The Cybersecurity and Infrastructure Security Agency (CISA) published a blog, Lessons Learned from CISA’s incident, to share experiences from recent response activities. Sharing experiences from incident response activities help other organizations learn from such experiences and enables them to take necessary precautions to prevent similar incidents from happening in their environments. For the Healthcare and Public Health (HPH) sector, these incidents highlight the urgent need for stringent third-party risk management, comprehensive incident playbooks, and rapid vulnerability patching
On May 15, CISA began an internal incident response when an investigative reporter inquired about internal CISA Amazon AWS GovCloud Keys and other information being made available in a public repository. CISA’s Office of the Chief Information Officer (OCIO) took swift and comprehensive action to mitigate any exposure to CISA’s cloud resources and code repositories including:
- Eliminate public exposure and prevent further harm
- Analysis of public repository, associated cybersecurity telemetry and log files
- Implement correction actions
