First of all, Net Flow  is spelled NetFlow, and today, we’re going to talk about an IT Monitoring Service that provides Network Traffic Monitoring.  Specifically, we want to monitor BYOD Traffic.  The modern workplace is often being assaulted by these devices.  Why? Androids and iPhones are constantly searching for a Network to connect to.  Once attached, some employees are so ‘connected’ with friends that these smart phones start flooding the network and pestering the user to participate in Facebook, Farmville or even Scrabble.  How can you find out when, what and where they are doing?

What is Flow Analytics™ ?

Flow Analytics™ is a built-in module that a NetFlow analyzing tool uses to perform network behavior analysis. Flow Analytics™ can trigger alarms for such behaviors as worms, network scanning, and known compromised internet hosts. It can alarm you if any DoS attacks are happening. Once that happens it can identify repeat offenders and create a Unique Identifier (UI) to manage traffic counts. Flow Analytics™ can also identify your top applications, conversations, protocols, etc across dozens of routers and switches.

Flow Analytics™ allows you to store data for more than 24 hours. You can choose to save an infinite amount of Net Flow data history at every interval. So now you can go back and identify a problem that occurred 2 weeks ago on your network. Flow Analytics™ also allows for automated DNS resolution to help you quickly identify culprits on your network.

What makes Flow Analytics™ incredibly amazing is the ability to look at the NetFlow from multiple routers and switches simultaneously every 5 minutes. Potentially, you can configure hundreds of devices for each algorithm in Flow Analytics™. In this blog I will show you how to set up Flow Analytics™ and how to start configuring it. Read more »
