Which of the following steps will help in system or host hardening? Each correct answer represents a
complete solution. Choose two.

A.
Installing updated device drivers.

B.
Adding users to the administrators group.

C.
Installing or applying a patch on the host provided by the operating system manufacturer.

D.
Disabling unnecessary services from the host.

Explanation:
The following steps will help in system or host hardening:
Disabling unnecessary services from the host.
Installing or applying a patch on the host provided by the operating system manufacturer.
System hardening is a term used for securing an operating system. It can be achieved by installing
the latest service packs, removing unused protocols and services, and limiting the number of users
with administrative privileges.
Answer A and B are incorrect. Installing updated device drivers on the computer or adding users to
the administrators group will not help in system or host hardening. Adding users to the
administrators group will give users unnecessary permission to the computer. This will be a security
issue.
