Mac OS X has long included a basic firewall, but with the release of Mac OS X 10.5—also known as Leopard—this fundamental security technology is moving in a new and innovative direction. As with any major change in a popular operating system this transition comes with a learning curve, but thanks to the recent OS X 10.5.1 update from Apple, Leopard’s firewall is fairly straightforward and recommended for the average Mac user.

As a security professional I’m often asked by Mac users if they need a firewall. It’s a surprisingly difficult question to answer. Firewalls prevent unapproved connections to open ports on a computer or network, but the average Mac, by default, doesn’t open many ports in the first place. Leopard is a bit chattier than earlier versions of Mac OS X, but out of the box (at the time of this writing), there are no known attacks for these default services. But one security mantra is, “never assume,” and what’s true today won’t be true tomorrow. Drawing fire The future. WaterRoof ipfw firewall frontend. WaterRoof • uses Mac OS X built-in IPFW firewall.

Linux Demilitarized Zone (DMZ) Ethernet Interface Requirements and Configuration. Q. Can you tell me more about Linux Demilitarized Zone and Ethernet Interface Card Requirements for typical DMZ implementation?

How can a rule be set to route traffic to certain machines on a DMZ for HTTP or SMTP? A. Demilitarized zone, used to secure an internal network from external access. Sample Example DMZ Setup Consider the following DMZ host with 3 NIC: [a] eth0 with 192.168.1.1 private IP address – Internal LAN ~ Desktop system [b] eth1 with 202.54.1.1 public IP address – WAN connected to ISP router [c] eth2 with 192.168.2.1 private IP address – DMZ connected to Mail / Web / DNS and other private servers (Fig 01: A typical Linux based DMZ setup [ Image modified from Wikipedia article] ) Routing traffic between public and DMZ server To set a rule for routing all incoming SMTP requests to a dedicated Mail server at IP address 192.168.2.2 and port 25, network address translation (NAT) calls a PREROUTING table to forward the packets to the proper destination. ### end init firewall ..
