What Are Two Uses Of An Access Control List? (Choose Two.)

What are the two uses of an access control list? (Choose two.)

• ACLs work by managing the areas which help the host to have access to a network.
• ACLs give the security for access to networks.
• ACLs prevent any access to the specified application and ports.
• It can give permission or stop the traffic based on MAC address and their origin is the router.
• ACLs help the router to find the best possible path toward the destination.

Answer: Some of the uses of the ACLs are: 

• For effective network performance, it can limit the traffic.
• The routes which are updated are restricted for delivery.
• It gives security on a basic level.
• The traffic is filtered on the types being sent.
• IP addressing is also base for traffic filtering.

What are ACLs?

ACLs is the access control list which is defined as the rules set which help either the user or the system has access to the specific object or the service/resources.it is installed either in the router or switched, and it works to filter the traffic and maintain the traffic is allowed to access the network.

The systems are given the attribute for security which finds systems ACL. The list has the collection of the user who is allowed to access the system. The file system ACL has a special feature that allows to read the file present in the directory, rewrite the files, execute them if the file is executable. ACLs are also developed in operating systems like Windows, Linux, and in-network interfaces. in the network of computer, ACL work to restrain or give access to specific types of traffic. Mostly they filter the traffic on the base of source and destination.

Reason to use the ACLs:

The reason to use the ACL is to control the permission of the system or network of the computer.it is used to filter the incoming or outgoing traffic of the devices. The devices might be the networks that work as gateways or the endpoint for a network that is accessible directly by the user.

In the system, the users are given the control with some restriction according to their levels and roles, such as a user in the network administrator allowed to read, write or update for the sensitive files. On the other hand, some users are only allowed to read the files. ACL help to arrange the traffic for the efficient performance of the network and provide the network administrator control over the users in the network or system. one of its use is to provide security by restricting the malicious traffic.

Access control list has two types which are discussed in the following:

• File system: it can work by maintaining access to the files and directories.it gives a guideline to operating systems that generate user access permission and the benefits of the system once it is accessed.
• Networking: networking ACL works by instructing switches and the router of the network whose work to specify the traffic types which have the permission to the interface along with the network. in the network administrator, the networking ACLs rules are predefined, that’s why they work like the firewalls.
