program (or the system) to observe the reported symptoms • Developing new / updating existing test assets to demonstrate the failure • Pro tip: Make sure you're looking at the correct source code! • Characterizing Techniques Copyright © 2021 Bob Steagall Understand the Problem • Inspect and verify the associated test assets • The test case(s) or harness(es) may be broken • If appropriate, test data should demonstrate incremental, bottom-up development • Add functionality in small sections of code • Create test assets for each new increment of functionality • Verify that new code doesn't cause previous test cases

binary cache 3. Version using baselines 4. Build open-source with a package manager 5. Cache build assets internally 6. Monitor, prevent, and respond to vulnerabilities 7. Centralize common tasks 8. Produce be a network outageProblem 5: Organization restricts access to online downloads Solution 5: Cache assets needed for builds •Companies must maintain their own internally-controlled copies of any software everything you need once outside of your “controlled” environment. • Verify that all downloaded assets are valid and compliant with your org’s rules. • Move cache to shared location accessible to all
