Every time your phone loads a page, your laptop sends an email, or an app checks for new messages, data is moving across a network. That movement is network traffic. It’s basically the digital stuff travelling between devices.<\/p>\n
Some of it is tiny. A quick message barely registers. Streaming a video is different, because the network keeps pushing data for as long as you’re watching. Most of it happens quietly in the background, so you stop noticing it.<\/p>\n
Think of a network like a road. Devices are the places sending and receiving, and packets are the little chunks of data travelling between them. Network traffic is just that activity.<\/p>\n
A business network might have hundreds of devices talking at once. Someone opens a file in the cloud, another person joins a video call, a printer gets a document. Every one of those creates traffic. Network teams keep an eye on it because unusual activity often shows up there first, like a sudden spike from one computer.<\/p>\n
Most traffic is completely ordinary. Your browser asks for a page and the server sends data back. Your phone checks an app for updates. Nothing exciting.<\/p>\n
Web browsing feels almost instant when the network has room to spare. Video calls create a steady stream, since your voice and camera keep moving between devices. And a sudden burst isn’t automatically bad. A big file transfer can create loads of traffic without anything suspicious going on.<\/p>\n
It’s data moving across a network for a harmful or unauthorised purpose. The traffic itself isn’t the problem. What someone is trying to do with it is.<\/p>\n
An attacker might send requests to a vulnerable server. Malware on an infected computer might quietly talk to another system. Someone might also flood a service with so much traffic that real users can’t get in. Security tools look for patterns that don’t fit normal behaviour.<\/p>\n
No single pattern proves an attack is happening, but some things are worth a look, especially if they show up suddenly or keep repeating. Repeated connection attempts to strange destinations stand out, particularly when the device has no reason to contact them.<\/p>\n
So does a computer sending far more data than usual while its owner is just doing regular office work. And an unexpected device suddenly getting very busy at 3 a.m. is hard to ignore. Odd hours aren’t automatically bad, but that one deserves a second look.<\/p>\n
Normal traffic supports something a person or system is trying to do. Malicious traffic serves an unwanted purpose, like getting access, stealing information, spreading malware, or knocking a service offline.<\/p>","protected":false},"excerpt":{"rendered":"
