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.

1. Download the DDC Agents ZIP file corresponding to the CipherTrust Manager version from the Thales Customer Support.

2. Check the Agent Compatibility Matrix to find a matching Agent to the desired Data Stores.

3. Extract the Agent Installer Package from DDC Agents ZIP and save it on the host machine where you want to install the Agent.

4. Follow the appropriate procedure for your Operating System.

   • RHEL Agents

   • Debian Agents

   • Windows Agents

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.

RHEL Agents

The table below lists all RedHat Linux Agent installer packages included in this release.

RHEL 5 is no longer supported. If you are running this Operating System, please consider upgrading.

Installing Agents on RHEL

To install the Linux 3 database runtime Node Agent on RHEL:

1. Install the epel-release package:

   sudo yum install epel-release
   

2. Install the required packages:

   sudo yum install libxml2 libgsasl openssl \
   libcurl libuuid protobuf krb5-libs libaio libnsl
   

3. Navigate to the location where the Agent installation package (.rpm) is stored.

4. 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 er2-2.9.0-linux3-rh-x64_database-runtime.rpm
   

5. 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.

6. 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.
   

   Tip

   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:

   127.0.0.1 localhost agent123

7. 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
     

Uninstalling Agents from RHEL

To uninstall a DDC Agent:

1. Stop the DDC Agent.

   sudo /etc/init.d/er2-agent stop
   

2. Remove the existing packages:

   sudo rpm -e er2
   

Debian Agents

The table below lists all Debian Linux Agent installer packages included in this release.

Debian 10 is no longer supported. If you are running this Operating System, please consider upgrading.

Installing Agents on Debian

1. Navigate to the location where the Agent installation (.deb) package is stored.

2. Install the required packages:

   sudo apt-get install libaio1 libaio-dev krb5-user \
   libgsasl7 libcurl4 libprotobuf10
   

3. Install the Agent by using the following command:

   sudo dpkg -i er2-2.x.xx-xxxx_xxxx.deb
   

   For example:

   sudo dpkg -i er2-2.9.0-linux3-x64_database-runtime.deb
   

   The package name that you use with the command may be different and depends on your system's architecture and Agent type.

4. Connect the Agent to the active CipherTrust Manager node:

   sudo er2-config -i <hostname|ip_address>
   

   where <hostname|ip_address> represents the IP address or hostname of the CipherTrust Manager node.

5. 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.
