Deep packet inspection (DPI) is a type of data processing that inspects in detail the data being sent over a computer network, and may take actions such as alerting, blocking, re-routing, or logging it accordingly.
TCP/IP packets that are being sent out of the internal network are examined via a router, firewall, or similar edge device. Packets that do not meet security policies are not allowed to leave – they are denied "egress". [1] Egress filtering helps ensure that unauthorized or malicious traffic never leaves the internal network.
A distributed firewall is a security application on a host machine of a network that protects the servers and user machines of its enterprise's networks against unwanted intrusion. A firewall is a system or group of systems ( router , proxy , or gateway ) that implements a set of security rules to enforce access control between two networks to ...
An area is broken down further into sections, each of which contains detailed specifications of information security best practice. Each statement has a unique reference. For example, SM41.2 indicates that a specification is in the Security Management aspect, area 4, section 1, and is listed as specification No. 2 within that section.

The node designated as DMZ host is the downstream firewall of the actual DMZ (perhaps the router itself isn't part of a home network) The node runs a powerful firewall capable of regulating internal security; The sheer number of ports is too great for the port-forwarding feature; Correct port forwarding rules could not be formulated in advance
The ten rules are: [1] Avoid complex flow constructs, such as goto and recursion. All loops must have fixed bounds. This prevents runaway code. Avoid heap memory allocation after initialization. Restrict functions to a single printed page. Use a minimum of two runtime assertions per function. Restrict the scope of data to the smallest possible.
iptables is a user-space utility program that allows a system administrator to configure the IP packet filter rules of the Linux kernel firewall, implemented as different Netfilter modules. The filters are organized in a set of tables, which contain chains of rules for how to treat network traffic packets.
