jnxJsScreenUdpSweepThresh
Module: JUNIPER-JS-SCREENING-MIB
OID (symbolic): JUNIPER-JS-SCREENING-MIB::jnxJsScreenUdpSweepThresh
OID (numeric): 1.3.6.1.4.1.2636.3.39.1.8.1.1.3.1.2
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: The UDP sweep threshold interval is in microseconds. The default threshold value is 5000. The valid threshold range is 1000-1000000.
By using the default settings, if a remote host has UDP connection to 10 addresses in 0.005 seconds(5000 microseconds), the security device flags this as an UDP sweep attack, and rejects all further new UDP connections from that host for the remainder of the specified threshold time period.
This attribute holds the UDP sweep attack threshold.
What is jnxJsScreenUdpSweepThresh?
This read-only value reports the configured UDP-sweep detection interval in microseconds (default 5000, valid range 1000-1000000): a source contacting 10 addresses over UDP within this interval triggers the sweep defense, which then rejects further new UDP connections from that source for the timeout period. An admin reads this to understand how aggressive a horizontal UDP scan has to be before the zone's sweep protection kicks in.
