The VPN Gateway must generate unique session identifiers using FIPS-validated Random Number Generator (RNG) based on the Deterministic Random Bit Generators (DRBG) algorithm.

Description
Both IPsec and TLS gateways use the RNG to strengthen the security of the protocols. Using a weak RNG will weaken the protocol and make it more vulnerable. Use of a FIPS validated RNG that is not DRGB mitigates to a CAT III.

Check Text ( C-7486r378299_chk )
Verify the VPN Gateway generates unique session identifiers using FIPS-validated Random Number Generator (RNG) based on the Deterministic Random Bit Generators (DRBG) algorithm. If the VPN Gateway does not generate unique session identifiers using FIPS-validated Random Number Generator (RNG) based on the Deterministic Random Bit Generators (DRBG) algorithm, this is a finding.

Fix Text (F-7486r378300_fix)
Configure the VPN Gateway to generate unique session identifiers using FIPS-validated Random Number Generator (RNG) based on the Deterministic Random Bit Generators (DRBG) algorithm.
