Principles of Organizational Design
• Strategic Alignment.
• Organization structure - Functional vs. Matrix
– Span of control – hierarchy
– Reporting relationship (governmance)
• Job descriptions
• Staffing and skill requirements (training)
• Grading (reward structure)
• Clarity about the boundaries with other organizational
groups

Information Security Planning
• Planning reduces the likelihood that the
organization will be reactionary toward the
security needs.
• Security planning involves developing security
policies and implementing controls to prevent
computer risks from becoming reality.
• The risk assessment provides a baseline for
implementing security plans to protect assets
against various threats.
Hierarchy of Security Planning
• Strategic Planning (3-5 years). Strategic plans are aligned
with the strategic business and IT goals. They provide the
vision for projects to achieve the business objectives. The
plans should be reviewed annually or whenever major
change to the business occur.
• Tactical Planning (6-18 months). Tactical plans provide
the broad initiatives to support and achieve the goals
specified in the strategic plans.
• Operational and Project Planning. Specific plans with
milestones, dates and accountabilities provide the
communication and direction to ensure that the individual
projects are completed.
Type of Security Planning
Proactive Planning:
• Develop security policies and controls.
• Implement tools and techniques to aid in security.
- Secure access, secure data, and secure code.
- Techniques for network security – firewall, VPN.
- Detection tools.
• Implement technologies to keep the system running
in the event of a failure.
Reactive Planning:
• Develop a contingency plan.
Examples of Security Plan

• Job rotation. Job rotation reduce the risk of collusion of
activities between individuals.
• Separation of duties. One individual should not have the
capability to execute all of the Steps of a particular process.
• Least privilege (need to know). Granting users only the
accesses that are required to perform their job functions.
• Mandatory vacations. Requiring mandatory vacations of a
specified consecutive-day period.
• Job position sensitivity. The access and duties of an individual
for a particular department should be assess to determine the
sensitivity of the position.
Separation of Duties
The same individual should not typically perform
the following functions:
•
•
•
•
•
•
•
•
•
Systems administration
Network management
Data entry
Computer operations
Security administration
Systems development and maintenance
