Getting started

This document explains how to enable or disable the Secure Boot feature in the UEFI on SNS firewalls. This feature strengthens the security of the system, in particular by verifying the signature of the system that was loaded when the firewall started up.

Before enabling Secure Boot:

• For security reasons, you are advised to protect your firewall's UEFI control panel with a password. For more information, refer to the technical note Protecting access to the configuration panel of the UEFI on SNS firewalls,

• Do note that you can no longer perform the following operations on your SNS firewall after you enable Secure Boot:

  • Reset the administrator password in single user mode,

  • Start the SNS firewall on a backup partition in a version of SNS lower than 4.2.1,

  • Start the SNS firewall on a USB key when restoring the program via USB key (USB Recovery),

  • Install a version of SNS lower than 4.2.1.

This procedure applies to the following firewall models: SN-XS-Series-170, SN-S-Series-220, SN-S-Series-320, SN-M-Series-520, SN-M-Series-720, SN-M-Series-920, SN1100, SN-L-Series-2200, SN3100, SN-L-Series-3200, SN-XL-Series-5200, SN-XL-Series-6200, SNi10 and SNi20.
