Implementingsecurity measuresto protect the database against unauthorized access.

The correct answer is D — Removing all end-of-life devices from the network.

According to WGU Cybersecurity Architecture and Engineering (KFO1 / D488), end-of-life systems pose significant risks because they no longer receive patches or updates. The besthardening technique in this situation is to decommission and remove these devices, eliminating their vulnerabilities altogether.

Access control (A), vulnerability scanning (B), and IDPS (C) are helpful practices but do not eliminate vulnerabilities of unsupported devices.

Reference Extract from Study Guide:

"Removing end-of-life or unsupported assets is essential for maintaining a secure infrastructure, as these devices are highly vulnerable to exploitation."
