CICS/SSO Modernization Guide

CICS/SSO provides secure single sign-on capabilities for CICS applications. It allows users to access multiple CICS applications with one set of credentials, improving user experience and reducing administrative overhead.

CICS/SSO is a tool that enhances the security and usability of CICS environments. It integrates with existing CICS infrastructure to provide a seamless single sign-on experience.

Organizations that rely heavily on CICS applications, particularly those with a large number of users and applications, benefit most from CICS/SSO. These organizations are often in industries such as banking, finance, insurance, and retail.

Consider CICS/SSO when you want to improve user productivity, reduce help desk calls related to password resets, and enhance the security of your CICS applications. It is particularly useful when dealing with regulatory compliance requirements.

Alternatives to CICS/SSO include manual password management, custom-built single sign-on solutions, and other third-party SSO products. However, CICS/SSO is specifically designed for CICS environments, offering tighter integration and better performance.

CICS/SSO requires a z/OS environment with CICS Transaction Server. It integrates with security managers such as RACF, ACF2, or Top Secret for user authentication and authorization.

Yes, CICS/SSO runs within an LPAR on z/OS. It leverages z/OS security features and integrates with CICS regions to provide single sign-on capabilities.

CICS/SSO typically integrates with existing security systems like RACF, ACF2, or Top Secret. It might also require configuration within CICS regions to enable single sign-on for specific applications.

CICS/SSO uses configuration files to define the single sign-on rules and integration with security managers. These files specify which users or groups have access to which CICS applications.

CICS/SSO improves user productivity by eliminating the need to enter credentials for each CICS application. It also reduces administrative overhead by simplifying user management and password resets.

By providing a centralized authentication mechanism, CICS/SSO helps organizations meet regulatory compliance requirements related to data access and security. It also provides audit trails for tracking user activity.

CICS/SSO reduces the risk of unauthorized access to CICS applications by enforcing strong authentication and authorization policies. It also simplifies security management by providing a single point of control for user access.

CICS/SSO supports authentication methods such as user ID and password, multi-factor authentication (MFA), and integration with external authentication providers via protocols like Kerberos or SAML.

CICS/SSO typically uses a role-based access control (RBAC) model, where users are assigned roles that determine their access privileges to CICS applications and resources. This simplifies access management and ensures that users only have access to the resources they need.

CICS/SSO uses encryption to protect sensitive data such as user credentials and session tokens. Encryption is typically used during transmission and storage to prevent unauthorized access.

CICS/SSO provides audit logging capabilities to track user authentication attempts, access to CICS applications, and other security-related events. These logs can be used for security monitoring, incident investigation, and compliance reporting.

CICS/SSO is typically deployed on-premise, within the organization's z/OS environment. It requires integration with existing CICS regions and security managers.

Implementing CICS/SSO requires technical expertise in z/OS, CICS, and security management. It involves configuring the product, integrating it with existing systems, and testing the single sign-on functionality.

Ongoing operational requirements include monitoring the performance and availability of CICS/SSO, managing user accounts and access privileges, and applying security patches and updates.

Common implementation challenges include integrating CICS/SSO with legacy applications, resolving compatibility issues, and ensuring that the single sign-on functionality works seamlessly across all CICS regions.
