What does hardening a system primarily achieve?

  1. It encrypts the system's stored data
  2. It applies all outstanding vendor patches
  3. It removes unused services, default accounts and unnecessary ports, so there is less to attack and to patch
  4. It isolates the system on its own network segment
Show the answer

Answer: C. It removes unused services, default accounts and unnecessary ports, so there is less to attack and to patch

Hardening reduces what exists. Patching, encryption and segmentation are separate controls.
