1. Security Concepts

Case Study: Cloud Adoption and Security Strategy

A financial services firm is transitioning to the cloud but wants to focus solely on application development without managing infrastructure. They opt for Platform as a Service (PaaS), allowing them to streamline operations while maintaining security.

To secure their web servers, they implement a Defence in Depth strategy, layering security controls across physical, network and application levels. This ensures data integrity, a key principle of the CIA triad, preventing unauthorized alterations.

Faced with increasing regulatory requirements, the firm integrates Governance, Risk Compliance (GRC) into its security framework, ensuring compliance while mitigating threats.

Case Study: Implementing Zero Trust Security

A software company wants to adopt the Zero Trust security model to protect its resources. This means the IT team have a plan which is to:

• Verify all user and device identities
• Minimize user access scope
• Assume that any breach can happen

To enforce least privilege access, they grant users only the permissions needed for their current tasks, reducing the attack surface. Additionally, they implement risk-based conditional access policies, ensuring high-risk users must use multi-factor authentication (MFA) before accessing sensitive systems.

This proactive approach strengthens security, ensuring that no entity—internal or external—is automatically trusted without verification.

2. Identity and Access
