Packet analysis can gather network statistics, monitor protocol and bandwidth use, analyze network problems, perform content monitoring, and run in real time—or you can capture traffic and save for later analysis.
- On today's complex networks,…administrators face multiple cyber threats.…We respond in one of three ways.…Proactive, and that is security…where we actively try to prevent threats.…Reactive, and that is forensics…where we go in and assess the damage.…And active is where we periodically check the network.…Sniffing the network, or packet analysis…is a valuable skill for the network administrator…and should be part of every…network administrator's skill set.…
We can scan an individual system,…or we can look at the traffic…that's flowing across the network.…Network administrators should spend a few minutes every day…and take a quick look at the traffic.…This will give us a great deal of information…on the status of the network.…Sniffing traffic can gather network statistics,…verify endpoint security status,…and monitor protocol use.…
You can check, are there any protocols that…should not be on your network.…Such as unauthorized instant messaging,…gaming or even bitcoin mining.…Analyze network problems…and detect network intrusion attempts.…
