A new report states that the nation’s electric grid remains highly vulnerable to attacks from Iran and North Korea, or other threats like geomagnetic storms from solar activity.
The report, titled “Electric Grid Vulnerability: Industry Responses Reveal Security Gaps,” released by Reps. Ed Markey (D-Mass.) and Henry A. Waxman (D-Calif.), indicates that the industry-driven process by which grid security standards are set results in long delays and haphazard implementation of the voluntary security recommendations the industry refuses to make mandatory.
In January, Reps. Markey and Waxman sent letters to more than 150 utilities asking how often the grid came under attack, what measures the utilities were taking to protect against cyber attacks like the Stuxnet computer worm, and other questions.
The top findings of the report include:
· The electric grid is the target of numerous and daily cyber attacks. One utility said that there were 10,000 attempted attacks each month, and others describe the level of potential incursions as “daily,” “constant,” “malicious,” and “seeking to gain access to internal systems.”
· Most utilities comply with mandatory standards only, not additional voluntary ones, and do so unevenly. For example, while almost all utilities said they complied with mandatory Stuxnet standards, only 21 percent of industry-owned utilities, 44 percent of municipally- or cooperatively-owned utilities and 62.5 percent of federal entities reported compliance with voluntary Stuxnet recommendations that industry did not agree to mandate.
· Most utilities have not taken concrete steps to reduce the vulnerability of the grid to geomagnetic storms and it is unclear whether the number of available spare transformers is adequate.
“National security experts say that cyber attacks on America’s electric grid top the target list for terrorists and rogue states, yet we remain highly vulnerable to attacks,” said Rep. Markey, a senior member of the Energy and Commerce Committee. “We need to push electric utilities to enlist all of the measures they can now, and push for stronger standards in Congress that will keep our economy and our country safe from cyber warfare.”
“The electric grid is vital to our economy and national security,” said Rep. Waxman, ranking member of the Energy and Commerce Committee. “The utility responses are sobering. They reveal serious gaps in the security of our electric grid and Congress needs to address these gaps in a bipartisan way.”
