Installation Options

1. Install with pip

   • $ pip install stronghold
   • $ stronghold

2. Download the stronghold binary from Releases tab.

Configuration Options

1. Firewall

   • Turn on Firewall?
     • This helps protect your Mac from being attacked over the internet.
   • Turn on logging?
     • If there IS an infection, logs are useful for determining the source.
   • Turn on stealth mode?
     • Your Mac will not respond to ICMP ping requests or connection attempts from closed TCP and UDP networks.

2. General System Protection

   • Enable Gatekeeper?
     • Defend against malware by enforcing code signing and verifying downloaded applications before allowing them to run.
   • Prevent automatic software whitelisting?
     • Both built-in and downloaded software will require user approval for whitelisting.
   • Disable Captive Portal Assistant and force login through browser on untrusted networks?
     • Captive Portal Assistant could be triggered and direct you to a malicious site WITHOUT any user interaction.

3. User Metadata Storage

   • Clear language modeling metadata?
     • This includes user spelling, typing and suggestion data.
   • Disable language modeling data collection?
   • Clear QuickLook metadata?
   • Clear Downloads metadata?
   • Disable metadata collection from Downloads?
   • Clear SiriAnalytics database?

4. User Safety

   • Lock Mac as soon as screen saver starts?
   • Display all file extensions?
     • This prevents malware from disguising itself as another file type.
   • Disable saving documents to the cloud by default?
     • This prevents sensitive documents from being unintentionally stored on the cloud.
   • Show hidden files in Finder?
     • This lets you see all files on the system without having to use the terminal.
   • Disable printer sharing?
     • Offers redundancy in case the Firewall was not configured.
