Several on KRACK

Three articles of interest on the new WiFi KRACK—

This is not a crypto bug but a protocol bug (a pretty obvious and trivial protocol bug). When a client connects to the network, the access-point will at some point send a random “key” data to use for encryption. Because this packet may be lost in transmission, it can be repeated many times. What the hacker does is just repeatedly sends this packet, potentially hours later. Each time it does so, it resets the “keystream” back to the starting conditions. The obvious patch that device vendors will make is to only accept the first such packet it receives, ignore all the duplicates. —Robert Graham @Errata Security

So this is essentially a replay attack—something that is not taken seriously enough in the security world, by and large.

Researchers this week published information about a newfound, serious weakness in WPA2 — the security standard that protects all modern Wi-Fi networks. What follows is a short rundown on what exactly is at stake here, who’s most at-risk from this vulnerability, and what organizations and individuals can do about it. —Krebs on Security

And, finally, an article on protecting your network from KRACK—

Tempered Networks extends Bring Your Own Network across the enterprise

Remember when Bring Your Own Device (BYOD) was all the rage? That’s the concept of workers being able to bring their own mobile phones and tablets into the workplace and use them for business-related functions. That quickly evolved into bring your own applications, where workers or lines of business would go get their own apps via the cloud.Also on Network World: 7 must-have network tools So, what else can non-technical people go get on their own? How about a network? That may seem a bit farfetched, as I’ve never seen an application developer bring a router into the office. But that’s exactly what Tempered Networks is enabling with the introduction of Bring Your Own Network (BYON). To read this article in full or to leave a comment, please click here

Cumulus Networks inducted into JPMorgan Chase Hall of Innovation

Roll out the red carpet and get your acceptance speech ready — no, Rocket Turtle hasn’t won an Oscar (yet), but we do have some exciting news. Cumulus Networks is happy to announce that we have been inducted into the JPMorgan Chase Hall of Innovation, which recognizes select emerging tech companies for their innovation, business value and disruptive nature. The Hall of Innovation Award was presented at the 9th Annual J.P. Morgan Technology Innovation Symposium in Menlo Park, California.

Cumulus Networks has received this honor after providing JPMorgan Chase with our NOS Cumulus Linux. In fact, Cumulus Networks is currently the networking standard for Gaia, JPMorgan Chase’s private cloud, and is also pursuing other use cases within the firm. Matthew Liste, Head of Cloud Engineering, stated that “Cumulus Networks has helped the firm reduce capital expenditures, optimize data center network costs, and bring infrastructure to the market faster.” That’s the power of web-scale networking!

When asked for comment about our partnership with JPMorgan Chase, our fearless leader and CEO Josh Leslie had this to say: “For a company with the size and reputation of JPMorgan Chase, it is critical that the network operates with efficiency to keep the Continue reading

Reaper Madness

What is virtualization?

No advance in information technology in the past six decades has offered a greater range of quantifiable benefits than has virtualization. Many IT professionals think of virtualization in terms of virtual machines (VM) and their associated hypervisors and operating-system implementations, but that only skims the surface. An increasingly broad set of virtualization technologies, capabilities, strategies and possibilities are redefining major elements of IT in organizations everywhere.Virtualization definition Examining the definition of virtualization in a broader context, we define virtualization as the art and science of making the function of an object or resource simulated or emulated in software identical to that of the corresponding physically realized object. In other words, we use an abstraction to make software look and behave like hardware, with corresponding benefits in flexibility, cost, scalability, reliability, and often overall capability and performance, and in a broad range of applications. Virtualization, then, makes “real” that which is not, applying the flexibility and convenience of software-based capabilities and services as a transparent substitute for the same realized in hardware.To read this article in full or to leave a comment, please click here
