WPA2 Key Reinstallation Vulnerabilities (KRACK) Explained
Posted by Hemant Chaskar on Oct 16, 2017
WPA2 Vulnerability.png

Researchers from the University of Leuven (@vanhoefm and team) have discovered flaws in WPA2 implementation in clients and APs. These flaws create vulnerabilities for replay and decryption attacks on packets transferred over WiFi links. They have named them KRACKs (Key Reinstallation AttaCKs). Both 802.1x (EAP) and PSK (password) based networks are affected. These vulnerabilities have been cataloged under 10 CVEs. In the series of videos below, I explain these CVEs in detail with Vivek Ramachandran, Founder and CEO of Pentester Academy.

Is your Business Wireless Network Secure?
Posted by Jeff Olson on Oct 10, 2017

We’ve Got Your Back.

Security is top of mind for IT teams, business leaders, and the general public. News of attacks, ransomware, and data breaches has become commonplace; most recently Equifax and Yahoo. Have you stopped to ask yourself: Is my WLAN secure? Have I done all that I can to ensure is it secure?

Witnessing ethical train wreck after train wreck in Silicon Valley, it’s easy to conclude that the quest for success at all costs is a recent phenomenon and one limited to startups.

Auto Packet Capture, Where Have You Been All My Life?
Posted by Robert Ferruolo (Dr. RF) on Aug 8, 2017

You can tell how long someone has been troubleshooting networks by the length of their arms. Orangutans like me have been doing it a long, long time.  I started with a sewing machine sized Network General luggable that I carried around the world. Now I have to stand up very straight  to keep my knuckles from dragging on the ground.

Mojo’s Cognitive WiFi platform - Aware, saves network engineers from having to have shirts specially made because it includes Auto Packet Capture.

Using Mojo RESTful APIs and Alexa to Perform a Live Network Test
Posted by Murthy Jvr on Jul 28, 2017

The power of Mojo APIs can be harnessed to build a variety of useful applications. One such application is an Alexa skill that can provide a voice interface for Mojo Cognitive WiFi. In this example I show how to build an Alexa skill that runs a live client connectivity test for any of your network locations and then tells you the results. This example uses the Alexa skills kit API and the Mojo’s RESTful APIs. 

A Mojo Customer Story: Merseyrail's Seamless WiFi Experience for Passengers
Posted by Erika Hashemi on Jun 29, 2017

Merseyrail is one of the most punctual and reliable railway networks in the UK, running 800 trains and carrying over 100,000 passengers daily.
Merseyrail is currently 14 years into a 25-year concession managed by local transport authority, Merseytravel. Concession reviews are undertaken every five years, and it was between two review dates that Kevin Lindsay, Business Systems Support Analyst for Merseyrail became aware of the spike in passenger demand for WiFi access and recognized that something had to be done.

Accelerate the Digital Enterprise with a Cognitively-Enabled WLAN
Posted by Nolan Greene, Sr. Research Analyst, IDC on Jun 12, 2017

What were once revolutionary words when talking about enterprise WLAN – monitoring, visibility, single-pane-of-glass management – now sound conventional to the ears of network managers. Today, for many, the features those words describe have evolved into what is now known as the “cloud console.”

As WiFi networks have moved from merely supporting the business to serving as its backbone, WLAN management must evolve as well. Yesterday's security, scalability, and remediation are inadequate for the digitally transformed enterprise in which WiFi is the conduit to customers, suppliers, and mission-critical business applications.

Toward a Vision of a Smart Classroom
Posted by Dr. Bhaskaran Raman on May 30, 2017

Have you imagined classrooms of the future, how they would look?  Today, despite the smart-device revolution and near-ubiquitous networks, technology is viewed as a distraction in a classroom, and even more so in an exam-room.  Having taught several classes of size 100+ at IIT Bombay, I believe that technology can be a positive enabler in a smart classroom.  Future classrooms should have enhanced interactivity, and enriched communication through the correct use of technology.  Students should be able to collaborate with one another, and teachers should be able to interact better with students, get feedback on their understanding, and also conduct exams easily.  The path to this vision lies in the effective use of the smart-phones already lying in the students’ pockets, to build a smart classroom.

We have conceptualized several applications in this direction.  The applications below are in different stages of development: some in early prototypes, some well tested and used.
