SSO requirements

1. Identity Provider Integration
1.1. Integrate Auth0 as the centralized Identity Provider (IdP) for managing user authentication and authorization across all products and applications within the organization. Auth0 will be responsible for handling user identities, authentication, and authorization requests.
1.2. Support standard authentication protocols like OpenID Connect, OAuth 2.0, and SAML for seamless integration with external systems and applications. This will allow for federated identity management and enable single sign-on (SSO) across different platforms and services.
1.3. Enable federated identity management to facilitate authentication across different systems and identity sources. Users should be able to authenticate using their existing identities or other identity providers.

2. User Management
2.1. Maintain a centralized user directory in Auth0 for managing user identities, roles, permissions, and attributes. This directory will serve as the authoritative source for user information, ensuring consistency and avoiding data duplication across different systems.
2.2. Implement user provisioning and deprovisioning workflows, including synchronization with existing user data sources (e.g., Active Directory, LDAP, HR systems). This will ensure that user accounts are created, updated, and deactivated in a timely and consistent manner across all integrated systems.
2.3. Provide self-service capabilities for users to manage their profiles, update personal information, and reset passwords. This will empower users to take control of their accounts and reduce the administrative burden on the IT team.

3. Single Sign-On (SSO)
3.1. Implement SSO across all integrated products and applications using Auth0. Users should be able to authenticate once and gain access to all authorized applications without the need to re-enter their credentials.
3.2. Support SSO protocols like SAML, WS-Federation, and OpenID Connect. These industry-standard protocols will enable seamless integration with a wide range of applications and services.
3.3. Provide a centralized SSO portal or dashboard for users to access all applications with a single set of credentials. This portal should provide a unified experience for users, making it easy to discover and access authorized applications.

4. Multi-Factor Authentication (MFA) – Future Phase
4.1. Implement MFA capabilities using Auth0 to enhance security for user authentication. MFA will provide an additional layer of security by requiring users to present multiple forms of authentication (e.g., password, biometrics, one-time code).
4.2. Support various MFA factors like one-time passwords (OTP), push notifications, biometrics, and hardware tokens. Offering multiple MFA options will cater to different user preferences and security requirements.
4.3. Allow configurable MFA policies based on user roles, applications, risk profiles, or other criteria. This will enable organizations to tailor MFA requirements based on the sensitivity of the data or application being accessed.

5. Auditing, Logging, and Monitoring
5.1. Implement comprehensive auditing and logging mechanisms for authentication and authorization events. This will provide a detailed audit trail for security, compliance, and troubleshooting purposes.
5.2. Integrate with existing logging and monitoring systems for centralized log management and analysis. This will allow for aggregating and analyzing logs from various sources, enabling better visibility and insights.
5.3. Comply with relevant industry standards and regulations for logging and audit trails (e.g., GDPR, HIPAA, PCI-DSS). The auditing and logging capabilities should meet regulatory requirements for data protection and privacy.
5.4. Implement real-time monitoring and alerting for suspicious activities, failed login attempts, potential security threats, and performance degradations, with the ability to trigger automated response and remediation workflows. This will enable timely detection and response to security incidents, minimizing the potential impact of breaches or unauthorized access.

6. Scalability and High Availability
6.1. Ensure that the Auth0 implementation and SSO infrastructure are scalable to handle future growth in user base and application integrations. The solution should be able to accommodate increasing demand and workloads without compromising performance or availability.
6.2. Implement high availability and failover mechanisms to ensure uninterrupted service and minimize downtime. This will provide redundancy and ensure that the SSO solution remains accessible even in the event of hardware or software failures.
6.3. Leverage cloud-based infrastructure and auto-scaling capabilities to accommodate changing demand and load patterns. Cloud-based solutions offer inherent scalability and elasticity, allowing the SSO infrastructure to scale up or down based on usage patterns.

7. Migration and Integration
7.1. Develop a comprehensive migration plan to transition from existing authentication systems (e.g., Keycloak) to Auth0, ensuring data integrity and preserving user access. The migration process should be carefully planned and executed to minimize disruptions and maintain continuity of access for users.
7.2. Provide support for legacy systems that do not support SSO, implementing fallback mechanisms or integration adapters as needed. This will ensure that all applications and systems can be integrated with the SSO solution, regardless of their native support for SSO protocols.
7.3. Integrate Auth0 with existing products and applications, replacing their current authentication mechanisms. This will consolidate authentication and authorization under a single, centralized solution, simplifying management and improving security.

