Photoshop CC: Firewall rules for minimum services & connections required to function?

Hello,

Long time users of Photoshop desktop, and new users testing this "Creative Cloud" version. We are privacy minded so would appreciate if someone can explain the following...

So far our firewall has picked up these Adobe CC services trying to make outbound connections:

- LogTransport Application ( logtransport2.exe )
- Evented I O for V8 JavaScript ( node.exe )
- Creative Cloud ( adobe desktop service.exe )
- Core Sync ( coresync.exe )
- Adobe Photoshop CC 2015 ( photoshop.exe )
- Adobe License Utility ( adobe_licutil.exe )
- Adobe GC Client Application ( adobegcclient.exe )
- Adobe Creative Cloud ( creative cloud.exe )
- Adobe CEP HTML Engine ( cephtmlengine.exe )

Is there somewhere online where we can read about the purpose of each of these, how they are triggered, how (and if) they can be disabled? In addition, we're in California. Is there somewhere that we can read specifically what data and/or files are collected from our user environment and send back to Adobe?

I have tried working offline with all services above blocked - Photoshop launched but it crashed when I tried to open a PSD file.

Can you tell us what bare minimum services above are required for Photoshop CC to function properly? We don't mind opening up temporarily, occasionally, to allow re-verification of active subscription/license.

Thanks,
JG

Also I just noticed something. In this "Creative Cloud" preferences pane that runs in the system tray, it seems by default Adobe helps itself to a default configuration allowing it to sync everything in the users root directory to the "Creative Cloud" -- by default it seems to have enabled itself to sync C:\Users\username

I'm a bit lost for words here.

Here are some documentation on the various connections/ports/URLs used by Creative Cloud:

Are you an enterprise organization? There's a couple of ways to disable services depending on your licensing.

Hi Jeffrey,

Thanks for the quick & helpful response.

We are not a large enterprise organization. Can only enterprise organizations disable unnecessary network communication? If I am an individual, or a small business, can I disable the unnecessary communication and still have a functional product from Adobe, too?

Sure.

In Photoshop, go to Preferences>General... and disable the welcome screen with "Do not show Welcome Screen on launch"
Go to Preferences>Plug-ins and uncheck "Enable Generator," "Allow Extensions to connect to the internet" & "Load Extension Panels"

Next, click the Gear in the upper left of the Creative Cloud desktop app and select Preferences and go to the File tab to turn Sync off, got to the Fonts tab to turn Typekit off. You can also prevent the CC app from launching at log-in in the general tab.

Enterprises have a little easier time using a dashboard for maintaining connected services for thousands of seats.

Hi, Jeff,
I'm opening a PDF that I just downloaded (http://bibliotecadigital.tamaulipas.gob.mx/archivos/descargas/66e46ea44_rosa.pdf), and I see "adobe gc client application" trying to communicate out. I do not see in the Preferences of my Acrobat Pro X any options about this.
Can I disable this communication in my firewall (Eset), or, more friendly, in Acrobat itselt?
Thanks,
Ricardo.

This site only supports the  Photoshop family of products. We don't know what Acrobat needs/wants, so you might be better off asking in the Acrobat user forums.

Jeffrey,

Fantastic! Thanks. It seems as if the first PSD I opened (where it crashed) may have been a fluke. I have blocked all services for now and everything seems to be working. I've also taken the steps you suggest above, so I imagine it will be less "chatty" as a result.

Thanks for your time.

Ok. Let me know if you hit any other processes. I can try and figure out which one it is and help you disable it.

Jeffrey,

In the interest of having a complete list of processes associated with Photoshop CC that want to use the internet, I found a couple more services that have popped up:

- Adobe Update Service ( adobeupdaterservice.exe )
- AAM Updates Notifier Application ( aam updates notifier.exe )

As far as I know I have update checking disabled per your suggestion above.

I'm only about 24 hours into use like this (blocking outbound access to these 11 services)

I've had it hard crash on me once more while working, but not sure why. If it happens more I'll probably try to find some logs or log a session with process explorer to see what it's trying to do before the crash.

Thanks

Those are processes of updater/creative cloud app. Is the CC app still running?

In the systray area? Yes, it just says "No Internet Connection". But I have already created a taskbar link directly to Photoshop, so no issues launching.

I imagine eventually the offline mode is going to want/require to phone home to verify licensing. Hopefully that's just going to be quick once-a-month connection for adobe_licutil.exe.

If that's all I need to do, I'll be happy :)

That's correct. Every 99 days you will need to connect to reactivate. I would set the Creative Cloud app not to launch on log-in.
