Security Enhancements in z/VSE V4.1


Security in z/VSE is provided by the Basic Security Manager (BSM), which is part of z/VSE central functions and provides basic functionality. Clients with more demanding security needs (e.g., field-level security, command security) may choose to use a security manager product from an Independent Software Vendor (ISV) instead of BSM.

As applications of the ’70s and ’80s become obsolete, more IT shops have queued application modernization projects. These are complex, costly, and risky; however, some degree of automation in the transformation process still appears attractive. Looking only at the costs, rewriting the application from scratch in a new environment, without any automation, would roughly entail at least the same effort and costs as the original. The costs are prohibitive and the extended development time may render the new incarnation of the application obsolete even before it’s used in production. Automation is one way to solve these difficulties. …

In previous articles, we examined virtualization from the standpoint of an entire machine, running an unmodified guest operating system. This time, we’ll explore virtualization options that don’t necessarily virtualize the entire machine. Rather, we’ll begin considering applications as increasingly more abstract collections of resources, and we’ll begin to look at how you  can re-factor your workload into logical components and concentrate on consolidating and virtualizing those, rather than physical components of your computing infrastructure.

Automation of Processes in VSE

VSE provides many different methods of process automation; some of them have been around for decades in the traditional mainframe world and involve JCL, timeevent scheduling, VM, rEXX, and various OEM products. In contrast to that, new functionality is provided in the open world and can be used in a VSE environment with surprisingly little effort. One example is the open source software project, Ant, which provides a Java-based build tool. On the basis of the VSE Java-based connector, Ant scripts can be used to submit jobs, enter operator console commands, and upload and download files.

Compliance Options: Embedded Compliance

Has this ever happened to you?  You have a job to do, so you make a plan and then execute it. The work is done, you’ve checked it twice, and you’ve completed all your follow-on documentation and reporting. You breathe a big sigh of relief. Except—out of the blue—someone tells you there’s another thread of activities to be done.  You have to start over, from the beginning ……

Understanding the Fundamentals of FTP

File Transfer Protocol (FTP) is a widely accepted standard on almost all platforms that have implemented TCP/IP. It’s used to transfer files between two systems. RFC 959 is the definitive Internet Engineering Task Force (IETF) document that defines the FTP protocol, and it also contains an excellent overview, history, and detailed explanation of the FTP protocol. The objectives of FTP, according to RFC 959, are to:…
