CISA’s Greenfield Solution: A Model for IT Modernization in the Zero-Trust Era
Summary
There are too many updates, patches and critical fixes to tackle — all to maintain systems that likely don’t offer the power or agility required to run more innovative solutions. Enter the “greenfield” approach, which allows agencies to regain control and build new environments free of legacy code while dramatically reducing their attack surface. The Cybersecurity and Infrastructure Security Agency embraced the greenfield option, undertaking a large-scale modernization that will replace most legacy IT systems with a brand-new environment, both in the cloud and (where necessary) on-premises. Rather than struggle to sustain and secure decades-old systems, CISA is building an environment free from many of the old vulnerabilities and historical design decisions that bad actors are most likely to try to exploit. Our workshops, assessments and deep understanding of industry best practices can assist IT leaders with demonstrating the value of modernization, implementing an agile approach and tackling technical debt in small, manageable steps.
