 <title>Critical Infrastructure Protection: Multiple Efforts to Secure Control Systems Are Under Way, but Challenges Remain</title>
</titleInfo>
<abstract>Control systems--computer-based systems that monitor and control
sensitive processes--perform vital functions in many of our	 
nation&apos;s critical infrastructures such as electric power	 
generation, transmission, and distribution; oil and gas refining;
and water treatment and distribution. The disruption of control  
systems could have a significant impact on public health and	 
safety, which makes securing them a national priority. GAO was	 
asked to testify on portions of its report on control systems	 
security being released today. This testimony summarizes the	 
cyber threats, vulnerabilities, and the potential impact of	 
attacks on control systems; identifies private sector		 
initiatives; and assesses the adequacy of public sector 	 
initiatives to strengthen the cyber security of control systems. 
To address these objectives, GAO met with federal and private	 
sector officials to identify risks, initiatives, and challenges. 
GAO also compared agency plans to best practices for securing	 
critical infrastructures.</abstract>
