Review of Medicare Administrative Contractor Information Security Program Evaluations for Fiscal Year 2019

Why OIG Did This Review

The Social Security Act requires that each Medicare administrative contractor (MAC) have its information security program evaluated annually by an independent entity. The Centers for Medicare & Medicaid Services (CMS) contracted with Guidehouse, LLP (Guidehouse), to evaluate information security programs at the MACs, using a set of agreed-upon procedures (AUPs). HHS OIG must submit to Congress annual reports on the results of these evaluations, to include assessments of their scope and sufficiency. This report fulfills that responsibility for fiscal year 2019.

Our objectives were to assess the scope and sufficiency of MAC information security program evaluations and report the results of those evaluations.

How OIG Did This Review

We reviewed Guidehouse's working papers to determine whether Guidehouse sufficiently addressed all areas required by the AUPs. We also determined whether all security-related weaknesses were included in the Guidehouse reports by comparing supporting documentation with the reports. We determined whether all gaps in the Guidehouse reports were adequately supported by comparing the reports with the Guidehouse working papers.

What OIG Found

Guidehouse's evaluations of the contractor information security programs were adequate in scope and sufficiency. Guidehouse reported a total of 125 gaps at the 7 MACs for FY 2019, which was 12 percent more than the number of gaps for the same 7 contractors in FY 2018. The increase was due in part to the addition of database and web server testing. Deficiencies remained in each of the nine Federal Information Security Modernization Act of 2014 control areas that were tested. CMS should continue its oversight visits and ensure that the MACs remediate all gaps to improve the MACs' information technology security.
