An important task for the network monitoring solution is to check existing security systems, such as firewalls and virus scanners
, for operational reliability.
Because virus scanners
run with high access rights and are used at central points they offer highly attractive targets for attacks.
The white paper proposes that to detect Trojans, one must use a multi-level strategy and deploy multiple virus scanners
at the gateway, which would increase the percentage of known Trojans caught; and use content security with executable analysis to detect potentially malicious executables, analyse what they might do and prevent unknown Trojans from entering the network.
The principle functions as follows: virus scanners
must recognise as many "Malware" applications as possible - and thereby comprehend and process a large number of file formats.
The fact that virus scanners
only cover a portion of non-virus threats is well known.
The virus scanner
is by far the most popular - but not necessarily the best - defense against viruses.

Virus Checking: RTC blocks viruses invisible to virus scanners
They are formed by incorrectly configured mail servers or improperly written Email software and can bypass virus scanners
that don't know how to detect and then deal with them.
March 4 /PRNewswire/ -- RAE Internet and CyberSoft International are pleased to announce that the Message Processing Platform (MPP) using the Pattern Authority engine by CyberSoft International is one of the only email virus scanners
capable of detecting the dangerous Bagle.
Also, anti- virus scanners
also cannot detect attacks that are not carried in files or email messages.
and firewalls only protect against known network attacks and are unable to help in this instance.
