FireSIGHT User Agent Configuration Guide
 
Chapter 1      Introduction 
  Understanding User Agents
In addition, if you are planning to implement user access control, you must set up a connection to each 
Microsoft Active Directory server where you plan to collect data, with user awareness parameters 
configured.
User Data Collection Limitations

The following table describes the limitations of user data collection, either generally or as they 
specifically relate to agents.
Table 1-1
User Data Collection Limitations 
Limitation
Description
user control
To perform user control, your organization must use Microsoft Active 
Directory LDAP servers. The system obtains the users and groups you can use 
in access control rules from Active Directory, and also ties users to IP addresses 
with the logins and logoffs reported by User Agents installed on Active 
Directory servers.
login detection
The agent reports user logins to hosts with IPv6 addresses to Defense Centers 
running Version 5.2+.
The agent reports non-authoritative user logins and NetBIOS logins to Defense 
Centers running Version 5.0.1+.
The agent reports authoritative logins from actual user names to Defense 
Centers running Version 4.10.x+.
If you want to detect logins to an Active Directory server, you must configure 
the Active Directory server connection with the server IP address. See 
 for 
more information.
If multiple users are logged into a host using remote sessions, the agent may 
not detect logins from that host properly. See 
 for more information on how to prevent this.
logoff detection
The agent reports detected logoffs to Version 5.2+ Defense Centers.
Logoffs may not be immediately detected. The timestamp associated with a 
logoff is the time the agent detected the user was no longer mapped to the host 
IP address, which may not correspond with the actual time the user logged off 
of the host. 
Logoffs are generated by the agent itself when it detects a user logged out of a 
host IP address. Logoffs are also generated when the agent detects that the user 
logged into a host has changed, before the Active Directory server reports that 
the user has changed.
real-time data 
retrieval
The Active Directory server must be running Windows Server 2008 or 
Windows Server 2012.
