In this field… Do this…
Pass safe file types
without scanning
Select this option to accept common file types that are known to
be safe, without scanning them.
Safe files types are:
• MPEG streams
• RIFF Ogg Stream
• MP3
• PDF
• PostScript
• WMA/WMV/ASF
• RealMedia
• JPEG - only the header is scanned, and the rest of
the file is skipped
Selecting this option reduces the load on the gateway by skipping
safe file types. This option is selected by default.
Status
Maximum nesting level Type the maximum number of nested content levels that
VStream Antivirus should scan.
Setting a higher number increases security. Setting a lower
number prevents attackers from overloading the gateway by
sending extremely nested archive files.
The default value is 5 levels.
