whats up youtube so today I want to talk to you guys about Little Snitch little
snitch is a network monitoring tool or firewall for mac OS and in my opinion it
is definitely the best firewall you can get for mac OS it's available here on
their website you can grab the latest version and the nightly version is also
working for mac OS Sierra
so if you guys are on the latest beta this program also work for you
you cannot purchase a full license from their website right now you can get it
for 3690 which includes micro switch which is a camera and microphone
monitoring tool as well so just to take a look here at Little Snitch
so we begin the task bar here with the network monitoring tool
this appears when you hover over and shows all the connections that are
currently running you can select individual e per connection you right
click you can also open up the general settings here as well if you go back in
here you can right click and open up the rules which are set for the firewall so
in your settings here you can actually turn the firewall network filter on or
off just by tapping the start filter on and off alerts are the alerts you get
when you're prompted from an application to access the internet usually shown
when the application first launches once it's added to the rules in your firewall
estate doesn't appear again
so we clear the rule for google chrome and we go to launch google chrome you'll
see here we're getting the alert that the settings was here in Little Snitch
so with this you can actually customize which connections that makes how long
that connection last so if you want it to last until you reboot
you can also get full details of the connection right here so you can see
everything about that connection
if we hit apply will be able to access the internet just like that
now if you have her back over you can see the connection beginning to download
as the video begins to play which you can use
the monitoring tool to monitor the connection in and out of your system so
you can see how much data is being used from which application in which IP it's
connecting to
so right now this video is playing in the background here and we can see that
chrome has spent a little bit of data out at us
so the next section here under settings is monitor and this is the Little Snitch
monitor that I first showed you here
you can customize if you'd like it to appear when you hover over the mouse or
not or if you'd like it to disappear automatically so that's just on personal
preference
there you can also change the color of the activity in the taskbar from a
grayscale to a color in the next menu here you can create profiles for
connecting the different networks so if you'd like to choose different settings
for different networks security and advanced have advanced rules in them for
customizing the firewall I would normally suggest to leave them alone and
then the update as well i would suggest leave it alone
you can see here a little snitch will snitch on itself and then huh
the last tab here is registration so I that would be like your license code
this will run for 30 minutes on a demo i believe so you can definitely try it out
first
alright so we've gone through some of the basics of setting up and settings
with the afternoon i'm going to show you guys the rule list
this is where you can get really advanced with your firewall here as you
can see every application any notification you've ever received from
Little Snitch will show up in here as a rule if it was specified as long-term
rule broken down to temporary rules you can see on the side less here on the
right column you can find a bunch of different rules that are broken down you
can see I have a couple of valid rules that i could clear out applications that
are no longer installed
you can customize the rules so if you highlight one and you go to the Edit
rule option you can see for example Google Chrome here we could change the
connection to deny from allow and if we were to run the application
it would not be able to access the internet so this is also word profiling
to come into place here you can change different profiles for different
networks using the Little Snitch
if you're on a certain Network where you don't want some applications to access
the internet and vice versa
so really cool if you see here we can change it back and then chrome will have
access to the internet again
so this is just a very basic example you can get in-depth with ports and specific
connections and everything so little snitch is a really in-depth powerful
firewall for the mac OS and it's one of the reasons i really like the software
here
so this is just another demo for you guys buy a set of video here to 1080p
you can measure the bandwidth that chrome is downloading the video and you
can see here I have a faster connection so downloads pretty quickly but you can
monitor the speed and again you can get the breakdown from all of the
connections there
you can also resize the network monitor
so it's a really handy tool easy to move around and so there you guys go that is
little stitch for mac OS i will finish the tutorial here showing a little
stitches built-in tutorial which is pretty informative and launches when the
app first launches since there's so much to Little Snitch
I would definitely advise if you download the app to take a good look at
this
you can react sit here just by going to the help and welcome to Little Snitch
so what do you guys think definitely let me know in the comments below
and we'll see you guys again next time
yeah
