IoT Security – We’re Doing it Wrong

I spend a lot of time at information security industry events. It’s part of my job at Cisco -visiting customers and attending and speaking at conferences. And these days, many of my conversations are focused on issues surrounding securing the Internet of Things. By and large, I enjoy this immensely. But my experience also gives me a vantage point from which to observe the cyber security and IoT security community broadly. What I’ve concluded is this: ours is a community that is made up of highly gifted and intelligent professionals with diverse, but also specialized skills. Unfortunately, ours has been – and continues to be- an insular community. I’ve come to realize that this pronounced and endemic navel gazing does us and the general public a great disservice. In fact, it may make the job of not repeating the security mistakes of the last two decades more difficult. Can we […]

Popular Web Sites Still Getting Gamed in SEO Attacks

In this post, Security Ledger contributor Or Katz of Akamai provides details of how malicious actors are abusing redirect vulnerabilities in popular web sites to boost the reputation of malicious sites they control. One recent attack involved the compromise of some 4,000 vulnerable web applications for the purpose of pumping up the search engine ranking of more than 10,000 malicious web sites, Katz reveals.

Black Hat 2014

New Calls For A Common Hardware Vulnerability Database At Black Hat

The Black Hat briefings made its reputation as a forum for star security researchers to unveil hair raising vulnerabilities in hardware and software. But Black Hat has become a more corporate event and collaboration is much in evidence these days. The latest example: the first roundtable discussion ever held at Black Hat. Speaking on Wednesday, Don Bailey, CEO of Lab Mouse Security, and Zach Lanier, Senior Security Researcher at Duo, facilitated a lively discussion of embedded system security before a group of attendees arranged around a table with a few more chairs off to the side. Bailey asked the audience to start the conversation, and he and Lanier then moderated the discussion. The conversation started with discussion of new secure chipsets, such as ARM TrustZone, and the fact that few institutions are using them. One factor is cost. Some organizations are gravitating toward open source chipsets such as Ardinuio, which […]

Phishing

TRUST: Threat Reduction via Understanding Subjective Treatment

It has become obvious (to me, anyway) that spam, phishing, and malicious software are not going away. Rather, their evolution (e.g. phishing-to-spear phishing) has made it easier to penetrate business networks and increase the precision of such attacks. Yet we still apply the same basic technology such as bayesian spam filters and blacklists to keep the human at the keyboard from unintentionally letting these miscreants onto our networks. Ten years ago, as spam and phishing were exploding, the information security industry offered multiple solutions to this hard problem. A decade later, the solutions remain: SPF (Sender Policy Framework), DKIM (Domain Keys Identified Mail) and DMARC (Domain-based Message Authentication, Reporting & Conformance). Still: we find ourselves still behind the threat, rather than ahead of it. Do we have the right perspective on this? I wonder. The question commonly today is: “How do we identify the lie?” But as machine learning and data science become the new norm, I’m […]

Dan Geer Keynote: Security of Things Forum

The following is a transcript of a speech given by Dr. Dan Geer at the Security of Things Forum on May 7, 2014. The Forum was held at The Sheraton Commander in Cambridge, Massachusetts. The official copy of Dr. Geer’s speech lives on his web site, and can be found here. .Security of Things .Dan Geer, 7 May 14, Cambridge Thank you for your invitation and to the other speakers for their viewpoints and for the shared experience. With respect to this elephant, each of us is one of those twelve blind men. We are at the knee of the curve for deployment of a different model of computation. We’ve had two decades where, in round numbers, laboratories gave us twice the computing for constant dollars every 18 months, twice the disk drive storage capacity for constant dollars every 12 months, and twice the network speed for constant dollars every […]
