A user gets a warning message reading "ACCESS DENIED; You are not cleared for this data!! " when attempting to access a file. The user needs some of the information in the file to complete a report so they get an administrator, who can override the restriction to put a copy of it into their "home directory". If the system conformed to the Bell-LaPadula security model, select the rules that were bypassed. (select two)
Star property as well as the invocation property
Simple property
Star property
Bell-LaPadula is a multi level security model restricting subjects read and write access to objects based on security labels. ___The star property restricts write access to lower security levels, the override (if possible) violated this rule. ___The simple rule restricts read access to data above a users clearance, this rule was also violated.____The invocation rule seems plausible, but applies to the Biba security model. ___Need to know is not a reason to break rules.
Question: If the file was copied and the user only has access to that copied file, how does this violate the star property? The user is still unable to write to the original file.
