How to Properly Secure SSL/TLS Apache Settings against Heartbleed Poodle (TLS) Poodle (SSLv3) FREAK BEAST CRIME

Many users still are not aware but simply patching OpenSSL does not secure you against many known and easy to exploit attacks that will render your encryption useless by an attacker.

Use the following setings in /etc/httpd/conf.d/ssl.conf
 

SSLCipherSuite "EECDH+ECDSA+AESGCM EECDH+aRSA+AESGCM EECDH+ECDSA+SHA384 EECDH+ECDSA+SHA256 EECDH+aRSA+SHA384 EECDH+aRSA+SHA256 EECDH EDH+aRSA !CAMELLIA !SEED !3DES !RC4 !aNULL !eNULL !LOW !MD5 !EXP !PSK !SRP !DSS"
SSLProtocol -all +TLSv1.2 -SSLv3 -SSLv2

The above passed all tests on RapidSSL https://cryptoreport.rapidssl.com/checker/views/certCheck.jsp

Vulnerabilities checked:
  • Heartbleed
  • Poodle (TLS)
  • Poodle (SSLv3)
  • FREAK
  • BEAST
  • CRIME

Essentially what the above does is disable all known exploitable/weak ciphers and forces only TLS1.2 which is the only known secure version of TLS at this moment.  The settings above protect you against the listed vulnerabilities (just make sure you have a recent enough OpenSSL version that does support TLS 1.2, older distributions such as Centos 5 do not).
