Secure Your Hardware: The Foundation of Cyber Resilience

Hardware is often overlooked in cybersecurity, but it’s the bedrock of your defences.  Weak or unprotected devices open the door to attackers, while strong hardware controls give you fewer entry points, better endpoint control, and a safer base for everything else.

Top Tips for Securing Hardware:

1. Choose Trusted Devices

   • Buy hardware from reputable vendors with verified firmware.

   • Ensure devices support modern security features (e.g., TPM, Secure Boot).

2. Lock Down BIOS/UEFI Settings

   • Set a strong password for BIOS/UEFI to prevent tampering.

   • Enable features like Secure Boot and disable legacy boot options.

3. Disable Unused Ports & Interfaces

   • Switch off unused USB, FireWire, or SD ports in BIOS/UEFI.

   • Restrict or monitor USB device use to avoid rogue storage or malware.

4. Physically Secure Systems

   • Use cable locks for laptops and secure racks for servers.

   • Restrict access to network hardware (routers, firewalls, switches).

5. Enforce Device Policies

   • Require encryption on all laptops and portable devices.

   • Block personal or unapproved hardware from connecting to the network.

6. Control Peripheral Use

   • Deploy endpoint protection tools that can whitelist or block USB devices.

   • Educate staff on the risks of plugging in unknown devices.

7. Harden Endpoint Configurations

   • Apply OS hardening guides (CIS Benchmarks, vendor security baselines).

   • Remove unnecessary pre-installed apps (“bloatware”) that add risk.

8. Monitor & Audit Hardware Regularly

   • Keep an inventory of all business devices.

   • Replace outdated or unsupported hardware promptly.

Remember: A single unprotected device, or one rogue USB stick, can undo your entire cybersecurity strategy.  Secure the foundation, and every layer above it becomes stronger.
