We Hold These Truths to be Self-evident Software security is more than a set of security functions o Not magic crypto fairy dust o Not silver-bullet security mechanisms Non-functional aspects of design are essential Bugs and flaws are 50/50 Security is an emergent property of the entire system (just like quality) To end up with secure software, deep integration with the SDLC is necessary

Prescriptive vs. Descriptive Models Descriptive models describe what is actually happening The BSIMM is a descriptive model that can be used to measure any number of prescriptive SSDLs Prescriptive Models Descriptive Models Prescriptive models describe what you should do SAFECode SAMM SDL Touchpoints Every firm has a methodology they follow (often a hybrid) You need an SSDL

Building BSIMM (2009) Big idea: Build a maturity model from actual data gathered from 9 well known large-scale software security initiatives o Create a software security framework o Interview nine firms in-person o Discover 110 activities through observation o Organize the activities in 3 levels o Build scorecard The model has been validated with data from 67 firms There is no special snowflake

10. Copyright © 2013, Cigital and/or its affiliates. All rights reserved. The Magic 30 Since we have data from > 30 firms we can perform statistical analysis (Laurie Williams from NCSU is doing more of that now) o How good is the model? o What activities correlate with what other activities? o Do high maturity firms look the same? We now have 67 firms with 161 distinct measurements o BSIMM (the nine) o BSIMM Europe (nine in EU) o BSIMM2 (30) o BSIMM3 (42) o BSIMM4 (51) o BSIMM-V (67) ← data freshness emphasized

13. Copyright © 2013, Cigital and/or its affiliates. All rights reserved. Example Activity [AA1.2] Perform design review for high-risk applications. The organization learns about the benefits of architecture analysis by seeing real results for a few high-risk, high- profile applications. The reviewers must have some experience performing architecture analysis and breaking the architecture being considered. If the SSG is not yet equipped to perform an in-depth architecture analysis, it uses consultants to do this work. Ad hoc review paradigms that rely heavily on expertise may be used here, though in the long run they do not scale.

14. Copyright © 2013, Cigital and/or its affiliates. All rights reserved. NEW BSIMM-V Activity [CMVM3.4] Operate a bug bounty program. The organization solicits vulnerability reports from external researchers and pays a bounty for each verified and accepted vulnerability received. Payouts typically follow a sliding scale linked to multiple factors, such as vulnerability type (e.g., remote code execution is worth $10,000 versus CSRF is worth $750), exploitability (demonstrable exploits command much higher payouts), or specific services and software versions (widely- deployed or critical services warrant higher payouts). Ad hoc or short-duration activities, such as capture-the-flag contests, do not count. [This is a new activity that will be reported on in BSIMM6.]
