CORRECT TEXT
Fill in the blank with the appropriate term. A ______________ is a set of tools that take
Administrative control of a computer system without authorization by the computer owners and/or
legitimate managers.

Answer: rootkit

Explanation:

A rootkit is a set of tools that take Administrative control of a computer system without
authorization by the computer owners and/or legitimate managers. A rootkit requires root access
to be installed in the Linux operating system, but once installed, the attacker can get root access
at any time. Rootkits have the following features:
They allow an attacker to run packet sniffers secretly to capture passwords.
They allow an attacker to set a Trojan into the operating system and thus open a backdoor for
anytime access.
They allow an attacker to replace utility programs that can be used to detect the attacker’s activity.
They provide utilities for installing Trojans with the same attributes as legitimate programs.
