Endpoint Security Concepts

A security analyst determines that a hacker gained root access to an enterprise Linux server. The hacker accessed the server as a guest, used a program to bypass the root password, and then, as the root user, killed essential server processes.

What type of endpoint attack is this?

  • A Privilege escalation
  • B DDoS
  • C Brute force
  • D Buffer overflow
Explanation

Privilege escalation occurs when an attacker obtains permissions beyond their originally authorized level, such as moving from guest access to root access on a Linux server. Root-level process termination is possible because of those elevated privileges.
