Strengthening AIX Security: A System-Hardening Approach
AIX is an open UNIX operating environment that achieves increased levels of integration, flexibility and reliability—which means many of its services are immediately available when you finish installing the operating system. Without correct configuration, the system is vulnerable to several security exposures. This paper outlines the process of System Hardening, which uses minimization procedures to create a system with the fewest opportunities for exploitation. |
