Website Security

SEB

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.

X-Frame-Options is not deny or sameorigin

Browsers are prevented from displaying this website's content in frames. This helps mitigate clickjacking attacks.

CSP implemented without insecure active sources

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

CSP implemented without broad sources

A Content Security Policy is implemented to help protect against XSS and clickjacking attacks.

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.

Encryption

SEB

HTTP Strict Transport Security (HSTS) not enforced

Without HSTS enforced, people browsing this site are more susceptible to man-in-the-middle attacks. The server should be configured to support HSTS.

Domain was not found on the HSTS preload list

The HTTP Strict Transport Security (HSTS) header does not contain the includeSubDomains directive. This directive instructs the browser to also enforce the HSTS policy over subdomains of this domain.

Weak cipher suites supported in TLS 1.2

Weak cipher suites can potentially be broken by a well resourced attacker, and should not be supported by the server unless very old devices or browsers must be supported.

Certificate not found on our revoked certificate list

The site's certificate chain was checked against our list of revoked certificates.

Hostname matches SSL certificate

The site's hostname matches the SSL certificate.

SSL has not expired
