Keep track of third-party scripts running on your websites.
Using third-party scripts means you trust that the script’s developer hasn’t inserted malicious functionality into the code and has secured it against attackers trying to do the same. Unfortunately, this isn’t always the case so third-party scripts can pose significant security risks.
People are changing what’s on the website. How can you be sure it’s secure if you don’t know what’s there?
Third-party risk management requires knowing what third-parties you manage. Website scripts often reference third-parties that have not been vetted.
Make sure that all third-party scripts are implemented securely via HTTPS.
Detect unexpected connections that can indicate data flowing to unapproved locations.
Identify scripts being hosted on domains that are no longer active that could potentially be taken over by a threat actor.
You can be alerted when the content of particular scripts change, and always see the full source and history of the script.
