DDC Agents
This document provides procedures for installing and upgrading Agents in the Operating Systems required by your Data Stores. Agents should always be upgraded to be aligned with the latest server version. To upgrade an Agent, simply re-install it. Before reinstalling, you have to uninstall the older version of the Agent.
Note
As of this release, most Agents without the database runtime component will not be supported. If you have any affected Agents installed without the database runtime component, you have to upgrade them to the database runtime version.
Download the DDC Agents ZIP file corresponding to the CipherTrust Manager version from the Thales Customer Support Portal.
Check the Agent Compatibility Matrix to find a matching Agent to the desired Data Stores.
Extract the Agent Installer Package from DDC Agents ZIP and save it on the host machine where you want to install the Agent.
Follow the appropriate procedure for your Operating System.
Tip
Before you begin the installation, make sure that CipherTrust Manager is reachable from the host where you are installing the Agent.

DDC supports two types of Agent configurations:
Local: Agent is installed and configured directly on the machine that contains sensitive data. Agent completes the scan accessing the files directly from the file system.
Proxy: Agent is installed and configured on a proxy machine that is used to scan sensitive data on other machines. Agent completes the scan accessing the information stored in the data store using the configured port and protocol. Please note that a proxy Agent can be installed on the same host as an in-house data store.
The instructions to install and configure Agents in both types of configurations are the same.
Note
- To connect to databases you require an Agent with DB runtime. If you have any Agents without DB runtime, please upgrade them to the ones that are included in this release.

Installing Agents on RHEL
To install the Linux 3 database runtime Node Agent on RHEL:
Install the epel-release package:
sudo yum install epel-release
Install the required packages:
sudo yum install libxml2 libgsasl openssl \ libcurl libuuid protobuf krb5-libs libaio
Navigate to the location where the Agent installation package (.rpm) is stored.
Install the Agent by using the following command:
sudo rpm -ivh er2-2.x.x-linux3-rh-x64_database-runtime.rpm
For example:
rpm -ivh er2-2.6.0-linux3-rh-x64_database-runtime.rpm
Connect the Agent to the active CipherTrust Manager node:
er2-config -i <hostname|ip_address>
where,
<hostname|ip_address>
represents the IP address or hostname of the CipherTrust Manager node.Test the connection settings (on the data store that is using this host).
er2-config -t
If the connection has been correctly configured, you should see the following message:
Testing connection setting... Test SUCCESS. Saving settings Configuration updated, please restart agent service The configuration has been saved. Please restart the agent for the changes to take effect.
To be able to scan Oracle DB Data Stores, make sure that the agent can resolve its own hostname. If it cannot, add it to its hosts file. For example, if its hostname is 'agent123', add this line:
Tip
127.0.0.1 localhost agent123
Restart the Agent:
Option 1
sudo /etc/init.d/er2-agent restart
Option 2
sudo /etc/init.d/er2-agent stop sudo /etc/init.d/er2-agent start
Note
The installation script creates an erecon
user in the erecon
group. Please ensure that this user (or group) is able to read all the files to scan. For security reasons, the account has its password locked to ensure that the user is solely used by the Data Discovery and Classification scanning agent.
Uninstalling Agents from RHEL
To uninstall a DDC Agent:
Stop the DDC Agent.
sudo /etc/init.d/er2-agent stop
Remove the existing packages:
sudo rpm -e er2

sudo er2-config -i <hostname|ip_address>
where
<hostname|ip_address>
represents the IP address or hostname of the CipherTrust Manager node.Test the connection settings (on the data store that is using this host).
sudo er2-config -t
If the connection has been correctly configured, you should see the following message:
Testing connection setting... Test SUCCESS. Saving settings Configuration updated, please restart agent service The configuration has been saved. Please restart the agent for the changes to take effect.

Click Finish to complete the configuration.
After a successful Agent installation, click the Finish button to exit the wizard and complete the installation.
Note
The installer creates a service called Enterprise Recon 2 Agent that runs under the Local System user account.
For scanning MS SQL DB make sure to install the latest ODBC drivers package from the Microsoft site.
Uninstalling Agents from Windows

Make sure to install the latest ODBC drivers package from the Microsoft site. Windows agents uses the ODBC drivers installed on the agent host. ODBC Drivers version 17 required to support TLS 1.2 connections. ↩
Make sure that the agent can resolve its own hostname. If not, add it to its hosts file. ↩
Agents include a built-in PostgreSQL driver. This driver does not support password authentication with 'scram-sha-256' method. ↩↩↩
Agent includes built-in drivers. If the Agent host has SAP HANA ODBC drivers installed, the Agent will use those drivers instead of its built-in drivers. ↩
Agents include a built-in MySQL driver. This driver does not support password authentication with 'caching_sha2_password' method. ↩↩↩
Agent host architecture (32-bit or 64-bit) must match the Exchange Server. ↩
Running in Ubuntu 18. ↩
Requires installing some additional packages, included in the Installing Agents on Debian section. ↩
Requires installing some additional packages, included in the Installing Agents on RHEL section. ↩
Agents do not include drivers to connect to Teradata so they require Teradata Tools and Utilities. Install the Teradata Tools and Utilities 16.10.xx on the Agent host. Check Teradata instructions on how to complete the installation. You may need to restart the Agent host after installing Teradata Tools and Utilities. ↩
