Securing your Apache 2.x Server

SSL and PCI Compliance

Your SSL configuration should have the following options:

# This disables old, vulnerable SSL versions (SSLv2):
SSLProtocol -ALL +SSLv3 +TLSv1

# This disables WEAK and MEDIUM strength ciphers:

Testing Apache 2.x for SSLv2 Support

From a command prompt, run this command, making sure to enter your domain name and the port you want to check (default HTTP over SSL- 443):


You should get back something like this:

82841:error:1407F0E5:SSL routines:SSL2_WRITE:ssl handshake failure:/usr/src/secure/lib/libssl/../../../crypto/openssl/ssl/s2_pkt.c:428:

If you get back something else that looks like it worked/is doing something, then you have SSLv2 enabled, which is *bad*.
