 When a server is experiencing high CPU and memory load, the first step is to identify the processes that are consuming the most resources. The command “ps -ef” is used to display information about all the running processes, including their IDs, memory and CPU usage, and the commands that started them. This allows the engineer to pinpoint which processes are responsible for the high load and take appropriate action, such as terminating unnecessary processes or optimizing resource usage345. References: Various resources on server management and troubleshooting recommend using the “ps -ef” command as a starting point for investigating high resource usage on servers

In the Common Vulnerability Scoring System (CVSS), attack complexity refers to the conditions beyond the attacker’s control that must exist for the vulnerability to be successfully exploited.

This includes factors such as the need for user interaction, the presence of specific configurations, or network conditions that are not easily controlled by the attacker.

A high attack complexity means that these external factors make exploitation more difficult, while a low attack complexity indicates that fewer such conditions are required.

Cybersecurity Frameworks and Metrics

 The principle of least privilege is a security best practice that states that an employee should have access to only the minimum amount of resources and permissions needed to perform their job function. This principle reduces the attack surface and the potential damage that can be caused by a compromised account, a malicious insider, or human error. The principle of least privilege can be enforced by using role-based access control (RBAC) and regular audits. References: Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) - Cisco, page 1-10; 200-201 CBROPS - Cisco, exam topic 1.2.a
