Secure firewall , Access Control Lists (ACLs) , and Bastion hosts

Explanation:

In this scenario, the best options to be able to accomplish this would be a Secure firewall , Access Control Lists (ACLs) , and Bastion hosts. A secure firewall and an access control list will prevent specific harmful files and computers from entering a network unless it has the proper clearance. A bastion host on the other hand is a special-purpose computer on a network specifically designed and configured to withstand attacks, acting as a secondary defense mechanism.
