You can configure the Web GUI to support the National Institute of Standards and Technology (NIST) SP800-131a security standard. SP800-131a requires longer key lengths and stronger cryptography than other standards, for example, FIPS 140-2. SP800-131a requires Transport Layer Security (TLS) V1.2.
You can run SP800-131a in two modes: transition and strict. Use the transition mode to move gradually towards a strict enforcement of SP800-131a.
The transition mode allows the use of weaker keys and algorithms than strict enforcement. The transition mode also allows the use of TLS v1.0 and v1.1.
As a consequence, transition mode is useful for upgrading security settings from FIPS 140-2, because you can continue to use existing FIPS 140-2 compliant certificates.
