The Omnissa WS1 UEM API must be configured to use approved authorizations for access control.

To mitigate the risk of unauthorized access to sensitive information by entities that have been issued certificates by DoW-approved Public Key Infrastructures (PKIs), all DoW systems (e.g., networks, web servers, and web portals) must be properly configured to incorporate access control methods that do not rely solely on the possession of a certificate for access. Successful authentication must not automatically give an entity access to an asset or security boundary. Authorization procedures and controls must be implemented to ensure each authenticated entity also has a validated and current authorization. Authorization is the process of determining whether an entity, once authenticated, is permitted to access a specific asset. Information systems use access control policies and enforcement mechanisms to implement this requirement. Access control policies include identity-based policies, role-based policies, and attribute-based policies. Access enforcement mechanisms include access control lists, access control matrices, and cryptography. These policies and mechanisms must be employed to control access between users (or processes acting on behalf of users) and objects (e.g., devices, files, records, processes, programs, and domains) in the information system. This requirement is applicable to access control enforcement applications (e.g., authentication servers) and other applications that perform information and system access control functions. Methods include: - Basic Authentication (not recommended). - API Key Authentication. - TLS Encryption. - OAuth 2.0. - JWT-Based Authentication. - OpenID Connect (OIDC).

Verify WS1 UEM REST API access control has been configured to require "Directory" authentication. 1. Log in to the WS1 UEM console. 2. Navigate to Groups & Settings >> All Settings >> System >> Advanced >> API >> REST API >> Authentication tab. 3. Verify the authentication configuration is set correctly: Basic - "Disabled", Certificates - "Disabled", and Directory - "Enabled". 4. Verify the Child Permission is set to "Inherit only". If the WS1 UEM REST API authentication is not set correctly, this is a finding.

Implement WS1 UEM REST API access control has been configured to require "Directory" authentication using the following procedures: 1. Log in to the WS1 UEM console. 2. Navigate to Groups & Settings >> All Settings >> System >> Advanced >> API >> REST API >> Authentication tab. 3. If the configuration is already set as listed in step 4 below, select "Inherent". If the configuration is not already set as listed in step 4 below, select "Override". 4. Select the following settings: Basic - "Disabled", Certificates - "Disabled", and Directory - "Enabled". 5. For Child Permission, select "Inherit only".
