Defining Roles and Responsibilities
The establishment of clear roles and responsibilities is a critical success
factor for any risk management program due to the requirement for cross-group
interaction and segregated responsibilities. The following table describes the
primary roles and responsibilities used throughout the Microsoft security risk
management process.
Table 3.3 Primary Roles and Responsibilities in the
Microsoft Security Risk Management Process
| Title |
Primary Responsibility |
| Executive Sponsor |
Sponsors all activities associated with managing risk to
the business, for example, development, funding, authority, and support
for the Security Risk Management Team. This role is usually filled by an
executive such as the chief security officer or chief information
officer. This role also serves as the last escalation point to define
acceptable risk to the business. |
| Business Owner |
Is responsible for tangible and intangible assets to the
business. Business owners are also accountable for prioritizing business
assets and defining levels of impact to assets. Business owners are
usually accountable for defining acceptable risk levels; however, the
Executive Sponsor owns the final decision incorporating feedback from
the Information Security Group. |
| Information Security Group |
Owns the larger risk management process, including the
Assessing Risk and Measuring Program Effectiveness phases. Also defines
functional security requirements and measures IT controls and the
overall effectiveness of the security risk management program. |
| Information Technology Group |
Includes IT architecture, engineering, and operations. |
| Security Risk Management Team |
Responsible for driving the overall risk management
program. Also responsible for the Assessing Risk phase and prioritizing
risks to the business. At a minimum, the team is comprised of a
facilitator and note taker. |
| Risk Assessment Facilitator |
As lead role on the Security Risk Management Team,
conducts the data gathering discussions. This role may also lead the
entire risk management process. |
| Risk Assessment Note Taker |
Records detailed risk information during the data
gathering discussions. |
| Mitigation Owners |
Responsible for implementing and sustaining control
solutions to manage risk to an acceptable level. Includes the IT Group
and, in some cases, Business Owners. |
| Security Steering Committee |
Comprised of the Security Risk Management Team,
representatives from the IT Group, and specific Business Owners. The
Executive Sponsor usually chairs this committee. Responsible for
selecting mitigation strategies and defining acceptable risk for the
business. |
| Stakeholder |
General term referring to direct and indirect
participants in a given process or program; used throughout the
Microsoft security risk management process. Stakeholders may also
include groups outside IT, for example, finance, public relations, and
human resources. |
The Security Risk Management Team will encounter first-time participants in
the risk management process who may not fully understand their roles. Always
take the opportunity to provide an overview of the process and its participants.
The objective is to build consensus and highlight the fact that every
participant has ownership in managing risk. The following diagram, which
summarizes key participants and shows their high-level relationships, can be
helpful in communicating the previously-defined roles and responsibilities and
should provide an overview of the risk management program.
To summarize, the Executive Sponsor is ultimately accountable for defining
acceptable risk and provides guidance to the Security Risk Management Team in
terms of ranking risks to the business. The Security Risk Management Team is
responsible for assessing risk and defining functional requirements to mitigate
risk to an acceptable level. The Security Risk Management Team then collaborates
with the IT groups who own mitigation selection, implementation, and operations.
The final relationship defined below is the Security Risk Management Team's
oversight of measuring control effectiveness. This usually occurs in the form of
audit reports, which are also communicated to the Executive Sponsor.
