From The Washington Post Cybersecurity 202:

I Am The Cavalry’s Josh Corman discussed the changes in the supply chain threat landscape as a result of vaccine distribution with The Washington Post.

Now CISA is working to provide guidance about cybersecurity and physical threats to a wide range of organizations with vastly differing levels of security. Because vaccine distribution protocols vary from state to state, CISA’s playbook is always evolving with changes in those procedures, says Corman.
