In an article authored by Al Saurette, CEO of MainTegrity, a discussion surrounding the vulnerability of mainframe security has been sparked. Despite the widespread reliance on mainframes by large organizations, the security of these systems often takes a backseat in conversations about cybersecurity. As the threat landscape continues to evolve and cyberattackers become increasingly sophisticated, the need to prioritize mainframe security has never been more urgent.
One of the primary challenges facing the security of mainframes is the impending retirement of a significant number of experienced security professionals. This, coupled with the existing skills shortage, places additional strain on remaining professionals tasked with addressing the growing complexity of security threats. Consequently, mainframe security often falls to the bottom of the priority list, leaving these critical systems vulnerable to potential attacks.
The misconceptions surrounding mainframe security also contribute to its neglect. Many believe that the mature architecture of mainframes makes them impervious to hackers, while others wrongly assume that they exist in isolation within the enterprise IT framework. Additionally, the lack of experience with mainframe systems among newer security professionals often leads to unquestioning acceptance of the viewpoints of their more seasoned counterparts.
This neglect of mainframe security is particularly concerning given the widespread use of modern mainframes for critical operations, such as processing e-commerce transactions and facilitating personal banking services. The potential implications of a breach are significant, with the average financial toll of a data breach estimated to be USD $9.48 million.
Addressing the threat to mainframes requires a focus on two key areas: encryption and early warning. Encryption, often considered a defense mechanism against cyberattacks, can also be exploited by malicious actors. It has become a favored attack vector due to its speed on modern mainframes and susceptibility to reversal. To proactively halt encryption before it causes substantial harm, a reliable method for detecting encryption in progress and initiating corrective measures is essential.
Similarly, achieving near real-time encryption monitoring is critical to mitigate the risk of malicious activities going undetected for prolonged periods. By identifying malicious encryption as soon as it starts and providing an instantaneous reaction, mainframe operators can significantly reduce the potential damage resulting from a breach.
To achieve this, a proactive approach that involves triggering real-time alerts when rogue processes are detected, updating whitelists of authorized encryption processes, and suspending offending processes, is necessary. By removing the reliance on human intervention, mainframe operators can effectively mitigate the risk of potential breaches.
Al Saurette, the CEO of MainTegrity, emphasizes the importance of embracing innovative new monitoring technologies and breaking out of a culture of complacency when it comes to mainframe security. As the landscape of cybersecurity continues to evolve, it is crucial for organizations to reevaluate their approaches to securing mainframe systems and prioritize the implementation of robust security measures.
With extensive experience in mainframes, hybrid cloud platforms, open systems, and mobile computing, Al Saurette is recognized as a thought leader in cybersecurity, compliance, and cyber resilience solutions. Through his leadership at MainTegrity, he aims to provide next-generation threat detection, advanced file integrity monitoring, automated forensics, and recovery solutions to address the pressing security challenges facing mainframe operators.
