Blade Runner Redux: Do Embedded Systems Need A Time To Die?

The plot of the 1982 film Blade Runner (loosely based on the 1968 novel Do Androids Dream of Electric Sheep by Philip K Dick) turns on the question of what makes us ‘human.’ Is it memories? Pain? Our ability to feel empathy? Or is it merely the foreknowledge of our own certain demise? In that movie, a group of rebellious, human-like androids – or “replicants” – return to a ruined Earth to seek out their maker. Their objective: find a way to disable an programmed ‘end of life’ in each of them.  In essence: the replicants want to become immortal. It’s a cool idea. And the replicants – pre-loaded with fake memories and histories – pose an interesting philosophical question about what it is that makes us humans. Our artificial intelligence isn’t quite to the ‘replicant’ level yet (the fictional tale takes place in 2019, so we have time). But some […]

Cisco: Internet of Things Tips Scales In Favor Of Bad Guys?

A week from this Wednesday, the Security Ledger is hosting The Security of Things Forum: a day-long event in Cambridge, Massachusetts, that will explore the challenges of securing a global network of hundreds of billions of Internet connected devices. [Register here for The Security of Things Forum – Security and Internet of Things: May 7, Cambridge, MA] One of the big issues that we’ll be tackling is how the Internet of Things (or IoT) changes the security paradigm for enterprises and other large, IT-dependent organizations. Needless to say: the corporate network environment of 2020 won’t bear much resemblance to the network of 2000. But what kinds of tools and technologies will be needed to secure that environment and identify threats to the data stored on it? What security tools and strategies will go the way of the typewriter? What areas will require more investment? So far, the focus of discussions about IoT […]

Heartbleed: Technology Monoculture’s Second Act

Say ‘technology monoculture’ and most people (who don’t look at you cross-eyed or say ‘God bless you!’) will say “Microsoft” or “Windows” or “Microsoft Windows.” That makes sense. Windows still runs on more than 90% of all desktop systems, long after Redmond’s star is rumored to have dimmed next to that of Apple. Microsoft is the poster child for the dangers and benefits of a monoculture. Hardware makers and application developers have a single platform to write to – consumers have confidence that the software and hardware they buy will “just work” so long as they’re running some version of Windows. The downside, of course, is that the Windows monoculture has also been a boon to bad guys, who can tailor exploits to one operating system or associated application (Office, Internet Explorer) and be confident that 9 of 10 systems their malicious software encounters will at least be running some version of the […]

Is Analog The Answer To Cyber Terrorism?

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 […]

RSA Perspective: Outrage With A Side Of Salsa

Let the record show that one of the most dramatic expressions of discontent over rampant government surveillance of U.S. citizens and private companies during last week’s RSA Conference in San Francisco went down at a taco joint. As the world’s cyber security elite gathered in San Francisco’s Moscone Center for the RSA Security Conference, a group of privacy and online rights activists that go by the name “Vegas 2.0” used donated funds to rent out Chevy’s, a popular Mexican food restaurant located next to the exhibit halls and frequented by conference goers. As reported by ZDNet’s Violet Blue, paying RSA attendees and speakers – identifiable by red badges – were refused entry to Chevy’s and handed flyers explaining the protestors’ grievances against the Conference’s parent company, RSA Security, which is alleged to have colluded with the NSA to weaken encryption standards in its products. Among those reported to have been […]
