Customizing ASAM module in NetFlow Analyzer

The previous blog was on ASAM will have given you an idea about the class “Scan and Probes” available with NetFlow Analyzer. Now that we know how the events are triggered we need to narrow it down, that the specific events or unwanted events can be ignored.

Performance based IT Shop Part 2

Not all IT problems come under the domain of the network engineer. In my previous Blog , I talked about IT shops having a hodge-podge set of tools. There are various reasons, but the real inefficiency is when these tools perform the same functions. There becomes a time and need to look at the IT problems from different perspectives. A few examples below: Kenn Nied, Senior Network Engineer at WA State Board for Community and Technical Colleges, illustrates this encounter. While looking at OpManager from a networking point of view, the operator sees alerts that a few switches and a firewall are unresponsive. Is it faulty equipment or an attack? Then turning to a Security mindset, he looks at ManageEngine Device Expert to see real time and historical configuration changes. In one case, it was identified that there was a Firewall rule change made and realized it was a misconfiguration that caused the switch unresponsive. Diagnostic time was minimal. Albert E.
