In the office, auditors have a dedicated workspace equipped with the necessary tools and resources to conduct audits effectively. This includes access to computer systems, audit software, documentation, and communication tools.

This could involve visiting different sites, such as branch offices, data centers, or third-party vendor locations. Travel requirements vary, from occasional local visits to extensive travel for audits conducted across multiple regions or countries. Travel enables auditors to physically assess security controls, validate information, and conduct in-person interviews, ensuring a comprehensive evaluation of security practices.
