Updating old IT systems can cost time and money in addition to disrupting work continuity. To remediate this issue on the Federal level, Congress appropriated $100 million for the Technology Modernization Fund to allow updating of aging systems. The main force behind modernization is the increased need for cybersecurity.
A study by the Fox School of Business at Temple University and the McCombs School of Business at the University of Texas-Austin determined that a one percent increase in new IT development spending results in a five percent decrease in breaches.
Modernization on any level must be approached with care because new systems generally incorporate advanced security technologies that may not be compatible with currently operating solutions, leaving new entry points for hackers. Additionally, a well conceived strategic approach to modernization would help prevent new attacks.
