FIPS 140-2 Validation: A Crucial Step for Secure Data Transmission
The rise of cyber threats and the increasing demand for protecting sensitive information have led organizations to prioritize content security. One of the ways businesses can ensure the highest level of security for their content is through FIPS 140-2 validation. This blog post provides a comprehensive understanding of FIPS 140-2 validation, its importance, and its role in ensuring secure content transmission.
What Is FIPS 140-2?
Federal Information Processing Standard 140-2, or FIPS 140-2, is a U.S. government security standard that defines the minimum security requirements for cryptographic modules used to protect sensitive information within computer and telecommunication systems. The standard was established by the National Institute of Standards and Technology (NIST) and is applicable to both hardware- and software-based cryptographic modules. The primary objective of FIPS 140-2 is to provide a benchmark for ensuring the security and integrity of sensitive content transmitted and stored within government and other security-focused organizations.
The FIPS 140-2 standard includes four security levels, ranging from Level 1 to Level 4, each providing an increasing degree of security. These levels are designed to cover a wide variety of potential applications, allowing an organization to select the appropriate level of security based on its needs and requirements. Level 1, for instance, offers the lowest level of security and does not require any physical protection, while Level 4 provides the highest level of security and requires complete physical protection and robust encryption techniques. We will further explore these levels below.
Organizations seeking FIPS 140-2 validation must undergo a rigorous testing and certification process to ensure their cryptographic modules meet the required security standards. This process is carried out by independent laboratories accredited by NIST, which perform a series of tests to evaluate the security features and functionality of the cryptographic module. Upon successful completion of the testing process, NIST issues a certificate validating the cryptographic module’s compliance with FIPS 140-2 standards.
Why Is FIPS 140-2 Essential?
FIPS 140-2 validation is particularly important for organizations that deal with sensitive information, such as government agencies, financial institutions, healthcare providers, and defense contractors. In fact, many government agencies, as well as organizations that contract with government agencies, are required to use FIPS 140-2 validated products to protect sensitive content. FIPS 140-2 validated products include encryption modules, virtual private network (VPN) gateways, and secure email systems. This requirement ensures a consistent level of security across government systems and helps prevent unauthorized access and data breaches.
FIPS 140-2 validation also holds significant value for private sector organizations that are not subject to federal regulations. By adopting FIPS 140-2 validated cryptographic modules, organizations demonstrate their commitment to content security and ensure the protection of sensitive information from potential cyber threats. FIPS 140-2 validation can also serve as a competitive differentiator, as it indicates that the organization’s products and services meet the highest security standards.
FIPS 140-2 Compliance Levels: What Are They?
As a U.S. government standard, FIPS 140-2 defines the security specifications for cryptography modules. Cryptography modules refer to a set of hardware, software, or firmware components that can perform cryptographic functions, such as hash functions (e.g., SHA-256, MD5), symmetric encryption (e.g., AES, DES), asymmetric encryption (e.g., RSA, ECC), and digital signatures (e.g., DSA, ECDSA).
FIPS 140-2 compliance levels refer to the different levels of security validation that a cryptography module (“module”) can achieve, according to the standard’s requirements. This validation is important for ensuring that the module can provide the required level of security for transmitting sensitive content.
It is worth noting that a product or implementation does not meet the FIPS 140-1 or FIPS 140-2 applicability requirements by simply implementing an approved security function and acquiring algorithm validation certificates. Only modules tested and validated to FIPS 140-2 meet the applicability requirements for cryptographic modules to protect sensitive information.
