Information

Windows 11 must be configured to prioritize ECC Curves with longer key lengths first.

GROUP ID: V-253363
RULE ID: SV-253363r971535

Use of weak or untested encryption algorithms undermines the purposes of utilizing encryption to protect data. By default Windows uses ECC curves with shorter key lengths first. Requiring ECC curves with longer key lengths to be prioritized first helps ensure more secure algorithms are used.

Solution

Configure the policy value for

Computer Configuration >> Administrative Templates >> Network >> SSL Configuration Settings >> 'ECC Curve Order'

to 'Enabled' with 'ECC Curve Order:' including the following in the order listed:

NistP384
NistP256
