Center for Internet Security benchmarks compliance for AIX 7.1

The Center for Internet Security (CIS) develops benchmarks for the secure configuration of a target system. CIS benchmarks are consensus-based, best-practice security configuration guides that are developed and accepted by government, business, industry, and academia.

The CIS Security Benchmark for AIX® 7.1 (https://www.cisecurity.org/benchmark/ibm_aix/) provides guidance for establishing a secure configuration for AIX version 7.1 running on IBM® Power® system servers. You can bring an AIX 6.1 or 7.1 system into compliance with the CIS Security Benchmark for AIX by applying the new profiles.
