a single document, making its value seem almost worthless. However, since the
entire company is based on the recipe, losing this data could bankrupt the business.
For this reason, the importance of an asset must be considered.
Determining the importance of an asset is often speculative, and generally
involves assigning a weight (sometimes called a metric) to each asset.The weight of
the asset is based upon the impact a loss will have on the company. For example,
while a network router may have little monetary value, the loss of the router could
take out parts of the network, preventing people from doing their work.This makes
the weight of importance higher.When creating the inventory of assets, a column is
included on the sheet where a value can be assigned based upon the importance of
that equipment.This value is on a scale of 1 to 10, with 10 having the highest
importance.
The information gathered through asset identification can be used in priori-
tizing which assets should be dealt with first in an incident, and where policies and
procedures need to be created.As mentioned above, to calculate value, look at the
current depreciated value of the assets. Equipment and certain other assets of
importance are also used in other aspects of risk management, as will be seen in the
following sections.
TEST DAY TIP
Assets and risks may come not only in the form of objects, but also in
the form of people. Humans are also a resource, and may provide dis-
tinctive skill sets. They can also be the cause of major problems, such as
theft or malicious damage to equipment and data. When answering
questions dealing with risks and assets, do not forget that people are an
important component of both topics.
Risk Assessment
Although you have gathered a considerable amount of data to this point, you will
need to analyze this information to determine the probability of a risk occurring,
what is affected, and the costs involved with each risk.Assets have different risks
associated with them, and you need to correlate different risks with each of the
assets inventoried in a company. Some risks will impact all of the assets of a com-
pany, such as the risk of a massive fire destroying a building and everything in it,
while in other cases, groups of assets will be effected by specific risks.
