Little Snitch is made by German based developers Objective Development and easily the slickest and most user-friendly commercial network monitoring software for Mac users. The great thing about Little Snitch is that it not only monitors but also protects your network with its own Firewall. The Little Snitch Research Assistant says that parsecd is 'Used for Suggestions in Spotlight, Messages, Lookup and Safari and usually connects to api.smoot.apple.com.' I believe the one that deals with the Universal Clipboard might be keyboardservicesd, but looking online there seems to be no real answer to what keyboardservicesd actually does.

I've used PCs since the early 1980s, but I am puzzled on how to strategically configure little snitch. I don't understand the bewildering number of ports - so how, when and why should I block any of them? Why are they used, when, for what purposes, by which programs? i don't understand how to tell when a program is attempting to transmit information for a valid reason, versus attempting to do so for some nefarious purpose.. so I don't know how or why to agree or not to agree to allow any particular program to do so. I basically don't understand the 50 thousand ways that computer programmers have devised to surreptitiously spy on everything we do online, and/or attempt to steal our information or use us as their data-mining stooges. The instructions for Little Snitch are woefully inadequate because there are no examples to follow. I can only learn from real-world examples. Without examples, all I have is a manual that tells a lot of HOWs but fails to show any WHYs. Am I the only person who feels this way? Is there more information, somewhere, that I have not discovered, that explains this better? Little Snitch is a great little utility, but I feel that it deserves better instructional support.

Little snitch Rule set(s)

Installation:

What Is Netbios Little Snitch Game

  1. Open Littledsnitch config
  2. Place hot_pocket in wave: do
  3. cook on high for 2.5 min
  4. click import rules (where applicable i.e. 'all over')

That's not necessarily true. The article mentions this. While ObDev still doesn't have all the APIs necessary to implement all the features of Little Snitch using NetworkExtensions, they are working on it with Apple and feature-parity is not expected to be an issue for the 10.16 release. Oct 19, 2009  I have Little Snitch running on my Mac, and I notice most of the programs that are soliciting connections are those I have seen before, but some I'm still wondering what they're exactly doing. 'DirectoryService' connects to 192.168.2.1 (I'm on a wireless router, if this helps). 'Finder via nmblookup' was connecting to: 192.168.2.255.

Theory / Mechanics / General Thoughts

Litle snitch has some really amazing features, namely, auto profile switching for different networks.

I always begin with setting a 'deny connections' for everything, then, allowing what I need. It took me a long time to figure this part out. This will save you from having a pop up every goddamn second when you fire this baby up.

When you import these rules you'll most certainly have applications that I don't and vice versa. You will see this expressed in the approprate menu on the left side of the Little Snitch config.

This set is nowhere near finished but it's a great starting point for someone to 'train' their own firewall. My general 'rule of thumb' (sorry ladies) has been to adhere to the rule of least permissions. This is great in theory but unfortunately in the real world it becomes extrememly annoying to approve rules on a domain by domain basis. So, I have been training the snitch via Port and Protocol and not the full-on, super annoying, domain based rules.

Rules and Profiles

Profiles:

  • Home
  • Obviously, home network with very permissive rules.
  • Hotspot
  • This one is a work in progress as I rarely use 'hotspots'
  • iPoop (iPhone)
  • This is similar to the Hotspot but should be used with a 'trusted device'
  • Public
  • Super strict ruleset for public networks.
  • Public +
  • Similar to Public but a bit more permissive in order to get work done.
  • Vadded (VPN)
  • I used mullvad as my preferred VPN provider for a long time. Now, I configure my own VPN's through digital ocean. The idea is the same either way, because of encryption, we can use this as the permissive set.
