Learning Topic

Risk Management Process Risk management is an integral part of an organization's governance structure.

The figure below illustrates a generic risk management process that can be used to

manage risk at the organization level. This process is described in general terms in ISO

Standard 31000 and is used in the National Institute of Standards and Technology’s (NIST)

Special Publication 800-39 to describe the process of managing security risks associated

with information and information systems (NIST, 2011). This risk management process is

focused upon identifying and managing risks to the organization as a whole. The four

elements of this risk management process (frame, assess, respond, monitor) are discussed

in the sections that follow.

Risk framing is a business process that uses organizational context (problem frame) to

guide the identification and categorization of risks to assets. Risk framing categorizes risks

according to the type of asset, source of the risk to that asset (threat), and the

vulnerability of the asset to the threat. It is usually the first step in the risk management

process.

Risk sources are divided into two categories: opportunities and threats. The opportunity

category is primarily used to frame risks in project management risk analyses and financial

analyses (investment planning). Security risks are usually expressed in terms of threats to

assets and further categorized by the type of threat.

Risks may also be identified using information from published lists and databases of

known threats and vulnerabilities for specific products (hardware and software).

Authoritative vulnerability identification and description information can be obtained

from NIST, the Department of Defense (Defense Information Systems Agency), the

Department of Homeland Security (US-CERT), and the Mitre Corporation (a government

contractor).

Assess

Risk assessment is a business process used to evaluate and rank the risks identified in the

framing process. The output of the risk assessment process is a risk register containing

entries for individual risks and their associated risk impact metrics. Risk assessment may

be quantitative or qualitative. Quantitative risk assessments use statistical techniques to

analyze data from simulations, experiments, and threat models. Qualitative risk

assessments use expert opinion and judgment. Both types of assessment may use

historical information obtained from documents and reports.

Respond

Organizations use four types of risk response strategies:

acceptance

avoidance

transfer

mitigation

When a strategy is applied to a specific risk, it is referred to as a risk treatment.

We will discuss each of the four types of risk response strategies below.

Acceptance has two forms. For opportunity-based risks, an organization accepts the risk

in the expectation of a beneficial or profitable outcome. This form of acceptance usually

involves a deliberate action (e.g., signature on a memorandum) that authorizes the

acceptance of the risk. For threat-based risks, an organization accepts a risk when the

costs of taking action to prevent harm exceed the expected costs of doing nothing. This

form of acceptance may be either de facto (through no action) or de jure (formally

approved or agreed to by an oversight group).

Avoidance occurs when an organization makes a deliberate decision to avoid the

circumstances or situations in which a risk could arise. For example, after reviewing an

opportunity to invest in a new security technology, a venture capitalist could determine

that the potential payoff is too low when compared to other uses of the money and so

decides to not invest in the security technology. Not making the investment is an

avoidance strategy.

Transfer is accomplished by transferring responsibility for the outcome of the risk to

another organization. Two common types of transfer strategies are insurance and

outsourcing. Cyber insurance is purchased to protect an organization from financial losses

resulting from cyber attacks. Outsourcing transfers financial responsibility for specific

risks as part of a service-level agreement or other form of contract-for-services. Under US

law, ultimate responsibility for harm or loss to information and information systems

remains with the owners of those assets and cannot be transferred to an outside

organization.

Mitigation is the most complex of the four risk management strategies. This strategy

requires that organizations identify specific actions, processes, and technologies that can

be used to lessen the impact of a risk. Some mitigation measures focus upon reducing

vulnerabilities in assets (e.g., patching software) while others are used to lower the

probability of occurrence (e.g., deploying antivirus software to detect and block malware

before an infection occurs). Most security controls are intended as risk mitigation

measures.
