Every minute or so my firewall keeps blocking the following message:
Rule "Default Block SSPD" blocked. Port 2869. Inbound TCP Connection. Process name is System. It keeps happening over and over again. Is someone trying to get into my computer.
Hi mmalone,
Simple Service Discovery Protocol is used by devices on a Local Area Network to announce themselves and to discover other devices. It is normal to see SSDP multicasts originating from devices on a LAN. By default, Norton will block this traffic if there is no file and printer sharing enabled on your computer. If you had sharing enabled, Norton would allow the traffic in order to facilitate your networked devices being able to find each other. You are not being attacked - Norton is simply monitoring your network traffic and logging the actions it is taking in accordance with the general firewall rules.
