A security practitioner completes a vulnerability assessment on a company’s network and finds several vulnerabilities, which the operations team remediates. Which of the following should be done next?

After vulnerabilities are remediated, rescanning the network is the crucial next step to verify that the patches or changes were effective and did not introduce new issues. This ensures the vulnerabilities are truly closed. Conducting an audit (A) is a broader, more formal review of security controls and compliance, which might happen later but isn't the immediate verification step. Initiating a penetration test (B) is a more aggressive, hands-on attempt to exploit vulnerabilities; it's typically done after initial remediation and rescanning to confirm robust security. Submitting a report (D) is important, but it should be done after verifying the remediation's success through a rescan, as the report needs to reflect the current security posture.
