Over the course of the last few weeks we have held a number of webinars with customers about NPM version 11 and the new deep packet inspection and analysis capabilities. Throughout those webinars, a number of common questions have come up. Below you will find a list of FAQs that we hope will address most of those…
In my last blog, I introduced some of the basics of network security and why enforcing traffic on the standard source port isn't enough to determine what’s in a payload. I've talked mostly about port 80 and HTTP, but the ports associated with DNS (UDP 53) are also often abused. In the context of firewalls, Deep Packet…
Deep packet inspection (DPI) is a technology used to capture network packets as they pass through routers and other network devices, and perform packet filtering to examine the data and find deeper information about the data carried by the packets. Unlike stateful packet inspection (SPI aka shallow packet inspection) which…
Stop the finger pointing with NEW Deep Packet Inspection & Analysis We know you've been there. The network is always the first to be blamed when application performance is poor. Then the finger pointing begins. It's the network! No, it's the application!..Now you can tell if application performance problems are the result…
In my last post, I talked about some of limitations of DPI and the kind of tools used to combat it. However, DPI is useful in a couple of other scenarios and in this final post, I’ll cover them also. Traffic Optimisation As traffic flows across a network, it needs to be managed as it crosses points of contention. The most…
In this series of blogs I’m going to explore some of the use-cases for deep packet inspection on the network and types of devices that use it. I’ll also cover some of the common caveats for each specific definition and possible resolutions. There are (at least in my estimation) three common(ish) use-cases for Deep Packet…
In my last post I talked (briefly) about Protocol Anomaly Detection (PAD) and Signatures. My original intention was to talk about other topics, but given that the security aspect has been so popular, I'm going talk more about the security aspects and (quickly) circle back to optimisation and performance management later.…
In order to make the process of upgrading to NPM v11 as easy and seamless as possible, we have pulled together a number of resources to assist you. The Benefits of Upgrading to NPM 11 * Benefits of Upgrading to NPM 11: In this 2-minute video, Rob Hock, SolarWinds group product manager, guides you through the newest…
