The Trustworthy Information Systems Handbook was last modified in 2002.  While the concepts and ideas documented in the Handbook about what makes up a Trustworthy Information System have not changed much over time, there are more recent tools that can be used in exploring your options.  Two such resources are the Trusted Repository Audit Checklist (TRAC) and the Digital Repository Audit Method Based on Risk Assessment (DRAMBORA).
