Re: Patterns and Security Measurement



Hi,
There is no 'one way' to measure security because you
don't have a ruler accepted by everybody for that.
Instead, there are several aproaches...
One would be to perform an audit. Here you can choose
between ISO 17799 (more 'commercial' version) and all
the other standards that put together generated ISO
17799, or you can choose OSSTMM. Open source... you
know, more likeit. There are consistent differences
between the tow. ISO is theoretical while OSSTMM is
more practical. But you can do some googleing to
figure out what is best for you.
Another approach would be... surprise! a pen test. :)
But it seems the problem is a little bit complex for
this.
You can also try a risk management and vulnerability
assessment approach.

Remember that the best security solution money can buy
is worthless if it's not used correctly. The idea is
to develop the best security with the resources you
have.

Greets,
Dan

Hi list,

Actually, I am trying to measure security (and then
security assurance)
level of a complex telecommunication network. I am
looking for a
method/approach/product using sets of predefined,
standard entities
(station, server, firewall, router, ...) and
relations (forming
"patterns" like pipe, cluster, bus, gateway, ...,
architectures) which
have already been measured to simplify the process
of system security
measurement. An aggregation algorithm is then needed
to arrive at an
overall system security value.

Any recommendation of academic or industrial
solutions would be welcome.

Other suggestions for solving the problem (security
measurement of
complex network) are also greatly appreciated.

Many thanks,
Nguyen Pham.
