Security requirements on IBM z/OS computers#
Specific security definitions are used to secure HCL™ Launch (UCD) functions for the IBM z/OS® environment. To deploy applications to an IBM z/OS environment, the user accounts on the agent computer must have adequate access permissions. You must also identify specific directories and data sets to the authorized program facility.
The topics in this section present the security configurations related to the agent started task, data sets, file systems, user IDs, impersonation and security configurations related to the z/OS Utility plugin.
Note: This document does NOT cover the UCD server’s security model and the security configurations related to server agent communication. Refer to UCD security configuration related to z/OS.
Agent started task and agent user ID#
The UrbanCode Deploy IBM z/OS agent is a long running Java process in the IBM z/OS UNIX System Services. The UrbanCode Deploy server distributes work, known as deploy processes, to an agent to execute. For each step in the deploy process, the agent starts a separate work process. The work process inherits the agent user ID’s security environment, unless the process is configured to use impersonation.
The su command is used to impersonate users. This figure shows a deployment scenario with two logical environments, DEV and TEST, in the same logical partition ( LPAR). The deployment process is configured so that the agent impersonates USERA when deploying to DEV and USERB when deploying to TEST.
- HardwareCryptography HCLJCECCAis not supported.
RACFdigital certificatesare not supported. UCD uses keystore and keytool provided by Java to generate and manage certifications to be used for the agent/server communication.
IBM z/OS agent user accounts
If you run the agent from a UNIX™ command line, the agent user account is the account that you use to log in to the UNIX shell. If you run the agent as a started task, the agent user account is assigned by the Resource Access Control Facility (RACF®) using the started procedures table (ICHRIN03) or the STARTED class. To learn more about RACF, see the z/OS Security Server RACF® System Programmer's Guide, SA23-2287-00.
- IBM z/OS authorized program facility
To deploy applications to an IBM z/OS environment, you must identify specific directories and data sets to the authorized program facility (APF).
- IBM z/OS directories and data sets
To deploy applications to an IBM z/OS environment, the user accounts on the agent computer must have adequate access permissions. You must also identify specific directories and data sets to the authorized program facility.
- IBM z/OS tokens
Tokens are used to authenticate with the HCL Launch server when z/OS component versions are imported.
- IBM z/OS component versions
Component versions forIBM z/OS are imported from the build LPAR by using the buztool.sh command.
- UCD security configuration related to z/OS
Information for the HCL Launch (UCD) server’s security model and the security configurations related to server agent communication for IBM z/OS are referenced in this topic.
