CSSLP Questions and Answers with 100%Correct Solutions. *-property - correct answer Pronounced "star property," this aspect of the Bell-LaPadula security model is commonly referred to as the "no-write-down" rule because it doesn't allow a user to write to a file with a lower security classification, thus preserving confidentiality. 3DES - correct answer Triple DES encryption—three rounds of DES encryption used to improve security. 802.11 - correct answer A family of standards that ...
