Today we ran a PCI DSS compliance check and failed due to UDP port 161 being open. My first thought was "Ok, I'll just close it".
We have Charter Business and they now lock admin access to the modem/router and do not let customers access the device. So my next step was to call Charter and have them close the port on my device and they said they do not do that, only port forwarding. I could always have the Charter modem bridged and add a router behind the modem and block the port there, but this is a small business, one PC and CC terminal are the only devices and I do not want to add the cost of a new device. Also the employees are not tech savy and having another device for them to deal with would be cumbersome.
Do I have options or do I have to suck it up and add a separate router?
