Set Up Firewall and DMZ

A firewall is one of the most common network devices used to secure a network environment. Set up a firewall and demilitarized zone (DMZ) to block unauthorized traffic. You should place the EnterpriseOne HTTP server in a DMZ configuration for internet facing systems. Keep the web application server, database, and Enterprise Server (otherwise known as the business logic or security server) behind a firewall. Firewalls provide assurance that access to these systems is restricted to a known network route that can be monitored.

In addition, you can also place a firewall between the Web Application Server and the database or Enterprise Server to add an additional layer of protection. See Additional Network Infrastructure Security for more information.

You should also install an Intrusion Detection System (IDS) and establish a policy to regularly monitor unauthorized traffic.
