Interaction Between Nokia Intrusion Prevention and Nokia Firewall

Overview

Firewalls provide protection between the external networks and internal networks by blocking potentially malicious traffic from entering the internal network infrastructure. However, inherently firewalls need to allow SMTP/email, FTP, SIP/VoIP calls and other protocols with minimal payload security inspection. 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. Nokia Intrusion Prevention provides the flexibility to interact with Nokia Firewall, providing the most effective strategy for threat mitigation at both the perimeter and deep within the core. This paper explains the interaction between Nokia Intrusion Prevention and Nokia Firewall.
