Final answer:
A preventative control measure is deployed to deter security policy violations. These include firewalls, ACLs, user authentication, and security training. They act as a first line of defense in information security.
Step-by-step explanation:
A preventative control measure is deployed to discourage violation of security policies.
Preventative controls are mechanisms put in place to prevent security incidents before they occur. They play a critical role in protecting information systems by deterring users from unintentionally or maliciously compromising security. Examples of these measures include firewalls, access control lists (ACLs), strong user authentication methods, and security awareness training. These controls serve as a first line of defense, aiming to reduce the risk of unauthorized access, data breaches, and other forms of cyber threats.
