Cybersecurity and Infrastructure Security Agency Guidance


The Cybersecurity and Infrastructure Security Agency (CISA) relies on guidance documents to express and disseminate its views, interpret statutory and regulatory provisions, and implement various programs. Consistent with Executive Order 13891, “Promoting the Rule of Law Through Improved Agency Guidance Documents,” CISA has created this portal to provide information and access to all agency guidance documents on which the agency relies. For the benefit of the public, CISA posts guidance documents to this portal regardless of whether those guidance documents fall within the precise scope of the Executive Order.

We note that many of these documents are also available on other locations on CISA’s website, along with other information regarding CISA’s programs.

We also note that guidance documents generally lack the force and effect of law, unless expressly authorized by statute or incorporated into a contract.
