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