New Features in JUNOS Release 10.1 for SRX Series Services Gateways and J Series Services Routers
IDP now provides logging for application-level DDoS events. IDP generates three
types of application-level DDoS event logs: attack, state transition, and ip-action.
These event logs provide visibility into the application-level DDoS state and
provide notifications on occurrences of application-level DDoS attacks for each
protected application server.
[Junos OS CLI Reference, Junos OS Security Configuration Guide]
This feature is supported on SRX100, SRX210, SRX240, and SRX650 devices.
For branch SRX Series devices, BIOS is made up of U-boot and JUNOS loader.
Apart from this SRX240 and SRX650 also have U-shell binary as part of the
BIOS.
On SRX100, SRX210 and SRX240, there is support of Backup BIOS which
constitutes a backup copy of U-boot in addition to the active copy from which
the system generally boots up.
