0–100, higher is better. How it is calculated

The website '2266自考网' serves as an educational portal dedicated to providing comprehensive resources and information related to self-study exams in China. It offers exam schedules, registration guidance, study materials, and news updates targeted primarily at Chinese students preparing for self-study higher education exams. The platform positions itself as a niche resource within the Chinese education sector, catering to a specialized audience seeking official and practical exam-related information. Technically, the website employs a traditional web stack including Bootstrap and an older version of jQuery, indicating a moderate level of digital maturity. The site is mobile responsive at a basic level and features a structured navigation system with regularly updated content. However, there is no evidence of advanced CMS usage or modern frameworks, and performance is moderate. SEO and accessibility practices are basic but functional. From a security perspective, the site uses HTTPS but lacks important security headers and DNSSEC, which are recommended for enhanced protection. The use of an outdated jQuery version may expose the site to known vulnerabilities. Privacy compliance is limited, with no cookie consent mechanism and only a basic privacy/terms page present. Contact information is minimal but available, enhancing business credibility somewhat. WHOIS data shows inconsistencies, particularly with domain creation dates and registrant information, which may warrant further investigation. Overall, the website is functional and serves its educational purpose well but would benefit from improved security practices, updated technical components, and enhanced privacy compliance to increase trust and resilience against threats.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

9 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  4. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet · found on this site
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The business operates as a specialized educational information provider focusing on self-study exams in China. Its competitive advantage lies in aggregating official exam schedules, policies, and study resources in one accessible platform. The business model appears to be content-driven, potentially monetized through partnerships or advertising, although no explicit monetization mechanisms are visible. The target customers are students and exam candidates seeking authoritative and updated exam information. The presence of multiple city-specific subdomains suggests a regionalized approach to content delivery. Partnerships with related educational and informational websites indicate an ecosystem strategy to broaden reach. Growth indicators include frequent content updates and a maintained ICP license. However, the lack of advanced digital marketing tools and limited contact channels may constrain expansion.

Security posture

The website demonstrates a basic security posture with HTTPS enabled, which is mandatory. However, the absence of DNSSEC and security headers such as Content-Security-Policy and X-Frame-Options reduces its defense-in-depth capabilities. The use of an outdated jQuery library introduces potential vulnerabilities that could be exploited. No incident response or security policy information is provided, indicating limited transparency and preparedness. Privacy compliance is weak, lacking cookie consent and GDPR indicators. The WHOIS data inconsistencies raise questions about domain legitimacy, which could impact trust. Overall, the security maturity is low to moderate, with significant room for improvement to meet modern standards and regulatory requirements.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement essential security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  3. Upgrade jQuery and other JavaScript libraries to their latest secure versions to mitigate known vulnerabilities.
  4. Introduce a cookie policy and consent mechanism to comply with privacy regulations and improve user trust.
  5. Clarify domain registration details and ensure WHOIS information aligns with business identity to enhance legitimacy.

Technical notes

Notes

The website is built using Bootstrap for responsive design and jQuery (version 1.x) for JavaScript functionality. The HTML structure is valid and includes meta tags for viewport and keywords, supporting basic SEO. The site loads external scripts from Baidu for link submission, indicating some SEO efforts. No modern CMS or structured data (JSON-LD/Open Graph) is detected, limiting rich search engine results. Mobile optimization is basic but present. Performance is moderate, with no explicit indicators of optimization or CDN usage. The hosting provider is not clearly identified beyond the registrar. The site uses multiple city subdomains to localize content. Overall, the technical infrastructure is functional but dated, with opportunities for modernization and performance enhancement.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
