Multi-Level Security System Which Restricts Covert Channel by Using Switch DGS-3627
Multilevel security or Multiple Levels of Security (MLS) is that the application of a methoding system to process info with completely different sensitivities (i.e., at completely different security levels), allow synchronic access by users with completely different security clearances and needs-to-know, and stop users from getting access to info that they lack authorization. MLS permits quick access to less-sensitive info by higher-cleared people, and it permits higher-cleared people to simply share alter documents with less-cleared people. A alter document is one that has been altered to get rid of info that the less-cleared individual isn't allowed to envision.
