Intrusion Prevention scans all

the network traffic to and from

your computer and compares

this information against a set of

attack signatures. Attack

signatures contain the

information that identifies an

attacker's attempt to exploit a

known vulnerability in the

operating system or in a

program. If the information

matches an attack signature,

Intrusion Prevention blocks the

traffic from the suspicious

computer.

The following are some activities

that you can do using the

Intrusion Prevention options:

1 View the list of Intrusion

Prevention signatures.

1 Exclude individual signatures

from being monitored.

1 Specify whether or not you

must be notified when

Intrusion Prevention

signatures are detected.

1 Activate AutoBlock for a

specified duration to block

all incoming traffic from a

computer that continues to

attack your system.

1 View, restrict, or unblock the

list of computers that

AutoBlock blocks.

1 View or unblock the list of
