Most security books are targeted at security engineers and specialists. Few show how build security into software. None breakdown the different concerns facing security at different levels of the system: the enterprise, architectural and operational layers. This book addresses the full engineering spectrum. It extends to the larger enterprise context and shows engineers how to integrate security in the broader engineering process. · The Pattern Approach · Security Foundations · Security Patterns · Patterns Scope and Enterprise Security · The Security Pattern Landscape · Enterprise Security and Risk Management · Identification and Authentication (I&A) · Access Control Models · System Access Control Architecture · Operating System Access Control · Accounting · Firewall Architectures · Secure Internet Applications · Case Study: IP Telephony · Supplementary Concepts · Closing Remarks
