It’s Time to End the Myth of Untouchable Mainframe Security. By Al Saurette, CEO, MainTegrity, Most large organizations, including 70% of Fortune 500 companies, rely extensively on mainframes for managing their business and IT infrastructure. However, despite the significant role mainframes play, the conversation of how to best secure mainframes security does gets relatively little attention. Considering today’s cyberthreat landscape mainframes have never been more vulnerable to attacks. Cyberattackers are becoming bolder, stronger and more innovative by the day. The timing couldn’t be worse. A large cohort of senior, experienced security professionals are set to retire in the coming years, further exacerbating the ongoing skills shortage and exerting more pressure on remaining professionals. As the complexity of threats increases, their jobs become tougher. Short-staffed security teams will tend to prioritize their time and mobilize their efforts to reactively address the most obvious issues, which often means mainframe security falls to the bottom of the priority list. It is critical for mainframe security to re-enter the cybersecurity conversation, and that starts with doing away with commonly held misconceptions. First is the mistaken belief that due to their mature or Cyber Defense eMagazine – January 2024 Edition 112 Copyright © 2024, Cyber Defense Magazine. All rights reserved worldwide.
streamlined architecture with fewer vulnerabilities, mainframes are virtually impervious to hackers. There is the misconception that they exist in isolation within the enterprise IT framework, disconnected from the external world where genuine threats lurk. And then there’s the age factor. People newer to the profession have relatively little experience with mainframe systems when compared to their more experienced counterparts and will tend to not question their viewpoints or approaches of their leaders or senior team members. This state of affairs can’t continue. In the contemporary landscape, modern mainframes are routinely accessed by employees and are intricately linked to applications that encompass a wide array of functions, ranging from processing e-commerce transactions to facilitating personal banking services. The implications of a breach can’t be overstated. Given the substantial financial toll of a data breach, estimated to be USD $9.48 million on average, it’s imperative to swiftly detect any potential threat to the mainframe. To counter this threat to mainframes, security teams must look at two key areas: encryption and early warning. Encryption is now a weapon, and must be treated accordingly Encryption is a double-edged sword in today’s IT environment. On one hand it serves as a crucial defense mechanism against cyberattacks targeting sensitive data. On the other, encryption can be manipulated by unscrupulous individuals, disgruntled employees, or even rogue state actors. It has emerged as a favored attack vector among hackers due to its remarkable speed on modern mainframes and its susceptibility to reversal. Consequently, malicious actors often follow a straightforward modus operandi: infiltrate a system, initiate malicious encryption, and then attempt to sell the decryption key back to the victim. It is paramount to proactively halt encryption before it causes substantial harm. The primary challenge lies in establishing a reliable method for detecting encryption in progress, while preventing the support staff from being overwhelmed with an avalanche of alerts. This is especially important in large business and government settings, where the routine exchange of encrypted files is common. A glut of alerts can lead to a desensitized response, ultimately leaving the system no more secure than it was. To address this, an immediate response, ideally within seconds, is imperative. Unfortunately, relying solely on human intervention falls short of achieving the required speed. The solution lies in the deployment of a specialized tool capable of swiftly detecting the initiation of encryption and promptly initiating corrective measures. Achieving near real-time encryption monitoring IBM Security's 2023 Cost of a Data Breach Report highlights a troubling reality: it takes an average of 204 days to detect a breach, followed by an additional 73 days to recover.
