On Monday Mathy Vanhoef and Frank Piessens, from the University of Leuven, published a paper disclosing a series of vulnerabilities that affect the Wi-Fi Protected Access (WPA) and the Wi-Fi Protected Access II (WPA2) protocols. These vulnerabilities described a set of scenarios where a malicious user can perform a man-in-the-middle replay attack on wireless users connected to the network using the WPA and WPA2 wireless protocols. By spoofing the address of an access point and replaying the authentication 4-way handshake the malicious user can force the supplicant end device to reinstall an old key-pair, which is why it is being referred to as “KRACK” (Key Reinstallation AttaCK).
I was recently called in to assist a customer with identifying the cause of slow performance for an application within their environment. I don’t know about you but I love a good networking who done it, so I could not resist accepting the case. The following blog post documents my experience and findings while working this investigation that will from here on out be known as the “The Case of the Slow TCP Retransmissions”.
In this Fireside Chat CEO, Sean Barr, sits down with Consulting Services SME, Dominic Zeni, to discuss Cisco’s introduction of software defined networking for the access layer of campus and branch office networks: SD-Access. Sit back, relax, and enjoy this Fireside Chat.
Earlier this year Cisco released their new Digital Network Architecture (DNA), which they are calling “intent-based networking”. Cisco DNA is an open, programmable architecture that turns business intent into business results, and is the foundation for The Network. Intuitive. Cisco also released their Software-Defined Access (SD-Access) solution, which is the “industry’s first intent-based networking solution for the Enterprise built on the principles of Cisco’s DNA”. SD-Access provides
Rejuvenated, inspired, and re-energized. Those three words best describe how I felt leaving INBOUND 2017. And, what perfect timing for a new gust of wind in my marketing sails! Every year in June and July we see a burst of new energy in our industry as Cisco releases new technologies at Cisco Live, and as they close their fiscal year. As that momentum begins to slow a fresh burst of energy and new marketing initiatives centered around customer delight is an ideal way to round out 2017.
The final day of INBOUND 2017 kicked off with a keynote featuring Pixar Animation Studios co-founder, Dr. Ed Catmull. Catmull shared his success and failures at Pixar, as well as his insights about creativity today. He discussed the importance of change, responding to challenges, listening, empathizing, and making mistakes. The goal when founding Pixar was to build a sustainable culture. He enlightened the audience on the struggles of each Pixar film, and shared that Pixar “does not make movies for kids. They make them for adults – kids live in an adult world and are trying to figure it out.” He encouraged everyone to keep trying new big projects, because even for Pixar every film struggles before being good. Ego must be removed for creativity and “magic” to happen, and “it is easier to correct errors than to try and prevent them altogether”.
Day 2 of INBOUND 2017 has come to an end, and it has been one for the books. The day began at 6:45am in line to see Michelle Obama’s keynote at 9am. All I can say about that is her keynote was worth the wait! I could write an entire blog about her insights, demeanor, and control of the room, but for the sake of this post I will keep it to my key takeaways.
INBOUND is HubSpot’s annual marketing conference, and I am in Boston this week for INBOUND take two! The conference kicked off last night with an inspirational keynote featuring best-selling author Brenē Brown. She spoke about her new book, Braving the Wilderness: The Quest for True Belonging and the Courage to Stand Alone. She also talked about how true belonging doesn’t require us to change who we are – it requires us to be who we are.
Cisco has rolled out a new way to allow customers and partners to manage software licenses. This new feature is called Smart Accounts, which lets you view and control access to all your Cisco software licenses and entitlements across your entire organization. Once you set up your Smart Account you will be able to create up to 200 sub accounts called Virtual Accounts, which allows you to organize and manage your licenses by departments, locations or types of licenses, throughout your organization. Smart Accounts allows you to have access to your licenses and software at all times, without having to rely on your provider to distribute. No more having to wait for a provider to deliver licenses and delaying projects, with your Smart Account, all your needed licenses and information are a click away.
You have been working as a network administrator for your company for a few years now. In that time you have been asked to complete a handful of network projects; a new office turn up here, replace some switches or a router there. The whole time you work from old templates or, in the case of replacement gear, just copy and paste the old config. Have you ever really stepped back and looked at the network as a whole, or more importantly do you have time?
