What is the purpose of preventative controls?

The purpose of preventative controls is primarily to prevent unauthorized access to resources. These controls are designed to establish safeguards that deter potential threats before they can manifest into actual security incidents. By implementing measures such as firewalls, access controls, and encryption, organizations can significantly reduce the risk of breaches and protect sensitive information from being accessed or compromised.

Preventative controls serve as the first line of defense in an organization's security strategy, aimed at stopping threats before they can exploit vulnerabilities. This approach is fundamental because it focuses on mitigating risks through proactive measures, rather than responding to threats that have already gained access or led to security incidents. By effectively preventing unauthorized access, organizations can ensure their resources remain secure and maintain the integrity, confidentiality, and availability of their data.
