Access control systems are very reliable and will last a long time. ABAC can also provide more dynamic access control capability and limit long-term maintenance requirements of object protections because access decisions can change between requests when attribute values change. Access control can also be integrated with other security systems such asburglar alarms,CCTV systems, andfire alarms to provide a more comprehensive security solution. Rule-based access control is based on rules to deny or allow access to resources. Both the RBAC and ABAC models have their advantages and disadvantages, as we have described in this post.
