For User Login activity, the IP address involved in the login, which can be an IP address of the user’s 
host (for LDAP, POP3, IMAP, and AIM logins), the server (for SMTP and Oracle logins), or the 
session originator (for SIP logins).

Note that an associated IP address does not mean the user is the current user for that IP address; 
when a non-authoritative user logs into a host, that login is recorded in the user and host history. If 
no authoritative user is associated with the host, a non-authoritative user can be the current user for 
the host. However, after an authoritative user logs into the host, only a login by another authoritative 
user changes the current user.

For other types of user activity, this field is blank.

For Delete User Identity and User Identity Dropped activity, the username of the user who was 
deleted from the database or failed to be added to the database. For logins to network resources, 

network login

 is displayed. For other types of user activity, this field is blank.

For user activity detected by a managed device, the name of the device. For other types of user 
activity, the managing Defense Center.

The number of events that match the information that appears in each row. Note that the Count field 
appears only after you apply a constraint that creates two or more identical rows.

FireSIGHT

You can search for specific user activity. You may want to create searches customized for your network 
environment, then save them to reuse later. 

The system displays examples of valid syntax next to each search field. When entering search criteria, 
keep the following points in mind:

All fields accept negation (

!

).

All fields accept comma-separated lists. If you enter multiple criteria, the search returns only the 
records that match all the criteria.

Many fields accept one or more asterisks (

*

) as wild cards.

For some fields, you can specify 

n/a

 or 

blank

 in the field to identify events where information is not 

available for that field; use 

!n/a

 or 

!blank

 to identify the events where that field is populated.

Most fields are case-insensitive.

IP addresses may be specified using CIDR notation. For information on entering IPv4 and IPv6 
addresses in the FireSIGHT System, see 

.

Click the add object icon (

) that appears next to a search field to use an object as a search 

criterion.
