SSL Cipher is an encryption algorithm, which is used as a key between two computers over the Internet. Data encryption is the process of converting plain text into secret ciphered codes.
It’s based on your web server SSL Cipher configuration and strong protocol that allows data encryption to take place.
So it’s important to configure SSL Cipher and enable above TLS 1.1 & TLS 1.1, which is stronger and not vulnerable.
RC4 & MD5 cipher algorithms are considered vulnerable ciphers.
- Go to
conffolder of your web server (or) edit your virtual host file
httpd-ssl.confas below to accept only higher encryption algorithms
- Set your Protocols to accept only TLSV1.2 and TLSv1.1. If you could afford it you can remove the TLS1.1 as well and keep only TLSv1.2 ( By doing this you can disable the SSLV2, SSLv3)
SSLCipherSuite HIGH:!MEDIUM:!aNULL:!MD5:!RC4 SSLProtocol +TLSv1.1 +TLSv1.2
Save the configuration file and restart apache server
Note: if you have many weak ciphers in your SSL auditing report, you can quickly reject them adding ! at the beginning. of whatever the cipher name is specified
