Chapter Review

• Central to securing systems is understanding their component interactions and architectures.
• Architectural terminology overlaps, but each approach provides unique challenges.
• Client-based systems run all core functions on the user's device, requiring no network.
• Server-based systems need clients to request services from servers across a network.
• Transactions are actions changing database states.
• ACID properties (Atomicity, Consistency, Isolation, Durability) are crucial for database transactions.
• Aggregation combines information from multiple sources.
• Inference deduces sensitive information from aggregated data.
• High-performance computing (HPC) aggregates computing power for large problems.
• Industrial control systems (ICS) control physical devices in industrial processes.
• Cyber-physical systems involve computer-physical device collaboration.
• Distributed control systems (DCS) and supervisory control and data acquisition (SCADA) are two main ICS types.
• DCS controls local processes, while SCADA controls remote processes.
• ICS must be logically or physically isolated from public networks.
• Virtualized systems operate in simulated environments.
• Virtual machines (VMs) are systems where computer hardware is virtualized for OS use.

System Architectures

• Containers house operating systems for applications.
• Microservices divide features into independent components.
• Serverless architectures don't need dedicated servers for services.
• Cloud computing uses remote devices for efficiency, performance, reliability, scalability, and security.
• SaaS provides access to specific applications in cloud environments.
• PaaS offers a computing platform, but not the OS or VM.
• IaaS provides full control over cloud devices, including OS and VM.
• Embedded systems are self-contained with specific purposes.
• Internet of Things (IoT) is a global network of connected systems.
• Distributed systems use interconnected nodes for collective tasks.
• Edge computing performs tasks near data sources to reduce latency.

Questions (Conceptual Understanding)

• Database transactions are evaluated based on properties like atomicity and isolation.
