Website Security

tlmetal

Server information header exposed

Exposing information about the server version increases the ability of attackers to exploit certain vulnerabilities. The website configuration should be changed to prevent version information being revealed in the 'server' header.

X-Frame-Options is not deny or sameorigin

Browsers may display this website's content in frames. This can lead to clickjacking attacks.

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.

CSP is not implemented

No valid Content Security Policy is implemented. This increases the risk of XSS and clickjacking attacks.

CSP contains unsafe-eval

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

X-Content-Type-Options is not nosniff

Browsers may interpret files as a different MIME type than what is specified in the Content-Type HTTP header. This can lead to MIME confusion attacks.

Unmaintained page detected

This domain appears to be unmaintained based on indicators like page content or status code. Unmaintained pages expand the attack surface for malicious actors.

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.

Email

tlmetal

DMARC policy not found

DMARC policy was not found. This makes it easier for attackers to send email from this domain. A DMARC policy should be deployed for this domain.

SPF policy uses ~all

Sender Policy Framework (SPF) record is too lenient as to which domains are allowed to send email on the domain's behalf. This record should preferably not use the ~all mechanism, as this does not instruct the mail receiver to reject messages from unauthorised sources. When DMARC is not being enforced, -all should be used on the SPF record.

SPF ptr mechanism used

Sender Policy Framework (SPF) record contains the ptr mechanism. This mechanism is intended to be used temporarily to check that a domain resolves to itself via a known IP address. This should not be used permanently as it puts unnecessary burden on DNS servers and some mail checkers may drop the SPF record if this mechanism is found.

SPF enabled

Sender Policy Framework (SPF) records prevent spammers from sending messages with forged addresses.

SPF syntax correct

Sender Policy Framework (SPF) record passes basic syntax checks.

DNS

tlmetal

DNSSEC not enabled

DNSSEC records prevent third parties from forging the records that guarantee a domain's identity. DNSSEC should be configured for this domain.

CAA not enabled

The domain does not contain a valid Certification Authority Authorization (CAA) record. A CAA record indicates which Certificate Authorities (CAs) are authorized to issue certificates for a domain.

No unregistered MX records detected

No unregistered MX records that could lead to receiving mail on behalf of the target organization were detected.

No subdomain takeover vulnerability detected

No dangling DNS records that could lead to subdomain takeover were detected.

Encryption

tlmetal

SSL not available

SSL is the standard encryption method for browsing websites. Enabling SSL requires installing an SSL certificate on the site.

HTTP does not redirect to HTTPS

The domain is still accessible over HTTP. All HTTP requests should be redirected to HTTPS.

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.

SSL expires in less than 20% of its total valid period

SSL certificate has less than 20% of its total valid period remaining. The certificate will need to be renewed to avoid expiry.

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

SSL certificate has not expired.

Trusted SSL certificate

The certificate presented by this domain was issued by a trusted certificate authority.

No insecure SSL/TLS versions available

No insecure SSL/TLS versions are available for this site.

SSL certificate chain present in server response

A complete SSL certificate chain was presented by the server for this domain.

SSL chain certificates do not expire within 20 days

SSL intermediate and root certificates do not expire within 20 days.

SSL expiration period shorter than 398 days

The SSL certificate presented by the server has an expiration period shorter than 398 days.

Strong SSL algorithm

Industry standard SHA-256 encryption in use.

Strong public certificate key length

The site's public certificate provides at least 112 bits of security strength.

Vulnerability Management

tlmetal

Not vulnerable to CVE-2014-0160 (Heartbleed)

A bug in OpenSSL's implementation of the TLS heartbeat extension allows access to portions of memory on the targeted host e.g. cryptographic keys and passwords.

Not vulnerable to CVE-2014-3566 (POODLE)

The server does not support SSLv3, and is not vulnerable to the POODLE attack.

Not vulnerable to CVE-2015-0204 (FREAK)

The server does not offer RSA_EXPORT cipher suites, so clients are not vulnerable to the FREAK attack.

Not vulnerable to CVE-2015-4000 (Logjam)

The server is using strong Diffie-Hellman parameters and is not vulnerable to the Logjam attack.
