Initially, the agency announced plans to hire approximately 250 new employees to fill critical vacancies in cybersecurity, infrastructure security, and emergency communications. This recruitment is part of a broader goal to expand the workforce by roughly 600 people. Alongside this expansion, CISA partnered with the FBI and international agencies from Australia, Canada, New Zealand, and the United Kingdom to issue guidance on maintaining transparency and accountability during IT and operational technology outages. Subsequently, CISA released an Insider Threat Mitigation Guide designed to assist critical infrastructure operators in defending against sabotage, data theft, and cyberattacks. The guide provides frameworks and best practices to protect sensitive data and key assets, citing historical economic losses caused by employee theft of proprietary information. ## Timeline ### 2026-09-10: CISA releases guide to mitigate insider threats in critical infrastructure CISA has released a new Insider Threat Mitigation Guide to help critical infrastructure organizations defend against data theft, sabotage, and evolving cyber threats. 2 sources. https://clstr.news/cluster/cisa-releases-guide-to-mitigate-insider-threats-in-critical-infrastructure ### 2026-09-08: CISA expands workforce and issues international outage communication guidance CISA is hiring hundreds of new employees to bolster cybersecurity capabilities while partnering with international agencies to issue new guidance on communicating during critical IT and operational outages. 2 sources. https://clstr.news/cluster/cisa-expands-workforce-and-issues-international-outage-communication-guidance --- Cite as: CISA infrastructure security and workforce initiatives.
