This KB explains what is secure boot and supportability on QFX5200 Series Platforms

Article provides details on supportability on QFX5200 Series Platforms

Secure Boot is a security feature implemented in Juniper Networks devices to protect against unauthorized firmware modifications.
It's designed to ensure the integrity and authenticity of the software running on the device.  
 
How it works:

• Secure Flash: The process begins with Secure Flash, which prevents unauthorized changes to the firmware.  

• Digital Signatures: Authorized Juniper OS releases carry digital signatures, verifying their authenticity.

• Chain of Trust: Each component in the boot process verifies the next, ensuring the integrity of the entire chain.

• Protection: Protects against firmware-based persistent threats.  

 
Key Benefits:

• Integrity: Ensures that the system is running trusted software.

• Reliability: Reduces the risk of system failures caused by corrupted firmware.

 
Implementation:

• Enabled by default: Secure Boot is typically enabled by default on supported Juniper platforms.

• No user intervention: Generally, no user configuration is required.  

Additional Details:

• UEFI 2.4 standard: Juniper's Secure Boot implementation is based on this standard.  
  BIOS hardening: The BIOS is strengthened to serve as a root of trust.  
  Cryptographic protection: BIOS updates, bootloader, and kernel are protected using cryptography.

On QFX5200 Series platforms, Secure boot is only supported on QFX5200-48Y platform and it is not supported on QFX5200-32C platform which is because QFX5200-32C can not support Secure image.
