IBM i 7.4 (V7R4) Details: Everything you need to know

IBM i 7.4 (V7R4) Details: Everything you need to know
IBM i V7R4 (7.4) OS400 enhancements and additions improve Power9 and Power8 system and DB2 database performance, security and availability. Details of OS400 V7R4 features and specifications for IBM i Power Systems are explained below in detail, and arranged by the following topics: Security, System Management, Networking, Availability, Application development, Miscellaneous features. IBM i V7R4 (7.1) release date is June 21, 2019. OS400 V7R4 is supported on IBM Power9 and Power8 processor systems, and is not supported on earlier IBM Power system processor generations. All IBM i customers should read the IBM 7.4 memo before upgrading to ensure compatibility and verify if discontinued support of any software, hardware products or features affects your system. IBM V7R4 hardware enhancement details can be read about here. IBM i SecurityIBM i Authority Collection A significant advancement for IBM i security is the new Authority Collection service feature, capable of analyzing object authorities of users and applications to ensure only the minimum required authorities are granted to run applications. By securing objects in an application with minimum authority required, security administrators can now safely remove unnecessary user authorities to objects used by an application. Most IBM i applications have excessive authorities granted to objects within the application. For instance, when an application gives *PUBLIC *CHANGE or *ALL authority for objects within an application, and accessing a DB2 file, when it only requires *USE authority to the data. Applications with unnecessary authorities creates security vulnerabilities by allowing users and other applications to make changes to data outside the application.   Authority Collection service captures data associated with the runtime authority checking built into IBM i security of OS400. The authority data collected is stored in a repository for displaying and analyzing the data and determine the minimum authority required to the objects the application need to run successfully. Minimum authority should be granted to objects as a best security practices require to protect against unauthorized access from outside the application.  IBM i 7.4 Authority Collection service also allows the collection of authority information for specific objects when accessed by any user, instead of for all objects accessed by a specific user....
