B1 security definition
B1 security is a level of computer security defined by the U.S. government to keep sensitive information protected. This information could include classified government data, military plans, or staff personal details. It means the system controls who can access what, based on a user's clearance level and need to know.
B1 security also involves careful auditing to keep track of any changes or access to the data. It's essentially a way to make sure that only the right people see the right information, and everything is logged to catch any suspicious activity.

How B1 security works
- User clearance — Everyone who uses the system is assigned a clearance level. This level tells the system what information they’re allowed to see.
- Data classification — Information is also classified into different levels (like "confidential"). Only people with the right clearance can access certain types of classified information.
- Access control — The system checks both the user's clearance and the classification of the information before allowing access. If a user’s clearance matches or exceeds the classification, they can view the data. If not, they’re blocked from accessing it.
- Auditing — Every time someone accesses or changes information, the system records it in a log. This way, administrators can review who did what, which helps catch any unauthorized activity.
