The user identity (username) of the currently logged in user on the host. 

Note that 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. In addition, when a non-authoritative user is the current 
user on a host, that user still cannot be used for user control.

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 servers that are running on monitored hosts by using one of the predefined 
searches or by using your own search criteria. The predefined searches serve as examples and can 
provide quick access to important information about your network. 

You may want to modify specific fields within the default searches to customize them for your network 
environment, then save them to reuse later. The fields you can use to retrieve data are described in 

.

When searching for servers, you should keep in mind that although you can configure the network 
discovery policy to add applications, including servers, to the network map based on data exported by 
NetFlow-enabled devices, the available information about these servers is limited. For more information, 
see 

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. 

For detailed information on search syntax, including using objects in searches, see
