The security policies consisting of MAC, Clark Wilson, LOMAC and ABAC, as proposed in this
research, are implemented and devised using ACPT by specifying the attributes for subject, resource,
actions, environmental attributes and the associated permission. Access Control Policy Tool (ACPT) is a
policy specification tool developed by National Institute of Standards and Technology (NIST) and North
Carolina University [13]. ACPT is used to reduce human error and inaccuracy found in security policies
crafted by administrators, through the rigorous verification of the security policies. As there is a limitation
in term of space, only result of MAC is displayed here. The disclosure of other result is upon request.