Four Different Levels of FIPS 140-2 Compliance
There are four different levels of FIPS 140-2 compliance that a cryptography module can achieve, each with its own set of requirements. These levels are Level 1, Level 2, Level 3, and Level 4. The higher the compliance level, the greater the level of security provided by the cryptography module. Here is an overview of the four FIPS 140-2 levels and their respective requirements for validation.
| FIPS 140-2 Level 1 | Level 1 is the lowest level of FIPS 140-2 compliance. At this level, the module provides some basic protection against unauthorized access. It uses algorithms that are widely available and used in common products, such as AES and SHA-1. However, there are no physical security mechanisms required at this level, meaning that anyone can access the module. |
| FIPS 140-2 Level 2 | At Level 2, physical security mechanisms must be implemented to protect the module. Examples of these mechanisms include tamper-evident coatings, seals, or casings that can detect and alert of any unauthorized access attempts. This level also requires that certain types of algorithms be used, such as triple-DES and hash-based message authentication codes (HMAC). |
| FIPS 140-2 Level 3 | Level 3 requires additional physical security mechanisms, such as sophisticated sensors that can detect physical tampering. It also requires that the module use algorithms that provide greater protection against attacks, such as RSA and DSA. At this level, the module must protect against unauthorized access, physical tampering attempts, and attempts to bypass security mechanisms. |
| FIPS 140-2 Level 4 | Level 4 is the highest level of FIPS 140-2 compliance. It includes all the requirements of Level 3, plus additional mechanisms that can detect and respond to tampering attempts in real time. For example, the module must be able to detect and respond to physical attacks, such as laser attacks or attempts to freeze the module. This level also requires that the module use algorithms that provide the highest levels of security, such as elliptic curve cryptography (ECC) and digital signature algorithm (DSA) with at least 3072-bit keys. |

Benefits of FIPS 140-2 Validation
Obtaining FIPS 140-2 validation offers several benefits for federal agencies, U.S. government contractors, and subcontractors, including:
- Increased security for content in transit and at rest, ensuring that sensitive information is protected from unauthorized access and tampering
- Compliance with various regulatory requirements, particularly for organizations that handle federal content like controlled unclassified information (CUI) and federal contract information (FCI), or are part of the U.S. government supply chain, like the Defense Industrial Base (DIB)
- Enhanced stakeholder trust and confidence in your organization, as FIPS 140-2 validation demonstrates a commitment to securing sensitive content
FIPS 140-2 Validation Process
The FIPS 140-2 validation process is conducted through the Cryptographic Module Validation Program (CMVP), which is jointly managed by NIST and the Canadian Centre for Cyber Security (CCCS). The process involves the following steps:
- Selection of an accredited Cryptographic Module Testing (CMT) laboratory to perform the evaluation
- Submission of the cryptographic module and relevant documentation to the CMT laboratory
- Testing of the cryptographic module by the CMT laboratory to ensure compliance with FIPS 140-2 requirements
- Submission of the evaluation report by the CMT laboratory to CMVP for review and approval
- Issuance of a FIPS 140-2 validation certificate by CMVP upon successful completion of the review
It’s important to keep in mind that the validation process can be time-consuming and complex, so organizations should plan accordingly.
FIPS 140-2 Validation Requirements
FIPS 140-2 consists of several requirements that cryptographic modules must meet for validation. Some of these requirements include:
- Physical security requirements, such as tamper-evident seals and secure enclosures for higher compliance levels
- Cryptographic module specification requirements, including the use of approved algorithms and key sizes
- Operating system and software requirements, such as the need for secure boot mechanisms and the use of cryptographic random number generators
FIPS 140-2 Validation Challenges
While FIPS 140-2 validation offers significant benefits, organizations may encounter various challenges in achieving validation, including:
- Cost considerations, as the validation process can be expensive, particularly for small and medium-sized businesses
- Time constraints, as the validation process can take several months to complete
- Technical expertise requirements, as organizations may need to engage specialized resources to navigate the complex validation process
FIPS 140-2 Validation and Its Role in Achieving NIST 800-171 Compliance
NIST 800-171 is a standard that provides guidelines for protecting sensitive government content. The framework applies to organizations that provide services to the government or handle sensitive government content. NIST 800-171 requires contractors and subcontractors who process, store, or transmit CUI to implement and maintain the security controls outlined in the publication. One of these controls is the use of cryptography to protect CUI during transmission and storage. Specifically, NIST 800-171 mandates the use of FIPS 140-2 compliant cryptographic modules to ensure the security of CUI.
