To resolve the security
issues, you can configure a
firewall that restricts access to
ports configured for the cluster manager. You can configure the firewall to allow access to the ports only from
the machine that hosts the Informatica domain.
You can configure a
firewall of your choice to implement the access restrictions. Alternatively,
you can configure a firewall using IP rules. To
configure a firewall using IP rules, you can use firewalld, a Linux-based, firewall-management
You must make sure
that you enable SSL for the Informatica domain, the Catalog Service, and the
Informatica Cluster Service when you configure a firewall to restrict access.
