Check the security for ports 32207 and 32208

Description

With the removal of IBM® WebSphere® Application Server OEM Edition for z/OS® in z/OSMF V2R1, the specification of HTTP port values is changed. You can use the z/OSMF supplied port settings, or specify new values during the z/OSMF configuration process.

The port values are specified through the following configuration variables:
  • IZU_HTTP_SSL_PORT, which specifies the port number for SSL encrypted traffic from your z/OSMF configuration. As of z/OSMF V2R1, the default port number is changed from 32208 (the WebSphere default), to 443, which follows the Internet Engineering Task Force (IETF) standard.
  • IZU_HTTP_PORT, which was added in z/OSMF V2R1. This variable specifies the port number for non-encrypted traffic, which is 80, by default. Note that if your installation is migrating from an earlier release of z/OSMF, however, you might have specified port number 32207 for this value, which is the WebSphere default.

Table 1 provides more details about this migration action. Use this information to plan your changes to the system.

Table 1. Information about this migration action
Element or feature: z/OSMF
When change was introduced: z/OS V2R1.
Applies to migration from: z/OS V1R13.
Timing: Before installing z/OS V2R2.
Is the migration action required? Yes, if you want to use the current defaults.
Target system hardware requirements: None.
Target system software requirements: None.

Steps to take

If your installation is migrating from an earlier release of z/OSMF, you might have used port numbers 32207 and 32208 forz/OSMF web traffic. These earlier values are not persisted when you migrate to z/OS V2R2. Determine whether ports 32207 and 32208 should remain active on your system, and update the settings or close the ports, as required by your installation security policies.
