If an IS audit reveals that an organization is not proactively addressing known vulnerabilities, the IS auditor should recommend that the organization assess the security risks to the business first, as this would help to prioritize the vulnerabilities based on their impact and likelihood, and determine the appropriate mitigation strategies. Verifying the disaster recovery plan (DRP) has been tested, ensuring the intrusion prevention system (IPS) is effective, and confirming the incident response team understands the issue are important steps, but they are not as urgent as assessing the security risks to the business.
