BWL - Informationswissenschaften, Informationsmanagement

Risk assessments play a critical role in the development and implementation of effective information security programs and help address a range of security related issues from advanced persistent threats to supply chain concerns.
The results of risk assessments are used to develop specific courses of action that can provide effective response measures to the identified risks as part of a broad-based risk management process.
The guidance provided here uses the key risk factors of threats, vulnerabilities, impact to missions and business operations, and the likelihood of threat exploitation of weaknesses in information systems and environments of operation, to help senior leaders and executives understand and assess the current information security risks to information technology infrastructure.

Objectives and Key Themes

This document aims to provide a practical and comprehensive methodology for conducting information technology risk assessments. The focus is on developing a best practice approach that can be implemented by organizations of all sizes.
• Implementing a best practice risk assessment methodology.
• Addressing the importance of information security programs and their role in managing risks.
• Developing effective response measures to identified risks through a risk management process.
• Understanding and assessing information security risks to information technology infrastructure.
• Providing guidance that is flexible and adaptable to various organizational needs.

Chapter Summaries

The document starts by outlining the importance of information security programs and risk assessments within a broader risk management framework. This involves defining key risk factors like threats, vulnerabilities, impacts, and likelihood of exploitation. The authors then detail the various risk assessment models and approaches available, covering both quantitative and qualitative techniques. The chapter further delves into different risk analysis strategies, such as threat-oriented, asset-oriented, and vulnerability-oriented approaches.

The document progresses by outlining the steps involved in preparing for a risk assessment. This includes defining the purpose, scope, assumptions, identifying information sources, and clarifying roles and responsibilities. The final chapter delves into the practical steps of conducting a risk assessment. This involves collecting information, identifying systems or processes at risk, evaluating the likelihood of harm occurring, assessing the impact, determining the risk for the item, and investigating options for control measures. The chapter concludes by emphasizing the need to prioritize actions, implement controls, and measure the effectiveness of these actions.
