What role does a Preventative Control serve in security?

A Preventative Control plays a crucial role in security by actively neutralizing potential threats before they can materialize into actual incidents. This proactive approach involves implementing security measures and practices designed to stop attacks or unauthorized access before they occur, thereby safeguarding assets and ensuring system integrity.

For instance, preventative controls may include firewalls, intrusion detection systems, encryption, and employee training on security awareness. These measures help create a barrier against potential threats, making it significantly more difficult for an attacker to execute their malicious intentions.

The essence of preventative controls lies in their forward-looking nature, as they aim to anticipate and thwart security breaches before they happen, rather than reacting to them after the fact.
