3. มาตรฐาน Best Practices / Frameworks (De facto Standards)
| Framework | ผู้พัฒนา | ลักษณะ |
|---|
| CIS Controls (v8) | Center for Internet Security | 18 Critical Controls, Implementation Groups (IG1/2/3), Prioritized, Actionable |
| CIS Benchmarks | CIS | Hardening Guides: OS, Cloud, Network Devices, Kubernetes, Database |

Network Security Requirements (ข้อกำหนดพื้นฐาน)
- Patch & Update Management - Firmware, OS, Apps, Libraries (Critical < 72 hrs)
- Strong Authentication - MFA, Certificates, Passwordless (FIDO2/WebAuthn)
- Secure VPN/Remote Access - Zero Trust Network Access (ZTNA) แทน VPN แบบเดิม
- Access Control / Least Privilege - RBAC, ABAC, PAM, JIT Access
- Account Lifecycle Management - Provisioning, Review, Deprovisioning (Automated)
- Network Segmentation - VLAN, VRF, Micro-segmentation, Zero Trust Segmentation
- Encryption - TLS 1.2+ (Data in Transit), AES-256 (Data at Rest), IPsec/MACsec (Link)
- Monitoring & Logging - NetFlow, SIEM, NDR, EDR, XDR, SOAR
- Vulnerability Management - Continuous Scan, Risk-based Prioritization, Automated Remediation
- Incident Response - Plan, Playbooks, Tabletop, Forensics Readiness
Network Security Devices มาตรฐาน
- Firewall (Next-Gen) - App-ID, User-ID, Content-ID, SSL Decryption, IPS, Sandbox
- Switch/Router với Security Features - ACL, 802.1X, MACsec, CoPP, uRPF, DHCP Snooping, DAI, IP Source Guard
- Wireless Controller/AP - WPA3, 802.1X, WIPS, Rogue Detection, Client Isolation
- Load Balancer / ADC / WAF - L7 Protection, Bot Mitigation, API Security
- Proxy / Secure Web Gateway - Forward/Reverse, TLS Inspection, DLP, RBI
- Network TAP/SPAN + Packet Broker - Visibility для Tools
Thailand Context: มาตรฐานที่เกี่ยวข้อง
- PDPA (Personal Data Protection Act B.E. 2562) - ข้อมูลส่วนตัว, Consent, DPO, Breach Notification
- Cybersecurity Act B.E. 2562 - Critical Information Infrastructure (CII), NCSA, Incident Reporting
- ETDA Guidelines - e-Transactions, Digital ID, Certificate Authority
- BOT Notifications - Financial Institutions: IT Security, Outsourcing, Cloud, BCP
- ISO 27001 Certification - มาตรฐานที่ยอมรับอย่างกว้างขวางในไทย
Security Governance Principles (ISO 27014 / COBIT)
- Responsibility - กำหนดหน้าที่ชัดเจน (Board → CISO → Owners)
- Strategy - Security Strategy สอดคล้อง Business Strategy
- Acquisition - การจัดหา/พัฒนาระบบ มี Security Built-in
- Performance - วัดผล KPIs, Metrics, Maturity Models
- Conformance - ปฏิบัติตาม Laws, Regulations, Policies, Standards
- Human Behavior - Culture, Awareness, Training, Ethics
บทบาทของมาตรฐาน (Role of Standards)
- Interoperability: ระบบต่าง廠商 ทำงานร่วมกันได้ (TLS, IPsec, SAML, OIDC, RADIUS)
- Common Language: คำศัพท์ร่วมกัน (CVE, CVSS, MITRE ATT&CK, STIX/TAXII)
- Baseline/Minimum Bar: ระดับขั้นต่ำที่ยอมรับได้ (CIS Benchmarks, PCI DSS)
- Auditability/Compliance: ตรวจสอบได้ วัดได้ รับรองได้ (ISO 27001, SOC 2)
- Risk Reduction: ใช้ Best Practices สะสมมาหลายทศวรรษ
- Vendor Neutrality: ไม่ติด Vendor Lock-in (Open Standards)
สรุป: ใคร Set Standards?
ไม่มีคนเดียว - เป็น Ecosystem ของ: ISO/IEC, NIST, IETF, IEEE, ITU (Formal Standards) + PCI, HIPAA, NERC (Regulatory) + CIS, MITRE, Zero Trust, SASE (Best Practices) + Vendors (Palo Alto, Cisco, Fortinet, Microsoft, Cloud Providers) (Implementation/De facto) → องค์กรเลือก Adopt/Map ตาม Risk Profile, Industry, Geography, Maturity
