Hi, I'm hearing a lot of people talk about firewalls and how a firewall that is not properly secured might as well not exist because hackers can still get through. Now, I'm also hearing about SonicWALL (Insanely-Great.com) and their firewall system to create Virtual Private Networks (VPNs). The latter sounds very cool. http://www.insanely-great.com/news.php?id=1562 However, ignorant as I am about firewalls, and internet security, I was wondering the following: 1.) Is there online documentation about how to secure a firewall on OSX? And does it matter which version of OSX you might have? And if so, what sort of issues each version poses? 2.) Is there any sort of online documentation that Mac Users have culled together to help other Mac users to help protect their macs? I'm thinking since there are so many smart people on this site that perhaps there might be a gathering of minds (so-to-speak) in some quadrant of the internet where this knowledge is shared to the benefit of all Mac people. If not, I think it would be really empowering for the Mac community to look after its own security needs by helping each other out. Please share your views on this. Thanks again for all your help!
