OpenSwitch in an OVA

First, disclaimer: I’m an HPE employee. Hewlett Packard Enterprise is a major contributor to the OpenSwitch project. Just thought you should know in case you think that affects my opinion here.

Network Engineers Don’t Like Learning New Things

Got your attention, didn’t I?  After the first couple of posts on OpenSwitch and a lot of discussions about this cool new project at some recent events, there was one piece of feedback that came back fairly consistently from the traditional engineers. OpenSwitch is hard to get running because there’s so many new things to learn.

When released in November of last year, the initial demonstration environment was actually pretty simple and streamlined to get up and running, as long as you’re a developer.  

The process involved the standard set of dev tools:

• Virtual Box
• Vagrant
• DockerToolbox
• Docker

 For anyone involved in a development environment, these tools are like an old hoody on a cold winter day. Welcome and familiar. 

But for the majority of network engineers who are far more comfortable with a console cable and Continue reading

Hottest Enterprise Networking & IT Startups of 2016

The billions of dollars invested in cloud, wireless, big data, security and other networking startups in 2015 means that enterprise IT shops will have plenty of new products and services from which to choose.On the heels of that year of the megadeal ($100M or more) and Unicorn (private companies valued at $1B or more), it will be interesting to see how funding for network and IT startups shakes out in 2016. We'll keep track of 2016 funding announcements of possible interest to enterprise IT pros here, so bookmark this page and check back for updates.

Preventing Malicious Request Loops

The web is an collaborative ecosystem. Web standards exist to ensure that participants of the network behave in a predictable way. If network participants deviate from the established standards then there can be unintended consequences. This blog post is about one of these unintended consequences.

A group of researchers recently published a paper "Forwarding Loop Attacks in the Content Delivery Networks" describing what can happen when web services interact in a non-compliant way. They describe an attack where a malicious user can force multiple service providers to send each other an unending stream of requests in a loop. This request loop can result in resource exhaustion and denial of service at the service provider. This paper also demonstrated that the attack is practical, and can be performed using a large list of service providers.

CloudFlare's service has been modified to be standards-compliant with respect to HTTP proxying. However, fixing the vulnerability that enables this attack requires all proxy services to conform to the same standards. If even one service provider is non-compliant, the attack can still be carried out against compliant services. In this post, we will describe the attack and explain how a proxy services can go from being Continue reading

Google creates fix for zero-day kernel flaw, says effect on Android is greatly exaggerated

After being caught off guard by the disclosure of a serious flaw in the Linux kernel this week, Google has quickly developed a patch for Android and shared it with device manufacturers.It might take weeks for device makers to start releasing firmware updates that include the fix, but that's not a huge problem since, according to Google's assessment, the flaw doesn't affect many Android devices to begin with.The privilege escalation vulnerability allows attackers to gain full control over Linux-based systems if they have access to a limited account or trick users into running a malicious application. It was found by researchers from Israeli threat defense start-up Perception Point.To read this article in full or to leave a comment, please click here

Fight for privacy of students, cellphone users moves to US states

The fight for privacy is moving to U.S. states with 16 states and the District of Columbia introducing legislation on Wednesday that address issues such as requiring permission before student data is shared for non-educational purposes and the requirement of warrants before using cell site simulators to track phone users.“A bipartisan consensus on privacy rights is emerging, and now the states are taking collective action where Congress has been largely asleep at the switch,” said Anthony D.

Ukrainian power companies are getting hit with more cyberattacks

A number of Ukrainian power companies are seeing fresh cyberattacks following ones in December that briefly knocked out power for tens of thousands of customers. Security vendor Eset said on Wednesday that the attacks use a different kind of malware, prompting questions about whether the same group or groups are involved. "The malware is based on a freely available open-source backdoor – something no one would expect from an alleged state-sponsored malware operator," wrote Robert Lipovsky, a senior malware researcher with Eset. The new finding deepens the mystery over who is targeting the Ukrainian companies.To read this article in full or to leave a comment, please click here

FireEye to grow intelligence capabilities with iSight Partners deal

FireEye has acquired Texas-based iSight Partners for $200 million, a deal that executives say will give FireEye stronger intelligence on cybercriminal and hacking groups before they strike.The transaction, announced Wednesday, closed on Jan. 14.FireEye started with an end-point protection product aimed at filtering out malware before it entered a company's network.
