Juniper Js Screen Monitor Port Scan

1.3.6.1.4.1.2636.3.39.1.8.1.1.1.1.12

A port scan occurs when one source IP address sends IP packets containing TCP SYN segments to a defined number of different ports at the same destination IP address within a defined interval. The purpose of this attack is to scan the available services in the hope that at least one port will respond, thus identifying a service of the target. The device should internally log the number of different ports scanned from one remote source. This attribute records the port scan attempt attack packets.
