Definition
B1 security is a computer security level defined by the Trusted Computer System Evaluation Criteria (TCSEC) to protect sensitive information, including military plans, classified government data, and staff personal details. It introduces strict system controls, ensuring users can only access data based on their clearance level and need to know.
B1 security also involves auditing to monitor any changes or access to the data. Essentially, this is a way to ensure only the right people access the right information, and everything is recorded to catch any suspicious activity.
How B1 Security Works
User clearance: Each system user is assigned a clearance level that dictates the information they can access:
- Data classification: Data is categorized into different levels, and only authorized people can access specific types of classified data.
- Access control: The system verifies users’ clearance level before allowing or blocking them from accessing information.
- Auditing: The system records every time someone accesses or changes information, allowing administrators to monitor user actions and flag suspicious activities.
What Information Does B1 Security Protect?
- Intelligence operations, national security, and defense strategies.
- Defense systems, military missions, and troop movements.
- Proprietary technologies, trade secrets, and corporate strategies.
- Sensitive personal information, including medical records, social security numbers, and financial data.
- New technologies, scientific research, and innovative products.
