update ssl due to insecurity


Hey all, we had a 3rd party company come in to check security, etc. and the only thing that showed up as a medium risk was the following;

Quote:
SSLv2 Supported:
This SSL service supports SSLv2 connections. SSLv3 has known cryptographic weaknesses. Secure web applications should only enable the SSLv3 or TLSv1 protocols.
They suggest disabling the use of SSL2 if possible, but I am not sure where to look.
The box uses SSL for secure transactions, but I am not familiar with just 'disabling' v2 and allowing 3, is this an apache change somewhere, a simple conf file change, etc.

I did find an idea googling, and in an included httpd-ssl.conf file found;
SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL

It can't be something as simple as changing that v2 to v3 is it?

Thanks for any replies.

According to http://www.debianadmin.com/how-to-en...che-hosts.html, yes, that is all that is needed. Although, you may want to copy their SSLCipherSuite and SSLProtocol lines.

Oh, and you then have to do the complicated task of restarting Apache .

Solved.

Perfect link, thanks. Just try searching for some of those leads to a few different way's, not testing, etc. but that worked perfect and the fact it had the test made it exactly what was needed.

Thanks.
