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.

ℹ️ Check

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

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.
