A role is a collection of permissions that define what actions a user can perform and what data they can access in the ServiceNow instance. Roles control access to applications, modules, tables, and specific functionalities throughout the system.
ServiceNow comes with many predefined roles such as admin (full system access), itil (IT service management tasks), catalog_admin (service catalog management), and knowledge (knowledge base management). Organizations can also create custom roles tailored to their specific business requirements.
Role Assignment is the process of granting roles to users or groups. There are several methods to assign roles in ServiceNow:
1. User Record Assignment: Roles can be assigned to individual users through their user record by adding entries to the Roles related list.
2. Group-Based Assignment: When users are added to groups that have roles assigned, they inherit those roles. This is the recommended approach for easier management and scalability.
3. Role Inheritance: Roles can contain other roles, creating a hierarchy. When a user receives a parent role, they automatically receive all child roles included within it.
Best practices for role management include following the principle of least privilege, where users receive only the minimum permissions necessary for their job functions. Organizations should regularly audit role assignments to ensure compliance and security.
The User Administration module provides tools for managing roles, including the ability to view role hierarchies, check who has specific roles, and understand role dependencies. Administrators can use the sys_user_has_role table to query and report on role assignments across the instance.
Effective role management ensures proper security, maintains data integrity, and supports compliance requirements while enabling users to perform their responsibilities efficiently within the ServiceNow platform.

Why Roles and Role Assignment Matter
Roles are fundamental to ServiceNow security and access control. They determine what users can see, do, and modify within the platform. Understanding roles is essential for the CSA exam because they affect nearly every aspect of system administration, from module visibility to record-level access.
What Are Roles?
A role is a collection of permissions that define what a user can access in ServiceNow. Roles control: - Access to applications and modules - Ability to read, write, create, or delete records - Access to specific UI elements and features - Script execution privileges
Roles are stored in the sys_user_role table and can be assigned to users or groups.
How Role Assignment Works
Roles can be assigned in several ways:
1. Assigning Roles to Users - Navigate to User Administration > Users - Select the user record - Use the Roles related list to add roles - The user receives all permissions associated with that role
2. Assigning Roles to Groups - Navigate to User Administration > Groups - Select the group record - Use the Roles related list to add roles - All group members inherit these roles
3. Role Inheritance - Roles can contain other roles - When a user has a parent role, they automatically receive all child roles - Example: The admin role contains many other roles
Key Role Types to Know
- admin: Full system access, can impersonate users - itil: Standard IT service management access for fulfiller users - snc_internal: Base role for all internal users - catalog_admin: Manage service catalog items - knowledge: Access to knowledge management features
Elevating Roles
Some sensitive roles require elevation, meaning users must explicitly activate them for a session. This adds an extra layer of security for powerful roles like security_admin.
Exam Tips: Answering Questions on Roles and Role Assignment
1. Remember the hierarchy: Roles assigned to groups are inherited by all group members. If a question asks how a user gets access, consider both individual and group role assignments.
2. Understand role inheritance: Know that roles can contain other roles. A user with a parent role gets all contained child roles.
3. Know the common roles: Be familiar with itil, admin, snc_internal, and catalog-related roles. Questions often reference these.
4. Group membership is key: When troubleshooting access issues in exam scenarios, check both the user's roles and their group memberships.
5. Elevated privileges concept: Remember that some roles require elevation and are not active by default even when assigned.
7. Access Control Lists (ACLs): Roles work with ACLs to control access. Questions may combine these concepts, so understand that roles are checked against ACL rules.
8. Process of elimination: For multiple choice questions, eliminate answers that suggest assigning roles through incorrect methods like modifying system properties or configuration files.
