Interaction Between: Nokia Intrusion Prevention and Nokia Firewall
Firewalls provide protection between external networks and internal networks by blocking potentially malicious traffic from entering the internal network infrastructure. However, firewalls inherently need to allow SMTP/email, FTP, SIP/VoIP calls, and other protocols with minimal payload security inspection, which may also allow external threat sources to infect internal end-points and use them as threat sources. A firewall's deep-packet inspection capabilities are not as strong as an Intrusion Prevention System (IPS). Nokia Intrusion Prevention provides the flexibility to interact with Nokia Firewall, providing the most effective strategy for threat mitigation, both at the perimeter and deep within the core. This paper explains the interaction between Nokia Intrusion Prevention and Nokia Firewall.
