Explanation
An Access Control List (ACL) is a set of rules applied to interfaces or resources that explicitly permits or denies traffic or access based on defined criteria.
Common mistakes.
- A. Spoofing is an attack technique where a malicious actor forges source information (such as an IP address) to impersonate a trusted entity - it is not an access control mechanism.
- C. System hardening is the process of reducing a system's attack surface by disabling unnecessary services and applying patches, but it does not directly allow or deny access to specific network resources.
- D. NFS (Network File System) is a distributed file sharing protocol that enables remote file access, but it is not itself a mechanism for allowing or denying access to network resources.
Concept tested. ACL permit and deny network resource access
