Create groups and assign addresses, services and parameters to pass or block connections It is first, a GUI, allowing you to configure the ipfw firewall, and as well offers added enhancements for the af firewall. For instance, a packet-filtering firewall could accept file-sharing connections from IP addresses of your work network but not from other addresses on the Internet.” What Is IceFloor? Packet-filtering firewalls like ipfw classify network traffic two ways: by type, using port numbers, and by origin and destination, using IP addresses. “In security parlance, ipfw is a packet-filtering firewall: it checks each packet coming or going through the Mac’s network interfaces against a set of rules, and allows it to pass or blocks it. The Unix-based IPFW firewall (Packet-filtering firewall).

If the program isn’t on the list – as in the case of new or upgraded software – OS X asks you whether to allow the program to accept incoming traffic.”Ī downside to socket filtered firewalls is that they can’t distinguish between “trusted” and “untrusted” addresses, and thus possibly creating more problems than the firewall itself solves. If the program is on that list, the firewall allows the connection. “When a program asks to accept network traffic, a socket filter checks a list of programs that have been authorized to do so. Here, network requests are based on the application making the request. Your Mac has two very advanced ways of doing this. In doing that, its real strength becomes clear: that is, determining “what” to let in, and “what” to let out.

If you think for one moment that your computers are safe on your home or small business network, you are sooner or later going being setup for a rude awakening. Hackers have gotten really good and their efforts are multiplied many times over by their use of bots. It isn’t really important where these guys came from, it is only important that they are floating around my network, NOW.Īs time has passed, technology has improved, for both people who are simply using their computers, and for those people who are trying to take advantage of the people who simply use their computers. The fact that these “guys” have gotten past my lame router firewall, tells me their presence is not one bent on extending goodwill to my network activities. Of course, most of the visible addresses are mostly “spoofed”, and any back-trace will probably run you through a number of servers, – good hackers simply cover their tracks. There is activity that appears to be from China, Russia, Europe, and so on. Today, I often watch who is traveling around my home network. Hackers and bots destroyed the innocent view that my home network was a safe place for me to play in. This of course, proved to be a text-book example of denial. I didn’t use software firewalls on my local computers.
