OWASP Security Principles
OWASP have a new Security Principles document available.
Inevitably applications are designed with security principles architects knew about, security folks included. However, as this project demonstrates there are far more than just a 'few' principles, most of which never make it into the design. For example, security design happens with perhaps a handful of principles: - least priviledge - perimiter security - defense in depth As a result, we regularly see designs without separation of privilege.
The principles and aphorisms cover reduction of surface area/attack vectors, reluctance to trust and a large collection of aphorisms (including Design for Failure, Orthogonal Security Mechanisms, Semantically consistent defence in depth and Use the Correct Algorithm And Correct Key Size).
