Compare cybersecurity frameworks and standards and emphasize implementing security controls around devices, systems, networks, and information; organizations typically select one framework and comply with industry standards.

Identify the four phases of the IT audit process—planning, fieldwork, reporting, and follow-up—and how cybersecurity audits fit as a type of IT audit performed by internal or external auditors.

Define the audit objective, determine the scope and risk considerations, plan sample size and methodology, and prepare for kickoff meetings and the PBC list requests during the planning phase.

During the fieldwork phase, the audit team gathers evidence, conducts control tests, and performs walkthroughs to assess end-to-end processes, identify control gaps, and test one with 10–20% sampling 40 samples.

Document and present audit results in reporting phase, based on control test outcomes; draft reports are sent to managers for remediation plans, followed by a final audit report by email.

The follow up phase verifies that corrective action plans are implemented and effective after the audit report is finalized, by obtaining evidence, updating procedures, retesting processes, and closing the deficiency.

Audit team follows a hierarchical structure, sized 15–25 auditors based on informational assets, with senior IT auditors, IT auditors, associate IT auditors, and non IT auditors reporting to a controller.

Plan the cybersecurity audit across the four phases, defining scope, objectives, risk, testing locations and the audit period. Assemble teams, assign applications and controls, and conduct a kick off meeting.

Test the design and operating effectiveness of controls in the fieldwork and gather evidence. Conduct walkthroughs with process owners and stakeholders, probe questions, and select samples to confirm consistent execution.

Test technical controls in field work, including identity and access management, data integrity, vulnerability management, patching, firewalls, intrusion detection, endpoint and network security with segmentation, incident and change management.

Test identity and access management controls, verify provisioning and deprovisioning, password configurations, privileged accounts, and access reviews to ensure segregation of duties.

Test password configuration against the organization's policy, verifying parameters like minimum length and expiry, and collect evidence via demonstrations and screenshots; propose controls like multi-factor authentication if gaps exist.

Assess access provisioning controls to ensure employees access systems aligned with their job function, verify the approval process, and test evidence from samples, manager approvals, or ticketing systems.

Test and enforce timely deprovisioning by documenting the revocation process, coordinating HR and tech, verifying removal evidence and access across all systems.

Examine how segregation of duties strengthens internal control by ensuring at least two individuals handle asset custody, authorization, and record keeping, with compensating controls when needed.
