SeaSP Community Edition


Sea SP-Community Edition is an automated Content Security Policy manger that first installs a strict non-blocking CSP to collect violation data.
Once violation data is collected it is stored in the WordPress database as a php object in the plugin options schema.
Sea SP-Community Edition then allows you to look through each of the violations and approve domains for each directive that has been violated.
One can choose to either approve the base domain or subdomains or both.
Other features include the ability to set sources of content for each directive of the CSP such as only allowing HTTP or HTTPS domains or Allowing inline scripts only for style sources.
The UI gives the user tips on what each directive does and how it should be used to protect their site.
Once domain and directive settings are done being configured the CSP can then be turned to blocking mode to protect the site


Once installed a strict non-blocking CSP is implemented on your site visit each page of your site to collect CSP violations for each of those pages.
Visit the Current Violations page of the plugin to review domains that have violated a directive in the CSP.
Review each of the domains carefully and check for misspellings of common domains like instead of as this is a common way hackers inject content into your site.
If you feel confident that the domain belongs on your site and it should be serving the file type stated, click the toggle to approve the domain and include it in the CSP.
If you want to allow subdomains of that domain to be able to serve that type of content, click the include subdomains toggle.
To learn more about the directive that was violated click the blue Directive button.
After this process you might still see CSP violations regarding inline scripts, inline styles, blobs, or data.
To allow these this type of content in the community version you must navigate to the Directive Settings page, find the offending directive and toggle the appropriate option.
For convenience, each option has a tool tip explaining what it allows in your CSP.

A walk though of this plugin can be found here

= How does the plugin collect CSP violations? =

the plugin installs a small javascript in the head of your site that defines a variable named _BTT_CSP_FREE_ERROR the violations are then collected in this variable made into a json string and send to the back end of the plugin via ajax using a nonce. These errors are then parsed for the domains and the directives they have violated. This data is then stored as a php object in a plugin option. This data never leaves your site.

Best plugin when it comes to protecting and managing your content and it also collects the data of you site which violates certain things to help you to find and correct as soon as also auto mates mail processing making it easier for the user to manage...It also packed up with some ton of awesome feature in it. The way this plugins offers and care about user privacy and security is just worthy 👍Five stars from my side.
