Webwasher 6.0.1 Anti-Malware User's Guide - McAfee

Proactive Scanning Setup
The Proactive Scanning Setup section looks like this:
Content Security
Using this section, you can set one of three security levels to configure a general
Proactive Scanning policy.
After setting a general level, you can return to the Proactive Scanning tab
and proceed from there to the tabs for the various code types to fine-tune their
settings.
The general security levels are:
• Relaxed, Medium and Strict
For each level, a description is given here of how stringently suspicious code is
blocked at this level. Furthermore, a graphic is added for each level, showing
the ratio between the security achieved at this level and the risks of obtaining
false positives as well as false negatives.
False negatives are instances of malicious code that are not blocked at a particular
security level, although they should be.
False positives are instances of code that are blocked, although they are
actually not malicious. The latter situation is also known under the term of
overblocking.
