TCP/IP security

If you installed the Transmission Control Protocol/Internet Protocol (TCP/IP) and Network File System (NFS) software, you can configure your system to communicate over a network.

This guide does not describe the basic concepts of TCP/IP, but rather describes security-related concerns of TCP/IP. For information on installing and the initial configuration of TCP/IP, refer to the Transmission Control Protocol/Internet Protocol section in Networks and communication management.

For any number of reasons, the person who administers your system might have to meet a certain level of security. For instance, the security level might be a matter of corporate policy. Or a system might need access to government systems and thus be required to communicate at a certain security level. These security standards might be applied to the network, the operating system, application software, even programs written by the person who administers your system.

This section describes the security features provided with TCP/IP, both in standard mode and as a secure system, and discusses some security considerations that are appropriate in a network environment.

After you install TCP/IP and NFS software, use the System Management Interface Tool (SMIT) tcpip fast path to configure your system.
