To ensure up-to-date protection against the latest security risks, perform a manual
update or
set a scheduled update for the following components:
-
Pattern files: These files are the Virus Pattern, Spyware Pattern, IntelliTrap
Pattern, and IntelliTrap Exception Pattern. These files contain the binary “signatures”
or
patterns of known security risks. When used in conjunction with the scan engine, IM Security is able to detect known risks
as they pass through Lync/Skype for Business Server. New pattern files are typically
released
at the rate of several per week.
-
Virus Scan Engine: This is the component that analyzes each file’s binary patterns
and
compares them against the binary information in the pattern files. If there is a match,
the
file is determined to be malicious.
-
URL Filtering Engine: IM Security
utilizes the Trend Micro URL Filtering Engine to
perform URL categorization and reputation rating based on the data supplied by the
Trend Micro Web Reputation feature.
