Confusion over Physical Assets, Information Assets – Part Two

So I need to compile a list of ALL assets, information or otherwise,

NO!
That leads to tables and chairs and powerbars.

OK so you can’t work without those, but that’s not what I meant.

InfoAssetsPhysical assets are only relevant in so far as they part of information processing. You should not start from those, you should start from the information and look at how the business processes make use of it.  Don’t confuse you DR/BC plan with your core ISMS statements.  ISO Standard 22301 addresses that.

This is, ultimately, about the business processes. Continue reading Confusion over Physical Assets, Information Assets – Part Two

Confusion over Physical Assets, Information Assets in ISO-27000

I often explain that Information Security focuses on Information Assets.

Some day, on the corporate balance sheet, there will be an entry

The thing is there are differing types of information and differing types of containers for them. Continue reading Confusion over Physical Assets, Information Assets in ISO-27000

On one of the ISO-27000 lists I subscribe to I commented that one should have a policy to determine the need for and the criteria for choosing a Data Loss Prevention mechanism.

I get criticised occasionally for long and detailed posts that some readers complain treat them like beginners, but sadly if I don’t I get comments such as this in reply

  Data Loss is something you prevent; you enforce controls to prevent data
  leakage, DLP can be a programme, but , I find very difficult to support
  with a policy.

Does one have visions of chasing escaping data over the net with a three-ring binder labelled “Policy”?

Let me try again.

Fly Away

Policy comes first.
Without policy giving direction, purpose and justification, supplying the basis for measurement, quality and applicability (never mind issues such as configuration) then you are working on an ad-hoc basis. Continue reading Does ISO 27001 compliance need a data leakage prevention policy?
