Deep packet inspection (DPI) is an advanced method of examining and managing network traffic. It is a form of packet filtering that locates, identifies, classifies, reroutes or blocks packets with specific data or code payloads that conventional packet filtering, which examines only packet headers, cannot detect. Next-generation firewalls (NGFWs) are deep-packet inspection firewalls that move beyond port/protocol inspection and blocking to add application-level inspection, intrusion prevention, and bringing intelligence from outside the firewall. Enabling Deep Packet Inspection. For application and application category specific configuration to take affect, you must first enable Deep Packet Inspection (DPI). Deep packet inspection is a methodology that network security professionals have been doing for many years. It involves looking at the data going over the network and determining if anything malicious is going on based on what's in those packets. Deep packet inspection is a type of data processing that inspects in detail the data being sent over a computer network, and usually takes action by blocking, re-routing, or logging it accordingly. Deep packet inspection is often used to ensure that data is in the correct format, to check for malicious code, eavesdropping, and internet censorship, among other purposes. There are multiple headers for IP packets; network equipment only needs to use the first of these for normal operation, but use A deep packet inspection firewall tracks the progress of a web browsing session and is capable of noticing whether a packet payload, when assembled with other packets in an HTTP server reply, constitutes a legitimate HTML formatted response. How to choose the right type of firewall Aug 24, 2017 · But, it doesn’t seem to offer any of the more advanced security features to protect against malware/viruses, for example. I'm examining the options for deep packet inspection, streaming malware scanning, and intrusion detection. The problem is that such routers/firewalls that are affordable seem to be a big bottleneck in terms of throughput.
May 30, 2020 · This issue can occur if the user is using a router that has stateful packet inspection (SPI) enabled. WORKAROUND Warning This workaround may make a computer or a network more vulnerable to attack by malicious users or by malicious software such as viruses.

This type of firewall is very thorough and provides the best level of security. They are touted as next generation firewalls because they use the deep packet inspection architecture which means checking what the packet contains before it is passed.
