We are very busy this week getting ready for CiscoLive! 2013 in Orlando next week.  Since we have a first rate team getting us ready for the show, I had a block of time to put together three primary thoughts I’ve collected regarding mistakes some people make in their cyber threat detection routines.

I have two goals with this post, the first is to announce that you can sign up for the joint webcast we are hosting with Cisco Systems regarding the release of the Catalyst 2960-X with NetFlow-Lite Support.
•    10AM – Sign Up
•    4PM – Sign Up

The second goal is to explain how to configure the 2960-X NetFlow-Lite Support.

The Cisco Catalyst 2960-X NetFlow-Lite configuration is pretty straight forward however it is very different from the IPFIX PSAMP “NetFlow-Lite” we configured on the Cisco 4948E NetFlow-Lite.  The 2960x uses flow sampling without any form of packet capture.  There are two types of possible NetFlow Lite sampling configurations on the 2960x:

• Deterministic Sampling
• Random Sampling

What is a security threat? A network security threat is any unwanted traffic trying to get onto your network or cause harm to it. Today I want to talk about a DNS reflection attack which is when attackers send a large number of queries from a spoofed source address to your DNS.  The address which is spoofed is typically that of the victim.  When the requests are received by the name server, all ensuing responses to these queries are directed back towards the spoofed IP of the victim.  Recently, one of our customers detected a DNS reflection attack with our network threat detection solution and shared the following story.

Username NetFlow Reporting is a hot topic since the Cisco Visual Networking Index (VNI) report in late May. By 2016, Cisco’s forecast predicts that there will be “nearly three networked devices per capita”  Naturally, people are asking “Who is authenticating all of these devices onto the network?” Read more »

Using Cisco Application Visibility and Control (AVC), network administrators can manage network application performance by setting up a wireless policy to prioritize, control, and bring visibility to the BYOD applications traversing their network.

There are many challenges IT managers face on a daily basis. As the number of user devices and the business, personal and collaborative applications continue to grow, these challenges only make the job of an IT manager harder.

Today’s networks support a mixed use of guests, employees and vendors. Without classifying and prioritizing applications on the network, employees risk losing productivity and response time to critical applications that they use.

Imagine what goes through the mind of an IT administrator who is responsible for getting a handle on device and application growth and usage on their network:

• Is a guest downloading movies using Bit-Torrent – in other words, stealing valuable airtime away from my mission-critical applications?
• What are my top users and applications?
• Can I prioritize business-class applications and de-prioritize the applications such as Netflix?
• Do I need more Access Points?

So how is Cisco AVC going to help on your wireless network access points?
