Presidential Policy Directive 20 (PPD 20)
PPD 20 provides a framework for US cyber security by establishing principles and processes. Started in 2012, this directive supersedes National Security Presidential Directive NSPD-38.
The directive complements NSPD-54/Homeland Security Presidential Directive HSPD-23.
This directive pertains to cyber operations, including those that support or enable kinetic, information, or other types of operations.
Most of this directive is directed exclusively to defensive and offensive cyber effects operations: DCEO and OCEO.
National Security Presidential Directive 54 (NSPD 54)
Started in 2008, NSPD 54 was issued concurrently as Homeland Security Presidential Directive 23.

It empowers DHS to lead and coordinate the national cyber security effort to protect cyberspace and the computers connected to it.
The directive contains the Comprehensive National Cybersecurity Initiative (CNCI), (EPIC 2018).
