The classified media cabinet is a high-security confidentiality device certified by the national administrative department for secrecy protection, specifically designed for storing and handling sensitive media such as classified documents, removable storage media (e.g., encrypted USB drives, hard disks), and confidential notebooks. According to the "Law on Guarding State Secrets" and BMB36-2019 "Confidentiality Management Requirements for Classified Media," classified media cabinets must be certified by the National Secrecy Science and Technology Evaluation Center (hereinafter referred to as "National Secrecy Evaluation") to ensure their physical security, electronic protection, and audit traceability capabilities comply with national confidentiality protection standards.

Core Functions:

Anti-Theft: Resists violent destruction, technical lock-picking, and other means.

Anti-Leakage: Equipped with electromagnetic protection functions to prevent wireless information theft.

Traceability: Maintains complete access logs to ensure accountability.

II. Core Functions and Technical Requirements of Classified Media Cabinets

1. Physical Security Protection

Cabinet Material: Made of cold-rolled steel plate with a thickness of 8mm or more; some high-security cabinets use 10mm steel plate + anti-drill composite materials. The cabinet door is equipped with a multi-point linkage locking structure (at least 3 locking bolts) to resist damage from tools such as hydraulic cutters and electric drills.

Locking System: Mechanical lock (Grade C lock core) + electronic password/IC card; some high-security models support fingerprint + iris recognition. Capable of resisting electromagnetic pulse (EMP) attacks.

2. Intelligent Management and Auditing

Three-level permission management (administrator, approver, user), supporting dynamic authorization (e.g., temporary meeting access). Stores ≥100,000 operation records, including cabinet opening time, personnel, and operation type, with encrypted and tamper-proof data storage. Triggers audible and visual alarms for violent break-ins, illegal movement, or multiple incorrect passwords, and synchronizes with the security system.

3. Environmental and Electromagnetic Protection

Tested according to the GB/T 9978.1 standard, fire-resistant for ≥1 hour at 950°C. Uses metal protective layer + filtering circuit, with protection effectiveness ≥30dB (1GHz frequency band), preventing wireless information theft. Built-in temperature and humidity sensors automatically activate dehumidification devices (when humidity > 60%).

III. Typical Application Scenarios of Classified Media Cabinets

1. Party and government agencies: Store confidential and secret-level documents, implementing "dual-person dual-lock" management to ensure "who uses, who is responsible."

2. Military units: Equipped with anti-electromagnetic leakage (TEMPEST) models for storing combat plans and materials.

3. Research institutes: Manage classified research data, supporting biometric + dynamic password composite authentication.

4. Confidential meeting rooms: Temporarily authorize participants to access files, automatically clear the cabinet after the meeting, and generate audit reports.
