Classified Protection 2.0 assessment strictly requires equal emphasis on technical defense and security management. Simply deploying firewalls, bastion hosts, EDR and other security hardware only provides passive technical protection. Without complete, implementable and documented systems, third-party auditors will identify severe management gaps and reject the assessment. A compliant system framework must cover organization, personnel, asset, operation, data, emergency response and continuous improvement to form a closed loop: documented rules, standardized workflows, execution records and rectification tracking. This paper constructs a three-tier security system framework aligned with Classified Protection 2.0, ISO27001 and IPO internal control standards.
1. Top-Level Three-Tier System Architecture
Adopt the logic of General Principles → Special Management Measures → Detailed Operation Guidelines to realize clear hierarchy and divided responsibilities.
1. Tier 1: General Information Security Management Guideline Issued and signed by general manager, defining security objectives, organizational structure, senior management accountability and universal security baseline, serving as the upper legal basis aligned with Cybersecurity Law and Classified Protection standards.
2. Tier 2: Special Security Management Measures Ten core specialized documents covering all assessment dimensions of Classified Protection 2.0, specifying cross-department responsibility boundaries and standardized control rules.
3. Tier 3: Operation Guidelines & Standard Ledger Forms Standardized approval templates, inspection records, drill reports and rectification tracking sheets, converting abstract rules into archivable evidence for on-site audit.
2. Core Tier-2 Special Security Management Measures
1. Security Organization & Personnel Management Clarify responsibilities of senior security leading group, dedicated security administrators and department security contacts; regulate induction training, regular security education, offboarding permission recovery; control access of outsourced vendors with confidentiality agreements and rotation audit for privileged operation posts.
2. Information Asset Classification & Grading Management Full inventory of servers, business systems, customer data and design documents; four-level classification of public/internal/sensitive/core confidential data; annual asset inventory and risk list update.
3. Computer Room Physical Security Management Standardize access registration, visitor escort, hardware change approval, daily patrol of temperature, fire protection and UPS, with long-term retention of surveillance records.
4. Account, Permission & Privileged Operation Management Enforce least privilege principle and MFA authentication; time-limited temporary accounts for outsourced staff; quarterly permission review to recycle idle and over-authorization accounts; formal approval process for bastion host maintenance.
5. Network & Terminal O&M Management Regulate network zone policy change approval, periodic unused port cleanup, remote zero-trust access rules, USB peripheral lock and patch testing workflow for servers and terminals.
6. Data Security & Leakage Prevention Management Control external transmission approval of financial, customer and R&D data; regulate high-risk database operation review; standardize backup and offsite disaster recovery, and data breach reporting workflow in compliance with PIPL.
7. System Change & Pre-Launch Security Management Mandate risk assessment and rollback plans before version release or configuration modification; isolate test and production environments with mandatory code vulnerability scanning.
8. Security Audit & Risk Assessment Management Enforce log retention for over 6 months; quarterly vulnerability risk assessment and annual full-scale risk evaluation with closed-loop rectification tracking for high-risk loopholes.
9. Emergency Response & Disaster Recovery Management Classified response plans for ransomware, data leakage and website attacks; semi-annual emergency drills with review reports; regular backup recovery verification tests.
10. Security Assessment & Continuous Improvement Management Set departmental security KPIs and violation punishment standards; track rectification items from internal inspections and third-party assessments; annual document review and revision mechanism.
3. Tier-3 Supporting Ledger & Record Forms
A complete set of archivable supporting documents serves as core audit evidence, including personnel training records, asset inventory sheets, computer room access logs, permission review forms, vulnerability rectification ledgers, data export approval slips, emergency drill reports and annual system revision records.
4. Long-Term Implementation Mechanism to Avoid Formalistic Documents
1. Senior management accountability: General manager takes primary security responsibility, with department heads held accountable and security performance included in annual KPIs.
2. Regular training mechanism: Mandatory induction security training and quarterly company-wide security awareness education with archived training records.
3. Monthly internal self-inspection: IT security team reviews system execution and tracks all identified risks to full closure.
4. Dynamic document update: Annual full review of all security systems, with timely revisions triggered by business expansion, new cybersecurity laws and security incidents.
5. Third-party pre-assessment coordination: Pre-check the system framework before annual Classified Protection evaluation to fill management gaps, meeting ISO27001 and IPO internal control requirements simultaneously.
In conclusion, Classified Protection 2.0 compliance relies on dual pillars: technical security equipment and standardized management systems. Hardware mitigates technical attack risks, while a complete three-tier security system addresses human-induced vulnerabilities and process defects. Combined with standardized ledgers and sustainable execution mechanisms, it forms a traceable closed-loop management system to cover all management-type assessment control points that pure hardware deployment cannot satisfy, enabling enterprises to pass official assessment and maintain long-term compliance status.
