The vast U.S. network of natural gas and hazardous liquid pipelines is integral to U.S. energy supply and has vital links to other critical infrastructure. While an efficient and fundamentally safe means of transport, this network is vulnerable to cyber attacks. In particular, cyber infiltration of supervisory control and data acquisition (SCADA) systems could allow successful hackers to disrupt pipeline service and cause spills, explosions, or firesall from remote locations. In March 2012, the Department of Homeland Security (DHS) reported ongoing cyber intrusions among U.S. natural gas pipeline operators. These intrusions have heightened congressional concern about cybersecurity in the U.S. pipelines sector. The Transportation Security Administration (TSA) is authorized by federal statute to promulgate pipeline physical security and cybersecurity regulations, if necessary, but the agency has not issued such regulations. TSA officials assert that security regulations could be counterproductive because they could establish a general standard below the level of security already in place for many pipelines. An April 2011 White House proposal and the Cybersecurity Act of 2012 (S. 2105) both would mandate cybersecurity regulations for privately owned critical infrastructures sectors like pipelines. A revised version of S. 2105, S. 3414, would permit the issuance of regulations but would focus on voluntary cybersecurity measures. |
