Access control is the process of regulating who or what is allowed to access a system, resource, or location. It is a security measure that is used to ensure that only authorized individuals or systems are able to access sensitive or confidential information or resources. [1]. Access control can be implemented in a variety of ways, such as through the use of passwords, security tokens, or biometric authentication [2] [3]. It can also involve physical security measures, such as locks or barriers, to control access to a specific location.
Access control systems can be used to ensure compliance with regulations in some jurisdictions, such as Health Insurance Portability and Accountability Act (HIPAA)[4][5], and Payment Card Industry Data Security Standard (PCI DSS)[6][7].
