What are system variables and how do they affect security?

What are system variables in the context of computer security?

System variables are dynamic values that can affect the behavior of a system, including security settings.

How do these variables impact the security of a system?

They can control access permissions, environment settings, and configurations that protect against vulnerabilities.

Can you give an example of a system variable that affects security?

Sure! An example is the 'PATH' variable, which determines the directories the system searches for executable files.

What should I do if I suspect a system variable has been compromised?

You should review the variable's settings, check for unauthorized changes, and restore it to a secure state.
