I Agree with you Larry. However, I´m not sure if accept the initial risk
wiht no actions to try to mitigate it will be accepted, because one
organization can do it for all the assets/risks identified and then not
to select and to implement controls at all... I ACCEPT THE RISK...and I
don´t do anything this is my ISMS.???
One thing that must be clear in the SOA is which assets (Windows NT) are
related to which Threats and Vulnerabilities (not only technical ) and
then, the risk derived from this relation and how to control it (controls
selected and implemented)
In this case, it´s important to know the risk for the organization derived
from using W-NT, the services and applications that are running on these
servers, how the whole inormation and the organization´s processes are
related and affected in case the servers will be compromised, and
finally, the organization has to "say" the reason "WHY" it doesn´t do
anything to mitigate the risk. Costs?, No risk?, no Budget?, Future plans
to migrate to another solutions-when? etc.
In some cases when there is no way to implement controls inmediatly, It
could be ussefull to show an action plan in order to correct the problem
and mitigate the risk in the near future. And it´ll be revised in the
Remenber, the Direction (General Manager and Security Comitee) has to know
the risks and aprove the options selected.

Risk is a local judgement. But remember that many of those Microsoft
patches are regarding network vulnerabilities. So long as the machines
in question have no way of connecting to the Internet, some degree of
safety from automated attacks is provided.
That leaves the risk of insider attacks. Even if there is no ability
to connect to the Internet, the phrase "lot of Windows NT servers"
implies there are a lot of insiders, increasing the opportunity for

That depends on who the auditors are and the nature of the data/business.

That depends on what the objections are.
