Which of the following will BEST protect against malicious activity by a former employee?

A.
Preemployment screening

B.
Close monitoring of users

C.
Periodic awareness training

D.
Effective termination procedures

Explanation:

When an employee leaves an organization, the former employee may attempt to use their
credentials to perform unauthorized or malicious activity. Accordingly, it is important to ensure
timely revocation of all access at the time an individual is terminated. Security awareness training,
preemployment screening and monitoring are all important, but are not as effective in preventing
this type of situation.
