Ensure OCSP Stapling Is Enabled

RendahLevel 2Otomatisapache

Deskripsi

The OCSP (Online Certificate Status Protocol) provides the current revocation status of an X.509 certificate and allows for a certificate authority to revoke the validity of a signed certificate before its expiration date. The URI for the OCSP server is included in the certificate and verified by the browser. SSLUseStapling on must be set (no occurrence off) and an SSLStaplingCache must be configured. Reads the main configuration (APACHE_CONF overrides; default /etc/apache2/apache2.conf, /etc/httpd/conf/httpd.conf or /usr/local/apache2/conf/httpd.conf) and every Include/IncludeOptional file. CIS marks this recommendation Manual; the automated check implements its audit procedure.

Output yang diharapkan: compliant

Cara perbaikan

Metode perbaikan: Panduan atau patch infrastruktur

At server level: SSLStaplingCache "shmcb:logs/ssl_staple_cache(512000)" and SSLUseStapling On (also in each TLS virtual host). Then run apachectl configtest and reload Apache.
