6 security settings every GitHub maintainer should enable this week

GitHub published a post recommending six free security settings that maintainers can enable to harden their projects against common attacks. According to the blog, these measures won't make a project unhackable, but they will close obvious vulnerabilities that attackers often exploit. The settings include enabling branch protection rules, requiring signed commits, configuring secret scanning, and other options available in repository settings. The article emphasizes that these are low-effort, high-impact changes suitable for any public or private repository. For developers building AI workflows, where projects often rely on multiple dependencies and automated pipelines, these settings help prevent supply-chain attacks and unauthorized code changes. The post serves as a practical reminder that security basics should not be overlooked, even when focusing on rapid development with AI tools.
