Information security risk factors are the sources of uncertainty that may affect the confidentiality, integrity, or availability of information assets within an organization. Information security risk factors can include threats, vulnerabilities, or impacts that may compromise the security of information assets. Information security risk factors should be mitigated when developing in-house applications, which are software applications that are designed, developed, and maintained by the organization itself, rather than by external vendors or providers. Mitigating information security risk factors when developing in-house applications canhelp prevent or reduce the occurrence or consequences of security incidents, such as data breaches, cyberattacks, unauthorized access, or data loss. The best way to ensure that information security risk factors are mitigated when developing in-house applications is to identify information security controls in the requirements analysis. The requirements analysis is the stage of the system development life cycle (SDLC) where the business needs and expectations of the application are defined and documented. The requirements analysis should include the functional and non-functional requirements of the application, such as the features, functions, performance, quality, reliability, and security of the application. Identifying information security controls in the requirements analysis can help ensure that the security requirements of the application are clearly specified and agreed upon by the stakeholders, and that they are aligned with the organization’s security policies, standards, and regulations. Identifying information security controls in the requirements analysis can also help ensure that the security requirements are integrated into the design, development, testing, and deployment of the application, and that they are verified and validated throughout the SDLC. Identifying information security controls in the requirements analysis can also help ensure that the security requirements are traceable, measurable, and manageable, and that they can be monitored and reviewed for effectiveness and efficiency. References = THE SYSTEM DEVELOPMENT LIFE CYCLE (SDLC), p. 2-3, System Development Life Cycle - GeeksforGeeks, 7.3: Systems Development Life Cycle - Engineering LibreTexts, What Is SDLC? 7 Phases of System Development Life Cycle - Intetics.

 A control is a measure or action that is implemented to reduce the likelihood or impact of a risk event, or to enhance the benefits or opportunities of a risk event. A control owner is a person who is assigned the responsibility and authority for the design, implementation, operation, and maintenance of a control. The most appropriate person to be assigned ownership of a control is the individual accountable for monitoring control effectiveness, which is the process of measuring and evaluating the performance and compliance of the control. By assigning the control ownership to the individual accountable for monitoring control effectiveness, the organization can ensure that the control is aligned with the risk objectives, operates as intended, and delivers the expected results. References = 4

Continuous risk management process improvement is the practice of evaluating and enhancing the risk management process on a regular basis, to ensure that it is effective, efficient, and aligned with the business objectives and strategy. Continuous risk management processimprovement can help identify and address the gaps, weaknesses, or opportunities for improvement in the risk management process, and ensure that the process is responsive and adaptable to the changing risk environment. The most effective method for continuous risk management process improvement is periodic assessments, which are systematic and objective evaluations of the risk management process, performed at predefined intervals or after significant events. Periodic assessments can help measure and monitor the performance and maturity of the risk management process, using criteria such as the risk management framework, standards, policies, procedures, methods, tools, roles, responsibilities, and results. Periodic assessments can also help identify and analyze the strengths, weaknesses, threats, and opportunities of the risk management process, and provide feedback and recommendations for improvement. Periodic assessments can also help communicate and report the status and progress of the risk management process to the stakeholders, and obtain their input and support for improvement actions. References = Continuous Risk Management Guidebook, p. 7-8, ISO 31000: riskmanagement and its continuous improvement, How Continuous Monitoring Drives Risk Management.

Data encryption is the best method to protect organizational data within a production cloud environment, as it ensures the confidentiality, integrity, and availability of the data. Data encryption is the process oftransforming data into an unreadable format using a secret key or algorithm, so that only authorized parties can access and decrypt the data. Data encryption can protect data at rest (stored in the cloud) and data in transit (transferred over the network) from unauthorized access, modification, or deletion by malicious actors or accidental errors. Data encryption can also help organizations comply with legal, regulatory, and contractual requirements for data protection and privacy, such as GDPR, CCPA, and PCI DSS.
