A safeguard, or countermeasure, is anything that mitigates or reduces vulnerability. Safeguards are the only means by which risk is mitigated or removed. It is important to remember that a safeguard, security control, or countermeasure may not always involve procuring a new product; effectively utilizing existing resources could also help produce safeguards.
The following are some examples of safeguards:
- Installing antivirus on all the systems
- Installing a network firewall
- Installing CCTVs and monitoring the premises
- Deploying security guards
- Installing temperature control systems and fire alarms
