  1. Running Static Analisys Tools Chapter 3

  2. Why Perform a code review? • Routinely (recommended)‏ • To prove a point. • To retrofit security into a project. • At least every release period, every project should receive a security review. At Microsoft, security reviews take about 20% of initial release time and 10% in subsequent iterations.

  3. The Review Cycle • Establish goals (subdivide up to, at most, program level)‏ • Run the static analysis tool (be sure the code compiles!)‏ • Review the code (using the output from the tool)‏ • Make fixes

  4. Some Gotchas • The Exploitability trap • Lame excuses (page 55)‏ • Adoption Anxiety. • Who runs the tool? • When is the tool run? • What happens to the results?

  5. Who runs the tool? • Canonical answers: • Programmers • Security • Better answer: • All of the above

  6. When is the tool run? • While the code is being written. • At build time • At major milestones

  7. What Happens to the results • Output feeds a Release Gate • A Central authority doles out individual results • A Central Authority sets Pinpoint Focus • Start Small, ratchet up.
