Virus and worm protection
Viruses and worms are most often targeted at Microsoft Windows operating systems or such
commonly used applications as IIS, Exchange, Outlook, or Word. Because the S8300, S8500,
and S8700 Media Servers are Linux-based and do not interface with these Microsoft products,
they have some degree of natural immunity. In addition, viruses and worms are most commonly
delivered by e-mail, by visiting infected Web sites, or by sharing disk drives.
The S8300, S8500, and S8700 Media Servers do not
Support incoming email and, therefore, do not forward e-mail
Contain the Internet Explorer Web browser
Share drives
All file transfers to the S8300, S8500, and S8700 Media Servers are restricted. software, and
patchfiles are cryptographically signed to prevent introduction of unwanted software. In addition
to this natural immunity, the files and file systems of the S8700 and the S8300 servers are
monitored by Tripwire.
