Unauthorized access is the act of gaining access to computer systems, networks, data, or resources without permission from the owner or administrator. This security breach can involve exploiting vulnerabilities, using stolen credentials, or bypassing security measures to view, modify, or steal sensitive information. Unauthorized access poses significant risks, including data breaches, loss of sensitive information, and potential damage to an organization’s reputation and operations. To prevent unauthorized access, organizations must implement robust security measures such as strong authentication, access controls, encryption, and regular security audits.
