    • A. Web Filtering Administration - The Computing Services Department shall administer Internet use for all computers and devices connected to the WNC network, excluding wireless. For security/reporting purposes all traffic accessing the internet through the system/appliance will record the source IP Address, the date, the time, the protocol, and the destination site or server. Where possible, the system should record the User ID of the person or account initiating the traffic. Internet use records must be preserved for 180 days.
    • B. Access to Web Filtering Reports - Computing Services may access all web filtering reports and data and such reports and data may be provided to SCS or NSHE as necessary to respond to a security incident. Such web filtering reports and data may also be made available to the WNC General Counsel in connection with any investigation and/or pending or threatened litigation.
    • C. Internet Use Filtering System - The Web Filtering system shall block access to Internet websites and protocols that present a security risk to WNC employee, student, and financial data because they have been identified as a source of viruses, hacking, peer to peer file sharing, SPAM, Phishing and Fraud, and/or Spyware. A blocked website will be made accessible once it has been determined the site no longer presents a security risk to WNC network, equipment, communications, and/or student, employee, and financial data.
    • D. Internet Use Filtering Rule Changes - The Computing Services Department shall periodically review and recommend changes to web and protocol filtering rules.
