Classified information can be safeguarded by using several robust methods and technologies such as strict access controls, encryption, physical security, document rights management (DRM) systems, and attribute-based access controls.
Key Methods to Safeguard Classified Information
- Access Controls : Controlling access to classified information through strict authentication methods like multi-factor authentication, ensuring only authorized personnel with proper clearance and need-to-know access can view or handle the information.
- Encryption : Using advanced encryption techniques like AES 256-bit to secure data at rest and in transit, making it unreadable without the appropriate decryption keys.
- Document Rights Management (DRM) : Applying DRM solutions such as Locklizard Safeguard, which protect documents from unauthorized copying, editing, printing, or sharing, and allow for automatic expiry, access revocation, and dynamic watermarks.
- Physical Security : Securing physical access to classified information through measures like secure facilities, surveillance, access-controlled environments, and approved security containers or locks.
- Attribute-Based Access Control (ABAC) : Employing data-centric security models to dynamically enforce fine-grained access policies based on user attributes, device, time, location, and document sensitivity.
- Need-to-Know and Need-to-Share Principles : Restricting access strictly to those authorized while enabling secure sharing with coalition partners or other authorized entities under controlled conditions.
Together, these strategies and tools form a comprehensive approach to safeguarding classified information from unauthorized disclosure, leakage, or other security breaches.
