Ensure Online Certificate Status Protocol (OCSP) stapling is enabled

SedangLevel 1Otomatisnginx

Deskripsi

OCSP stapling allows a server to efficiently deliver certificate revocation information to the client, improving performance and privacy. The server caches the OCSP response from the Certificate Authority (CA), eliminating the need for the client to make a separate connection. All four directives must be present: ssl_stapling on, ssl_stapling_verify on, ssl_trusted_certificate and resolver. Evaluated on the merged configuration printed by `nginx -T` (all included files; needs permission to read them). CIS marks this recommendation Manual; the automated check implements its audit procedure.

Output yang diharapkan: compliant

Cara perbaikan
