What Should You Spend on Cybersecurity?

By PRICE® SystemsMay 19, 2021

Updated Life Cycle Cost Estimating Factors for Cybersecurity in Business IT Systems

Starting in 2019, analysts from PRICE Systems, LLC and The Mitre Corporation conducted joint research to identify cybersecurity data and estimating methods to support the development of government IT programs.  We downloaded data from the OMB IT Dashboard to use for the analysis.  In 2020, we presented a set of initial factors that support system development cost estimates.  These factors estimate cybersecurity cost by cost category as a percent of Total Investment Cost for an IT system.  Categories included cyber program management, test, documentation, certification, design, requirements analysis, risk assessment, hardware applications and software applications.

Over the last year, PRICE® has continued their portion of the research, using updated data from the OMB IT Dashboard, expanded to now also include sustainment costs for IT systems.  We added additional sustainment categories (Manage Cyber Ops, Recurring ATO, SW Maintenance, SW Patches, HW Maintenance), and revised the 2020 factors to reflect additional activities and programs.  The revised factors for Development and Sustainment will be presented as part of the webinar, along with the statistical validation of their ability to provide defensible estimates of cybersecurity costs.  PRICE® will be applying these factors to our common element models to add cybersecurity costs for program management, systems engineering, test, data and integration in support of IT systems development and operations.
