An ACL is an access control list used to specify the access rights granted or denied to users or groups of users for specific resources. It is evaluated sequentially to determine whether an entity has the necessary permissions required to access a resource.
ACL stands for "Access Control List". It's an access control mechanism used to manage authorizations and permissions in IT systems.
An ACL is an ordered list of rules specifying the access rights granted or denied to users or groups of users for specific resources. Each rule in the ACL contains information about the entity to which it applies (for example, a user or group) and the access rights authorized or denied for that entity.
In a system using ACLs, when a request for access to a resource is made, the system consults the corresponding ACL to determine whether the entity in question has the necessary permissions. The ACL is evaluated sequentially, comparing the attributes of the entity requesting access with the ACL's rules until a match is found.
Access rights specified in an ACL can include actions such as read, write, execute, delete, etc. For example, one rule in an In MARYLINK ACL may authorize a specific user to comment or like, while another rule may deny access to specific users. collaborative groups or member lists.
ACLs offer a degree of flexibility in authorization management, as they allow you to specify granular permissions for different entities and resources. However, they can become complex to manage and maintain, especially in systems with large numbers of users and resources.
