Symantec intrusion prevention signatures not updating

HIDS (Host based Interusion dtection system)Host Intrusion Detection Systems are run on individual hosts or devices on the network. Signature Based A signature based IDS will monitor packets on the network and compare them against a database of signatures or attributes from known malicious threats.A HIDS monitors the inbound and outbound packets from the device only and will alert the user or administrator of suspicious activity is detected. This is similar to the way most antivirus software detects malware.

Similarly, the IPS engine’s role in the Norton security suite is to carefully examine the traffic that the firewall has already allowed.Some host intrusion prevention systems allow users to send logs of malicious activity and fragments of suspicious code directly to the vendor for analysis and possible identification.Most host intrusion prevention systems use known attack patterns, called signatures, to identify malicious activity.Firewalls also block network communication on non-standard ports, which are generally not used by legitimate programs and services.On the other hand, an IPS goes one step further, and examines all network traffic that is allowed through the firewall.
