Encrypting the Communication

As a system administrator in charge of the security at your company, follow these steps to encrypt the communication between the components in an Automation Engine system.

If you are using old Agent versions with a more recent version of the Automation Engine, make sure that you deactivate the compatibility mode. For details see Deactivating the Compatibility Mode below.

Log in to Client 0.
Enter UC_AS_SETTINGS in the Global Search field.
A dropdown list with a link to the variable opens up. Click it to display the UC_AS_SETTINGS.
Activate the checkbox next to ENCRYPTION to activate it.
Click the file icon in the Value 1 column to open the Cell Editor, where you can enter the encryption strength.
Save your changes.

This encryption strength will be used for the following components:

Password storage within the CA Automic database repository
Database Password Reference within the Automation Engine Configuration File
Communication between the Automation Engines and the Agents
User interfaces
API Calls

Deactivating the Compatibility Mode

To be able to support Agents older than version 9.0, the Automation Engine supports unencrypted communication between components.

When the compatibility option is deactivated (COMPATIBILITY=NO in the UC_AS_SETTINGS system variable), the Job Messenger will only accept encrypted connections. The only exceptions are connections from the local IP address and the IP addresses that are defined as such in the Agent object. Set it to Y for Agents with a version older than 9.0.

The compatibility mode is deactivated as default for new installations.

Important! Use this configuration only if you are using old Agents. Otherwise, make sure that COMPATIBILITY is set to NO to guarantee a secure network communication.
