Description: A network access control list (ACL) is a set of rules used to control inbound and outbound traffic at the network level. These rules determine what traffic is allowed or denied based on specific criteria such as IP addresses, protocols, and ports. ACLs are fundamental in network security management as they allow administrators to define access policies that protect network resources. Network ACLs can be applied to various network environments, providing an additional layer of security for traffic entering and leaving network devices and services. Network ACLs are stateless, meaning each packet is evaluated independently, without regard to the connection state. This contrasts with security groups, which are stateful and keep track of connection states. ACLs can be configured to allow or deny traffic based on specific rules, enabling granular control over access to network resources. Their implementation is crucial for compliance with security regulations and for protecting sensitive data in diverse environments.
