Apple Remote Desktop 3.9 Apple Remote Desktop is the best way to manage the Mac computers on your network. Distribute software, provide real-time online help to end users, create detailed software and hardware reports, and automate routine management tasks—all without leaving your desk.
Little Snitch is a host-based application firewall for macOS. It can be used to monitor applications, preventing or permitting them to connect to attached networks through advanced rules. It is produced and maintained by the Austrian firm Objective Development Software GmbH.
Unlike a stateful firewall, which is designed primarily to protect a system from external attacks by restricting inbound traffic, Little Snitch is designed to protect privacy by limiting outbound traffic.[2] Little Snitch controls network traffic by registering kernel extensions through the standard application programming interface (API) provided by Apple.[3]
If an application or process attempts to establish a network connection, Little Snitch prevents the connection. A dialog is presented to the user which allows one to deny or permit the connection on a one-time or permanent basis. The dialog allows one to restrict the parameters of the connection, restricting it to a specific port, protocol or domain. Little Snitch's integral network monitor allows one to see ongoing traffic in real time with domain names and traffic direction displayed.
The application (version 4) received a positive 4.5/5 review from Macworld.[4]

My iMac was hacked into several months ago and after doing everything humanly possible to get rid of the malware that was on my harddrive Im still a little gun shy so Im constantly looking for abnormalities in my file system. Yesterday I checked my Firewall and Apple File Server configurations.
The files below are whats being allowed to get through my firewall settings. I realize that bonjour is one of the files that has permission but I've read parts of the discoverd (bonjour) file and there was some things in the file that increased my concern enough to create this post.

I have never set my computer up to do any kind of sharing but apparently python, ruby, javajdk, Apple File Server, Printer Sharing, Remote Login - SSH and Samba Sharing all have exclusive authorization. I've enable Stealth in my Firewall but according to the config file Stealthenabled is disabled (0).
Like I said I have never set my computer up to be a server but it appears that Apple File Server configuration says other wise. What confuses me about this file the very first line says its disabled but I've seen it running in my activity monitor and Enabled Transactions are allowed
