Using UDP in Internet of Things Devices I recently read this article by John Carbone about using UDP in embedded systems. The advice in the article is accurate, but there are some other issues to consider when designing UDP based protocols in embedded systems that Carbone did not address. I wanted to tackle them here. First and foremost: UDP datagrams are trivial… View Article
Thoughts on Streaming Video Securely The kind folks at EDN have asked Cardinal Peak to author an occasional blog about streaming video. The first post went live this morning and discusses streaming video securely: Until recently, the accepted wisdom in the industry was that end users didn’t care about encrypting this type of video, as long as it was a… View Article
More Thoughts on Security and the Internet of Things Attacks that are initially restricted to the realm of esoteric, government-backed spooks become accessible over time to run-of-the-mill cybercriminals. Take, for example, the Linux.Darlloz worm, which attacks embedded devices and is interesting for a couple of reasons. First, it propagates by exploiting a vulnerability that was patched in May 2012. But the firmware images on many embedded devices are much older than that. The second reason I find it particularly interesting is it targets PHP, a scripting language largely used for web development.
Five Software Tips for Securing IoT Devices I’ve got a new blog post up today at EE Times, discussing how to secure devices on the Internet of Things: It used to be academically interesting, perhaps, that an attacker could compromise an unconnected home thermostat. Today, it’s another thing entirely that an attacker can potentially target thousands of home thermostats from afar, determine… View Article
How To Find a Memory Leak Finding memory leaks and other problems in your code can be challenging, but there are tools available to help simplify that process. Remember to add time to your schedule so that you can apply the available tools for finding memory leaks and other problems.
IACP Product Introduction I just spent the last three days at the IACP show in Denver — the annual conference and expo for the International Association of Chiefs of Police. For anyone who was once a 12-year-old boy, IACP is about as cool as it comes because there are all sorts of cop paraphernalia on display — from… View Article
