An access control list (ACL) is a table that tells a computer operating system which access rights each user has to a particular system object, such as a file directory or individual file. Each object has a security attribute that identifies its access control list..
Similarly, what is Access Control List in networking?
An Access Control List (ACL) is a set of rules that is usually used to filter network traffic. ACLs containts a list of conditions that categorize packets and help you determine when to allow or deny network traffic. They are applied on the interface basis to packets leaving or entering an interface.
Secondly, what are the types of access control list? There are two main different types of Access-list namely:
- Standard Access-list – These are the Access-list which are made using the source IP address only. These ACLs permit or deny the entire protocol suite.
- Extended Access-list – These are the ACL which uses both source and destination IP address.
Thereof, what is Access Control List?
An access-control list (ACL), with respect to a computer file system, is a list of permissions attached to an object. An ACL specifies which users or system processes are granted access to objects, as well as what operations are allowed on given objects. Each entry in a typical ACL specifies a subject and an operation.
What is Access Control List Cisco?
Access control lists (ACLs) perform packet filtering to control which packets move through a network and to where. The packet filtering provides security by helping to limit the network traffic, restrict the access of users and devices to a network, and prevent the traffic from leaving a network.

An ACL or Access control list is a common means by which access to and denial of services is controlled.
