This information is invaluable in determining what is going on if you don't recognize the software trying to make a connection, or if a popup appears when you're doing something completely different (i.e., this is from a program you did not tell to activate).

There is a Show Details link in the popup that you can click to see exactly what is happening. If you start seeing connection attempts from a program you do not recognize, however, then it's time to pay attention to what Little Snitch is telling you. For instance, if you are uncomfortable with a program "phoning home," you can deny all connections to the program's Web site, but allow connections to every other host.Īs new programs are installed, Little Snitch checks with you first as to whether the connection should be allowed or not. You can also get specific: allow any connection the program makes allow it to the specific port it is attempting to connect to allow blanket connections to the host it is attempting to connect to or only allow to the specific host and port. When they do, you are given a choice of allowing the outbound connection: you can allow the program to establish one connection until the program terminates allow it forever or deny it. Almost everything on the system will be unknown, so as you use your applications, Little Snitch popups will occur. Little Snitch comes with a very restrictive default set of rules. Little Snitch is not free software but the $30 USD it costs is a small price to pay for the security and confidence Little Snitch provides. Luckily, OS X users can use a program called Little Snitch to inform them of outgoing connections. It won't be able to distinguish whether the connection is from Safari, an email client, or a piece of malware. If a connection is established from the inside heading out, most firewalls will assume it is a legitimate connection. The firewall won't protect you from a rogue process connecting to a remote machine when the connection is originating from your own system. You can download some malware yourself, which gets it in past the firewall, and accidentally run it. So unsolicited connections coming at the computer are covered, but what about the other way around? Outbound connections can be just as problematic, particularly when viruses, trojans, and other malware abound. Running a computer or network without a good firewall these days is more than just foolish - it is plain old negligent. Firewalls are by no means a silver bullet, but they are one of many tools to protect networks and individual systems. Firewalls are a first line of defense against malicious people that will attempt to hijack a computer for their own nefarious needs.
