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.

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. Vincent Danen describes the privacy-protecting software called Little Snitch for Mac OS X, which helps you keep track of outgoing connections and includes a network monitor.Įveryone knows the value of a good firewall.
