RE: Is there any way to measure IT Security??

We have been struggling for years in infosec to get discrete metrics.
One of the challenges is that these are complex heterogeneous systems
changing on a daily basis, if not more often. 

I have some personal biases with respect to assessment methodologies.  

ISO17799/BS7799 lacks likelyhood determination in it's measurement of
risk (e.g. a hurricane is rated just as high in N. Dakota as it is in
Miami, Florida), and lacks operational guidance useful after the
assessment (e.g. remediation guidance).  Having said this, it is a good
starting point for an immature security program and can be delivered
much more cost effectively than other, more robust methodologies.  Note:
ISO costs $995 per copy/update.  I'm not a big fan of that, but I
understand the need to support development.

NSA-IAM started out of the chute a few years back with a lot of
momentum, primarily I believe due to the "NSA" moniker attached to it.
It's a good methodology useful for evaluting critical systems and data.
I call it the "family jewels" methodology as it focuses not on your
organization as a whole, but rather on those assets you identify as most
critical.  In my opinion, a nice middle ground between ISO/BS/OCTAVE and
NIST.  Note:  NSA-IAM is freely available.  Russ Roger's folks at
SecurityHorizons deliver excellent certification in this methodology.

OCTAVE has a lot of street cred as it hails from the CMM folks.  Like
ISO, though, it lacks the likelihood determination component, and it not
as well vetted or robust as NIST 800, but does offer some of the same
advantages as ISO.

NIST is my personal favorite.  It's the most robust (and costly to
implement).  The upsides are that it provides a lot of post-assessment
guidance such as remediation methods, how to implement a CSIRT, etc.
The NIST 800-series is a continually updated set of "plug-ins" for the
800-26/800-30 modules used in the assessment phase.  There are 800
series documents for HIPAA, etc.  A NIST 800-30 assessment will capture
a great deal of organizational as well as technical information, and
categorizes your assets into "systems".  This makes the elephant
(remediation) easier to eat.  The other upside to NIST 800 is that it
provides a clear path to certification and accreditation, which the
other methodologies I mentioned do not.  It's well vetted in the
security community and embraded by the federal government.  Oh, and it's
freely available. All of it.

I mentioned that ISO can be less disruptive and costly to implement, but
if you can tolerate the additional cost (it's not extreme) and labor
required, you will be rewarded with deliverables that you can use to
identify your intial baseline and followup deltas to effectively and
objectively measure the effectiveness of your security dollars.  

Just my $0.02.

This is a good list, but somewhat incomplete.  I think you should
consider that security is not a destination, it is a process.  There are
plenty of sources out there that you can measure yourself against, from
a process point of view.  Check out the ISO17799 standard or the BS7799
standard, they outline the processes which go into a well developed
security program.  Or look at the Generally Accepted Information
Security Principles (under development -
http://www.issa.org/gaisp/gaisp.html).

The NSA IAM/IEM is a methodology for managing controlled
penetration/vulnerability for a particular system/app.  The OWASP is for
web application testing.  These might give you an idea of security
posture of one server or application, but not overall for your company.
This kind of testing makes up a small amount of managing a secure
organization. 

Take a look at the new ISO version, 2005.  This fall, there will be a
different ISO standard, 27001, which will allow a company to be
certified against the standard.
http://www.iso.org/iso/en/commcentre/pressreleases/2005/Ref963.html

Hope that helps.

Basically IT Security covers a gamut of areas, i am just listing some ,
on the fly

* Antivirus Solutions
* Intrusion Prevention
* Intrusion Detection
* Patch Management
* Firewall
* VPN Gateway
* Vulnerability Assessment & Reporting
* Identity Access Management (single-sign-on, SOX/HIPAA/GLB
compliance....)
* Network Security
* Security Policy Compliance Management
* AntiSpam (mail protection software)
* Web Content Filtering

I'm not sure whether we have one-size-fits-all solution which can help
us in measuring your enterprise IT Security posture.

I can list some good tools i have come across personally like NMap,
ScanFi, Nessus, IdentityAccess Manager,GFI ....but the list is endless,
so give them a try in google :-)

Google Risk reporting and you will get whole list of research links.
It would also be helpful to look at owasp www.owasp.org HTH Regards,

You should check out NSA IAM/IEM Methodology...it works well for me.

Dear all,

Currently I'm looking for a tool, or a technique to measure IT
security?

The baseline for security is CIA (Confidentiality, Integrity and 
Availability), that is every organization which want to called 
secure must be guarantee that their system comply this matter.

But the problem is, we need a tool/technique to measure how secure 
are we. Therefore, wee need a tool/technique to measure how close 
that our system status now to CIA.

Please share your experience about this matter.

If there any link about this issue, I really appreciate if you share

to us (You may contact me privately) .

Best Regs,

Toto
