TMA-APACHE-7.6
Ensure Insecure SSL Renegotiation Is Not Enabled
Deskripsi
A man-in-the-middle renegotiation attack was discovered in SSLv3 and TLSv1 in November, 2009 (CVE-2009-3555). First, a work around and then a fix was approved as an Internet Standard as RFC 574, Feb 2010. The work around, which removes the renegotiation, is available from OpenSSL as of version 0.9.8l and newer versions. For details ... SSLInsecureRenegotiation must be absent or off. 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.
