PCI DSS Compliance and System z – A Combination That Makes Sense
"It is not enough to be honest – you must also protect your assets and your customers from those who are not...This means that enterprise IT systems are no longer primarily IT systems. They are primarily business systems – and, in business, security cannot be a haphazard after thought." — Anne MacFarland, analyst for The Clipper Group.

IBM System z Security Covers the Enterprise End to End by Anne MacFarland, The Clipper Group
The more the mainframe secures, the better the security across the enterprise. To be effective, security must match the scope of enterprise business processes, yet not impar process efficiency. What is needed is an integrated security solution - with the ability to spread, where needed - to secure business processes and business information; this is an attractive and much saner proposition. The mainframe has been working in this mode and meeting such challenges for a long time. System z offers well-honed and time-tested capabilities that help you achieve security, corporate governance, and regulatory compliance without changing how you do business.

IBM Tivoli Storage Manager Building a Secure Environment
Many people want to be famous, but nobody wants to hit the headlines in an incident resulting in the theft or misuse of their employees' or clients' confidential data. While the necessity of securing the confidentiality, integrity, and availability of the enterprise's servers and data is well known, the backup server is often overlooked in the security planning process. This redbook will take you through the various security features of Tivoli Storage Manager, and show you how to use them, together with best practice principles, to design, implement, and administer a more secure backup management environment. We will cover passwords, administrative levels of control, the vital role of encryption, and procedures for managing offsite data, among other topics.

Introduction to the New Mainframe: Large-Scale Commercial Computing
Today, mainframe computers play a central role in the daily operations of most of the world's largest corporations. The mainframe occupies a prominent place in today's e-business environment. In banking, finance, health care, insurance, utilities, government, and a multitude of other public and private enterprises, the mainframe computer continues to provide the foundation of large-scale computing to modern business.
The reasons for mainframe use generally fall into one or more of the following categories: capacity, scalability, integrity and security, availability, access to large amounts of data, system management, and autonomic capabilities. This IBM Redbook is designed for readers who already possess a basic knowledge of mainframe computing, but need a clearer understanding of how these concepts relate to mainframe planning, implementation, and operation.

Federated Identity Management Solutions
Federated Identity Management (FIM for z/OS) provides a simple, loosely coupled model for managing identity and access to resources that span companies or security domains. Rather than replicate identity and security administration at both companies, FIM for z/OS provides a simple model for managing identities and providing them with access to information and services in a trusted fashion. For companies deploying Service Oriented Architecture (SOA) and Web Services, FIM for z/OS provides policy-based integrated security management for federated web services. The foundation of FIM for z/OS is trust, integrity, and privacy of data.
