The most robust computing platform now in use is mainframes. However, it doesn’t follow that you can’t take further measures to provide your mainframe with even more security.

What features of your mainframe security are inherent, and what can you do to raise those features? Get an overview of mainframe security benefits and advice on enhancing mainframe security.

Why Are Mainframes Inherently Secure?

Because of the lack of vulnerable endpoints in their streamlined architecture, mainframes are secure. Technologies that have demonstrated their capacity to safeguard endpoints are used to protect customer information.

Compared to alternative infrastructure types, such as the cloud or on-premises commodity servers, mainframes have inherent advantages in terms of security.

The biggest of these benefits is that mainframes tend to receive far less attention from hackers than other types of systems that are thought of as more current since they are not the first form of computing infrastructure that most people think of.

It’s controversial whether it is a fair judgment given that mainframes process a good amount of highly important data, such as credit card transaction data.

However, mainframes are smaller targets for those who are up to no good because they have a lower public profile than the cloud or commodity servers.

Mainframe Security Best Practices

Businesses that rely on mainframes for mission-critical workloads must modernize their security strategies to counter threats. Here is a list of some of the mainframe security best practices your company can use to protect its mainframe. There are many reasons why large businesses rely on mainframes, such as their reliability, security, scalability, and compatibility.

Reliability

The importance of a system remaining operational always is significant. RAS (reliability, availability, and serviceability) refers to a group of features of hardware and software that mainframe users find valuable.

Mainframe operating systems display RAS through features like storage protection and a controlled maintenance procedure, in addition to the hardware’s solid self-recovery abilities. The software’s reliability results from thorough testing and the ability to release patches quickly when problems are found. Hardware and software components can be changed without adversely affecting the rest of the operating system.

Security

A vital company resource is security data. Essential data must be securely kept, including customer lists, employee profiles, and financial records. The data must also be accessible to users who can view it. A mainframe computer can manage both. It is feasible to share while maintaining data security.

Scalability

Businesses frequently expand, demanding new infrastructure to meet rising demand. The scalability of the computer platform is a significant element in determining how much a corporation can expand its capacity without significantly increasing costs or disturbing current operations. Scalability of hardware and software is a feature of mainframes.

Compatibility

Usually, mainframe clients have made significant investments in their data and applications. Others might be brand-new, while some applications have taken years to perfect. “Compatibility” refers to a program’s ability to run on a system or interact with other hardware or software.

Maintaining support for all applications, regardless of age, is critical. The requirement for compatibility is a significant design factor in both new software and system hardware. Although it is impossible to maintain complete compatibility over decades of changes, mainframe hardware and software manufacturers prioritize it.

Staying Power

It is not unexpected that the mainframe has continued to flourish and be popular even in the age of cloud computing. The commercial world of today involves several transactions. Vast volumes of transactional data are produced via sensor collection, high-frequency trading, the industrial internet of things (IIoT), and the internet of things (IoT). This information must be digested and used at incredible speeds to keep production lines operating and end-user apps responding.

Thanks to its greater processing power, the mainframe has the most powerful computing capability, designed to process up to 1 trillion web transactions daily.

Consumer behaviors are also evolving, and thanks to mobile devices, people are checking their bank balances far more frequently than they used to. Each of those lookups represents a successful transaction. The same holds for pre-loading shopping carts, mobile payments, and informal communications.

The increase in transaction volume reaching the backend led to the development of mainframes. They can operate at speed and scale far exceeding those of many systems meant to replace the technology.

Conclusion

So, to maintain mainframe security, the mainframe mentioned above security best practices should be considered. The popularity of mainframes is due mainly to their high level of dependability and security. They have continued to develop and improve while maintaining compatibility with earlier iterations. IT companies frequently host critical programs on the mainframe. These applications cover various topics, such as payroll, client order processing, inventory and production control, financial transactions.
