Content Security Policy Hidden Benefits
Can CSP really keep my website safe?
Yes, it is true, by enabling Content Security Policy (CSP) your website will add a security layer that would help prevent Cross Site Scripting (XSS) and data injection attacks. This also has lots of hidden perks that your company could benefit from.
Reliable browsers are just like banks when you buy a property. If you apply to take out a loan to buy a house, the bank is responsible for analysing the house, establishing the real market price and investigating the seller or the constructor to make sure it’s a safe deal. Only then, after everything is fine, the loan will be granted.
“Aww! The bank cares about me!” You might be thinking. However, be mindful that the bank is only looking out for their own interests. Basically, in the event you can't pay your loan, the bank will get to own your house. As such, their mission is to avoid owning a property that has a lower value than the actual market price so they can eventually sell it and recover their investment.
Similarly, browsers and CSP properly enable work for you. They help your website and your company stay out of trouble. Here are a few ways CSP can help you:
You could discover that a service you explicitly disabled from tracking actually sends the data to a 4th party. This may or may not track your users’ activity, violating your website’s GDPR Policy without your knowledge and without your users’ actual consent. As such, CSP can act like a GDPR audit for the front end of your website.
Another big benefit is that you will get familiarized with all the scripts your website uses to communicate with other hosts. This will help you paint a clearer picture of what scripts to remove, what scripts to trust and you will know exactly which ones will face some restrictions in order for your company to be safe when it comes to these new regulations.
If you consider using CSP for your website, I applaud your decision. However, be prepared to change a few habits that you would have never considered harmful before. Be prepared to decide which of your website’s third party code snippets will get whitelisted, will change functionality in order to become compliant or simply go away.
