FIPS Certified Algorithms

GoSilent deploys AES 256-bit encryption to protect sensitive data via dual tunnel, end-to-end encryption. Data never gets stored on an intermediary server, and no extra keys are ever generated.


Using two nested, independent encryption tunnels helps to protect the confidentiality and integrity of data as it moves through an untrusted network. Each of the two tunnels helps protect data flow by using one of two independent encryption protocols:

  • Internet Protocol Security (IPsec) generated by a Virtual Private Network (VPN) Gateway
  • Media Access Control Security (MACsec) generated by a MACsec Device.

The outer tunnel of a dual tunnel VPN refers to the components that terminate the outer layer of encryption.

GoSilent utilizes AES 256-bit encryption for the outer tunnel to protect your private data and keeps it fully encrypted end-to-end. Data is never stored on an intermediary server. In keeping with Top Secret level encryption standards, there are no extra keys. Attila Security does not record, copy or have access to the encryption codes. This means that your data remains secure, even if compromised.

A Federal Information Processing Standard (FIPS) is a publicly announced standardization developed by the United States federal government for use in computer systems by all non-military government agencies and by government contractors, when properly invoked and tailored on a contract.

The 140 series of Federal Information Processing Standards (FIPS) are U.S. government computer security standards that specify requirements for cryptography modules.

SonicWall UTM appliances are FIPS 140-2 certified. The overall FIPS validation level for SonicWall UTM appliances is Security Level 2. A special FIPS SonicOS firmware, SonicOS, is available for download at mysonicwall.com. The SonicOS FIPS/CC release is certified for Level 3 Cryptographic Module Specification and Level 3 Design Assurance and is supported in NSA 3500 and above. For more information, refer to the SonicOS_5.5.1.2_FIPS_CC_Release_Notes.

When operating in FIPS (Federal Information Processing Standard) Mode, the SonicWall security appliance supports FIPS 140-2 Compliant security. Among the FIPS-compliant features of the SonicWall security appliance include PRNG (Psuedo Random Number Generator) based on SHA-1 and only FIPS approved algorithms are supported (DES, 3DES, and AES with SHA-1).

SonicWall UTM appliances are not configured to operate in FIPS-mode by default. This article describes the steps that must be taken to enable FIPS-mode operation.


FIPS-mode Operation

SonicWall UTM appliances are not configured to operate in FIPS-mode by default. The following steps must be taken to enable FIPS-mode operation.

  • Minimum password length in the Administration settings can not be less than 8
  • Admin or Users password can not be less than 8 characters
  • LDAP can not be enabled in FIPS mode without being protected by TLS
  • LDAP can not be enabled in FIPS mode without selecting 'Require valid certificate from server'
  • LDAP can not be enabled in FIPS mode without a valid local certificate for TLS
  • RADIUS can not be enabled with a shared secret shorter than 8 characters
  • RADIUS can not be enabled without being protected by IPSEC VPN
  • When creating VPN tunnels, ensure ESP is enabled for IPSec.
  • VPN Policy pre-shared key length must be longer than 8 characters.
  • Use FIPS-approved encryption and authentication algorithms when creating VPN tunnels. The SonicWall UTM appliance supports the following FIPS-approved cryptographic algorithms:
    • AES (128, 192, and 256-bit) in CBC mode (Cert. #1200)
    • Triple-DES in CBC mode (Cert. #868) 
    • SHA-1 (Cert. #1105) 
    • DSA (Cert. #398) 
    • RNG (Cert. #664) 
    • RSA (Cert. #577) 
    • HMAC-SHA-1 (Cert. #697) 
  • Only support IKE DH Group 14, 19, 20, 21 in FIPS mode
  • Only support AES CBC for IKE Phase 1/2 Encryption in FIPS mode
  • Only SHA-256 Authentication or higher is allowed in FIPS mode
  • IKEv2 Dynamic Client Proposal in VPN advanced settings requires SHA-256 or higher
  • IKEv2 Dynamic Client Proposal in VPN advanced settings requires AES
  • IKEv2 Dynamic Client Proposal in VPN advanced settings requires DH Group 14, 19, 20, 21
  • HTTP, SSH, and SNMP Management are not allowed in FIPS Mode.
  • Do not enable Advanced Routing Services.
  • Management via Group VPN is not allowed in FIPS mode.
  • Bandwidth Management has to be on.

When configured to operate in FIPS mode, the SonicWall UTM appliance provides only FIPS 140-2 compliant services.

To enable FIPS mode, navigate to Manage | Settings. Click on Settings gear. On the pop-up window, go to FIBS, then check Enable FIPS Mode and click Apply. The FIPS mode configuration can be determined by checking the state of the Enable FIPS Mode checkbox on the Manage | Firmware & Backups | Settings page and verification of the preceding steps. If the Enable FIPS Mode checkbox is enabled, the module is running in the FIPS Approved mode of operation.

Enabling FIPS Mode

Select Enable FIPS Mode to enable the SonicWall UTM appliance to comply with FIPS. When you check this setting, a dialog box is displayed with the following message:

Warning! Modifying the FIPS mode will disconnect all users and restart the device. Click OK to proceed.

