I am staying in the CERN hostel and use my personal laptop. Why should CERN care what websites I visit?

Even if you use your own computer, on your own time, you are using CERN’s network resources and, in particular, a CERN-owned IP address.  This means that any network activity, which includes visiting websites and blogs, may be tracked back to that CERN IP address.  Your activity could, therefore, have a negative impact on CERN’s reputation, for example if you exchange copyrighted files via P2P networks.  Please review the CERN Computing Rules, as set out in Operational Circular No. 5, and ensure your use of your computer and CERN computing facilities is in compliance.
