bin/sh -c id.
• This indicates a command injection attempt, where the attacker is trying to execute shell commands on the server.
• Command injection vulnerabilities allow an attacker to execute arbitrary commands on the host operating system via a vulnerable application.
• The use of /bin/sh and the -c flag is typical in command injection exploits to run shell commands, such as id, which returns user identity information.
