Security

Security Settings

Security settings are locked by default. You need to click the lock in the bottom left corner and enter an administrator password in order to make changes.

Allow Rule Editing — If you have managed accounts (e.g. for your children) on your computer, you may want to forbid users to edit rules and profiles. When a connection alert is shown while rule editing is disabled, only temporary rules can be created.
Allow Profile Switching — Whether users may switch profiles even if rule editing is disabled. This option is irrelevant when rule editing is allowed.
Allow Settings Editing — Whether users may change settings. Useful if you have managed accounts (e.g. for children) on your computer. Users who have authorized as Administrator by clicking the lock may still edit settings or re-enable this option.
Allow Global Rule Editing — Whether users are allowed to create rules for Anyone. Since these rules affect other users, there is an option to prohibit their creation. Note, however, that System rules also affect other users and editing them must be allowed to all users.
Allow access via Terminal — Little Snitch comes with a Terminal command littlesnitch. In order to prevent malicious scripts from manipulating your firewall settings, most of the functions of this command are only available to the superuser and only if enabled here in the settings.
Hide my connections from other users — Decide whether Network Monitor may display domain and host details for apps running under your account to other users on the computer. Note that your apps may delegate tasks to system processes which service all accounts and are therefore visible to all users.
Allow GUI scripting access to Little Snitch — Whether it is allowed to remote-control Little Snitch. It is obvious that allowing remote control undermines some of the security gained by Little Snitch, but you may need it for third party screen sharing applications, assistive devices or similar.
