Mac OS 10.5.1 Update - Security Changes
I’m sure the 10.5.1 update (which just rolled out to Software Update today) will be dissected on all of the Mac forums and blogs, but in the Security section of the release notes, there are a few highlights that were noteworthy:
- The “Block All Incoming Connections” setting I talked about here has now been changed to read “Allow only essential services.” Without having installed it yet, I believe that’s still going to mean ‘anything running as root, plus the MDNS and a few other things.’
- Another change to the Application Firewall related to code-signing and parental controls
- Patches for all of the recent security issues.
There are a few other things I’ll need to look at later tonight, but this is a start. I’ll do some of the netcat testing again to verify the firewall change item.
