Configuring Role-Based Access Control on Panorama (Version 11.0)

PCNSE Objective Focus

This topic directly addresses PCNSE objectives related to securing administrative access to Panorama using Role-Based Access Control (RBAC).

Identify methods for configuring administrative access to Panorama.
Configure custom Admin Roles and Access Domains.
Assign roles and domains to Panorama administrators.
Understand the principle of least privilege in Panorama administration.

Overview: Securing Panorama Administration

Panorama provides powerful centralized management, making it critical to control who can access it and what actions they can perform. Role-Based Access Control (RBAC) on Panorama enables administrators to enforce the principle of least privilege, ensuring users only have the permissions necessary to perform their job functions.

RBAC separates administrative privileges into two key components:

What users can DO: Defined by Admin Roles , which specify access rights to different GUI tabs, CLI commands, and XML API functions.
What users can SEE/MANAGE: Defined by Access Domains , which limit the scope of a user's visibility and control to specific Device Groups, Templates, managed firewalls, or shared objects.

By combining Admin Roles and Access Domains, you can create highly granular permission sets for different administrative users or groups.

Key RBAC Components

Admin Roles

Define functional access privileges (permissions).
Determine which parts of the Panorama GUI, CLI, and API an administrator can use.
Panorama includes several predefined roles (e.g., Superuser, Panorama Admin, Device Admin, Read Only).
You can create custom roles for more granular control, enabling/disabling access to specific tabs, sub-tabs, actions (e.g., commit, push), and command-line elements.
Location: Panorama > Admin Roles

Access Domains

Define the scope of configuration and visibility (data access).
Limit which Device Groups, Templates, specific managed devices (firewalls/collectors), virtual systems (on firewalls), and shared objects an administrator can view and modify.
The `All` access domain provides visibility into everything (typically reserved for superusers).
You create custom access domains to restrict scope (e.g., an access domain for only the 'Retail-Stores' Device Group and Template, or an access domain for 'North-America-Firewalls').
Location: Panorama > Access Domains

Administrators

User accounts defined on Panorama for administrative access.
Can be local accounts or based on external authentication (RADIUS, TACACS+, LDAP, SAML via Authentication Profiles/Sequences).
Each administrator account is assigned:
- An Admin Role (predefined or custom) determining their *privileges*.
- An Access Domain (predefined 'All' or custom) determining their *scope*.
Location: Panorama > Administrators

Configuring Custom Admin Roles (11.0)

While predefined roles exist, custom roles offer tailored permissions.

Navigate to Panorama > Admin Roles .
Click Add .
Enter a descriptive Name for the role (e.g., `Firewall-Operator`, `Security-Policy-Auditor`).
Configure access privileges across different sections:
- Web UI: Check/uncheck specific tabs and sub-tabs (e.g., allow Monitor tab but disable Policies tab). You can often control specific actions within tabs (e.g., allow viewing rules but disable creating/editing).
- Command Line: Enable/disable specific CLI command trees or individual commands.
- XML API: Control access to different API endpoints (e.g., allow operational requests but block configuration requests).
- Other Permissions: May include options for specific actions like Commit, Push, software/content management.
Click OK to save the custom role.
Commit the changes on Panorama.

Start with minimal privileges and add permissions as needed, following the least privilege principle.

Configuring Access Domains (11.0)

Access Domains restrict the devices and configuration objects an administrator can manage.

Navigate to Panorama > Access Domains .
Click Add .
Enter a descriptive Name for the domain (e.g., `EMEA_Region_Devices`, `PCI_Segment_Policy`).
Select the specific items to include in this domain's scope:
- Device Groups: Select the DGs the user should manage.
- Templates / Template Stacks: Select the Templates/Stacks the user should manage.
- Managed Devices: Optionally, select specific individual firewalls or collectors.
- Virtual Systems: Select specific Vsys if applicable.
- Shared Objects: Control access to Shared objects (Global level).
- (Advanced) You might also control access to specific reporting contexts.
Click OK to save the access domain.
Commit the changes on Panorama.

Carefully plan your Access Domains. An administrator assigned to a specific domain will ONLY see and be able to manage the items explicitly included in that domain.

Creating Administrator Accounts (11.0)

Combine Roles and Domains when creating administrator accounts.

