Comparison of Automated Sign-On Options for Mainframe

This whitepaper presents a detailed comparison of automated sign-on options for mainframe applications, addressing the challenges associated with traditional password management. It outlines the need for improved security measures as many mainframe applications still rely on outdated password protocols. The document discusses various solutions, including Enterprise Single Sign-On (ESSO) and the Express Logon Feature (ELF), explaining how each solution operates and its implications for security and usability. ESSO allows users to authenticate once and access multiple resources without re-entering credentials, while ELF utilizes X.509 certificates for secure logon without the need for static passwords. The paper also highlights considerations for implementation, such as the complexity of integrating these solutions into existing infrastructures and the potential costs involved. By providing selection guidelines, the whitepaper aims to assist organizations in choosing the most suitable automated sign-on solution for their mainframe security needs.
