In this detailed assignment, I created a robust security blueprint for "SnowBe Online," a fictitious lifestyle brand uniquely blending beach and snow interests. The company flourished with its roots in a laid-back culture, reaching impressive sales figures. My role was to ensure that their IT infrastructure, customer data, and transactional integrity remained secure as they expanded. The heart of the assignment was crafting three pivotal policies focused on the system development life cycle, software patch management, and security maturity. These policies were meticulously integrated into a broader security plan, which serves as a guiding document for the organization. The plan addresses vital aspects like identity management, PCI DSS compliance, change management, and physical security. With additional emphasis on roles, responsibilities, and adherence to standards and procedures, this document is crafted to protect the company's digital assets, ensuring confidentiality, availability, and data integrity.
