| V-284174 | medium | 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).

| V-284197 | medium | The Omnissa WS1 UEM API must employ throttling. | The API must employ throttling to limit the effects of information flooding types of denial-of-service (DoS) attacks. DoS is a condition when a resource is not available for legitimate users. When this occurs, the organization either cannot accomplish its mission or must operate at degraded capacity.
In the case of application DoS attacks, care must be taken when designing the application to ensure the application makes the best use of system resources. SQL queries have the potential to consume large amounts of CPU cycles if they are not tuned for optimal performance. Web services containing complex calculations requiring large amounts of time to complete can bog down if too many requests for the service are encountered within a short period of time.
The methods employed to meet this requirement will vary depending upon the technology the application uses. However, a variety of technologies exist to limit or, in some cases, eliminate the effects of application-related DoS attacks. Employing increased capacity and bandwidth combined with specialized application layer protection devices and service redundancy may reduce the susceptibility to some DoS attacks. |
