  • Mainframe computers continue to play an essential role in a variety of public and private enterprises, including banking, health care, heavy machinery, and government sectors.
  • Many of the largest corporations in the world rely heavily on mainframe computers for their daily operations.

The mainframe occupies a coveted place in today’s e-business environment Even though other forms of computing are widely used in business to various degrees. Mainframe computers continue to play an essential role in a variety of public and private enterprises, including banking, health care, heavy machinery, and government sectors. Many of the largest corporations in the world rely heavily on mainframe computers for their daily operations. Over 68% of the world’s production IT workload still runs on the mainframe system.

IBM shared through the latest article that ‘Today, mainframe computers play a central role in the daily operations of most of the world’s largest corporations. While there are other forms of computing used extensively in business in various capacities, the mainframe occupies a coveted place in today’s e-business environment. In banking, finance, health care, government, etc. the mainframe computer continues to be the foundation of modern-day business.?

The performance of mainframes is unrivaled when it comes to processing high-speed transactions, handling large volumes of the transaction, and remaining cost-effective. The ability to handle multiple terabytes of data on mainframe systems provides an additional advantage over contemporary alternatives in terms of high-speed processing what it can do. In IT companies, the mainframe often hosts the most important applications such as order processing, inventory and production management, and payroll.

In spite of the fact that mainframe technology has evolved with time, it has developed concerns related to the possible ransomware that comes with it. The most common mainframe security threats include insider threats, code-based vulnerabilities, human error, hackers, and ransomware. This article showcases the mainframe ransomware concerns and protective measures used in any company.

Mainframe computers have kept up with the changing face of IT, with their ever-evolving ability to perform and process large numbers required by emerging technologies such as machine learning and artificial intelligence. It turns out that the mainframe is also vulnerable to ransomware, despite its reputation for security, reliability, and scalability. Mainframe is considered the most secure platform; But, it has its own flaws and weaknesses too. Hackers can easily attack mainframes through passwords. 72% of customer-facing apps are completely or very dependent on mainframe processing, according to Forrester. 57% of enterprises with mainframes run more than half of their business-critical apps on the mainframe. To circumvent the system’s lockout after five failed password attempts on a single user, a hacker usually tries a single password on every user on the system. A hacker could guess one or two passwords commonly used against all the accounts in a mainframe system that has hundreds of thousands of users.

Another most common method used by hackers is to interrupt the mainframe’s Customer Interaction Control System (CICS) Transaction Server. An attacker can build automated tools to enumerate as much of the CICS Transaction Server as possible to identify any misconfiguration that would allow them to bypass authentication.

In summary, the growing sophistication of hackers and the proliferation of opportunities for exploitation threatens the mainframe.

Is the mainframe susceptible to a ransomware attack? #

The mainframe is open to cybersecurity risks within its application and main operating system. As it becomes more distributed, hackers? techniques, tactics, and methods only become more sophisticated. From growing reliance on cloud services to IoT devices, there are now more network nodes than ever before. When it comes to application scanning, mainframe pros typically turn to popular scanning tools. These tools are not strong enough to mitigate code-based, OS-level vulnerabilities. can result in greater damage than attacks on applications alone. An OS vulnerability opens the door for more serious damage, allowing access to sensitive information and full control over an entire system. Hackers are capable of completely covering their tracks by removing common system logging or security controls, regardless of how well companies lock down the configuration side of the mainframe.

Ways to prevent mainframe attacks #

Due to its ability to handle large volumes of data and deliver microsecond response times, the mainframe continues to be a critical part of 71% of the Fortune 500 companies?

Proactive search for vulnerabilities**- Cybersecurity strategies should be in place from the very beginning and should offer strong solutions to prevent damage and establish defenses to prevent them from occurring in the first place. It is possible to prevent ransomware attacks by scanning regularly and automatically for vulnerabilities at every level of an company’s operating system. A continuous testing and evaluation program can reveal known vulnerabilities and zero-day flaws.

Whitelisting**- Most cyber security experts recommend whitelisting as the first line of defense against ransomware attacks. companies have started implementing application whitelisting which protects the mainframe from two types of security threats: malware and ransomware.

Adapting File Integrity Monitoring software**- The File Integrity Monitoring (FIM) system works by taking a snapshot of an application or configuration file and comparing it later with the current state of the application. An alert is sent in case the snapshots differ. By using the FIM tool, companies can perform scans and identify any modifications that have been made to the files. This helps in ensuring that the company is PCI compliant.

Patch management**- Patch management refers to the process of providing and applying updates to the software. Patches are frequently needed to address errors in the form of bugs and vulnerabilities that exist in the software. Patches are usually needed in operating systems, applications, and embedded systems (like networking equipment). A patch can be applied to fix a vulnerability that is discovered after the release of a piece of software. This ensures that assets in your environment are not exploitable.

Report ransomware attacks if they occur**- In the last few years, cyberattacks have become so common and destructive that new legislation has recently been introduced to require critical infrastructure companies to notify the federal government of cyberattacks and most companies to inform the government if they are being victims of ransomware attacks. These attacks have become more prevalent, increasing the necessity of safeguarding the mainframe.

Conclusion #

The risk of security breaches increases with the rise in complexity and interconnection of the IT system of an company. So, it is essential that every company must be aware of the importance of mainframe security and prepare to execute on it, especially where sensitive customer data is involved.
