Website Security

Sunelec

Secure cookies not used

When secure cookies are not used, there is an increased risk of third parties intercepting information contained in these cookies. The website configuration should be changed so that all 'Set-Cookie' headers include 'secure'.

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-Powered-By header exposed

The X-Powered-By header reveals information about specific technology used on the server. This information can be used to exploit vulnerabilities. The server configuration should be changed to remove this 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 is not implemented

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

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.

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.

Email

Sunelec

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 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.

SPF ptr mechanism not used

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

DNS

Sunelec

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

Sunelec

HTTPS is redirected to an insecure protocol

HTTPS is redirected to an insecure protocol. HTTPS requests should not be redirected to insecure protocols, as they do not ensure encrypted communication between the website and its visitors.

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.

Insecure SSL/TLS versions available

Any version of the SSL protocol, and TLS prior to version 1.2, are now considered insecure. The server should disable support for these old protocols.

Insecure cipher suite supported

Insecure cipher suites can be trivially broken by an attacker, allowing them to impersonate your server or eavesdrop on traffic.

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
