Abstract

The IBM System i family, with its operating system IBM i5/OS, is considered one of the most secure systems in the industry. From the beginning, security was designed as an integral part of the system. The System i platform provides a rich set of security features and services that pertain to the goals of authentication, authorization, integrity, confidentiality, and auditing. However, if an IBM Client does not know that a service, such as a virtual private network (VPN) or hardware cryptographic support, exists on the system, they will not use it.

In addition, there are more and more security auditors and consultants who are in charge of implementing corporate security policies in an organization. In many cases, they are not familiar with the System i platform, but need to understand the security services that are available.

This IBM Redbooks publication guides you through the native security features that are available on the System i platform. This book is intended for security auditors and consultants, IBM System Specialists, Business Partners, and Clients to help you answer first-level questions concerning the security features that are available on the System i platform.
