IDP Service Groups
An IDP service group is a set of related packet inspection signatures.
The n/a service group is for signatures that are not for a specific service.
SPAM
Spam is unsolicited “junk” e-mail sent to large numbers of people to promote products or
services.
Stream Media
A Stream Media attack occurs when a malicious network node downloads an
overwhelming amount of media stream data that could potentially exhaust the entire
system. This method allows users to send small requests messages that result in the
streaming of large media objects, providing an opportunity for malicious users to exhaust
resources in the system with little effort expended on their part.
Tunnel
A Tunneling attack involves sending IPv6 traffic over IPv4, slipping viruses, worms and
spyware through the network using secret tunnels. This method infiltrates standard
security measures through IPv6 tunnels, passing through IPv4 undetected. An external
signal then activates the malicious files to wreak havoc from inside the network.
Virus/Worm
A computer virus is a small program designed to corrupt and/or alter the operation of
other legitimate programs. A worm is a program that is designed to copy itself from one
computer to another on a network. A worm’s uncontrolled replication consumes system
resources, thus slowing or stopping other tasks.
Web Attack
Web attacks refer to attacks on web servers such as IIS (Internet Information Services).
