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

中国建筑网 is a Chinese online education platform specializing in providing comprehensive information and resources for construction and engineering certification exams, including 二级建造师 (Second-level Constructor) and related professional certifications. The platform offers exam schedules, registration details, study materials, mock tests, and results inquiry services, targeting construction professionals and exam candidates in China. The website is well-structured with a clear focus on educational content and exam preparation, serving a niche but important market segment within the education sector. Technically, the website employs standard web technologies such as jQuery and Bootstrap, ensuring moderate performance and good mobile responsiveness. However, the site lacks advanced security configurations like DNSSEC and security headers, which could be improved to enhance its security posture. The domain is newly registered in mid-2024, which may indicate a recent launch or rebranding, although the business claims a founding year of 2018. From a security perspective, the site uses HTTPS URLs but does not show evidence of robust security headers or published security policies. No privacy or cookie policies are present, which is a compliance gap, especially for GDPR or similar regulations. Contact information is limited to phone numbers and a search form, with no email or social media presence detected. No incident response or vulnerability disclosure mechanisms are published, which could be a risk factor. Overall, the website is functional and serves its educational purpose well but would benefit from enhanced security measures, privacy compliance documentation, and clearer contact channels to improve trust and regulatory adherence.

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

8 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. 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

  3. 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';…

  4. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

Results by check

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 platform positions itself as a specialized education service provider in the construction certification niche in China, focusing on exam-related content and services. Its business model revolves around content provision and possibly advertising or partnerships with related educational entities. The site links to multiple regional and industry-related domains, indicating a network of partnerships or resource sharing. The lack of direct e-commerce or payment processing suggests a content-driven revenue model. Growth potential exists in expanding digital services, certifications, and user engagement tools. The new domain registration suggests recent strategic initiatives or expansion. The platform's competitive advantage lies in its comprehensive and updated exam information and resources tailored for Chinese construction professionals.

Security posture

The current security posture is basic with HTTPS usage but lacks DNSSEC and critical security headers such as Content-Security-Policy or X-Frame-Options. No privacy or cookie policies are published, indicating compliance gaps. The absence of incident response contacts or vulnerability disclosure channels reduces transparency and readiness for security incidents. No evidence of vulnerable libraries was found, but the use of older jQuery versions could pose risks if not updated. The domain is locked against transfer, which is a positive control. Overall, the site should prioritize implementing security headers, enabling DNSSEC, publishing privacy and cookie policies, and establishing clear security contact points to improve its security maturity.

Recommendations

  1. Implement and enable DNSSEC to secure DNS resolution and prevent spoofing.
  2. Add essential security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish comprehensive privacy and cookie policies to improve compliance and user trust.
  4. Establish and publicize incident response and vulnerability disclosure contacts or pages.
  5. Regularly update JavaScript libraries and dependencies to mitigate known vulnerabilities.

Technical notes

Notes

The website uses a traditional web stack with jQuery and Bootstrap for UI and interactivity. The HTML structure is valid and includes responsive design elements for mobile optimization. Performance is moderate with no major blocking scripts detected. SEO is supported by meta keywords and description tags in Chinese. However, the site lacks modern CMS indicators and advanced analytics or marketing tools. Hosting details are limited to registrar information, with no explicit CDN or cloud hosting detected. The site could benefit from modernization efforts including improved accessibility features and enhanced performance optimizations.
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.
