I have a server that I want to restrict access to by allowing only one IP address to be able to connect to it through desktop and make http request through port 80.
Now in my firewall I only have World Wide Web Services (HTTPS Traffic-In), Remote Desktop - User Mode (TCP-In) and Remote Desktop - User Mode (UDP-In) rules enabled with scope of the IP that I want enabled.
Except there are a bunch of other Core Networking rules enabled in the firewall. Do these open rules pose a threat and should I apply the same IP restrictions to these rules too?
Can a hacker exploit these rules?
I'm assuming disabling these would interfere with updates, time management etc. but if they can be exploited I'm willing to compromise these.
