Reconfiguration Step Before Enabling FIPS-140-2 Mode

You must disable all trap targets with authPriv/authNoPriv securityLevel.

Example:

admin@sbc1% show oam snmp trapTarget EMS_-10.54.71.176
ipAddress 10.54.71.176;
port 162;
trapType v3;
targetUsername emstrapuser;
targetSecurityLevel authPriv;
state enabled;
admin@sbc1% set oam snmp trapTarget EMS_-10.54.71.176 state disabled

Enable FIPS-140-2 mode

The SBC Core supports FIPS 140-2 level 1 certification for its cryptographic modules. It implements FIPS 140-2 Level 1 validated cryptographic hardware modules and software tool kits and operates this module in FIPS 140-2 approved mode for all cryptographic operations.

The following activities were made to achieve FIPS 140-2 certification:

• Self-Tests – The SBC implements cryptographic algorithms using software firmware and hardware and the modules perform various self-tests (power-up self-test, conditional self-test, and critical function self-test) to verify their functionality and correctness. If any of the tests fail, the module goes into “Critical Error” state and it disables all access to cryptographic functions and Critical Security Parameters (CSPs). The management interfaces do not respond to any commands until the module is operational. The Crypto Officer must reboot the modules to clear the error and return to normal operational mode.

  Self-tests are performed only when the system is running in FIPS 140-2 mode.

  
  The various self-tests are as follows:

  • Power-Up self-tests – The SBC performs self-tests at power-up to verify the integrity of the firmware images and the correct operation of the FIPS-approved algorithm implementation in the modules
  • Conditional self-tests – The SBC implements conditional self-tests such as Continuous Random Number Generator Tests (CRNGT), RSA Pair-wise Consistency Tests, Firmware Load Tests, and so on.
  • Critical function tests – The SBC implements the SP 800-90A CTR_DRBG as it's random number generator. The SP 800-90A specification requires that certain critical functions are conditionally tested to ensure the security of the DRBG. Therefore, the critical function tests are implemented by the cryptographic modules.

• FIPS Finite State Model- 

  The ability to change the FIPS  40-2 mode is reserved only for users having Administrator permissions; the Administrator is a role in the SBC that may be assigned to a Crypto Officer in a FIPS-compliant system.

• Install/upgrade Software Integrity Check – Software updates or patches to load onto the machine are automatically checked for integrity by validating Ribbon provided signature file for the particular package. (Refer to the install/upgrade guide). A failure in validation causes the installation/upgrade to abort.

• TLS v1.1 and v1.2 support for EMA/PM and SIP/TLS- TLS v1.1 and v1.2 provide resistance to certain known attacks (e.g. the BEAST attack affecting TLS v1.0) against earlier TLS versions and offer additional cipher suites not supported with TLS v1.0.

  Although TLS v1.0 and v1.2 are enabled by default, Ribbon recommends disabling v1.0 (if possible) in favor of the more-secure TLS v1.2, if browser support (for EMA/PM) and SIP peer interoperability (for SIP/TLS) considerations permit.

• Configuration database encryption key regeneration support – The System Administrator can cause the encryption keys used to protect sensitive information in the configuration database to regenerate.

• SSH key regeneration support – The System Administrator can regenerate the RSA keys used by the SBC to authenticate itself for SFTP and for CLI and netconf over ssh at any time.
• Enabling FIPS-140-2 mode
  The FIPS compliant operating mode is a mode of system operation that is fully compliant with FIPS-140-2 at security level 1+. Putting the system in FIPS-140-2 operating mode requires enabling the fips-140-2 mode parameter as well as configuring other parameters. 
  

To enable Fips-140-2 mode

1. On the SBC main screen, go to Administration > Users and Application Management > Fips-140-2.
   The Fips-140-2 window opens.

2. In Admin, select the name of the SBC system.
   The Edit Fips-140-2 options open.

   

3. Use the Mode option to enable Fips-140-2 mode.

Reconfiguration Steps After Enabling FIPS-140-2 Mode

After enabling FIPS-140-2, you must reconfigure the keys (authKey/privKey) for all SNMP users (this applies to all SNMP users for authPriv/authNoPriv security level trap targets).

1. Use the following CLI commands to reconfigure the keys:

   admin@sbc1% set oam snmp users emstrapuser authKey Xd:aa:1f:09:75:6e:f6:da:NN:NN:NN:NN:NN:0d
   admin@sbc1% set oam snmp users emstrapuser privKey Xd:aa:1f:09:75:6e:f6:da:NN:NN:NN:NN:NN:0d
   admin@sbc1% commit

2. Enable the authPriv/authNoPriv trap targets:

   admin@sbc1% set oam snmp trapTarget <trap_target_IP> state enabled
