Mode of Operation

Microsoft Internet Security and Acceleration (ISA) Server offers an easy to 
configure Internet connection. It integrates an extendible Firewall and a Webcache 
(Proxyserver), where Microsoft ISA Server is based on the Windows security 
standards and directives.

You can find complete information on Microsoft ISA Server in the documentation 
and online at 

.

AntiVir ISA Server scans the files sent via Microsoft ISA Server for viruses and 
unwanted programs. This protects the HTTP traffic. It supports FTP protocol if 
processed by HTTP (FTP over HTTP). 

HTTPS is not currently supported, so the data sent and received via this protocol 
is not scanned for malware. The HTTPS requests are simply forwarded. Therefore, 
you can use Microsoft ISA Server for HTTPS, but without scanning by AntiVir ISA 
Server!

The software is deeply integrated within AntiVir ISA Server, ensuring high 
performance. Due to its modular structure and implementation, the AntiVir ISA 
Server does not usually require restarting of the Microsoft ISA Server when its 
configuration is changed. 

Files are scanned for viruses or unwanted programs by the powerful AntiVir Search 
Engine, which supports all known archive types (ZIP, RAR, GZIP, ARJ, LZH, LHA, 
ACE, etc.).

The virus definition files (VDF) and for the AntiVir Search Engine are updated 
automatically. Chapter

more information on this topic.

AntiVir ISA Server supports Microsoft ISA Server 2000 and 2004. There is a single 
program pack for both versions. The installation wizard automatically detects the 
version of your ISA Server.

You can configure AntiVir ISA Server using a graphical user interface integrated 
with MMC on Microsoft ISA Server.
