Macintosh Security Basics - Presentation Notes

Connecting with 10.2

Choose a realm, and X detects and displays available servers. Or, type the address manually and hit Connect. Or, select from Favorites (top popup menu, it bookmarks your most recent servers). In Jaguar (10.2), you can even browse SMB shares!

Connecting to other servers

Once you’ve picked the server you want to connect to, the next box should look familiar:
This part of the process is pretty similar to the equivalent under old MacOS. One thing that I find rather lacking is that you have to hit the Options button to see what kind of password encryption is being used. But, you can also set a preference to tell you when you’re about to send your password in clear text, which is a step up from the OS 9 version.

Firewalling on OS X

OS X’s built-in firewall is ipfw. By default, allows anything. :( There are a couple of good GUIs for it. Brickhouse!
Ipfw can be administered from the command line, but there are a couple of terrific front end programs for it. Brickhouse, by Brian Hill (who’s written a heap of good security apps for OS X) is $25 shareware. It’s well worth it. Brickhouse has a built-in assistant feature to help guide you through creating a set of firewall rules, or you can make your own. It even has Expert Mode, which displays the actual ipfw config file and lets you edit that directly. Use drag and drop to re-order rules. It has logging in human-readable format. It’s great.
