Is Analog The Answer To Cyber Terrorism?

March 17, 2014 Paul Roberts

Ralph Langner is one of the foremost experts on the security of critical infrastructure that we have. So, generally, when Ralph says something – whether its about Stuxnet, or cyberwar or the security of nuclear power plants – folks listen. And these days, Ralph is wondering, out loud, whether our reliance on digital systems to manage critical infrastructure has gone too far. The answer, he suggests, may be to go “back to the future,” as it were: reintroducing analog systems into the control process chain as a backstop for cyber attacks. Case in point: the Department of Homeland Security’s ICS-CERT warned on Friday that firmware for Siemens SIMATIC S7-1500 CPUs (Central Processing Units) contain nine vulnerabilities that could enable attacks such as cross site request forgery, cross site scripting and URL redirection. (Siemens has issued a firmware update that patches the holes.) Langner is among the world’s foremost experts on […]

FDA Will Regulate Some Apps As Medical Devices

September 24, 2013 Paul Roberts

In an important move, the U.S. Food And Drug Administration (FDA) has released final guidance to mobile application developers that are creating medical applications to run on devices like the iPhone and Android mobile devices. Some applications, it said, will be treated with the same scrutiny as traditional medical devices.* The statement is the final word from the FDA on the approach it will take when enforcing federal regulations regarding the safety of medical devices to the large and fast-growing category of medical applications. The agency said on Monday that, while it doesn’t see the need to vet “the majority of mobile apps,” because they pose “minimal risk to consumers,” it will exercise oversight of mobile medical applications that are accessories to regulated medical devices, or that transform a mobile device into a regulated medical device. In those cases, the FDA said that mobile applications will be assessed “using the same […]

Report: Crematoriums To Caterpillars Shodan Reveals Internet Of Things

September 9, 2013 Paul Roberts

What kind of stuff is lurking out there on the vast (and growing) Internet of Things? A recent story in Forbes makes the point that its a lot more varied than you might think – everything from Caterpillar trucks to public school classrooms to a crematorium. And “yes,” I said “crematorium.” The idea that surveillance cameras can be accessed from the public Internet isn’t really new. Security researchers have been showing off ways to sidestep security features for IP enabled surveillance cameras for years. We wrote last week about the Federal Trade Commission’s case against a California company, TRENDNet, which made a line of balky, in secure home surveillance gear. But Kashmir Hill makes the point in her story that surveillance cameras are just the tip of the iceberg. Hill interviewed security researchers and professional Shodan jockeys, who use that hardware focused search engine to uncover supposedly secure equipment and industrial control […]

U.S. Cyber Security Framework Is Good News-For Hackers

September 4, 2013 Paul Roberts

Ralph Langner, the renowned expert on the security of industrial control- and SCADA systems, warns that the latest draft of the U.S. Government’s Cyber Security Framework (CSF) will do little to make critical infrastructure more resistant to devastating cyber attacks. Writing on his blog, Langner said that a draft of the National Institute of Standards and Technology’s (NIST’s) Preliminary Cybersecurity Framework does little to compel critical infrastructure owners to improve the security of their systems, or guarantee uniform (and robust) cyber security standards in the critical infrastructure space. NIST released the latest draft of the CSF late last month (PDF). But Langner, writing on Wednesday, likened the framework to a recipe that, if used by three different chefs, produces three totally different dishes…or just a messy kitchen. “A less metaphorical words, a fundamental problem of the CSF is that it is not a method that, if applied properly, would lead to predictable results,” […]

NIST Cyber Security Draft Framework Puts Execs In Driver’s Seat

July 3, 2013 Paul Roberts

The U.S. government’s federal technology agency has published a draft version of a voluntary framework it hopes will guide the private sector in reducing the risk of cyber attacks on critical infrastructure. The National Institute of Standards and Technology (NIST) published a draft of its Preliminary Framework to Reduce Cyber Risks to Critical Infrastructure on Monday. The document provides a guide for critical infrastructure owners of different maturity levels to begin documenting and understanding their risk of cyber attack, and – eventually – to measure their performance in areas such as asset management, threat detection and incident response. The framework was called for by Executive Order 13636, signed by President Obama in February. In that order, NIST was charged with creating a framework for sharing cyber security threat information and information on successful approaches to reduce risks to critical infrastructure. The Framework is comprised of five major cybersecurity functions: Know […]
