End of Life Procedures
The restore to factory defaults option should also be used as part of the end of life procedure when a
NetDefend Firewall is taken out of operation and will no longer be used. As part of the
decommissioning procedure, a restore to factory defaults should always be run in order to remove
all sensitive information such as VPN settings.
As a further precaution at the end of the product's life, it also recommended that the memory media
in a NetDefend Firewall is destroyed and certified as destroyed by a suitable provider of computer
disposal services.
Warning: Do NOT abort a reset to defaults
If the process of resetting to factory defaults is aborted before it finishes, the
NetDefend Firewall can then cease to function properly with the complete loss of all
stored user data.
