Think Your Mainframe Is Secure? Think Again.

Understanding Mainframe Vulnerabilities

The mainframe is famous for being secure. However, even these robust systems are not immune to vulnerabilities and threats. Alarmingly, 91% of mainframe organizations have experienced a breach or compromise of data in the last five years. This statistic underscores the urgency for risk management and security leaders to prioritize mainframe security within their overall security strategy.

What are these vulnerabilities and threats? How can you identify them, and what steps can you take to ensure that you’re preventing them? Watch the full 30-minute webinar, Think Your Mainframe is Secure? Think Again, to address these risks head-on to protect your business.

Types of Mainframe Vulnerabilities

To effectively safeguard your mainframe, it's crucial to understand the types of vulnerabilities that can compromise its integrity:

Configuration-Based Vulnerabilities: These arise from improper settings and configurations, leaving the system open to unauthorized access.

Code-Based Vulnerabilities: These vulnerabilities stem from flaws in the code itself, which can be exploited by malicious actors.

Insider Threats: Employees or contractors with access to the mainframe can be a significant risk, whether through malicious intent or simple human error.

Low Use of Multifactor Authentication (MFA): Without MFA, systems are more susceptible to unauthorized access, significantly increasing the risk of data breaches.

Why Prioritizing Mainframe Security is Crucial 

Neglecting mainframe security can expose your business to millions of dollars in liabilities and losses. More importantly, it makes adherence to essential regulations like DORA (Digital Operational Resilience Act) and PCI 4.0 (Payment Card Industry Data Security Standard) challenging, if not impossible. These regulations require organizations to proactively mitigate vulnerabilities to enhance overall security posture.

To not only uncover the kinds of vulnerabilities and threats your mainframe is susceptible to but know where they are, how to look for them, and face them head-on, watch the full webinar today.

Implementing Effective Mainframe Security Measures 

To protect your enterprise effectively, consider the following steps:

Ensure You Have a Mainframe Security Architect: A dedicated security architect will help design and maintain a secure mainframe environment tailored to your organization's needs.

Implement Code-Based Vulnerability Scanning: Regularly scan your code for vulnerabilities to identify and address issues before they become significant threats.

Conduct Mainframe Penetration Tests Frequently: Regular penetration testing will help uncover potential security weaknesses and provide insights into how to bolster your defenses.

Implement Frequent Real-Time Compliance Checking: Continuously monitor for compliance with your organization’s policies to ensure you meet regulatory requirements and maintain a secure mainframe.

Full Implementation of Multifactor Authentication (MFA): Deploy MFA to add an extra layer of security, significantly reducing the risk of unauthorized access.


Mainframe security is not a one-time effort but an ongoing commitment. By understanding the types of vulnerabilities your mainframe faces and taking proactive steps to mitigate these risks, you can protect your enterprise from costly breaches and ensure compliance with industry regulations.
