Security hardening is the process of applying security configuration settings to systems and software to reduce their attack surface and improve their resistance to threats1. Security hardening settings are based on industry standards and best practices, such as the CIS Benchmarks2, which provide recommended security configurations for various software applications, operating systems, and network devices. However, security hardening settings may not always be compatible with the business requirements and objectives of an organization, and may negatively impact the functionality, performance, or usability of the systems and software3. Therefore, before applying any security hardening settings, an information security manager should perform a risk assessment to evaluate the potential benefits and drawbacks of the settings, and to identify and prioritize the risks associated with them. A risk assessment is a systematic process of identifying, analyzing, and evaluating the risks that an organization faces, and determining the appropriate risk responses. A risk assessment helps the information security manager to balance the security and business needs of the organization, and to communicate the risk level and impact to the relevant stakeholders. A risk assessment should be performed first, before taking any other actions, such as reducing security hardening settings, informing business management of the risk, or documenting a security exception, because it provides the necessary information and justification for making informed and rational decisions. References = 1: Basics of the CIS Hardening Guidelines | RSI Security 2: CIS Baseline Hardening and Security Configuration Guide | CalCom 3: CISM Review Manual 15th Edition, page 121 : CISM Review Manual 15th Edition, page 122 : CISM Review Manual 15th Edition, page 145 : CISM Review Manual 15th Edition, page 146 : CISM Review Manual 15th Edition, page 147

= According to the CISM Review Manual, the information security manager should actively engage with stakeholders to align security and business goals. This means understanding the business needs, expectations, and risk appetite of the stakeholders, and communicating the value and benefits of security initiatives to them. By engaging with stakeholders, the information security manager can also gain their support and commitment for security programs and projects, and ensure that security objectives are aligned with business strategy and priorities. References = CISM Review Manual, 16th Edition, ISACA, 2020, page 23.

The best thing to include in a business case when the return on investment (ROI) for an information security initiative is difficult to calculate is an estimated reduction in risk. Risk reduction is the expected benefit of implementing an information security initiative, as it reduces the likelihood and impact of threats and vulnerabilities that may affect the organization’s information assets and systems. By estimating the reduction in risk, the information security manager can demonstrate the value and benefits of the information security initiative to the organization’s performance, reputation, and competitiveness. The information security manager can also compare the estimated reduction in risk with the estimated cost of the information security initiative to determine its cost-effectiveness and feasibility. The other options are not the best thing to include in a business case, although they may be some inputs or outputs of the risk assessment process. A projected increase in maturity level is a potential outcome of implementing an information security initiative, as it improves the organization’s capabilities and processes for managing information security risks. However, it does not necessarily reflect the actual reduction in risk or the ROI of the information security initiative. A projected cost over time is a component of calculating the ROI of an information security initiative, as it reflects the total cost of ownership and maintenance of the initiative. However, it does not indicate the expected benefit or value of the initiative. An estimated increase in efficiency is a possible benefit of implementing an information security initiative, as it may enhance the organization’s productivity and performance. However, it may not be directly related to the reduction in risk or the ROI of the information security initiative.
