In June, the White House issued National Security Presidential Memorandum 12 (NSPM-12) which restructures cybersecurity governance of the national security systems (NSS) that federal agencies use to store, process and share classified national security material. The memo directs some significant changes that will affect agencies’ operating reality, although the implications may be challenging to discern. One is the 1990 presidential National Security Directive 42, which established the organization now known as the CNSS. NSPM-12 retains the National Security Administration’s (NSA) original designation as the CNSS technical advisor and group member, while transferring the agency’s leadership role to a member of the National Security Council, which is chaired by the president. The other rescinded policy is the 2022 National Security Memorandum 8 (NSM-8).
