Name the DHS sector-specific agency responsible for cybersecurity in the chemical sector.

The Cybersecurity and Infrastructure Security Agency (CISA) is the DHS sector-specific agency responsible for cybersecurity in the chemical sector. While CISA has overall responsibility for national cybersecurity and infrastructure protection, it works with other agencies and sector-specific agencies (SSAs) to address the unique risks of individual sectors. CISA coordinates with the Environmental Protection Agency (EPA) on chemical sector security issues, but CISA has the lead role for cybersecurity risk management in this critical infrastructure sector.
