Which of the following is true of privilege escalation?

Explanation:
Privilege escalation occurs when someone obtains, without authorization, the rights and privileges of a different user. Privilege escalation usually occurs by logging in to a system using your valid user account and then finding a way to access files that you do not have permissions to access. This often involves invoking a program that can change your permissions, such as Set User ID (SUID), or invoking a program that runs in an administrative context.

There are several methods of dealing with privilege escalation can lead to denial-of-service (DoS) attacks. An example of privilege escalation is gaining access to a file you should not access by changing the permissions of your valid account.

Horizontal escalation is movement to an account on the same level, such as from a regular user another regular user.

Vertical escalation is movement to an account on a different level, such as from a regular user to an administrator.

Privilege escalation is never granted freely. It is an attack.
