  • Suspension of Access to the Campus Network

    The ITSC would suspend your VPN/Web access to the Campus Network and disable your current network connections when a huge amount of abnormal network traffic was generated from the computer that you were using (could be your personal one or a campus public one).

    This abnormal network traffic kept our network equipment busy in handling its flow and in turn resulted in a slow response on the Campus Network. To protect public interest, we would take prompt action to suspend your account.

    1. Causes of Abnormal Network Traffic

    The major reason that a computer produces abnormal traffic is that it is infected by a virus/worm or you have mis-configured a peer-to-peer software.

    1. Measures to Avoid Abnormal Network Traffic from Your Device

    1. Clean up the virus/worm
      Use an anti-virus scanner (e.g. Kaspersky) to check and remove a computer virus/worm.
    2. Check your computer regularly
      To avoid any inconvenience caused by account suspension, please check out the recommendations here to protect computers from viruses or other attacks.
    3. Mind the risks of Peer-to-Peer File Sharing
      Pay attention to the risks you may be exposed to when using peer-to-peer software by visiting Risks in Peer-to-peer File Sharing.
