In April 2024, HUD OIG met with HUD OCIO to discuss progress and requirements for closure of this recommendation. In addition, OIG reviewed this recommendation as part of the annual FY 2024 FISMA evaluation in April 2024 and learned from HUD OCIO that that there would be a procedure update that would implement the ingestion and monitoring of all inbound and outbound traffic. The OIG requested to be provided with these procedures when finalized and evidence of implementation on May 1, 2024.
Corrective Action Taken
HUD OCIO updated its Cybersecurity Incident Response Plan and developed more detection and protection mechanisms to monitor network traffic in its IT environment. These mechanisms include anti-malware agents, data loss prevention, endpoint detection and response, firewalls, and intrusion detection and prevention systems. HUD’s SOC also developed standard operating procedures and playbooks for abnormal traffic alerts triggered by the above tools that are posted internally for SOC personnel to utilize. Addressing this recommendation resulted in improvement of HUD’s networking monitoring process by enhancing visibility into network traffic. It also increased HUD’s incident response program capabilities by ensuring that HUD has a plan to monitor traffic and better detect and respond to security incidents. As part of our regular Federal Information Security Act of 2014 (FISMA) assessments, HUD OIG will continue to assess HUD’s incident response effectiveness and threat detection to ensure HUD addresses new and evolving threats.
