We often get emails from readers stating that they feel their system is compromised, even though they “do nothing”. Most of the time, our response is “that’s normal”. Indeed, most modern operating systems, not just Windows, will trigger lots of network traffic without user activity. But I found little documentation about what exactly to expect from a “normal” Windows 10 system. So I ran a quick experiment:
Microsoft offers a number of free virtual machines. I picked the “Microsoft Edge Windows 10 (x64) Stable 1809” system.

About | SANS Internet Storm Center |
The ISC was created in 2001 following the successful detection, analysis, and widespread warning of the Li0n worm. Today, the ISC provides a free analysis and warning service to thousands of Internet users and organizations, and is actively working with Internet Service Providers to fight back against the most malicious attackers.
The ISC relies on an all-volunteer effort to detect problems, analyze the threat, and disseminate both technical as well as procedural information to the general public. Thousands of sensors that work with most firewalls, intrusion detection systems, home broadband devices, and nearly all operating systems are constantly collecting information about unwanted traffic arriving from the Internet. These devices feed the DShield database where human volunteers as well as machines pour through the data looking for abnormal trends and behavior. The resulting analysis is posted to the ISC's main web page where it can be automatically retrieved by simple scripts or can be viewed in near real time by any Internet user.
