Given the appropriate security policies, disclaimers, etc. by the employer, admins typically need tools to record and report on how the internet connection is being used by its employees.
In the past, I've relied on my firewall appliance to log the most viewed domain names. Very rudimentary stuff. It was difficult to track down who visited siteAbc123.com in a domain of 50+ computers. The egregious traffic was really what we were after.
If the requirements are to provide a report, on a per user basis:
- bandwidth used
- sites/pages visited + hitcount
- protocols used (i.e. streaming radio)
Can you suggest any free or low cost tools that would help gather and create reports on this information for a small-medium business in a Windows environment?
