Cisco’s recent acquisition shows exciting times ahead for the lead players in the cloud Wi-Fi space

Cloud Wi-Fi space

Barely two weeks after I posted my last blog discussing benefits of the true cloud Wi-Fi over the controller over WAN architecture using Cisco FlexConnect as example for the latter; news of Cisco acquiring Meraki broke out. I got a kick out of it since it showed that my inferences on Cisco FlexConnect and other… Read More

Is your cloud Wi-Fi genuine, or is it controller over WAN imitation?

_MG_0292

With rising popularity of the cloud Wi-Fi in the distributed Wi-Fi deployments, there is also an attempt to pass off the legacy controller technology as the cloud Wi-Fi by deploying conventional controllers over the WAN. Realizing that it is infeasible to deploy many smaller controllers in the distributed Wi-Fi deployments such as retail, remote offices,… Read More

A tale of the two WLAN controllers, do we need to be chasing our tail for the WLAN security?

Right when the Wi-Fi access and security management are moving towards the controller-less architecture, another interesting architecture seems to have evolved at the other extreme. This architecture seems to be advocating not one, but two WLAN controllers in tandem – and that too from two different vendors. And, some optional (additional?) security management servers on top of… Read More

Skyjacking attack – then Cisco, now Aruba?

Recall “Skyjacking” vulnerability discovered with Cisco LAPs couple of years ago? It allowed hacker to transfer control of enterprise Cisco LAPs from enterprise WLC to hacker controlled WLC in the Internet with over-the-air attack. Once control is transferred, the hacker could change configuration on those LAPs in any way by adding, deleting and modifying SSIDs. The hacker could… Read More

Cisco AP Skyjacking

This latest vulnerability on Cisco WLAN (AP Skyjacking) points out the importance for customers to deploy overlay WIPS to have a zero day response capabilities in place. Making changes to your WLAN controller, APs, and firewalls takes time and new vulnerabilities like this will continue to surface.  A dangerous exploit that can be carried out using this vulnerability… Read More

Is skyjacking a mere DoS threat against Cisco WLAN?

Skyjacking vulnerability which allows Cisco LAP to be diverted to connect to rogue controller by manipulating OTAP could be more dangerous than what has been clarified by Cisco in its advisory. The advisory says that “An exploit could prevent the device from functioning properly, resulting in a DoS condition. There is no risk of data loss… Read More
