Answer: C - In the 1970s, the U.S. military developed the Bella-LaPadula security model to address the concerns of information leaks. It was the first mathematical model of a multilevel security policy used to define the concept of a secure state machine and modes of access and outlined release of access. Its development was funded by the U.S. government to provide a framework for computer systems that would be used to sort and process sensitive information. The model’s main goal was to prevent secret information from being accessed in an unauthorized manner. This model uses a lattice of security levels to ensure unauthorized individuals cannot access sensitive data.
