Security is a process that is:

A.
Continuous

B.
Indicative

C.
Examined

D.
Abnormal

Explanation:
Security is a continuous process; as such you must closely monitor your systems on a regular basis.
Log files are usually a good way to find an indication of abnormal activities. However some care must
be exercise as to what will be logged and how the logs are protected. Having corrupted logs is about
as good as not having logs at all.
