Description
To mitigate the risk of unauthorized access to sensitive information by entities that have been issued certificates by DOD-approved PKIs, all DOD 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 by the application 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. The Okta Global Session Policy is applied at the organization level and before any application-specific authentication policies are processed. The Okta authorization package should contain an access control policy that defines IP ranges from which to either allow or deny access. This list (either as an explicit allow or explicit deny) can be implemented in the Global Session Policy.

ℹ️ Check
From the Admin Console: 1. Select the "Security" menu, and then click the "Global Session Policy" item. 2. In the "Policy Settings" section, verify the "IF User's IP is" setting is correctly set to either allow or deny based on the organization defined policy. If the Okta Global Session Policy is not configured to restrict access to specific IP ranges, this is a finding.

✔️ Fix
From the Admin Console: 1. Select the "Security" menu, and then click the "Global Session Policy" item. 2. In the Policy Settings section, configure the "IF User's IP is" setting to correctly set the appropriate network to either allow or deny based on the Access Control Policy.
