5 IAS/Principles of Secure Design
(RIF Bishop cap. 13)
Least privilege and isolation, Fail-safe defaults, Open design, End-to-end security, Defense in depth (e.g., defensive programming, layered defense), Security by design, Tensions between security and other design goals, Complete mediation, Use of vetted security components, Economy of mechanism (reducing trusted computing base, minimize attack surface), Usable security , Security composability Prevention, detection, and deterrence
6 IAS/Defensive Programming
Input validation and data sanitization, Choice of programming language and type-safe languages, Examples of input validation and data sanitization errors
Buffer overflows documentazione di riferimento
Integer errors
SQL Injection, documentazione di riferimento
XSS vulnerability, documentazione di riferimento
Race conditions
Correct handling of exceptions and unexpected behaviors
Correct usage of third-party components
Effectively deploying security updates
7 IAS/Threats and Attacks
