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 […]

Unknown Knowns: Arbor Warns Of Widespread Point of Sale Compromises

The hack of U.S. retailer Target put attacks on point of sale systems on the radar, and prompted major retailers to revisit the security of the systems that accept credit card transactions. Now research from Arbor Networks is warning that hackers and cyber criminals are doubling down on point of sale (PoS) systems with a wide range of specialized PoS malware and targeted attacks. Arbor says it has data suggesting that PoS compromises may be widespread, and undetected. Arbor’s Security Engineering & Response Team (SERT)  issued its findings in a Threat Intelligence Brief (2014-6)  report. The company said that “ambitious threat actors” are using targeted attack campaigns against PoS networks. The “longevity and extent” of PoS attack campaigns – even at wealthy and sophisticated organizations – is “a serious concern.”   [Read Security Ledger’s coverage of the Target data breach here.] “In organizations with security teams and well-managed network infrastructure, point of […]

IDS And The IoT: Snort Creator Marty Roesch On Securing The Internet of Things

Martin Roesch is one of the giants of the security industry: a hacker in the truest sense of the term who, in the late 1990s created a wide range of security tools as a way to teach himself about information security. One of them, the open source SNORT intrusion detection system, turned into one of the mostly widely used and respected security tools in the world. SNORT became the foundation for Sourcefire, the company Marty helped found in 2001. And Sourcefire went on to fantastic success: first as a startup, then as a publicly traded company and, as of October of last year, as part of Cisco Systems, after the networking giant bought Roesch’s company for $2.7 billion. These days, Marty serves as a Vice President and Chief Architect of Cisco’s Security Business Group, where he’s helping shape that company’s strategy for securing the next generation of enterprise (and post-enterprise) networks.

Cisco Eyes Security Services For Connected Cars

Connected vehicles are a big new area of investment. We saw evidence of that at the recent Consumer Electronics Show (CES) and we’re  hearing a lot more about it this week, as carmakers strut their stuff at the North American International Auto Show.   Security isn’t generally part of the conversation, but as we’ve noted here on more than one occasion: connected vehicles introduce a myriad of challenging security problems, from authentication to communications and system integrity, not to mention data privacy. [Read more Security Ledger coverage of connected vehicles here.] Now networking giant Cisco says that it sees a role for its technology in protecting vehicle area networks (VANs), just as the company’s networking equipment enabled and protected local and wide area networks (LANs and WANs) over the last two decades. In a blog post, Cisco said it is rolling out “a range of products and services” that it […]

Week In Security: More Target Woes and CES

It was another eventful week in security, with another big revelation in the story of a hack of box retailer Target Inc. That update – which accompanied Target’s fourth quarter earnings guidance – nearly doubled the number of known victims of that attack. It also revealed that credit card data was not the only information stolen by hackers, who also made off with customer names, mailing addresses and emails. In this latest installment of Security Ledger’s Security Week in Review, we spoke with Jody Brazil, the President of the security firm FireMon about the week’s events. Jody is a seasoned security professional who works day-in-day-out with companies that are trying to manage their risk. He said that even large companies like Target can fall victim to sophisticated attacks, but the IT security may be too quick to give up on traditional defensive technologies. Jody and I had an interesting chat about […]
