AIX Version 6.1 provides many significant new security technologies and security enhancements. The purpose of this IBM Redbooks publication is to highlight and explain the security features at the conceptual level, as well as provide practical examples of how they may be implemented. Some features are extensions of features made available in prior AIX releases, and some are new features introduced with AIX V6. Major new security enhancements will be introduced with AIX V6 in 2007: - Trusted AIX (Multilevel Security) - Role Based Access Control (RBAC) - Encrypted File System - Trusted Execution - AIX Security Expert Enhancements This IBM Redbooks publication will provide a technical introduction to these new enhancements. The topics are both broad and very complex. This book will serve as an initial effort in describing all of the enhancements together in a single volume to the security/system hardening oriented audience.

This IBM Red paper books publication presents Workload Partitions (WPARs), a set of completely new software-based system virtualization features introduced in IBM AIX Version 6.1. Adding WPARs to the AIX operating system provides a new level of system virtualization capability. WPARs complement the already existing AIX and System p virtualization features, by allowing: - The partitioning of an AIX instance into multiple environments, each hosting applications and providing isolation from applications executing in the other environments - The ability to checkpoint and restart execution of applications without modification of the application code - The capability to relocate a live application into a different AIX instance, whether it is hosted in an LPAR of the same physical server or executing on a different physical server - Fine-grained control of resource utilization by each application executing within an AIX instance

Workload partition functionality, originally introduced in 2007 with the release of IBM AIX Version 6, is a strategic component of the IBM AIX Operating System. With the release of AIX V6.1 TL2 in November 2008, both the core functionality and features related to managing workload partitions have been improved and expanded. This IBM Redbooks publication provides an updated introduction and "how to" guide for system administrators and architects using workload partitions in AIX V6.1 TL2. It builds on the original concepts and practices described in the first Redbooks publication about this topic, Introduction to Workload Partition Management in IBM AIX Version 6.1, SG24-7431 , published in 2007. In AIX 6.2 TL2, significant enhancements to core workload partition functions and new features have been added. Some of the important feature updates provide more flexibility and support for enhanced mobility, improved isolation, and NIM integration. A new and significantly updated version of IBM Workload Partitions Manager for AIX (WPAR Manager), the Web browser-based graphical user interface for managing and monitoring WPARs, is also available. WPAR Manager is a platform management solution that provides a centralized point of control for managing WPARs across a collection of managed systems running AIX.

NFS Version 4 (NFS V4) is the latest defined client-to-server protocol for NFS. A significant upgrade from NFS V3, it was defined under the IETF framework by many contributors. NFS V4 introduces major changes to the way NFS has been implemented and used before now, including stronger security, wide area network sharing, and broader platform adaptability. This IBM Redbooks publication is intended to provide a broad understanding of NFS V4 and specific AIX NFS V4 implementation details. It discusses considerations for deployment of NFS V4, with a focus on exploiting the stronger security features of the new protocol. In the initial implementation of NFS V4 in AIX 5.3, the most important functional differences are related to security. Chapter 3 and parts of the planning and implementation chapters in Part 2 cover this topic in detail.

The aim of this IBM Redbooks publication is to provide a technical reference for IT system administrators in organizations that are considering a migration from Sun Solaris to IBM AIX 5L-based systems. This book presents a system administrator view of the technical differences that exist and the methods that are necessary to complete a successful migration to AIX 5L-based systems. This book is designed primarily as a reference for experienced Sun Solaris 8 or 9 system administrators who will be working with AIX 5L. This book is not an AIX 5L administration how-to book for system administrators who are beginners, but rather a guide for experienced administrators who have to translate a given Solaris system administration task to AIX 5L.
