Website Security

ACS

CSP is not implemented

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

HttpOnly cookies used

Using HttpOnly cookies reduces the risk of client side script attacks, by preventing cookies being read on the client.

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.

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.

Email

ACS

DMARC policy is p=quarantine

The DMARC policy should be set to p=reject for maximum protection.

DMARC policy exists

DMARC protects against fraudulent emails being sent from a domain.

Strict SPF filtering - not using +all

Sender Policy Framework (SPF) record strictly enforces specific domains allowed to send email on its behalf.

SPF syntax correct

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

DMARC policy percentage is default

DMARC policy percentage is set to default 100%, ensuring all mail is covered by the policy.

SPF ptr mechanism not used

Sender Policy Framework (SPF) record does not include the ptr mechanism.

See details

Network

ACS

'HTTP' port open

The 'HTTP' service is running and exposed to the internet. The configuration of the server should be reviewed and unnecessary ports closed.

See details

DNS

ACS

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.

See details

Encryption

ACS

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.

HTTPS redirect not supported

HTTPS is the standard protocol for secure communication on the internet. All redirects should be performed over HTTPS.

Domain was not found on the HSTS preload list

The domain was not found on the HSTS preload list. Users who visit the website for the first time will be vulnerable to MITM attacks. The requirements for inclusion on the preload list are specified by hstspreload.org.

HSTS header does not contain includeSubDomains

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.

SSL available

SSL is supported for this site.

HTTP requests are redirected to HTTPS

All HTTP requests are redirected to HTTPS.

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.

SSL has more than 20% of its valid period remaining

SSL certificate does not expire in less than 20% of its total valid period.

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.

Data leakage

ACS

No open cloud storage service detected

No cloud storage service configured to allow anonymous file listing was detected.

Domain index is not a listable directory

The domain index is not a listable directory.

Vulnerability Management

ACS

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.
