3. Additional cyber guidance from the government
In addition to the EO and the IIJA legislation, multiple government agencies have been issuing cyber guidance to help organizations improve their cyber posture by providing frameworks, architectures, maturity models and strategy documents to provide support.
For example, DHS CISA issued the Zero Trust Maturity Model for agencies to reference as they transition toward a Zero Trust architecture. In addition, DHS issued the Cloud Security Technical Reference Architecture to illustrate recommended approaches to cloud migration and data protection (as outlined in Section 3(c)(ii) of EO 14028). Furthermore, the Office of Management and Budget (OMB) published the Federal Zero Trust Strategy designed to move the US government toward a Zero Trust architecture.
EY professionals have worked with organizations like the Information Technology Industry Council (ITI) to provide recommendations about the new guidance. View the ITI Summary and ITI Full Whitepaper.
In addition to published guidance, DHS established the Joint Cyber Defense Collaborative (JCDC) in July 2021 to bring together public and private sector entities to unify deliberate and crisis action planning while coordinating the integrated execution of these plans.
