• It includes two types and they are as follows:
  • Bell-LaPadula (BLP) confidentiality model.
  • Biba Integrity model.

Comparison of Bell-LaPadula confidentiality model and Biba Integrity model:

• Bell-LaPadula confidentiality model and Biba Integrity model are two most extensively used access control methods.
• These methods are developed to validate mechanisms to secure the system privacy and data integrity in the computer system...
