2Product Information

2.1 Mode of Operation

Microsoft ISA Server
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 http://www.microsoft.com/isaserver.
AntiVir ISA Server
Product Information
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 Configuration of AntiVir ISA Service – Page 23 contains 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.
To begin with, two important items of information:
Losing important data often has dramatic consequences. Not even the best antivirus program can completely protect you from data loss.
X
Back up your files regularly.
Product Information
Antivirus programs are reliable only if kept up to date.
X
Schedule regular updates for AntiVir ISA Server (this manual teaches you how).
