QUESTION: 5

Jim’s organization has just completed a major Linux roll out and now all of the organization’s systems are running the Linux 2.5 kernel. The roll out expenses has posed constraints on purchasing other essential security equipment and software. The organization requires an option to control network traffic and also perform stateful inspection of traffic going into and out of the DMZ.
Which built-in functionality of Linux can achieve this?

IP Tables
IP Chains
IP Sniffer
IP ICMP

Answer(s): A

Explanation:

iptables is a user space application program that allows a system administrator to configure the netfilter tables, chains, and rules (described above). Because iptables requires elevated privileges to operate, it must be executed by user root, otherwise it fails to function. On most Linux systems, iptables is installed as /sbin/iptables. IP Tables performs stateful inspection while the older IP Chains only performs stateless inspection.
