The Sentry providing intermediary services for remote access communications traffic must use encryption services that implement NIST FIPS-validated cryptography to protect the confidentiality of remote access sessions.

Description
Without confidentiality protection mechanisms, unauthorized individuals may gain access to sensitive information via a remote access session. Remote access is access to DoD nonpublic information systems by an authorized user (or an information system) communicating through an external, non-organization-controlled network. Remote access methods include broadband and wireless connections. Remote access methods include, for example, proxied remote encrypted traffic (e.g., TLS gateways, web content filters, and webmail proxies). Encryption provides a means to secure the remote connection so as to prevent unauthorized access to the data traversing the remote access connection, thereby providing a degree of confidentiality. The encryption strength of the mechanism is selected based on the security categorization of the information. This requirement applies to ALGs providing remote access proxy services as part of its intermediary services (e.g., OWA or TLS gateway).

Check Text ( C-54446r802253_chk )
Verify the Sentry uses encryption services that implement NIST FIPS-validated cryptography to protect the confidentiality of remote access sessions. On the MobileIron Sentry CLI console, do the following: 1. SSH to MobileIron Sentry Server from any SSH client. 2. Enter the administrator credentials established when MobileIron Sentry was installed. 3. Enter "enable". 4. When prompted, enter the "enable secret" set when MobileIron Sentry was installed. 5. Enter "show FIPS". 6. Verify "FIPS 140 mode is enabled" is displayed. If the MobileIron Sentry Server does not report that FIPS mode is "enabled", this is a finding.

Fix Text (F-54400r802254_fix)
Configure the MobileIron Sentry server to use a FIPS 140-2-validated cryptographic module. On the MobileIron Sentry console, do the following: 1. SSH to MobileIron Sentry Server from any SSH client. 2. Enter the administrator credentials established when MobileIron Sentry was installed. 3. Enter "enable". 4. When prompted, enter the "enable secret" set when MobileIron Sentry was installed. 5. Enter "configure terminal". 6. Enter the following command to enable FIPS: FIPS 7. Enter the following command to proceed with the necessary reload: do reload 8. Enter "Yes" at save configuration modified prompt. 9. Enter "Yes" at proceed do reload.
