Firewall software for Mac

Do You Need to Enable It?  October 3, 2016 – 04:12 pm

Mac OS X ships with a built-in firewall, but it’s not enabled by default. The Windows firewall has been enabled by default ever since worms like Blaster infected all those vulnerable Windows XP systems, so what gives?

Macs to include a firewall, which you can enable from Security & Privacy in System Settings. Like firewalls on other operating systems, it allows you to block certain incoming connections.

What a Firewall Actually Does

Firewalls like this one do one thing: They block incoming connections. Some firewalls also allow you to block outgoing connections, but the built-in firewalls on Mac and Windows don’t work in this way. If you want a firewall that will allow you to choose which programs get to connect to the Internet or not, look elsewhere.

An incoming connection is only a problem if there are applications listening for these incoming connections. That’s why a firewall was so necessary on Windows all those years ago — because Windows XP had so many services listening for network connections, and those services were being exploited by worms.
