Multi-Level Security Lattice: Bell-LaPadula for Government Systems

Government systems don't secure data with a single wall — they classify every document into ordered tiers (Unclassified, Confidential, Secret, Top Secret) and grant every user a matching clearance, then mechanically enforce two inequalities on every access attempt. This simulator renders that lattice as four stacked 3D shelves: pick a subject's clearance level and a target document's classification, choose Read or Write, and fire a request pulse that the lattice evaluates in real time using the actual Bell-LaPadula ss-property ("no read up") and *-property ("no write down"). A automated request-stream control lets you watch the enforcement engine process a continuous flow of attempts the way a real policy-enforcement point does, with live counts of allowed requests and denials broken out by which rule stopped them.
