The purpose of a _______is to deny network access to local area networks and other information assets by unauthorized wireless devices.

A Wireless Analyzer passively captures and inspects wireless traffic for troubleshooting or auditing, but does not enforce any access control to block unauthorized devices.

A Wireless Jammer indiscriminately disrupts all wireless signals in a frequency range, which is illegal in most jurisdictions and does not selectively deny specific unauthorized devices.

A Wireless Access Point provides the radio infrastructure for wireless connectivity but does not by itself enforce access control - that policy function belongs to an ACL or similar mechanism.

A Wireless Access Control List (ACL) contains ordered rules that explicitly permit or deny network access to wireless devices based on identifiers like MAC addresses or IP ranges. It is the mechanism specifically designed to block unauthorized wireless devices from reaching LAN resources and information assets. Without an ACL, any device that can associate with an access point could potentially reach internal network assets.
