MobileIron Sentry must generate unique session identifiers using a FIPS 140-2 approved random number generator.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-250997	MOIS-ND-000580	SV-250997r802213_rule		Medium

Description
Sequentially generated session IDs can be easily guessed by an attacker. Employing the concept of randomness in the generation of unique session identifiers helps to protect against brute-force attacks to determine future session identifiers. Unique session IDs address man-in-the-middle attacks, including session hijacking or insertion of false information into a session. If the attacker is unable to identify or guess the session information related to pending application traffic, they will have more difficulty in hijacking the session or otherwise manipulating valid sessions. This requirement is applicable to devices that use a web interface for device management.

Check Text ( C-54432r802211_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 set at MobileIron Sentry installation. 3. Enter "enable". 4. When prompted, enter the "enable secret" set at MobileIron Sentry installation. 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.

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 set at MobileIron Sentry installation.
3. Enter "enable".
4. When prompted, enter the "enable secret" set at MobileIron Sentry installation.
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-54386r802212_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 set at MobileIron Sentry installation. 3. Enter "enable". 4. When prompted, enter the "enable secret" set at MobileIron Sentry installation. 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 saved configuration modified prompt. 9. Enter "Yes" at proceed do reload.
