TotalSecure Configuration Task List

•Restrict Transfer of password-protected Zip files - Disables the transfer of password protected ZIP files over any enabled protocol. This option only functions on protocols (e.g. HTTP, FTP, SMTP) that are enabled for inspection.

•Restrict Transfer of MS-Office type files containing macros (VBA 5 and above) - Disables the transfers of any MS Office 97 and above files that contain VBA macros.

•Restrict Transfer of packed executable files (UPX, FSG, etc.) - Disables the transfer of packed executable files. Packers are utilities which compress and sometimes encrypt executables. Although there are legitimate applications for these, they are also sometimes used with the intent of obfuscation, so as to make the executables less detectable by anti-virus applications. The packer adds a header that expands the file in memory, and then executes that file. SonicWALL Gateway

Anti-Virus currently recognizes the most common packed formats: UPX, FSG, PKLite32, Petite, and ASPack. additional formats are dynamically added along with SonicWALL GAV signature updates.
