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 […]

Experts: Despite Warnings, Slow Progress Securing Industrial Systems

January 16, 2014 Paul Roberts

Despite increased media attention to the security of industrial control systems and critical infrastructure, progress in securing those devices has been slow, experts say. Despite progress in some areas, critical infrastructure – including energy and transportation networks- remains vulnerable to attacks leveled at known security holes for months or years because of a lack of vendor response or customers who lack the incentive or know-how to patch vulnerable systems. That according to some of the world’s top experts in cyber security and industrial systems, who are gathering this week at an industry conference in Miami. The S4 Conference, sponsored by the firm DigitalBond, is one of the premiere conferences for cyber security as it pertains to industrial control systems and often coincides with disclosures from industrial system vendors about serious security holes in their products. The security of industrial control systems has been a top concern of IT security experts and government […]

Siemens Patches Holes In Industrial Control Switch

January 9, 2014 Paul Roberts

A security researcher discovered two, serious security holes in a switch by Siemens that could allow an attacker to hijack industrial control system hardware that is heavily used by energy and transportation firms, among others. IOActive, a security consulting firm in Seattle, Washington, said on Thursday that Eireann Leverett, a senior security consultant, discovered two vulnerabilities in Siemens’ SCALANCE X-200 Switches. The vulnerabilities were in a web server component that provided administrators with access to features needed to configure the switches. If exploited, they would have allowed an attacker who had access to the same network as the SCALANCE switch to perform administrative actions on the devices, including updating the switch firmware and hijack active web sessions – all without needing to first log in to the device. SCALANCE is a family of Ethernet switches that connect to industrial control system (ICS) devices including programmable logic controllers (PLCs) and Human […]

Are We Even Trying To Defend The Internet of Things?

January 2, 2014 Paul Roberts

Josh Corman has been a frequent mention on this blog. Josh, who is the Director of Security Intelligence at Akamai Technologies, joined me on the first episodes of Talking Code, speaking about application security and The Internet of Things. He talked candidly about the role that platform security played in his thinking about buying a new car. Well, a few months have passed and now Josh has the new car. But now that he has it, he’s thinking more than ever about the security problem as it pertains to the Internet of Things. In this video, from a TEDx event in Naperville, Illinois (right outside Chicago), Josh talks about his evolving theory of security on the Internet of Things. The IoT, he says, is a “tidal wave” of change that will transform our lives – connecting every aspect of life via software. But this growing amalgam of Internet connected stuff […]

Thingful is a Facebook for Smart Devices

December 16, 2013 Paul Roberts

The data on exactly how many Internet of Things devices will be online by the end of the decade is a matter of debate. Cisco famously put the number at 50 billion by 2020, though Morgan Stanley thinks it could be as high as 75 billion. The analyst firm IDC estimates the number at 50 billion. But others have put the number lower. Gartner puts the number of connected things at around 30 billion by 2020. We might all be better off taking a cue from McDonald’s and just start using the phrase “billions and billions” by the end of the decade. As with McDonald’s hamburgers – the exact number doesn’t really matter, so long as everyone agrees that it’s going to be big. Really big. But all those devices – and the near-limitless IPV6 address space that will accommodate them – do present a management and governance problem: how […]
