When your Mac computer is connected to the Internet, countless connections will be quietly built in the background. Once some application connects to the Internet, it can send any information that it wants to send to any place in the world. In order to monitor these connections, better maintain our privacy security, and especially withstand the tracking software, Trojans, or other types of malware, we usually have to use the boring and difficult to use firewall software. Even worse, the inbuilt firewall program of Mac OS is only able to control incoming connections, has no monitoring and controlling capabilities for outgoing connections.

Little Snitch is an excellent, easy-to-use and trustworthy personal firewall software for Mac, developed by Objective Development Software from Austria, written in Objective-C. It can be used to monitor and prevent any network connection (both inbound and outbound) generated by the specified software. For example, when you launch some software, Little Snitch will remind users to allow it to connect to Internet or not. If you have a lot of confidential data stored on your Mac, it’s very necessary to install a user friendly firewall like Little Snitch. It reminds you of all inbound/outbound network connection requests in real time, so as to protect the safety of user’s computer effectively, and prevent applications from secretly accessing the network and sending data to the outside.

Once you connect to the Internet, the application may optionally send any thing they want. In most cases, they will bring you a lot of benefits. But for some software, what they do to us is opposite, such like tracking software, Trojan, or other malicious software. The trouble is that you didn’t notice anything about what and how they are doing, because all of this is conducted secretly. This case, Little Snitch can make any network/Internet connections sleep with the lights on (from invisible to visually visible), and enables you to control everything!

// Tips //

• You can selectively let familiar software free access the Internet, and limit the activities of applications that don’t need Internet connection or you don’t know what they are and where they are from to local (i.e.: offline use). Thus, you will be able to turn passive defense into active defense even in the face of all sorts of known or unknown Trojans or viruses.
• Look at it another way, you can also use a firewall program to organize and control the license network verification mechanism of many software, in order to assist the software cracking process.
