What is a mainframe security engineer?

Mainframe Security Engineers are IT professionals responsible for ensuring the security of mainframe computer systems, which are powerful servers used by large organizations for critical applications. They design, implement, and manage security measures to protect data, applications, and infrastructure on mainframe platforms. This includes configuring access controls, monitoring for security breaches, conducting risk assessments, and staying updated on security vulnerabilities and compliance requirements. Mainframe Security Engineers often work with tools like RACF, ACF2, or Top Secret to manage permissions and audit usage. Their expertise helps organizations prevent unauthorized access and maintain the integrity and confidentiality of their most sensitive data.