Click OK to reboot the SonicWall in FIPS mode. A second warning displays. Click Yes to continue rebooting. To return to normal operation, Uncheck the Enable FIPS Mode check box and reboot the SonicWall UTM appliance into non-FIPS mode.

CAUTION:When using the SonicWall UTM appliance for FIPS-compliant operation, the tamper-evident sticker that is affixed to the SonicWall UTM appliance must remain in place and untouched.

FIPS Mode - an explanation

NSS has a "FIPS Mode" that can be enabled when NSS is compiled in a specific way. (Note: Mozilla does not distribute a "FIPS Mode"-ready NSS with Firefox.) This page attempts to provide an informal explanation of what it is, who would use it, and why. 

What's a FIPS?

The United States government defines many (several hundred) "Federal Information Processing Standard" (FIPS) documents.  (FIPS sounds plural, but is singular; one FIPS document is a FIPS, not a FIP.)  FIPS documents define rules, regulations, and standards for many aspects of handling of information by computers and by people.  They apply to all US government employees and personnel, including soldiers in the armed forces.  Generally speaking, any use of a computer by US government personnel must conform to all the relevant FIPS regulations.  If you're a US government worker, and you want to use a Mozilla software product such as Firefox, or any product that uses NSS, you will want to use it in a way that is fully conformant with all the relevant FIPS regulations.  Some other governments have also adopted many of the FIPS regulations, so their applicability is somewhat wider than just the US government's personnel.

What is "FIPS Mode"?

One of the FIPS regulations, FIPS 140, governs the use of encryption and cryptographic services.  It requires that ALL cryptography done by US government personnel MUST be done in "devices" that have been independently tested, and certified by NIST, to meet the extensive requirements of that document.  These devices may be hardware or software, but either way, they must function and behave as prescribed.  So, in order for Mozilla Firefox and Thunderbird to be usable by people who are subject to the FIPS regulations, Mozilla's cryptographic software must be able to operate in a mode that is fully compliant with FIPS 140.  To that end, Mozilla products can function in a "FIPS Mode", which is really "FIPS 140 Mode", when paired with a compliant copy of NSS.  (Note, the current version of FIPS 140 is revision 2, a.k.a. FIPS 140-2.  FIPS 140-3 is being devised by NIST now for adoption in the future.)  Users who are subject to the FIPS regulations must ensure that they have Mozilla's FIPS Mode enabled when they use Mozilla software, in order to be fully conformant.  Instructions for how to configure Firefox into FIPS mode may be found on support.mozilla.com.

Is NSS FIPS-140 compliant?

Mozilla's NSS cryptographic software has been tested by government-approved independent testing labs and certified by NIST as being FIPS 140 compliant when operated in FIPS mode on 4 previous occasions.  As of this writing, NSS is now being retested to be recertified for the fifth time.  NSS was the first open source cryptographic library to be FIPS certified.  

What is FIPS Mode all about? 

A FIPS-140 compliant application must do ALL of its cryptography in a FIPS-140 certified "device".  Whether it is hardware or software, that device will have all the cryptographic engines in it, and also will stores keys and perhaps certificates inside.  The device must have a way for users to authenticate to it (to "login" to it), to prove to it that they are authorized to use the cryptographic engines and keys it contains.  It may not do ANY cryptographic operations that involve the use of cryptographic keys, nor allow ANY of the keys or certificates it holds to be seen or used, except when a user has successfully authenticated to it.  If users authenticate to it with a password, it must ensure that their passwords are strong passwords.  It must implement the US government standard algorithms (also specified in other FIPS documents) such as AES, triple-DES, SHA-1 and SHA-256, that are needed to do whatever job the application wants it to perform.  It must generate or derive cryptographic keys and store them internally.  Except for "public keys", it must not allow any keys to leave it (to get outside of it) unless they are encrypted ("wrapped") in a special way.  This makes it difficult to move keys from one device to another, and consequently, all crypto engines and key storage must be in a single device rather than being split up into several devices.

How does this affect Firefox users?

These requirements have several implications for users.  In FIPS Mode, every user must have a good strong "master password", and must enter it each time they start or restart Firefox before they can visit any web sites that use cryptography (https).  Firefox can only use the latest version of SSL, known as "TLS", and not the older SSL 2 or SSL 3.0 protocols, and Firefox can only talk to those servers that use FIPS standard encryption algorithms such as AES or triple-DES.  Servers that can only use non-FIPS-approved encryption, such as RC4, cannot be used in FIPS mode.  

How is FIPS Mode different from normal non-FIPS Mode?

In normal non-FIPS Mode, the "master password" is optional and is allowed to be a weak short password.  The user is only required to enter his master password to use his own private keys (if he has any) or to access his stored web-site passwords.  The user is not required to enter the master password to visit ordinary https servers, nor to view certificates he has previously stored.  In non-FIPS mode, NSS is willing and able to use popular non-FIPS approved cryptographic algorithms, such as RC4 and MD5, to communicate with older https servers.  NSS divides its operations up into two "devices" rather than just one.  One device does all the operations that may be done without needing to authenticate, and the other device stores the user's certificates and private keys and performs operations that use those private keys.

How do I put Firefox into FIPS Mode?

Instructions for how to configure Firefox into FIPS mode may be found on support.mozilla.com. Some third-parties distribute Firefox ready for FIPS mode, a partial list can be found at the NSS wiki.
