With Half Term on the horizon, it might be a good idea to review the firewall access that you have in place. Are there legacy firewall rules that can be removed? Of course if firewall rules are no longer needed, the access should be disabled. I would encourage you to pay particular attention to inbound access. Have you previously deployed access to an internally hosted server that has since been decommissioned? Or have you provided access for a company to connect into the school network and you no longer work with them? It is the school’s responsibility to let us know if access is no longer required, otherwise it will remain in place.
To find out what is in place at your school, please get in touch with our Broadband Service Desk. We would recommend you viewing this information in SafetyNet and we will be happy to talk you through the information that you are looking at.
