Modular Security

Definition ∞ Modular security pertains to a security architecture that divides complex systems into distinct, self-contained components or modules. Each module is designed with specific security functions and can be independently developed, tested, and updated. This approach allows for greater flexibility, maintainability, and the ability to swap out or enhance individual security elements without disrupting the entire system.
Context ∞ In the context of blockchain and decentralized systems, modular security is increasingly discussed concerning the development of scalable and secure infrastructure. Particular attention is paid to how different layers of a protocol, such as execution, settlement, and data availability, can each employ specialized security mechanisms. Ongoing research seeks to define best practices for inter-module communication security and to establish robust frameworks for auditing and verifying the integrity of each component.
