So where are we supposed to learn this. Is there some kind of list sowewhere?

So far I have found only a little here and there.

 

The only thing for rules is next to nothing and I have all kinds of ports open that I shure did not set, since this is the first time I have really checked the firewall settings.

 

Another thing which windows firewall are we supposed to us the one in windows or the Desktop Win firewall app.

 

Thank you.

Here are a few links which may be helpful.

Allow a program to communicate through Windows Firewall

What are the risks of allowing programs through a firewall?

When you add a program to the list of allowed programs in a firewall, or when you open a firewall port, you allow a particular program to send information to or from your computer through the firewall. Allowing a program to communicate through a firewall (sometimes called unblocking) is like punching a hole in the firewall.

Each time you open a port or allow a program to communicate through a firewall, your computer becomes a bit less secure. The more allowed programs or open ports your firewall has, the more opportunities there are for hackers or malicious software to use one of those openings to spread a worm, access your files, or use your computer to spread malicious software to others.

It's generally safer to add a program to the list of allowed programs than to open a port. If you open a port, it stays open until you close it, whether or not a program is using it. If you add a program to the list of allowed programs, the "hole" is open only when needed for a particular communication.

To help decrease your security risk:

Only allow a program or open a port when you really need to, and remove programs from the list of allowed programs or close ports that you no longer need.

Never allow a program that you don't recognize to communicate through the firewall.

Thank you so basically everything in the allowed folder you are actually supposed to allow?

A lot of what I saw is not something that I would want going in or out.

I do not want to share my computer with anyone. Nor should I have to.

 

What possible reason would I need to have installed by default all of the C++ code read /write software. I am no developer or hacker or coder in anyway. It's like Microsoft wants to make it readily available just in case, sort of like here hacker/malware writer you can write and store your code over here no need to bring any tools we have provided them for you. When the cops go knocking down doors it won't be yours. Your PC will be clean as a whistle. One of the primeary reasons for Bots and bot nets.

 

I know 2 of my computers became bot store houses for stolen music, 25,000 songs and not a one of them mine.

When I started deleting their stuff they crashed the computers.

First I want to apologize for my rant. Very good information but still no actual list of what should or should not be allowed thru.

 

The allowed list given is almost a 100 programs /apps/services etc.  Surely not all of that is absoloutly necessary.  However it may be a way to finally Kill Cortana and it's snooping.  Maybe, during my research on this Cortana is tied into the start menu search engine.

If I killed its inbound/outbound connections in the firewall would the search function still work for the PC.

 

I mean to get to a lot of the Computers functions you have to use that search field. Or would it just kill it's ability to search/exchange information on the web only?

 

Thank you again for the links I been busy reading them all LOL a lot of information to absorb.

Not a problem.

I have used Windows Firewall for years and have always left everything with default settings. While I have looked at the list of Allowed Programs on my machine, I have never had the need to change anything. Never had a problem or issue to be concerned about.

I made my post because of the other post about something on his system was not running with the recommended settings.  So what are the recommended settings and according to who?
