Nightly Mac Port Scan for security (v9.0.2)
Today I realized I needed to check which ports were open on my Mac. It took me half an hour to find the command line utility that performs this check (it was well hidden). Then it took me another hour to design a solution that checks once each night for port changes and send myself an SMS with a tip that a change has occurred. All nightly scans are stored in a specific folder and if three consecutive scans provide identical results then the middle of the three is deleted.
I could have sent the details of the actual change in the SMS message, but I thought that was a little unneeded complexity. The details are easily observed in the portscans directory.
Some of the wizards on this forum may find problems or suggest improvements, but I think it's a pretty good utility, which helps you maintain security, and it's a good example of some of the usefulness of Keyboard Maestro. I intend to let this run every night on any Mac I own. I wonder what other ideas I could implement like this which may help track security issues. If you have any ideas let me know below.
