Re: How BAD is SQL on ISA?

Hi Jim, et. al.,

SQL logging puts a considerable performance hit on the server, and if
you're hosting the database on the ISA Server itself, you may hit the
glass ceiling :-)

Generally speaking, stick to your "least privileges" concept; you can't
go
wrong there.
Perf, vulnerabilities and user rights become harder to control when you
have
multiple users accessing your firewall; even if only for SQL usage.

If $$ pushes you into that train track of thought, then make sure you:
1. set a strong password for the "sa" account and control database
access
permissions with an iron fist
2. don't provide direct access to the SQL admin account from outside (no
direct SQL calls); no PF for SQL access!
3. remove any master-db SP and XP that you don't need for normal SQL
operations; many vulnerabilities have been found therein.
4. No one, but NO ONE except the server admin gets administrative access
to
the SQL services!

Hi there

I live in a principle of least privileges and so I do not install
anything
on my ISA Server which is not absolutely CRUCIAL to the survival of my
Firewalling Strategy.

However, I have been considering the option to start logging all ISA
requests to a SQL Database as opposed to flat files which is currently
the
default logging method.

If I was to do this then I would like to keep the ISA Firewall
independant
of any other server and as a result I would need to install SQL Server
onto my ISA Firewall.

What I would like to know is this:
1) Is it at all a good idea to install a product such as SQL Server onto
my ISA Firewall?
2) How robust is ISA when it comes to logging to a SQL Database as
opposed
to the flat files?
3) How will it impact any Server Publishing rules that I have already
created on port 1433 (SQL Server)?

Cheers
William R.
