So far, authorities have detected software tools that could be used to destroy components of the electrical infrastructure. Meanwhile, cyberspies could also target other systems, such as water, sewage and others, with the intention of causing a major infrastructure disruption or collapse.
However, steps are being taken to remediate the problem. The strength and security of the U.S. cybersystems, which control components of the electrical grid, are now undergoing extensive scrutiny under a comprehensive cybersecurity review, ordered by President Barack Obama, scheduled for completion next week.
Congress is also weighing in on a cybersecurity bill that proposes widespread changes to the governing policies that oversee and protect the U.S. computer network infrastructure, including the appointment of a cybersecurity czar. Among other things, the legislation, developed by Senate Commerce Committee Chairman John Rockefeller IV, D-W. Va. and Sen. Olympia Snowe, R-Maine, cultivates the relationship between government and the private sector in regards to cybersecurity, and gives the federal government the authority to disconnect federal or critical infrastructure from the Internet if it was believed to be susceptible to a cyberattack.
Previously, the Bush administration had approved $17 billion in secret funds to protect government networks, according to the Journal.
Security experts say that the reported cyberespionage incident on the U.S. electrical grid underscores the inherent vulnerabilities and the copious security problems created when systems are linked to the Internet.
Paul Ferguson, senior threat researcher for security company Trend Micro, said that any kind of attack on infrastructure would be “pretty damn bad.”
“If you’re going to connect sensitive networks to the Internet, you’re going to expose yourself to security problems,” he said. “That same type of spyware and malware now can also ensnare any other systems linked to the Internet as well.”
“I would hate to think a machine that was used to manage infrastructure could be accessed by persons unknown in a foreign or hostile country,” he added.
The recent attack on the U.S. electrical grid is not the first time that hackers have leveraged infrastructure in cyberattacks. Last year, CIA analyst Tom Donahue told attendees at a power-industry conference that cyberattacks have occurred on “multiple regions outside the United States,” according to Reuters.
Meanwhile, Trend Micro’s Ferguson said that he and other Cyber Security professionals have consistently warned authorities and officials for years about the myriad potential threats created when infrastructure is controlled remotely over the Internet, but said that warnings often went unheeded in an effort to cut costs.
“What we’ve got here is people making business decisions in the name of cost efficiency, and adding additional risk at the security level,” Ferguson said. “Those bad business decisions based on costs may come back to haunt them.”
In addition, the North American Electric Reliability Corp. (NERC) issued a letter Tuesday warning the public of inherent and inevitable problems that occur when infrastructure can be operated through cyberspace.
“But as we consider cybersecurity, a host of new considerations arise,” said Michael Assante, chief security operator for NERC, in the letter. “One of the more significant elements of a cyberthreat, contributing to the uniqueness of cyber-risk, is the cross-cutting and horizontal nature of networked technology that provides the means for an intelligent cyberattacker to impact multiple assets at once, and from a distance.”
In his letter, Assante called for a “fresh, comprehensive” look at new and innovative risk-based approaches that consider the potential consequences of an attack resulting in “potential misuse” of “the entire interconnected system.”
“Taking this one step further, we as an industry, must also consider the effect that the loss of that [electrical] substation, or an attack resulting in the concurrent loss of multiple facilities, or its malicious operation, could have on the generation connected to it,” he said.
Cyber Security channel partners also contend that an infrastructural attack that destroys the power grid or contaminates the water supply is a very real threat.
“Just to penetrate a network is not rocket science any more. We need rocket scientists to prevent [attackers] from doing destructive things,” said Tim Carney, CEO of Fremont, Calif.-based NetworkGuys. “The good news is, we have people who realize that.”
