Information Technology: Agencies Need to Develop and Implement Modernization Plans for Critical Legacy Systems, Statement of Kevin Walsh, Director, Information Technology and Cybersecurity, Testimony Before the Subcommittee on Emerging Threats and Spending Oversight, Committee on Homeland Security and Governmental Affairs, U.S. Senate   [open pdf - 446KB]

From the Highlights: "Each year, the federal government spends more than $100 billion on IT [information technology] and cyber-related investments. Of this amount, agencies have typically spent about 80 percent on the operations and maintenance of existing IT investments, including legacy systems. However, federal legacy systems are becoming increasingly obsolete. In May 2016, GAO [Government Accountability Office] reported instances where agencies were using systems that had components that were at least 50 years old or the vendors were no longer providing support for hardware or software. Similarly, in June 2019 GAO reported that several of the federal government's most critical legacy systems used outdated languages, had unsupported hardware and software, and were operating with known security vulnerabilities. GAO was asked to testify on its June 2019 report on federal agencies' legacy systems. Specifically, GAO summarized (1) the critical federal legacy systems that we identified as most in need of modernization and (2) its evaluation of agencies' plans for modernizing them. GAO also provided updated information regarding agencies' implementation of its related recommendations."
