Explanation:
Vulnerability analysis (also known as vulnerability assessment) tools test to determine whether a
network or host is vulnerable to known attacks. Vulnerability assessment represents a special case of
the intrusion detection process. The information sources used are system state attributes and
outcomes of attempted attacks. The information sources are collected by a part of the assessment
engine. The timing of analysis is interval-based or batch-mode, and the type of analysis is misuse
detection. This means that vulnerability assessment systems are essentially batch mode misuse
detectors that operate on system state information and results of specified test routines.