8. Single Sign-On (SSO) User Interface
8.1. Develop a dedicated SSO portal or dashboard that serves as a centralized access point for users to discover and launch authorized applications. The SSO portal should provide a user-friendly interface for accessing applications and services after successful authentication.
8.2. Ensure that the SSO portal is responsive and optimized for various devices and screen resolutions, including desktops, laptops, tablets, and smartphones. This will ensure a consistent and seamless user experience across different form factors.
8.3. Implement a modern and visually appealing design for the SSO portal, adhering to the organization's branding guidelines and providing a consistent look and feel across all integrated applications.
8.4. Allow for customization of the SSO portal's layout, color scheme, and branding elements to align with the organization's visual identity and preferences.
8.5. Display a personalized list of authorized applications and services for each user based on their roles, permissions, and attributes. This will ensure that users only see and access the applications they are entitled to use.
8.6. Provide search and filtering capabilities within the SSO portal to help users quickly find and access specific applications or services based on keywords, categories, or other relevant criteria.
8.7. Implement user-friendly navigation and application launching mechanisms, such as tiles, icons, or a search bar, to enable users to easily access and launch desired applications or services from the SSO portal.
8.8. Integrate with the organization's application catalog or service registry to dynamically populate the SSO portal with up-to-date information about available applications and services.
8.9. Implement accessibility features in the SSO portal, such as support for screen readers, high-contrast mode, and keyboard navigation, to ensure compliance with accessibility standards and accommodate users with disabilities.
8.10. Provide user self-service capabilities within the SSO portal, allowing users to update their personal information, manage their account settings, and reset their passwords without requiring administrative intervention.
8.11. Implement secure communication channels and encryption protocols to protect user data and ensure the confidentiality and integrity of information exchanged between the SSO portal and integrated applications.
8.12. Ensure that the SSO portal is compliant with relevant security standards and industry best practices, such as OWASP guidelines for web application security and NIST guidelines for authentication and access control.
8.13. Implement monitoring and logging mechanisms for the SSO portal to track user activities, identify potential security threats, and generate audit trails for compliance and troubleshooting purposes.
8.14. Provide comprehensive documentation and training resources for end-users, including user guides, video tutorials, and frequently asked questions (FAQs), to ensure a smooth adoption and effective utilization of the SSO portal.

9. Password Policy/Complexity
9.1. Establish minimum password length requirements, typically a minimum of 8-12 characters, to increase the complexity and entropy of user passwords.
9.2. Require a combination of character types, such as uppercase letters, lowercase letters, numbers, and special characters, to enhance password strength and reduce the risk of successful brute-force attacks.
9.3. Implement password complexity rules that prevent the use of common or easily guessable passwords, such as dictionary words, personal information (e.g., names, dates of birth), or sequential or repetitive patterns.
9.4. Enforce password expiration policies that require users to change their passwords periodically, typically every 90-0 days, to mitigate the risk of password compromise over time.
9.5. Implement password history rules that prevent users from reusing a certain number of previously used passwords, typically the last 5-10 passwords, to discourage password cycling and increase password diversity.
9.6. Provide clear and user-friendly error messages and guidance during password creation or reset to assist users in meeting the defined password policy requirements.
9.7. Allow users to set password hints or security questions to aid in password recovery processes while ensuring that the hints or questions themselves do not reveal sensitive information.
9.8. Provide self-service password reset capabilities that allow users to securely reset their passwords without requiring administrative intervention, while adhering to appropriate security controls and verification mechanisms (e.g., email or SMS verification, security questions).
9.9. Monitor and log password-related events, such as failed login attempts, password resets, and password policy violations, to facilitate auditing, incident response, and compliance reporting.

10. Privacy and Consent Management
10.1. Implement consent management mechanisms to allow users to review and control the sharing of their personal information with integrated applications or services, in compliance with data privacy regulations (e.g., GDPR, CCPA).
10.2. Provide clear and transparent privacy policies and notices to inform users about the data collected, processed, and shared during authentication and authorization processes.

11. Disaster Recovery and Business Continuity 
11.1. Develop and maintain a comprehensive disaster recovery and business continuity plan for the SSO solution to ensure service availability and data protection in the event of disasters or system failures.
11.2. Implement data backup and replication mechanisms to enable rapid recovery and minimize data loss in case of system outages or failures. 
11.3. Establish redundant infrastructure and failover mechanisms to ensure high availability and minimize downtime during disaster scenarios.

12. Session Management
12.1 Implement session policies to control and manage user sessions for enhanced security. This includes:
•	Idle Timeouts: Set a time limit for user inactivity after which the session will automatically expire. For example, if a user doesn't interact with the system for 30 minutes, their session ends, and they have to log in again. This prevents unauthorized access if a user walks away from their computer without logging out.
•	Maximum Session Durations: Limit how long a user can remain logged in continuously, even if they are actively using the system. For instance, a maximum of 8 hours forces users to periodically log out and log back in. This reduces the risk of sessions being hijacked or misused over extended periods.
•	Secure Session Revocation: Have a way to immediately terminate a user's session from the system in case of suspected unauthorized access or other security concerns. This could involve an admin remotely logging out the user or the system automatically revoking the session if it detects suspicious activity.
12.2 Implement notification systems to alert users before their session expires due to inactivity or maximum duration. For example, a pop-up 5 minutes before timeout reminds them to save work and stay active.
12.3 Allow users to manually terminate their own sessions when they are done using the system by providing a clear "Log Out" option.
