Information Security Auditing is the process of systematically evaluating an organization's information systems, policies, and controls to ensure the confidentiality, integrity, and availability of data. It involves assessing compliance with security standards, identifying vulnerabilities, and recommending improvements to mitigate risks. Security audits can be internal or external and typically include reviewing access controls, network security, data protection measures, and incident response plans. By conducting regular audits, organizations can enhance their cybersecurity posture, prevent data breaches, and ensure regulatory compliance.
