Overview :

In networking, blacklisting and whitelisting are access control methods used to manage which devices can or cannot connect to the network.

  • A Blacklist is a list of restricted entities (such as MAC addresses or IP addresses) that are explicitly denied access. It enhances network security by blocking unauthorized or potentially malicious devices. 
  • A Whitelist is a list of approved entities that are explicitly allowed to connect. Devices not included in the whitelist are denied access.
 

Use Case (MAC Address-Based Control) 

Since every device has a unique MAC address, administrators often use it to control network access: 

  • Add to Blacklist: Blocks a device’s MAC address, preventing it from connecting. 
  • Remove from Blacklist: Allows a previously blocked device to connect again. 
  • Add to Whitelist: Ensures only approved devices with listed MAC addresses can connect. 
  • Remove from Whitelist: Revokes access for that device, denying future connections.
