A network analyzer, otherwise known as a packet analyzer, protocol analyzer, or network sniffer, is an incredibly prominent tool in the business world. These hardware or software applications intercept, inspect, and collect data traffic for the analysis of network statistics and problems, detection of intrusion attempts, and more.
Network analyzers intercept and record the traffic passing over your network. As its information flows through, the analyzer captures each packet of data. Some businesses or IT teams also wish to decode the raw data of each packet, which a packet analyzer is capable of doing.
How Businesses Utilize Network Analyzers
Businesses leverage these applications in many different ways. Network analysis gives you the ability to:
Keep in mind that while a network analyzer is capable of providing you with all of these capabilities, it is only as strong as its weakest link. This means that if a network design is flawed, there is no guarantee that your sniffer is giving you complete data.
For instance, an oversubscribed SPAN port may not provide 100 percent of your network’s traffic data, and if oversubscribed, it might not be available to allow an analyzer to do its job. A network TAP, on the other hand, provides foolproof access to your network and gives you the ability to monitor multiple network segments simultaneously.
Proper connection between your network and sniffer – or any network tools – is key to your ability to successfully monitor, capture, detect, debug, verify, and stay informed on your network. Without it, you can’t be certain that there isn’t anything falling through the cracks.
A network analyzer is a powerful, incredibly useful tool. But successful network analysis is an impossible task without complete access to a system’s network traffic. Full access is essential. With proper connectivity and complete access, a sniffer gives you important information and the power to manage your network.
