The Office of Information Security

Our Mission

The mission of the Office of Information Security (OIS) is to provide leadership in the development, delivery, and maintenance of an information security program by safeguarding the state's information assets against unauthorized use, disclosure, modification, damage, or loss to support Colorado’s mission to provide secure and sustainable services.

OIS is directly aligned with the goals and objectives of the National Strategy to Secure Cyberspace. Working closely with federal, state, local, and private sector partners, the Office of Information Security actively gathers and analyzes information on cyber threats and vulnerabilities that present risk to the state's information systems or the critical information managed within.
