Your organization has had a data breach. You’ve managed to confirm that it’s not a false alarm, it really is an issue. And now you need to recover from it. What do you do? The US Commerce Department’s National Institute of Standards and Technology (NIST) has produced...
In today’s connected world and with security high on the agenda, IT people across the enterprise have to understand each other. Mainframers need to be able to talk to non-mainframers with clarity, and vice-versa. Managers in the enterprise need to understand both...
One way of looking at mainframe data is that it is either at rest or in transit. Data at rest is data that is not actively moving from device to device or network to network such as data stored on DASD or tape or some other way. Sometimes, data at rest is thought to...
In today’s treacherous world of constant hacking threats and corresponding data breaches, IT security and breach prevention has become a top-line concern for everyone in large IT organizations. With over six million data records lost or stolen every day – that’s...

In my last article I outlined why, for a number of reasons, mainframe shops are growing increasingly aware of the importance of bolstering security on their ‘Big Iron’ box. Despite that, in this piece I want to discuss why some organizations are procrastinating over...

To be honest, mainframes are pretty secure, aren’t they? We’ve had RACF and other External Security Managers (ESMs) for years. On top of that, the new z14 gives us pervasive encryption. And there are any number of logs recording what’s going on on Z, and we can run...
Mainframe files/datasets are liable to change quite often. After all, people are using those files so they are likely to be modified/updated. So how could you tell whether there had been a legitimate change to the file or it had been hacked? How can you verify that...
