10This rule detects when a new GitHub App has been installed in your organization account. GitHub Apps extend GitHub's
11functionality both within and outside of GitHub. When an app is installed it is granted permissions to read or modify
12your repository and organization data. Only trusted apps should be installed and any newly installed apps should be
13investigated to verify their legitimacy. Unauthorized app installation could lower your organization's security posture
14and leave you exposed for future attacks.
