Explanation:
“Other security packages, such as the popular Tripwire data integrity assurance
packages, also provide a secondary antivirus functionality. Tripwire is designed to alert
administrators of unauthorized file modifications. It’s often used to detect web server defacements
and similar attacks, but it also may provide some warning of virus infections if critical system
executable files, such as COMMAND.COM, are modified unexpectedly. These systems work by
maintaining a database of hash values for all files stored on the system. These archive hash
values are then compared to current computed values to detect any files that were modified
between the two periods.” Pg. 224 Tittel: CISSP Study Guide
