Federal Reports

The VA Office of Inspector General’s information security inspection program assesses whether VA facilities are meeting federal security requirements related to three control areas the OIG determined to be at highest risk: configuration management controls, security management controls, and access controls. For this inspection, the OIG selected the Battle Creek Healthcare System in Michigan. The OIG found deficiencies in all three areas inspected.

Configuration management controls, which identify and manage security features for all hardware and software components of an information system, were deficient in vulnerability remediation, system baseline configurations, and unauthorized software remediation.

Security management controls had one deficiency. The OIG found biomedical staff relied on incomplete security remediation reports to manage vulnerabilities on medical devices. The inspection team identified 25 vulnerabilities on seven biomedical devices that were not tracked in security remediation reports used by biomedical staff.

Access controls had three deficiencies. The OIG found the Battle Creek facility was deficient in physical access, environmental controls, and network segmentation. As a result, the facility risks unauthorized access, disruption, and destruction of critical information technology resources.

The OIG made three recommendations to the assistant secretary for information and technology and chief information officer to improve vulnerability management processes, implement a more effective baseline configuration process, and improve the remediations reporting process for the Continuous Readiness in Information Security Program. The OIG also made three recommendations to the healthcare system’s director, in conjunction with the assistant secretary for information and technology and chief information officer, to implement improved physical access controls, ensure network segmentation controls are applied as appropriate, and implement improved, consistent environmental controls for network communications closets.

Why We Did This Report

The U.S. Environmental Protection Agency Office of Inspector General conducted this audit to determine whether the EPA has established sufficient controls to prevent unauthorized access to the Central Data Exchange system.

Summary of Findings

The EPA needs to strengthen management and access security controls for the Central Data Exchange, or CDX, system. The security of the CDX system is integral to the EPA accepting electronic environmental data for the Agency’s air, water, hazardous waste, and toxics release inventory programs. Without adequate security controls, the CDX is vulnerable to threat actors exploiting weak security controls to potentially gain unauthorized access, create fraudulent accounts, and enter unreliable data into the system.
