Adaptive Trust-Based Access Control with Honey Objects and Behavior Analysis

In recent years, the number of interconnected computers and resources has increased drastically. To ensure the privacy of these resources, a secure access control mechanism must be implemented. Traditional access control models lack adequate emergency handling. Threshold-based collaborative access control (T-CAC) addresses the issue of handling emergencies without overriding the access control model by shifting trust from individuals to groups, thereby enforcing collaboration among different actors. Given the risks associated with improper and uncontrolled delegation of authority, along with the need to enforce the zero-trust principle of continuous verification, this study proposes a secure and adaptable model, Adaptive Trust-Based Access Control with Honey Objects and Behavior Analysis (ATACHOBA). It enables user delegation based on both trust and behavior analyses. In the proposed model, access decisions are determined by trust values and recommendations provided by the machine learning algorithm. ATACHOBA imposes penalties for any abnormal or malicious activity. Moreover, it utilizes honey objects and honey requests to ensure appropriate user behavior.
