z/OS & Mainframe
z/OS is the high-performance operating system for IBM mainframes, primarily used in enterprises for business-critical applications. Since mainframes often process large amounts of sensitive data (from financial transactions to government information), their security is essential. Especially in the context of the Digital Operational Resilience Act (DORA), the security of mainframe platforms usually plays a fundamental role.
Very specific knowledge is required for pentesting z/OS and mainframes. Therefore, we work with our partner Dr. Stephen Fedtke, whom we introduce on our Collaboration page.
Why Pentest z/OS and Mainframe?
Our key reasons for pentesting z/OS and mainframes:
- Uncovering privilege escalation paths that compromise data confidentiality, integrity, and availability
- Identifying vulnerabilities in system configuration
- Compliance with regulatory requirements, such as DORA
When to Pentest z/OS and Mainframe
In our view, the best times are:
- Ideally before productive use – if not already done, as soon as possible
- When components are modified and new features are added
- Regularly, to test vulnerabilities against new attack methods
Results
- Insights into privilege escalation paths, for example, through weaknesses in central security functions like RACF, Top-Secret, and ACF2, and user ID takeover
- Identifying configurational vulnerabilities
