NCSA Website Security Standard Compliance
Thailand's National Cybersecurity Committee (กมช.) under NCSA has issued mandatory Website Security Standards B.E. 2568 (Version 1.0) under the Cybersecurity Act B.E. 2562 (2019). These standards are mandatory for government agencies and CII operators, and recommended for private enterprises.
What are the NCSA Web Security Standards?
The "Website Security Standard Version 1.0" (มาตรฐานการรักษาความมั่นคงปลอดภัยสำหรับเว็บไซต์ พ.ศ. 2568) establishes mandatory security requirements issued by the National Cybersecurity Committee (กมช.) under the National Cyber Security Agency (NCSA/สกมช.), pursuant to the Cybersecurity Act B.E. 2562 (2019). Published in the Royal Thai Government Gazette on 16 September 2025, these standards set minimum security requirements for websites operated by government agencies, regulatory and supervisory bodies, and Critical Information Infrastructure (CII) organizations. The standard applies the "High Water Mark" principle, assessing risks based on the CIA triad (Confidentiality, Integrity, and Availability), and is also recommended for adoption by private enterprises.

Who Must Comply?
The NCSA Web Security Standards are mandatory for government agencies, regulatory and supervisory bodies, and Critical Information Infrastructure (CII) operators. Private enterprises are also encouraged to adopt the standards as a security framework.
Government Agencies
All government organizations operating public-facing websites and web applications
Financial Services CII
Banks, securities firms, insurance companies, and payment service providers designated as CII
ICT & Telecom CII
Information and communication technology providers and telecommunications operators
Energy & Utilities CII
Energy providers and public utility organizations operating critical web systems
Transportation CII
Transportation infrastructure operators with web-based services and systems
Healthcare CII
Healthcare organizations operating websites handling sensitive patient information
Key NCSA Security Requirements
The standards define comprehensive security requirements for web applications across multiple domains.
Web Vulnerability Assessment & Penetration Testing
Conduct continuous vulnerability assessments scanning internet-accessible assets for known CVEs and misconfigurations. Penetration testing must be performed at least annually, targeting OWASP Top 10 vulnerabilities including XSS, SQL Injection, and broken authentication.
Secure Development Practices
Implement a Secure Software Development Lifecycle (SSDLC) including secure coding standards, code review processes, and pre-deployment security testing. Secure code review is highly recommended to eliminate OWASP Top 10 flaws at the source code level.
SSL/TLS & DNSSEC Configuration
Enforce HTTPS with TLS 1.2 or higher, strong cipher suites, valid certificates, and HSTS headers. Implement DNSSEC for DNS security across all web properties.
Access Control & Authentication
Implement robust access control mechanisms with Multi-Factor Authentication (MFA) for administrative access and sensitive systems. Enforce strong session management controls and role-based authorization.
Incident Response for Web Attacks
Establish documented procedures for detecting, responding to, and recovering from web-based security incidents including defacement, data breaches, and DDoS attacks.
Security Monitoring & Logging
Implement comprehensive logging of web application events, security monitoring systems, and regular log review processes for anomaly detection.
Consequences of Non-Compliance
The NCSA enforces these standards under the authority of the Cybersecurity Act B.E. 2562 (2019), which provides enforcement mechanisms for non-compliant organizations.
NCSA can issue compliance orders requiring CII organizations to implement specific security measures within a defined timeframe. Failure to comply with orders may result in escalated enforcement actions.
Organizations that fail to meet CII obligations under the Cybersecurity Act face administrative penalties. NCSA has authority to impose corrective measures and sanctions on non-compliant CII operators.
Non-compliance with NCSA standards may be disclosed through regulatory reporting channels, affecting organizational reputation, public trust, and business relationships with government entities.
