As of 2023, over 72% of businesses worldwide have been affected by ransomware attacks. With new attacks seemingly every day and the cost of these attacks on the rise, companies know they can’t afford to joke around about security. Because of this, many are opting to...
You could argue – as some folks have – that mainframes are inherently more secure than commodity servers because there are fewer variables at play on mainframe systems, making them easier to secure in some ways. The fact that mainframes account for a relatively small...
In the Db2 for z/OS module called DSNZPARM (ZPARM, for short), which provides the configuration settings for a Db2 subsystem, there is a parameter named SEPARATE_SECURITY. This ZPARM was introduced with Db2 10, and its purpose is to enable a Db2 for z/OS-using...
Quantum Safe Cryptography The Problem – Current Cryptography is Vulnerable to Quantum Computing Cryptography experts believe that by 2030 quantum computers will be advanced enough to cut the strength of symmetric key algorithms (such as AES, 3DES and RC4) by half, and...
My mac had turned into a bit of a mess. I had ssh private keys (that use Passphrases of course!) in a variety of places and I wasn’t very happy about it. I have several different servers that I connect to. There are a few GitHub systems, a Linux system, and of course...
Resiliency is an integral part of the IBM Z platform. The IBM Z Cyber Vault solution is a concept for addressing data corruption whether through malicious intent, human error or failure of hardware or software. It provides an air gapped backup of the operating...
