Overview
This guide provides information for installing and configuring the Trend
Micro™ TippingPoint™ Identity Agent in a Windows environment (Windows
Server 2008, 2008 R2, 2012, 2012 R2, 2016, and 2019).
Once configured, the Identity Agent will poll the Active Directory domain
controller to collect user account and user group information. The Identity
Agent will also poll the domain controller for security login events.
Once the SMS is configured to poll the Identity Agent, the SMS will display
the User ID to User IP correlation and security login events.
You can configure the Identity Agent to:• Connect to one or more domain controllers to poll user login
information.
• Change the default user/group and security log connection settings.
• Enable secure LDAP.
• Map or exclude IP addresses.
• If you customized your Active Directory schema, you can match thesame schema in the Identity Agent.

Microsoft Kerberos is an integral part of an Active Directory implementation.
Kerberos provides secure user authentication that permits interoperability.
The Active Directory domain controller maintains user account and log-in
information to support the Kerberos service.
The Identity Agent depends on Kerberos protocol being used in the Active
Directory authentication process. To make use of Kerberos, you must add
Kerberos to your Active Directory Server.

Important
To secure your environment against POODLE, disable SSLv3 in the Windows
OS where the Agent will be installed. For assistance, contact Microsoft.

Create a new Active Directory user
Use Active Directory Users and computers to create a new user account. This
user account will be used for running the agent service and connecting to thedomain controllers.

Assign permissions for the Active Directory user
If you do not have administrative credentials, you must assign certain
permissions to allow the Active Directory user to perform specific actions,such as connecting to the Identity Agent.
Before you begin
If you have administrative credentials, skip this procedure, as the user
already has these permissions assigned by default.
As a security best practice, consider using Run as Administrator to perform
this procedure. This procedure must be preformed on the domain controller.

8.

Click Apply.

9.

Repeat this procedure in all domain controllers that are configured in
the Identity Agent.

Windows Firewall
Windows Firewall with Advanced Security allows you to require thatcomputers authenticate before communicating with the Identity Agent.
From here, you must:• Enable predefined firewall rules to activate the rule and allow the user toconnect to the Identity Agent through Windows Firewall.
• Create a new rule to allow a connection based on the TCP port number
over which the computer is trying to connect to the Identity Agent. You
can specify more than one port number. The port numbers will display
in the Agent Port field in the Identity Agent.

Identity AgentThe Identity Agent keeps track of specific groups based on IP address withthe goal of maintaining Identity Management and efficiently enforcing user
policies.
The Identity Agent adds another layer of network policy refinement by using
Active Directory (AD) of users and user groups. Through its interaction withan AD domain controller, the Identity Agent enables SMS administrators tokeep track of specific users and groups based on IP address. The Agent
constantly polls the security logs of the AD domain controller--at a rate of
every four to five seconds for security login events and every 15 minutes for
metadata and diagnostics--and communicates this information to the SMS.
With this degree of visibility for the SMS, administrators can target policies
according to, for example, an engineering group vs a marketing group. The
service is most useful in environments where control and visibility are ahigher priority than filter management.
This enables the SMS to determine the IP address of any user/group.

Identity Agent configuration
Identity Agent configuration is the Identity Agent component where the you
configure the agent, manage domain controllers, set connection settings,
and maintain a list of mapped or excluded IP addresses.
The following table describes the main areas of the Identity Agent interface
is divided into four main areas.
Field
Agent Host IP

Description
Displays all available IP addresses. Once you select an IP addressand click save, this field will be unavailable. If you want to select a
different IP address, you must uninstall and reinstall the Identity
Agent.

15

Identity Agent User Guide

Field

Description

Agent Port

The port in which the Identity Agent will communicate with the
SMS. Remember that this port must also be the port that is open in
the Windows Firewall.

Domain Name

The domain name that the Identity Agent is connected to.

Base DN

The distinguished name of the node in the active directory underwhich all users and groups are located.

Domain Controller
IP Address

The IP address of the domain controller. You can have up to 30
domain controllers, but remember that the first one entered will be
the primary domain. If you want to set a different primary domain
controller, you must remove all IP addresses from the list, and thenreenter the IP address or hostname.

Connection Settings
User/Group Poll

The amount of time that the Identity Agent will poll the user andgroup information. The default frequency of is every 15 minutes.

Security Log Poll

The amount of time that the Identity Agent will poll the login
security events. The default frequency is every four to five seconds.

Secure LDAP

Determines whether the LDAP is secure.

Mapped IPs

Displays a list of correlated, or permitted, IP addresses. You can add
an individual IP address, a range, or a CIDR. If the list is blank, theIdentity Agent will correlate all IP addresses.

Excluded IPs

Displays a list of values that you do not want to correlate from the
Identity Agent.

Custom Schema

If you customized your Active Directory schema, you can match thesame schema in the Identity Agent.

Identity Agent issues and resolutions
This document covers the agent issues found during pre-installation,
installation, and post installation as well as the steps required to resolvethese issues.

Agent service not able to query domain controller security log
eventsIssue
The agent service is not able to query domain controller security log events.
Root cause
The Identity Agent service logon user does not have sufficient privileges in
the active directory (AD) to access security log events.
Resolution
To resolve this problem, verify in the AD that the Identity Agent service logon
user account has the following group membership:• Domain Users(OR)• Distributed COM Users• Event Log Readers• Performance Monitor Users
If it doesn't have the correct membership, then it should be added.
The image below shows an example of adding a group membership to a user
account.

Agents may not function properly without a SMS 2k Certificate
Key while TLS v1.2 is enabled.

Root cause
TLS v1.2 requires a 2K key, and the SMS has only a 1K key.
