Website Security

ADT

CSP implemented unsafely

The Content Security Policy may not restrict sources appropriately, or may contain 'unsafe-inline' without the use of a nonce or hash. This increases the risk of XSS attacks.

HttpOnly cookies not used

When HttpOnly cookies are not used, the cookies can be accessed on the client, which enables certain type of client-side attacks. The website configuration should be changed to enforce HttpOnly cookies.

CSP contains unsafe-eval

The Content Security Policy is implemented with unsafe-eval, reducing protection against XSS attacks.

Secure cookies used

Using secure cookies reduces the risk of third parties intercepting information contained in these cookies.

Server information header not exposed

Ensuring the server information header is not exposed reduces the ability of attackers to exploit certain vulnerabilities.

X-Powered-By header not exposed

Information about specific technology used on the server is obscured.

CSP implemented without insecure active sources

The Content Security Policy does not allow any insecure active sources.

Referrer policy is not unsafe-url

The website's Referrer Policy is not configured to allow unsafe information to be sent in the referrer header.

ASP.NET version header not exposing specific ASP.net version

Ensuring the ASP.NET version header is not exposing a specific version makes it harder for attackers to exploit certain vulnerabilities.

ASP.NET version header not exposed

Ensuring the ASP.NET version header is not exposed makes it harder for attackers to exploit certain vulnerabilities.

CSP implemented without insecure passive sources

The Content Security Policy does not allow any insecure passive (img/media) sources.

X-Content-Type-Options is not nosniff

Browsers are prevented from interpreting files as a different MIME type to what is specified in the Content-Type HTTP header. This helps mitigate MIME confusion attacks.

No unmaintained page detected

The page appears to be maintained.
