You can enable different options to secure specific components in the domain. You do not have to secure all components in the domain. For example, you can secure the communication between the services in the domain but not secure the connection between the Model Repository Service and the repository database.

Informatica uses the TCP/IP and HTTP protocols to communicate between components in the domain. The domain uses SSL certificates to secure communication between components.

When you install the Informatica services, you can enable secure communication for the services in the domain and for the Administrator tool. After installation, you can configure secure communication in the domain in the Administrator tool or from the command line.

During installation, the installer generates an encryption key to encrypt sensitive data, such as passwords, that are stored in the domain. You can provide the keyword that the installer uses to generate the encryption key. After installation, you can change the encryption key for sensitive data. You must upgrade the content of repositories to update the encrypted data.

You can enable secure communication in the following areas:
