This will block anything that doesn't have a rule created for it. You should block everything except DNS and web browsers, for doing this go to the Advanced settings -> firewall settings and enable "Do NOT show popup alerts" and change the dropdown to Block Requests. If you want to use Komodo Internet Security (KIS) or Comodo Free Firewall (CFF):Ĭomodo firewall Whitelists help you by including all the items below, and nothing else is allowed into the system: You can see the Thiny wall white-list in below image: List established and blocked connections.Recognition of safe software and impostors.Option to restrict an application to the LAN.Option to always allow communication within LAN.Support for temporary/timed firewall rules.Quick modes, like Normal protection, Allow outgoing, Block all, Allow all and Learning mode.Multiple and easy ways to whitelist programs.Most importantly, with the no-popup approach, the user will only notice that a program has been denied internet access when he can't use it anymore.Ĭonsequently, users will only unblock applications that they actually need and none more, which is optimal from a security standpoint. This approach avoids popups, but still keeps the firewall very easy to use. Of course, the traditional way of selecting an executable also works. Or, you can select an application from the list of running processes. Instead of showing popups, TinyWall makes it easy to whitelist or unblock applications by different means.įor example, you can just initiate whitelisting by a hotkey, then click on a window that you want to allow. In fact, it will not notify you of any blocked action at all. It does not display popups that "urge users to allow". TinyWall takes a different approach from traditional Firewalls. If you're using OpenVPN you will also need to add two more Outbound rules:Ĭore Networking - Dynamic Host Configuration Protocol (DHCP-Out)Īnother very useful, powerful and of course free here: Outbound - only "Core Networking - DNS (UDP-Out)" is enabled Inbound - there's not a single rule here! For example my settings are as follows (excluding my programs): So you can experiment, disabling rules and making your machine more secure. You can import/export rules by right clicking the same as in screenshot above and selecting Export Policy. Now you can add only the programs you want to the list. There, right-click as shown in screen shot to get the properties:Ĭhange Outbound Connections to Block for each profile Go to: Control Panel\System and Security\Windows Firewall The way to do this (though somewhat hidden away way) is to change the settings as follows in these 3 easy steps: You can do this using Windows built-in Firewall. You want to Block all Inbound and all Outbound connections by default. Outbound - Allow all unless in the list (Blacklist).Inbound - Block all unless in the list (Whitelist).You do not need any 3rd party firewall software.īy default windows firewall functions as follows: I'm not an expert, So please try to give a detailed answer as I don't know anything about ports and some other expressions that I came across when googleing this. I'd like there should be an option or button to makes it possible for me to edit, add or delete application in this list manually. With that definition in mind, everything is automatically blocked and cannot be used. Notice that whitelisting is different than blacklisting, in that whitelisting blocks everything and then allows a few things later. Only application in this list will be able to communicate. Then, I set up the " white list" - meaning the list of good destinations that I want to allow.Ī list of applications that I'd like to grant network access to them. " any/any" = any source, any destination). What I wish to achieve is a " whitelisting" - meaning that I set up 1 rule on a firewall that says "block everything" ( deny all any/any, where I see for blocking application but seems you need to add one by one and it is a tedious task. How can I set up a config like this in windows Firewall? I would like to allow only one web browser like firefox, chrome or opera. I would like to block everything, even including windows update and other software updates. Is it possible to auto block all applications incoming/outgoing internet connection except for example Firefox with default windows firewall?
