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.