Navigate to Panorama > Administrators .
Click Add .
Enter a Name (username) for the administrator.
Choose the Authentication Profile :
- `None` (for local password authentication).
- Select a pre-configured profile for RADIUS, TACACS+, LDAP, or SAML.
If using local authentication, set and confirm the Password . Configure password complexity requirements under Panorama > Setup > Management > Authentication Settings .
Select the Administrator Type :
- Role Based: This is the standard option using RBAC.
  - Select the desired Role (predefined or custom) from the dropdown.
  - Select the desired Access Domain (predefined 'All' or custom) from the dropdown.
- Dynamic: Used with external authentication (RADIUS/TACACS+) where roles/domains can be passed back via Vendor-Specific Attributes (VSAs).
- (Older/Legacy) `Superuser` or `Device Administrator` types exist but Role Based is preferred for flexibility.
Click OK to save the administrator account.
Commit the changes on Panorama.

Example Scenarios

Scenario 1: Regional Firewall Operator
- Admin Role: `Firewall-Operator` (Custom role allowing Monitor tab, basic troubleshooting commands, view Policies/Objects, but NO commit/push or changes to Panorama settings).
- Access Domain: `EMEA_Region_Devices` (Custom domain including only Device Groups and Templates related to the EMEA region).
- Result: User can monitor and perform basic troubleshooting on EMEA firewalls only, cannot make configuration changes or see other regions.
Scenario 2: Security Policy Auditor
- Admin Role: `Auditor-Role` (Custom role allowing read-only access to Policies, Objects, Monitor tabs, and related CLI commands).
- Access Domain: `All` (Predefined domain allowing visibility across all DGs/Templates).
- Result: User can view all policies and logs across the entire managed infrastructure but cannot make any changes.
Scenario 3: Network Team Template Manager
- Admin Role: `Network-Template-Admin` (Custom role allowing full access to the Templates tab, relevant Network CLI commands, Commit, and Push, but limited access to Policies tab).
- Access Domain: `All` (Access to all Templates needed, but role restricts policy modification).
- Result: User can manage network configurations (interfaces, routing via Templates) for all devices but has restricted access to security policy rules.

Best Practices for RBAC

Principle of Least Privilege: Grant only the minimum permissions (Role) and scope (Domain) necessary for a user's tasks.
Use Custom Roles: Avoid using broad predefined roles like 'Panorama Admin' or 'Device Admin' if possible. Create specific custom roles.
Use Custom Access Domains: Segment administrative scope logically (by region, function, security zone, etc.) using custom domains. Avoid using the 'All' domain except for top-level administrators.
Leverage External Authentication: Integrate with RADIUS, TACACS+, LDAP, or SAML for centralized user management and authentication policies (MFA, password complexity).
Use Dynamic Roles (Optional): If using RADIUS/TACACS+, consider using VSAs to assign roles/domains dynamically based on group membership in the external directory.
Regular Audits: Periodically review administrator accounts, roles, and domains to ensure they are still appropriate and remove unused accounts. Check Panorama's Config Audit logs.
Separate Duties: Use RBAC to enforce separation of duties (e.g., one team manages network settings via Templates, another manages security policies via Device Groups).
Test Roles Thoroughly: Before assigning a new custom role, test it extensively to ensure it grants the correct access and doesn't inadvertently block necessary functions or grant excessive privileges.

Caveats / Gotchas / Considerations

Complexity: Highly granular RBAC can become complex to manage. Keep roles and domains as simple as possible while meeting security requirements.
Misconfiguration Risk: Incorrectly configured roles or domains can either lock users out of necessary functions or grant unintended broad access. Test carefully.
Troubleshooting Permissions: Diagnosing why a user can't perform an action can be tricky. It requires checking both their assigned Role *and* their Access Domain scope.
Shared Objects Access: Access to 'Shared' objects (in the Objects tab) is controlled within the Access Domain configuration. Users might need access to specific shared objects even if managing restricted DGs/Templates.
Commit/Push Permissions: The ability to Commit (locally on Panorama) and Push (to devices) are powerful permissions controlled within the Admin Role. Grant these cautiously.
API Access: Remember that Admin Roles also control XML/REST API access. Ensure roles assigned to service accounts used for automation have appropriate API permissions.
Changes Require Commit: All changes to Administrators, Admin Roles, and Access Domains require a Commit on Panorama to take effect.
