Check to see if the town/county has any policies in place for computer systems and networks for public services and follow those guidelines.

Otherwise look at surrounding public library systems to see if they have any you can adopt.

For a LAMP setup your definitely going to want to use selinux to limit what each application can read and write to, and you should use audit too to set auditing on sensitive directories like, /etc, /bin, /lib, /sbin, /usr/bin, /usr/lib, /usr/sbin.

You will probably want to use smartmon to monitor drive health and something else to monitor resource usage (drive space, memory, cpu, mysql db space) with email/sms alerts.

Thanks for your very detailed response. Though I can't help feeling a
bit like having asked for an identity photo... and getting a 10-foot oil
painting :oD

Basically, all I'm concerned about security-wise is a modest
Apache/PHP/MySQL server running a single public library management
software, and interconnecting eleven (small) public libraries, with a
total of 60.000 database entries. No (very) big deal.

The configuration is supposed to run on a dedicated server, so my
question will be more practical:

- Is it worth the hassle to bother with SELinux?

- Is the standard firewall configuration enough, or do I really have to
fine-tune the thing?

- Basically, what auditing tools besides NMap can you recommend for such
a thing?

cheers,

Niki
