Which of the following is NOT a benefit of implementing a firewall?

Implementing a firewall offers several benefits that primarily revolve around controlling and monitoring network traffic. One of the key advantages of a firewall is traffic filtering, which allows organizations to set rules that determine what types of traffic are permitted or denied. This capability helps to block unwanted access and potential threats from entering the network.

Another significant benefit is the enhancement of network performance. Firewalls can help manage bandwidth usage by controlling and limiting traffic, which can lead to improved overall performance of the network.

Enhanced security is also a primary benefit of firewalls. They serve as a barrier between trusted internal networks and untrusted external networks, actively preventing unauthorized access and cyber threats.

However, secure data encryption is not a function typically associated with firewalls. Firewalls primarily focus on traffic management and access control rather than encrypting data. Encryption is a separate process that involves encoding data to prevent unauthorized access, typically handled by other security mechanisms, such as encryption software or protocols. Therefore, secure data encryption is not a direct benefit of firewall implementation.
