- XKCD – reinvent the wheel – “We don’t want to reinvent the wheel, so every day we google image search “wheel” and whatever object comes up, that’s what we attach to our vehicles. Sure external dependencies carry risks, but so far, they’ve all been pretty good wheels”
- If just moving fast, have a problem
- DevOps teams use more open source
- 70% deploy at least once a week
- Challenge: be faster than evil
- In past 5 years, breaches increased 70%
- Can’t predict when vulnerability will come up. Have to use without knowing what will happen.
- Equifax is old news by now. Had opportunity to patch
- Adversaries can also contribute to open source. ex: npm event-stream attack on CoPay
- 2019 – Gems bootstrap-saas – added backdoor
- Typo squatting
- Happening to Docker, Python, Ruby, NPM, etc
- 2019 Software Supply Chain Report
- suppliers (open source)
- warehouses, (component repos)
- manufacturers (softare dev teams)
- finished goods (software applications)
- Maven Central had over 200B downloads in 2019 alone. Almost 10% had known vulnerabilities they day they were downloaded.
- 85% of app is sourced from external suppliers
Enterprise vs Open Source
- Multiple deploys per day vs versioned releases
- Consistent Dev team vs fluid group of developers
- Predictable/well resources vs variable resources
- Deploymen tvs release frequency
- Organizational performance vs popularity
- Mean time to restore vs time to remediate vulnerabilities
Is it true?
- TRUE: Projects that release frequently have better outcomes – more popular, attack more developers and higher level of support from foundations. Also, avoids problem of having to wait for all the transitive dependencies to be in a version we are using.
- TRUE: Projects that update dependencies more frequently are general more secure
- FALSE: Projects with fewer dependencies will stay more up to date. Interestingly, smaller teams tend to have less dependencies. Not clear if correlation or causationl
- FALSE: More popular projects will be better about staying up to date
- Small teams; excellent time to update
- Large teams; excellent time to update, often foundation supported, popular
- Laggards – release slowly, more likely to be commercially supported
- Features first – release frequently, but poor time to update
- Caution – good time to update, but seldom completely up to date
- 38% schedule dependency updates
- 46% strive to use latest version
- 50% have process to add new dependency
- 30% have process to proactively remove problematic or unused dependency
- 37% have automated tool to track, managed and/or ensure policy compliance of dependencies
If only do one thing
- If stay on latest version, by default more secure and less security issues.
Good talk. Especially once the projector issues were fixed. I lik the graphs and data behind the main points. I’ve seen similar presentations, but the newer parts/stats were still good to hear.
