What does ACL stand for in the context of network security?

In the context of network security, ACL stands for Access Control List. This term refers to a set of rules that manage permissions for which users or systems have access to specific resources within a network. An Access Control List defines the conditions under which those permissions are granted or denied, allowing network administrators to regulate who can view or modify files and other resources.

ACLs are commonly used in various networking devices, such as routers and firewalls, to enhance security by controlling traffic flow and ensuring that only authorized users can access sensitive data. Understanding ACLs is essential for maintaining the integrity and confidentiality of information within a network environment.

The other options do not accurately represent the established meaning of ACL in network security. Access Control Level does not correspond with the standard terminology used in this context. Applied Control Layer and Access Control Log also fail to capture the concise and functional definition that an Access Control List provides in the realm of network security.
