The primary purpose of access controls in information security is to manage and restrict who can view or use resources within an organization. Access controls ensure that only authorized users gain entry to sensitive information and systems, protecting them from unauthorized access or data breaches. This can be achieved through various methods such as authentication, authorization, and auditing. By implementing strong access control measures, organizations can maintain their overall security posture, comply with regulatory requirements, and safeguard critical data from potential threats and vulnerabilities.
