Systematic security governance is essential to minimize security risks and meet regulatory requirements.🛡️ Security architecture and concepts:• Developing a comprehensive security architecture with a defense-in-depth approach across all system levels (network, infrastructure, application, data)• Implementing a consistent identity and access management (IAM) system with role-based access control and the principle of least privilege• Establishing a secure system architecture with clear segmentation, defined security zones, and controlled transition points• Implementing a data classification framework with differentiated protective measures for different data sensitivity classes• Developing a consistent encryption strategy for data at rest, in transit, and during processing🔍 Security testing and validation:• Integrating security requirements engineering into the requirements process for all customizations and extensions• Conducting regular security audits and penetration tests with a particular focus on customer-specific customizations• Implementing a secure development lifecycle (SDLC) with integrated security checks at all development stages• Using automated security testing tools (SAST, DAST, SCA) for continuous checking for security vulnerabilities• Establishing regular security reviews for configuration settings and authorization structures🔄 Operational security management:• Implementing a systematic patch management process with clear responsibilities, prioritization, and schedules• Establishing a comprehensive logging and monitoring concept with a focus on security-relevant events and anomalous behavior• Developing and regularly reviewing incident response plans for various security incident scenarios• Implementing a systematic vulnerability management process for the continuous identification and remediation of vulnerabilities• Building a security operations center (SOC) or integrating into existing SOC structures for continuous security monitoring🏛️ Governance and compliance:• Integrating standard software security into the company-wide information security management system (ISMS)• Conducting regular compliance checks to verify adherence to internal security policies and external regulations• Developing clear security guidelines for the development, operation, and use of customized standard software• Establishing a continuous security awareness program for developers, administrators, and end users• Implementing a security risk assessment for all planned changes and extensions within the change management process

Question 20

What role do DevOps practices play in the continuous improvement of customized standard software?

Accepted Answer

DevOps practices can make a decisive contribution to the continuous improvement of customized standard software. They enable faster customization cycles, higher quality, and improved collaboration between development, operations, and business units.🔄 Continuous integration and delivery:• Setting up automated build and deployment pipelines for customer-specific extensions and configuration changes• Implementing infrastructure as code (IaC) for automated provisioning and configuration of development, test, and production environments• Establishing a systematic versioning concept for all configurations, customizations, and customer-specific developments• Using containerization and orchestration for consistent environments throughout the entire lifecycle• Implementing feature flags for controlled activation of new functionalities and A/B testing capabilities🧪 Quality assurance and testing:• Integrating automated tests into the CI/CD pipeline with a particular focus on customer-specific customizations• Implementing various test levels (unit, integration, system, acceptance tests) for comprehensive quality assurance• Developing test automation frameworks for efficient creation and execution of automated tests• Establishing continuous code quality analyses with defined quality metrics and threshold values• Implementing chaos engineering for proactive identification of stability issues📊 Monitoring and feedback:• Building a comprehensive monitoring system with business-level KPIs, technical metrics, and user experience indicators• Implementing real user monitoring for direct capture of actual user experience• Establishing a feedback culture with short feedback loops and direct communication channels between users and development teams• Using application performance monitoring for detailed insights into runtime behavior• Setting up dashboards and alerting systems for real-time transparency and proactive problem detection👥 Collaboration and culture:• Promoting a collaborative culture between business, development, and operations with shared responsibility for software quality• Establishing cross-functional teams with end-to-end responsibility for defined functional areas• Implementing agile methods such as Scrum or Kanban for iterative improvement and continuous value creation• Conducting regular retrospectives for continuous process improvement at team and organizational level• Promoting an error culture in which mistakes are viewed as learning opportunities and communicated openly
