I attended B-Sides in Orlando FL where one of the speakers had mentioned a site which contains hardened configs for popular services such as apache and postfix. The author of these configs is anonymous and although he doesn't claim to be an expert most would agree his configs are pretty locked down. I want to say it's "clipso" something but I'm not entirely sure.

Does anyone happen to know this source, or another good source which has hardened base configurations. I'd like to use these as a "wide-net" starting point to hardening some servers.

  • B-Sides in Orlando FL. The guy was giving a talk about SDR (software defined radios) and mentioned it.

  • I don't think it wasn't recorded... :(. It doesn't have to be that particular source. Is there another "go-to" source that is pretty popular in the community?

    A quick check of the BSides Orlando site showed the speaker was Lee V. Mangold. Google his name, leemangold.com comes up. You can probably ask him directly. The two answers offered so far (CSI and NIST) are right on the money, good references there. Many, many other tools too.

The first repository that comes to my mind for secure baselines is NIST.

You can review the baselines for various software and operating systems, inluding Apache here: http://web.nvd.nist.gov/view/ncp/repository


One option for this would the Center for Internet Security . Their Security Benchmarks cover a relatively wide range of systems and generally have some useful information in there.


There is also the DISA STIG (Security Technical Implementation Guide) website - it has hardening guides for a wide range of technologies, including some of the software you mentioned: http://iase.disa.mil/stigs/a-z.html
