The key elements of the audit that collectively ensure a thorough examination of your organisation's security posture include:
- Agree Scope: Clearly outline the systems, processes, and data to be audited.
- Risk Assessment: Identify and evaluate potential risks to the IT environment, including vulnerabilities and threats.
- Policy Review: Examine existing security policies, procedures, and compliance with regulations and standards.
- Assess Technical Controls: Evaluate the effectiveness of security technologies such as firewalls, intrusion detection systems, and encryption.
- Access Controls: Review user access levels and authentication methods to ensure proper access management.
