Remove SSL version Information
I was running a vulnerability application against our Linux server and it gave me this report.


TLSv1 Protocol is Enabled.
Supported Cipher : TLS1_DHE_RSA_WITH_AES_256_SHA SSL_NOT_EXP
SSLv3 Protocol is Enabled.
Supported Cipher : TLS1_DHE_RSA_WITH_AES_256_SHA SSL_NOT_EXP

How do I prevent Apache on Centos from displaying the above version information.

you can't prevent it! That's nuts! It's critical information for the client negotiating with you to have. Why on earth would you want to stop this information being available in the first place? Wy do you think it's a risk? AES256 with SHA? That's tough stuff. And SSL_NOT_EXP means "non-export grade SSL ciphers", i.e. "good SSL ciphers"

What is the supporting text with this report? Did you, or your management superiors, read it?

Thank you acid_kewpie for your response.
We are using McAfee's Vulnerability manager and were trying to bring down the number of reports such as the above we are seeing. I didn't know the client needed this information to use for authentication.

but is it actually being framed in a negative light in any way by this security service? As much as it's restrictive having a single cipher only, it's a very secure one. There is no perspective of risk in any way at all as I'm reading this. It's like saying you don't want to open your firewall to the internet for security reasons, but still want to run a website.

:rolleyes: McAfee, huh? :rolleyes:

Here's a kilogram of salt. You'll need it.

Thanks Guys.
It is information only and not being flagged as a vulnerability. This shouldn't be shown up in the first place so we'll talk to McAfee and get their input on what they think. I'm closing this thread as solved.
