In this post I'll show you how I created a new, better, CSP policy from scratch. I'm going to assume some familiarity with the fundamentals of CSP. For a good introduction on CSP and the motivations behind it, read this article.

CSP follows a whitelist model. If you include the header but don't include a specific directive, that is equivalent to specifying * as the valid source for that directive (i.e. everywhere). hooded rat plushOn the other hand, if you do include a directive, only the sources listed will be allowed.imking hoodies There are a lot of directives that can be used to enforce policies for content types. assassins hoodies czYou can see an exhaustive list of directives here. hoody kim wikiCSP also allows policies around particular circumstances, such as whether the browser should include referer headers when following links away from a page.mc5 hoodie

A good start for any CSP policy is the directive default-src 'none'. This directive does what you'd expect it to do: if a directive isn't explicitly set, it will default to this value.nike fanatic hoodie opinie Unfortunately, the directives in the following list don't use default-src as a fallback, which means that we will have to remember to set them explicitly, or they will default to allowing everything. First, we will start by allowing the current origin (self) to load most resource types. Second, we're going to instruct the browser to block mixed content, explicitly enable reflected XSS protections, ensure we're not sending referrer headers when downgrading from HTTPS to HTTP (to avoid referrer leaks), and access every HTTP URL via HTTPS instead. Note that, by leaving connect-src, media-src, object-src, and child-src out of this policy, we're effectively disallowing XMLHttpRequest, WebSockets, audio, video, Flash, and iframes from being used with this website.

Even though generating CSP policies manually is incredibly instructive, it is also very typo prone. Feel free to use a CSP headers generator to generate your base policy instead. At this point we have a strong initial policy that will not allow loading anything external to your own domain. Instead of deploying it in enforce mode, which would most likely break your website, we can swap out Content-Security-Policy for Content-Security-Policy-Report-Only, and get a comprehensive list of everything that doesn't follow this base policy. This is a good way of finding the minimum set of necessary resources that we need to allow to enable enforce mode. Some common exceptions you may have to add are going to be external resources, such as javascript, images and fonts. For example, in order to allow the embedding of slideshare decks (see image above), I added the following directive: To allow loading google fonts and google analytics, I added: Note the change to img-src directive.

Google analytics uses a tracking pixel, which is technically an image. One of the reasons why CSP is such a big deal for web security is the fact that it can largely eliminate XSS attacks. It does so by not allowing inline script tags and javascript:// URLs. Unfortunately, developers use a lot of inline code. This is actually one of the most common roadblocks to creating a good CSP policy. There is a directive value that was created specifically to work around this issue: unsafe-inline, but you should never use it. Instead, you should turn your inline javascript into an externally loaded script. One of the coolest directives of CSP is report-uri, which specifies the URL to which browsers should report violations of the Content Security Policy. You can deploy your own application to receive these reports, or use a free online version, like report-uri.io. , and added the following line to my policy:This is what a violation would look like: Remember the earlier directives that don't inherit the default behavior?

Well, we should explicitly set those to some reasonable values. This is my final policy: At this point we can use the online CSP analyzer, to make sure we're green across the board. Unfortunately, HTTP headers aren't compressed, which means that you will be injecting a potentially large CSP header into every HTTP response. To avoid that, you can set some or all of your policies directly in the page markup. You do that by using the meta tag with an http-equiv attribute: There are three directives that can’t be set using meta tags: frame-ancestors, report-uri, and sandbox. Another possible work-around is to take advantage of the conditional header injection features of your web server. If you're using nginx, you can create a map that will return different headers, based on the content-type of the page. By designing your CSP policies from scratch, you can achieve a least-privilege CSP deployment, and create a policy that allows exactly what you need. No more, no less.
