Greetings fellow computer junkies...

*** I am inviting any hardening offers ***

I am recovering from a disaster hardening incident.

I hired this company to harden our new FreeBSD server.

He took about 22 hours to finish. Yea, this scarred me some...

Then when fixes needed applying the next day, he took another 15 or so hours to set up dns and 1 domain ( Direct Admin ).

That last part was my idea, since the set-up was not right when i was setting up domain 1, I figured to get him to get the first domain 1 so the rest would not run into any problems. My mistake.

At this point with this person in the box for about 36 hours now I am extremely unsure of what is on my box and how secure it really is, at least from that person anyway.

Oh, I should add that he refused to disclose what exactly he did. When I requested a summery, he sent this summery:

> This list is not complete but here is what I have on
> the list:
>
> - firewall installation and configuring
> - secure level increased to level one
> - web server configured to be protected by mod_sec
> against code injection, dos and remote exploits
> transmitted over http
> - kernel configured against traffic storm attacks
> - /tmp has been secured
> - direct root login disabled
> - proftpd disabled per customer request then re
> enabled per customer request
> - syslogd remote logging disabled


Which as I see it tells me basically nothing in terms of supporting the server and or the hardening that was preformed.


So, for lack of any other solution, we are reformatting the HD and rebuilding. This has cost me allot, but without the peace of mind, what's the point in hardening, why not just let everyone one have a big old Orgy with your server right ?

Bullsh**... I hope I am not the only one who see this the way i am, because i could be wrong about this guys service, but i think I have a right to know exactly what he did - don't I ?

======= SOLUTION ===============

I am considering another service.

This one includes the following - and I would appreciate any feedback to help me plug any holes it may have, it seems like some of the stuff listed is not for a New box, or some of it is redundant, and in my limited view, it seems a little incomplete.

Maybe I'm wrong here too, please advise.

Smartd (HDD Reliability monitor)
MRTG / RRDTool (Bandwidth Usage Monitor) ? DirectAdmin does this.

I used to be a security consultant (4 years ago) and I use DA on FreeBSD but I'm not sure what you try to say here. Is it that you are asking us to confirm that the first person ripped you off and if the second offer is better? Are you saying that DA running on a FreeBSD box is insecure?
