Nokia Intrusion Prevention and Nokia Firewall

Firewalls provide protection between the external networks and internal networks by blocking potentially malicious traffic from entering the internal network infrastructure.

This also allows external threat-sources to infect internal end-points and use them as threat sources. Firewall's deep packet inspection capabilities are not as strong as an Intrusion Prevention solution.
