A security incident handling process is a set of procedures and activities that aim to identify, analyze, contain, eradicate, recover from, and learn from security incidents that affect the confidentiality, integrity, or availability of information assets12.

The maturity of a security incident handling process is the degree to which the process is defined, managed, measured, controlled, and improved, and the extent to which it meets the organization’s objectives and expectations34.

The best key performance indicator (KPI) to measure the maturity of a security incident handling process is the number of recurring security incidents, which is the frequency or rate of security incidents that are repeated or reoccur after being resolved or closed56.

The number of recurring security incidents is the best KPI because it reflects the effectiveness and efficiency of the security incident handling process, and the ability of the process to prevent or reduce the recurrence of security incidents through root cause analysis, corrective actions, and continuous improvement56.

The number of recurring security incidents is also the best KPI because it is directly related to the organization’s objectives and expectations, such as minimizing the impact and cost of security incidents, enhancing the security posture and resilience of the organization, and complying with the relevant standards and regulations56.

The other options are not the best KPIs, but rather possible metrics that may support or complement the measurement of the maturity of the security incident handling process. For example:

The number of security incidents escalated to senior management is a metric that indicates the severity or complexity of security incidents, and the involvement or awareness of the seniormanagement in the security incident handling process56. However, this metric doesnot measure the effectiveness or efficiency of the process, or the ability of the process to prevent or reduce security incidents56.

The number of resolved security incidents is a metric that indicates the output or outcome of the security incident handling process, and the performance or productivity of the security incident handling team56. However, this metric does not measure the quality or sustainability of the resolution, or the ability of the process to prevent or reduce security incidents56.

The number of newly identified security incidents is a metric that indicates the input or demand of the security incident handling process, and the capability or capacity of the security incident detection and identification mechanisms56. However, this metric does not measure the effectiveness or efficiency of the process, or the ability of the process to prevent or reduce security incidents56. References =

The risk of terminated employee accounts maintaining access is that the former employees or unauthorized parties may use the accounts to access or manipulate the organization’s information systems or resources, and cause harm or damage to the organization and its stakeholders, such as data loss, data breach, system failure, fraud, etc.

The first step to address the risk of terminated employee accounts maintaining access is to disable user access, which means to revoke or remove the permissions or privileges that allow the accounts to access or use the organization’s information systems or resources. Disabling user access can help the organization to address the risk by providing the following benefits:

It can prevent or stop the former employees or unauthorized parties from accessing or using the organization’s information systems or resources, and reduce or eliminate the potential harm or damage that they may cause for the organization and its stakeholders.

It can ensure the confidentiality, integrity, availability, and reliability of the organization’s information systems or resources, and protect them from unauthorized access or manipulation.

It can provide useful evidence and records for the verification and validation of the organization’s access control function, and for the compliance with the organization’s access control policies and standards.

The other options are not the first steps to address the risk of terminated employee accounts maintaining access, because they do not provide the same level of urgency and effectiveness that disabling user access provides, and they may not be sufficient or appropriate to address the risk.

Performing a risk assessment is a process of measuring and comparing the likelihood and impact of various risk scenarios, and prioritizing them based on their significance and urgency.Performing a risk assessment can help the organization to understand and document the risk of terminated employee accounts maintaining access, but it is not the first step to address the risk, because it does not prevent or stop the former employees or unauthorized parties from accessing or using the organization’s information systems or resources, and it may not be timely or feasible to perform a risk assessment before disabling user access.

Developing an access control policy is a process of defining and describing the rules or guidelines that specify the expectations and requirements for the organization’s access control function, such as who can access what, when, how, and why. Developing an access control policy can help the organization to establish and communicate the boundaries and objectives for the organization’s access control function, but it is not the first step to address the risk, because it does not prevent or stop the former employees or unauthorized parties from accessing or using the organization’s information systems or resources, and it may not be relevant or applicable to the existing or emerging risk scenarios that may affect the organization’s access control function.

Performing a root cause analysis is a process of identifying and understanding the underlying or fundamental causes or factors that contribute to or result in a problem or incident that has occurred or may occur in the organization. Performing a root cause analysis can help the organization to address and correct the risk of terminated employee accounts maintaining access, and prevent or reduce its recurrence or impact, but it is not the first step to address the risk, because it does not prevent or stop the former employees or unauthorized parties from accessing or using the organization’s information systems or resources, and it may not be timely or feasible to perform a root cause analysis before disabling user access. References =

Key risk indicators (KRIs) are metrics used by organizations to monitor and assess potential risks that may impact their objectives and performance. KRIs also provide early warning signals that help organizations identify, analyze, and address risks before they escalate into significant issues1. The most importantreason to monitor KRIs is to help management lessen the impact of realized risk, which is the actual or expected negative consequence of a risk event2. By monitoring KRIs, management can gain insight into the current and emerging risk exposures and trends, and evaluate their alignment with the organization’s risk appetite and tolerance3. This enables management to make informed and timely decisions and actions to mitigate or eliminate the risks, and to allocate resources and prioritize efforts where they are most needed. By lessening the impact of realized risk, management can also protect and enhance the organization’s reputation, performance, and value. Identifying early risk transfer strategies, analyzing the chain of risk events, and identifying the root cause of risk events are not the most important reasons to monitor KRIs, as they do not provide the same level of benefit and value as lessening the impact of realized risk. Identifying early risk transfer strategies is a process that involves finding and implementing ways to shift or share the risk or its impact to another party, such as through insurance, outsourcing, or hedging4. Identifying early risk transfer strategies can help to reduce the organization’s risk exposure and liability, but it does not necessarily lessen the impact of realized risk, as the risk or its impact may still occur or affect the organization indirectly. Analyzing the chain of risk events is a process that involves tracing and understanding the sequence and interconnection of the risk events that lead to a specific outcome or consequence5. Analyzing the chain of risk events can help to identify and address the root causes and contributing factors of the risk events, but it does not necessarily lessen the impact of realized risk, as the outcome or consequence may have already occurred or be unavoidable. Identifying the root cause of risk events is a process that involves finding and determining the underlying or fundamental source or reason of the risk events. Identifying the root cause of risk events can help to prevent or correct the recurrence or escalation of the risk events, but it does not necessarily lessen the impact of realized risk, as the impact may have already happened or be irreversible. References = 1: Key Risk Indicators: A Practical Guide | SafetyCulture2: Risk Impact - an overview | ScienceDirect Topics3: KRI Framework for Operational Risk Management | Workiva4: Risk Transfer - an overview | ScienceDirect Topics5: EventChainMethodology - Wikipedia : [Root Cause Analysis - an overview | ScienceDirect Topics] : [Risk and Information Systems Control Study Manual, Chapter 4: Risk and Control Monitoring and Reporting, Section 4.1: Key Risk Indicators, pp. 181-185.]

The control owner is the person who is responsible for ensuring that the control is designed to effectively address risk. The control owner is also responsible for implementing, operating, monitoring, and maintaining the control. The control owner should ensure that the control is aligned with the risk owner’s risk appetite and tolerance, and that the control is periodically reviewed and updated to reflect changes in the risk environment. The risk manager, the control tester, and the risk owner are not directly responsible for the design of the control, although they may provide input, feedback, or approval. References = Risk and Information Systems Control Study Manual, Chapter 1, Section 1.3.2, page 1-15.
