ClamAV file analysis
The types of files that the Stormshield Network firewall antivirus service must analyze can be configured in this menu.
|Analyze compressed executable files||This option enables the decompression engine (Diet, Pkite, Lzexe, Exepack, etc.).|
|Analyze archives||This option enables the extraction engine and makes it possible to analyze archives (zip, arj, lha, rar, cab, etc.)|
|Block encrypted or password-protected files||This option allows blocking files that are encrypted or protected by a password.|
|Block unsupported file formats||This option allows blocking file formats that the antivirus is unable to scan.|
Advanced antivirus file analysis
|Inspect archives||This option enables the extraction engine and makes it possible to analyze archives (zip, arj, lha, rar, cab, etc.).|
|Block password-protected files||This option allows blocking password-protected files.|
|Activate heuristic analysis||Heuristic analysis is a method used to detect new viruses as well as new variants of known viruses, and is based on the assumed behavior of a program in order to determine whether such a program is a virus. This method is not to be confused with statistical analysis, which operates by looking up a repository of known viruses.
Heuristic analysis therefore makes it possible to detect viruses that have not yet been referenced in an antivirus engine vendor's repository.
This option is not supported on the following firewall models: SN160(W), SN210(W) and SN310.
