What is Mainframe Penetration Testing?

A mainframe penetration testing is an assessment that identifies and fixes vulnerabilities within mainframe systems, using the same techniques as hackers to breach your infrastructure. 

According to most mainframe manufacturers, such as IBM, it is each user’s responsibility to identify and mitigate mainframe vulnerabilities, whether at the software or hardware level. Mainframe penetration testing allows organizations to uncover any opportunity for hackers to gain unauthorized access and provide actionable recommendations to mitigate each risk.

Mainframe systems are often viewed as being more secure than other types of systems because they are difficult to access and require specialized knowledge to work with. Mainframe penetration testing can help to identify these vulnerabilities so they can be addressed before an attacker has a chance to exploit them.


Top Mainframe Cybersecurity Risks

There are still risks associated with mainframe cybersecurity. One of the most common risks is privilege escalation. This occurs when an attacker gains access to a user account with more privileges than their own.

This can allow them to view or modify sensitive data, install malicious software, or even shut down the system entirely. Another risk is mainframe penetration, this is when an attacker gains access to the inner workings of the mainframe, potentially giving them control of the entire system. 

Our mainframe penetration testing methodology exploits your systems from various angles of attack in order to maximize the identified vulnerabilities. Although non-exhaustive, the following areas are generally the focal point of this type of assessment, as they cover the most common risks:
