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
