To change the TLS configuration settings
1
Make a backup of the
skyboxwebadmin.conf
file.
2
Open the
skyboxwebadmin.conf
file (with vi).
3
Comment out the default security configuration by adding “
#
” at the beginning
of the SSLProtocol and SSLCipherSuite lines.
#Default Security configuration for SSL
SSLProtocol All +TLSv1.2 +TLSv1.1 +TLSv1
SSLCipherSuite
ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES25
6-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AE
S128-GCM-SHA256:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256:ECDHE-RSA
-AES256-SHA

Uncomment either High or Medium (not both) by deleting “
#
” from the
appropriate SSLProtocol & SSLCipherSuite lines.
Note: Do not uncomment the title line itself (High/Medium Security).
