한 조직이 최근 자체 회계 소프트웨어 시스템에 사용자 정의 코드를 배포하기 위해 애자일 모델로 전환했습니다. 프로덕션 코드 배포를 위한 절차를 검토할 때, 다음 중 가장 중요한 보안 문제는 무엇입니까?
정답: B
Change control is the process of managing and documenting changes to an information system or its components. Change control aims to ensure that changes are authorized, tested, approved, implemented, and reviewed in a controlled and consistent manner. Change control is an essential part of ensuring the security, reliability, and quality of an information system.
One of the key elements of change control is testing and approval from quality assurance (QA). QA is the function that verifies that the changes meet the requirements and specifications, comply with the standards and policies, and do not introduce any errors or vulnerabilities. QA testing and approval provide assurance that the changes are fit for purpose, function as expected, and do not compromise the security or performance of the system.
An organization that has recently moved to an agile model for deploying custom code to its in-house accounting software system should still follow change control procedures, including QA testing and approval.
Agile development methods emphasize flexibility, speed, and collaboration, but they do not eliminate the need for quality and security checks. In fact, agile methods can facilitate change control by enabling frequent and iterative testing and feedback throughout the development cycle.
However, if change control does not include testing and approval from QA, this poses a significant security concern for the organization. Without QA testing and approval, the changes may not be properly validated, verified, or evaluated before being deployed to production. This could result in introducing bugs, defects, or vulnerabilities that could affect the functionality, availability, integrity, or confidentiality of the accounting software system. For example, a change could cause data corruption, performance degradation, unauthorized access, or data leakage. These risks could have serious consequences for the organization's financial operations, compliance obligations, reputation, or legal liabilities.
Therefore, change control that does not include testing and approval from QA is the most significant security concern to address when reviewing the procedures in place for production code deployment in an agile model.
