To find possible avenues of entry for hackers, it evaluates how well an organization’s security measures such as firewalls, intrusion detection systems, and access controls are working.
- Risk Assessment Audits: Information security audits also include risk evaluations. The primary intention of risk assessments is to detect possible hazards and evaluate the probability of such dangers becoming actual. To detect and evaluate the risks of significant misstatement, whether as a result of fraud or mistake, we carry out risk assessment methods to get a knowledge of the entity and its environment, including the firm’s controls.
