Transcripts
As the name implies, a gap analysis
is a study of where we are versus
where we would like to be.
And in the world of IT security, we
are constantly performing gap analyses
to be able to understand exactly what security is going
to be needed in the future.
Although this is very simple to explain,
it's a relatively complex process
to perform the analysis of what's actually
going on in your environment and putting together
a plan of how to get from where you are to where you're going.
As you might imagine, trying to understand every aspect of IT
security and how it applies to your organization
can be a very involved process.
And this is something that commonly
takes a number of weeks, months, or even years to compile.
As you can imagine, this might involve
a number of different people in your organization.
And there is an extensive project plan
with emails and data gathering and anything else
that's needed to compile the information about what's
happening with security in your environment.
Before starting the gap analysis,
it's useful to have a baseline.
This gives you something to work towards
and an idea of where the goals should
be for your organization.
There are a number of different baselines to choose from,
and some of these baselines have been specifically created
for certain organizations.
For example, your organization may
be following a set of baselines from the National Institute
of Standards and Technologies.
They publish a document called the Special Publication 800-171
Revision 2.
And the title of that document is Protecting Controlled
Unclassified Information in Nonfederal Systems
and Organizations.
You might also use a baseline that
was created by the International Organization
for Standardization and the International Electrotechnical
Commission.
This is the ISO/IEC 27001, or the information security
management systems.
And of course, you can create your own baselines
based on your specific needs as an organization.
These baselines will commonly involve
an analysis of the people in your organization
and the processes you use for security.
When evaluating people, you might
want to get a better understanding
of their formal experience in information technology
security.
You might want to understand what kind of training
they've received.
And you might want to see if they
have a knowledge of specific security policies
and procedures that you can use in your organization.
Even with the right people in place,
you'll still want to be sure that you're
following the correct policies for IT security.
This might start with an evaluation of the existing IT
systems and how they relate to your formal policies that
have been created in your central security policy
documentation.
The analysis portion of the gap analysis
will begin with a comparison of the existing systems
that you have running in your environment
and to identify any weaknesses that those systems might have.
You can also compare these weaknesses
with the most effective processes
for understanding how to compensate
for those weaknesses.
Ultimately, you'll create a detailed analysis
where you'll look at very broad categories of security
and then break down those broad securities
into individual smaller segments.
Here's a good example of how you might
start with broad understanding of a process
and then breaking it down into individual pieces.
This is the document 800-171 Revision 2,
which is Protecting Controlled Unclassified Information.
And this is a table that maps the access control requirements
to the security controls that are in place.
For example, this page shows access control
where you would want to limit system
access to unauthorized users, processes
acting on behalf of authorized users, and devices.
This account management covers a number
of different individual security controls.
So when we start to break this down,
we can look at user registration and deregistration.
We need to understand how user access provisioning is handled,
understand the management of privileged access rights,
a review of the user access rights, and so on.
By looking at these broad areas, we
can now break down individual security tasks
to see how well we're handling the processes
and procedures for each of these individual steps.
Once we've gathered all of this information
for all of our processes, all of our devices
across all of our different locations,
we need to create a final document that
summarizes everything that we've discovered.
We can start with a comparison that
looks at the detailed baseline objectives
and gives a perspective of where we are today
versus where we would like to be with each
one of these objectives.
Perhaps the more difficult question to answer
is how you get from where you are to where you'd like to be.
This path to get from where we are
to where we'd like to be commonly
takes time, it takes money, there may be equipment
that we need to purchase, and, obviously,
there's change control so that you can implement these changes
in your environment.
Once we have all of this information compiled
and the plan of how we can get from where
we are to where we'd like to be, we
can create a final gap analysis report.
This report not only includes the information
about where we are today, but it also provides that pathway
so that we can understand what it's really
going to take to move forward into the future.
All of the recommendations you have
about meeting this baseline will be documented
in this gap analysis report.
Here's an example of one of the tables
that you might include in your gap analysis report.
On the left side, I have a series of system requirements.
And all of those system requirements
were broken into smaller pieces in the detailed part
of the report.
But we might want to get a much broader understanding
about all of our different remote sites
and how they are compared to the ultimate baseline
that we would like to reach.
For example, our organization might
have seven different locations, and we've
performed a gap analysis across all
of these system requirements for all seven of those locations.
The locations that are relatively
close to meeting the baseline we can mark with a green color.
Anything that might be in the midpoint we can mark as yellow.
And locations that need a lot of work
to be able to meet our standardized baselines we'll
mark with red.
So if we wanted to have the biggest impact on improving
our security, we may want to start with the locations
and security requirements marked in red,
and then move to the ones marked in yellow,
and then finally the green.
The report obviously will include extensive details
about why these colors were used and provide
a summary of how we can implement
security controls to better meet the goals of these baselines.
