What is the basic level for the FIPS 140-2 Encryption Standard?

The FIPS 140-2 Encryption Standard specifies four levels of security, with Level 1 being the most basic and foundational level. Level 1 requires that the cryptographic module implements at least one approved algorithm for encryption, ensuring basic security for data protection. This level does not include stringent requirements for physical tamper resistance or operational environment, making it accessible for a wide range of applications that require minimal encryption standards.

As the levels progress to 2, 3, and 4, the requirements for security become increasingly rigorous, incorporating additional criteria such as physical security measures, key management, and enhanced testing for reliability and robustness. However, when discussing the most basic level, it is clear that Level 1 serves as the entry point for compliance with the FIPS 140-2 standards.
