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

The website strm.co.kr represents CHANGJO LEISURE DEVELOPMENT LLC., a South Korean company operating premium family camping resorts under the brand '스테리움 캠핑 리조트'. The business focuses on providing camping, glamping, rental camping, caravan, and auto camping services primarily targeting families and outdoor enthusiasts in South Korea, with specific resort locations in Jecheon and Seocheon. The domain registration data aligns well with the business profile, showing a consistent South Korean registrant and appropriate domain age for a relatively new business established in 2021. Technically, the website employs a traditional tech stack including jQuery 1.11.1 and the Slider Revolution plugin for dynamic content presentation. The site is hosted likely via Gabia, a Korean registrar and hosting provider. The website design is professional and consistent, with good mobile optimization and basic SEO practices. However, the use of an outdated jQuery version and lack of visible security headers indicate areas for improvement in security posture. Security-wise, the site lacks explicit security headers and privacy or cookie policies, which are critical for compliance and user trust. No incident response or vulnerability disclosure information is present. The SSL configuration status is unknown from the data provided, but HTTPS is implied by the URL. No WAF or blocking mechanisms were detected, and no adult or questionable content is present, making the site safe for general audiences. Overall, the website presents a credible and professional business with moderate technical maturity. Strategic improvements in security headers, privacy compliance, and updating legacy libraries would enhance the security posture and trustworthiness. Adding clear privacy and cookie policies and incident response contacts would also improve regulatory compliance and user confidence.

Priority findings

11 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. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…

  3. 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
  • 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.

Business context

Business profile

CHANGJO LEISURE DEVELOPMENT LLC. operates in the hospitality sector, focusing on premium camping resorts in South Korea. Their business model centers on providing family-friendly outdoor leisure experiences through camping, glamping, and caravan rentals. The company targets domestic customers interested in nature and outdoor activities, leveraging locations in Jecheon and Seocheon to capture regional markets. The website's subdomains for each resort location indicate a segmented approach to marketing and service delivery. The partnership with Gabia for domain registration and hosting suggests reliance on local infrastructure providers. The absence of visible certifications or trust badges may indicate a small to medium-sized enterprise still building its brand credibility. The company appears to be in growth phase, with domain registration dating from 2021 and a focus on premium service offerings to differentiate from competitors.

Security posture

The current security posture of the website is moderate but with notable gaps. The absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces protection against common web attacks like clickjacking and MIME sniffing. The use of an outdated jQuery version (1.11.1) poses potential vulnerabilities if not patched or mitigated. No privacy or cookie policies are present, which is a compliance risk under GDPR and similar regulations. There is no evidence of vulnerability disclosure or incident response mechanisms, limiting the ability to manage security incidents effectively. SSL usage is assumed but not confirmed in the data; ensuring strong TLS configuration is essential. Overall, the site would benefit from implementing modern security best practices, updating libraries, and publishing clear security and privacy policies.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Update jQuery and other JavaScript libraries to the latest secure versions to mitigate known vulnerabilities.
  3. Publish clear privacy and cookie policies on the website to improve compliance and user trust.
  4. Establish and publicize a vulnerability disclosure policy and incident response contact information.
  5. Conduct regular security audits and penetration testing to identify and remediate potential vulnerabilities.

Technical notes

Notes

The website uses a classic web technology stack with jQuery 1.11.1 and Slider Revolution for interactive content. Google Fonts are used for typography. The site is hosted likely by Gabia, a Korean hosting provider, as inferred from registrar and DNS information. Performance is moderate with full-screen slider content and video backgrounds, which may impact load times. Mobile optimization is good, with responsive design elements present. SEO is basic with meta tags and Open Graph data but lacks structured data like JSON-LD. Accessibility features are minimal but present. The site does not use a CMS or modern JavaScript frameworks, indicating a traditional development approach. Technical debt is present due to outdated libraries and missing security enhancements, suggesting opportunities for modernization and improved maintainability.
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.
