[users@httpd] nmap shows SSLv3 still active in Apache
Hello,
My security team has asked that we completely disable SSLv3 on our Apache
configurations. We've run the SSLProtocol commands in the ssl.conf file
(like SSLProtocol ALL -SSLv2 -SSLv3 as an example) and we've used the
SSLCipherSuite commands also, but when we run nmap against the Apache
server we get 'SSLv3: No supported ciphers found' below, which our security
team won't accept.

If I run nmap against say a Tomcat server, I don't see SSLv3 at all:

So my question is: does anyone know if there is a way to make sure that
SSLv3 does not show up on an nmap scan for an Apache server? Is there any
sort of additional configuration on the Apache side that can be done?
Please let me know if additional clarification is necessary. Thank you for
the time
Dan
