Stranger Danger - Finding vulnerabilities before they find you - Liran Tal 2021
0 likes38 views
The document discusses finding security vulnerabilities in open source software before attackers can exploit them. It notes that open source packages often have dependencies with vulnerabilities and that vulnerabilities in popular packages can affect many users. It advocates for making security easier and more developer-friendly to integrate into the development process. It also provides best practices for open source maintainers such as having a responsible disclosure policy, scanning for vulnerabilities, and promptly releasing security fixes.
