Is SELinux a firewall?

Though often confused with one, SELinux is not a firewall. A firewall controls the flow of traffic to and from a computer to the network. SELinux can confine access of programs within a computer and hence can be conceptually thought of a internal firewall between programs. Security works best when multiple layers are used and SELinux is complimentary to a firewall and other security features.
