What is ACL (Access Control List)

This video is about the ACL access control list. Today, in this video you will learn what is Access Control List and how it works. In addition to that, you will understand where do we use ACL and on what devices it is configured for. More importantly, you would be able to know how does ACL monitor network traffic and how it improves network performance and security

Furthermore, ACL has been explained based on the working mechanism and has also been categorised based on traffic identification.

ACL is a security mechanism used in computer systems and networks to control and manage access to resources, such as files, folders, devices, or network services. An ACL consists of a list of permissions or rules that define who can access a particular resource and what actions they can perform on it.

Typically, an ACL is associated with an object or a set of objects, and each entry in the list specifies a user, group, or system process and the permissions granted or denied to them. These permissions can include read, write, execute, delete, or modify rights, among others. When a user or process attempts to access a resource, the system checks the ACL to determine whether the requested action is allowed or denied.

ACLs are commonly used in operating systems like Windows, Unix, and Linux, as well as in network devices, routers, and firewalls. They provide a flexible and granular approach to managing security by allowing administrators to define specific access rights for individual users or groups. This enables organizations to enforce security policies, protect sensitive data, and ensure that only authorized entities can interact with resources.
