Cisco is Transitioning from FIPS 140-2 to FIPS 140-3

Encryption is paramount to offering integrity and confidentiality to guard our federal prospects’ information. There are lots of completely different cryptographic algorithms (equivalent to block cipher, symmetric and uneven algorithms) which can be out there that may encrypt and convert information into unreadable ciphertext. The tactic to do that have to be safe. Being Federal Data Processing Commonplace (FIPS) validated ensures that the encryption strategies used have been independently reviewed and examined earlier than being deployed. FIPS accredited algorithms, to incorporate the transition to the brand new FIPS 140-3 necessities, have endured intensive safety evaluation and are frequently examined to make sure that they may present enough safety.

The FIPS 140-3 timeline

The FIPS 140-3 normal supersedes FIPS 140-2, and it grew to become efficient September 22, 2019. Validation efforts beneath FIPS 140-3 started in September 2020.  FIPS 140-3 covers a large number of vulnerabilities and threats defining safety necessities for Cisco from preliminary design to operational deployment. On April 1, 2021, The Cryptographic Module Validation Program (CMVP) not excepted FIPS 140-2 submissions for brand new validation certificates and validation ended for FIPS 140-2 on September 22, 2021. These FIPS 140-2 modules can stay lively till September 21, 2026, then might be moved to the Historic Listing. Clients should purchase off the Historic Listing and use the FIPS 140-2 modules for current purposes solely. You possibly can can discover extra right here at NIST.

Cisco has a number of FIPS 140-3 validations in course of and can proceed to maneuver the portfolio of FIPS 140-2 validations to FIPS 140-3 over the following a number of years.

Cisco’s World Certification and Frequent Safety Modules Crew has carried out an modern method to expedite FIPS certifications. They’ve developed a crypto module that’s already FIPS-validated and will be embedded in Cisco merchandise. You will need to be aware that the crypto module is already FIPS-validated, so the Cisco product using it might probably declare compliance to FIPS 140.

What’s a cryptographic module?

A cryptographic module is a software program or {hardware} system/part that performs cryptographic operations securely implementing the cryptographic logic and processes that assist the safety capabilities in a pc or digital system. The Nationwide Institute of Requirements and Expertise (NIST) notes that the areas coated, associated to the safe design and implementation of a cryptographic module, embrace:

• Specification
• Ports and Interfaces
• Roles
• Companies
• Authentication
• Finite State Module
• Bodily Safety
• Operational Setting
• Cryptographic Key Administration
• Electromagnetic Interference/Electromagnetic Compatibility
• Self-Assessments
• Design Assurance and,
• Mitigation of different Assaults.

Cryptographic Modules that conform to FIPS make use of accredited safety capabilities equivalent to cryptographic algorithms, cryptographic key administration strategies, and authentication strategies.

Understanding FIPS 140-2

The FIPS 140-2 normal stipulates the safety necessities wanted by a cryptographic module. In a nut shell, FIPS 140-2 is a pc safety cryptography normal utilized by the USA Federal Authorities when cryptographic-based safety methods and telecommunication methods are used to offer safety of delicate however unclassified information as outlined in Part 5131 of the Data Expertise Administration Reform Act of 1996, Public Legislation 104-106. Cisco is required to satisfy this normal to have the ability to promote its merchandise into federal businesses such because the Intelligence Neighborhood and Division of Protection.

Defending cryptographic modules is important to keep up the confidentiality and integrity of the knowledge that’s being protected. The FIPS 140-2 normal bears 4 ranges of accelerating safety:

1. Safety Degree 1: Supplies fundamental safety necessities for a cryptographic module. Degree 1 should have no less than one accredited algorithm or accredited safety perform. No particular bodily safety mechanisms are required.
2. Safety Degree 2: Enhances the bodily safety mechanisms of a Safety Degree 1 cryptographic module by including the requirement of tamper-evidence (coatings or seals or decide resistant. Locks on detachable covers or doorways of the module). This degree additionally requires role-based authentication during which a cryptographic module authenticator permits the authorization of an operator to imagine a selected position.  The system should even be evaluated on the Frequent Standards analysis assurance degree EAL2 or greater.
3. Safety Degree 3: Along with the tamper-evident bodily safety mechanisms required at Degree 2, Safety Degree 3 necessities forestall an intruder from getting access to the crucial safety parameters (CSPs) held inside the cryptographic module. Bodily safety mechanisms at this degree can detect and reply to bodily entry, use, or modification. This degree additionally requires identity-based authentication mechanisms which boosts the safety offered by degree 2 role-based authentication mechanisms. The system should even be evaluated on the Frequent Standards analysis assurance degree EAL3 or greater.
4. Safety Degree 4: This degree offers the best degree of safety outlined in FIPS 140-2. The bodily safety mechanisms should present an entire envelope of safety across the cryptographic module with the intent of detecting and responding to all unauthorized makes an attempt at bodily entry. This degree additionally protects the cryptographic module towards environmental situations or variations of regular working ranges of voltage and temperature. Intentional junkets past the conventional working ranges could also be utilized by an attacker to bypass a cryptographic modules protection. The system should even be evaluated on the Frequent Standards analysis assurance degree EAL4 or greater.

FIPS 140-2 and FIPS 140-3 differentiation

NIST notes that the brand new FIPS 140-3 introduces some vital adjustments from FIPS 140-2. For instance, reasonably than encompassing the module necessities instantly, FIPS 140-3 references ISO/IEC 19790:2012. NIST additionally notes that the testing for these ISO/IEC 19790:2012 necessities might be outlined with ISO/IEC 24759:2017.

NIST goes on to say that there are few main technical requirement adjustments from FIPS 140-2 to FIPS 140-3, however the utilization of those ISO paperwork requires procedural adjustments within the administration and execution of the validation program and course of. FIPS 140-2 to FIPS 140-3 differentiation is as follows:

• When FIPS 140-2 was first written, encryption modules have been all {hardware} modules. Over time nevertheless, several types of modules have been created (e.g., software program and firmware modules, in addition to hybrid modules). The brand new FIPS 140-3 normal will embrace {hardware} modules, software program modules, hybrid-software modules, and hybrid firmware modules.
• FIPS 140-2 additionally restricted hybrid modules to solely a FIPS 140-2 Degree 1 validation certification. FIPS 140-3 doesn’t have this restriction, now a hybrid module will be validated at any degree within the new normal.
• FIPS 140-2 required {that a} module assist the next roles: person position, crypto officer position, and a upkeep position (this position was non-obligatory). The FIPS 140-3 normal nonetheless has these three roles, however the crypto officer position is the one one that’s required. Each the person position and the upkeep position are non-obligatory in FIPS 140-3.
• Inside ISO 19790 the FIPS 140-3 normal is just like the FIPS 140-2 normal the place Degree 1 has no authentication necessities, degree 2 has minimal role-based authentication, and degree 3 has identity-based authentication. The distinction now’s that FIPS 140-3 degree 4 authentication requires multi-factor id.
