The blog post is the first in a series focused on enhancing the security of the Exiv2 project, a command-line utility and C++ library for reading or modifying image file metadata. The author, Kevin Backhouse, shares his approach to hardening project security by detailing the creation of a security advisory process using GitHub's SECURITY.md, security advisories, and CVE requests. He highlights the importance of clear communication in security processes and emphasizes the use of GitHub's security features for private discussions and vulnerability management. The post reflects on the author's dual role in security, balancing offensive and defensive tasks, and aims to provide insights and practical examples to help others secure their projects. The series will continue with discussions on bug fixing, CodeQL queries, and fuzzing techniques.
