Connecting peripherals to your government Mac isn’t as simple as plugging in any device from Amazon. Federal security requirements mean only approved USB drives, keyboards, mice, and other accessories can be used. Here’s what you need to know about peripheral policies and approved options.
Why Peripheral Restrictions Exist
Government agencies restrict peripherals for several security reasons:
- Data exfiltration: USB drives can easily copy sensitive data
- Malware delivery: Infected devices can compromise systems
- Supply chain attacks: Counterfeit devices may contain hidden threats
- Unauthorized access: Wireless devices may be intercepted
- Compliance requirements: NIST and agency policies mandate controls
USB Storage Device Policies
Common Restrictions
Most government Macs have USB storage policies enforced through MDM:
- Personal USB drives blocked entirely
- Only encrypted, approved drives permitted
- Automatic mounting disabled
- File transfers logged and audited
- Certain file types blocked from transfer
Approved Encrypted USB Drives
When removable storage is authorized, agencies typically approve:
- IronKey: FIPS 140-2 Level 3 validated
- Kingston DataTraveler: Encrypted, government-certified models
- Apricorn Aegis: PIN-authenticated encryption
- Kanguru Defender: FIPS certified options
Check with your IT security team for your agency’s specific approved product list (APL).
Using Approved USB Drives
- Obtain an approved drive from your IT department
- Register the drive with your agency’s asset management
- Follow encryption and PIN setup procedures
- Only transfer authorized, unclassified data
- Report lost or stolen drives immediately
Keyboards and Mice
Wired Peripherals
Wired USB keyboards and mice are generally permitted with fewer restrictions:
- Standard USB keyboards usually allowed
- Gaming keyboards may be blocked (macro functions)
- USB mice typically unrestricted
- USB hubs may require approval
Wireless Peripherals
Wireless devices face more scrutiny:
- Bluetooth: Often permitted for keyboards/mice
- RF wireless: May be restricted due to interception concerns
- Agency-issued: Preferred over personal devices
Recommended Peripherals
Common government-approved options include:
- Apple Magic Keyboard and Magic Mouse/Trackpad
- Logitech MX series (check specific model approval)
- Microsoft ergonomic keyboards
- Standard wired USB keyboards and mice
CAC/PIV Card Readers
Smart card readers are essential for government Mac users:
Approved CAC Readers
- SCR3310v2.0: USB-A, widely supported
- SCR3500: Compact, ExpressCard-compatible
- Identiv uTrust 3700F: USB-C compatible
- HID Omnikey: Various models approved
CAC Reader Setup on Mac
- Connect the approved reader to your Mac
- macOS recognizes most readers automatically
- Insert your CAC card chip-side up
- Install DoD root certificates if not already present
- Test by accessing a CAC-enabled website
Monitors and Docking Stations
External Displays
External monitors are typically permitted:
- USB-C/Thunderbolt displays connect directly
- HDMI displays may need adapters
- Verify display doesn’t have built-in USB hub if USB restrictions exist
Docking Stations
Docking stations require more consideration:
- Agency-issued docks preferred
- Thunderbolt docks may require approval
- USB-C docks vary in approval status
- Network-enabled docks face additional scrutiny
Webcams and Microphones
Built-in vs External
Your MacBook’s built-in camera and microphone are approved. External devices:
- May require approval for sensitive areas
- Should be disconnected when not in use
- Agency-issued options preferred for classified spaces
Video Conferencing Equipment
For better video meetings:
- Logitech webcams often approved
- USB headsets with microphones common
- Check conference room equipment policies
Printers and Scanners
Direct USB printer connections:
- Generally permitted for approved devices
- Network printing preferred
- Personal printers may be restricted
- Scanners may require approval (data capture concerns)
What’s Typically NOT Allowed
- Personal USB flash drives
- Unencrypted external hard drives
- USB devices from unknown sources
- Devices purchased without IT approval
- Promotional USB items (conference giveaways)
- Devices with built-in WiFi capabilities
- Arduino, Raspberry Pi, or development boards
Reporting Found Devices
If you find an unknown USB device:
- Do NOT plug it into any computer
- Report it to your security officer
- Note where it was found
- Let security handle analysis
Unknown USB devices are a common attack vector. Even devices left in parking lots could be malicious.
Getting Peripherals Approved
If you need a peripheral not on the approved list:
- Submit a request to your IT department
- Explain the business need
- Provide product specifications
- Wait for security review
- Purchase only after approval
Following peripheral policies protects your agency’s network and data. When in doubt, ask your IT security team before connecting any device to your government Mac.
