Description: Granular security is a security approach that allows detailed control over access and permissions in computer systems. This concept is based on the idea that instead of applying broad and generic security policies, specific rules can be established to regulate who can access what resources and under what conditions. This is especially relevant in complex environments like microservices, where multiple components interact with each other. Granular security enables organizations to define permissions at the user, application, or even function level, enhancing the protection of sensitive data and reducing the risk of unauthorized access. Additionally, in the context of DDoS (Distributed Denial of Service) protection, granular security can help identify and mitigate attacks by allowing more precise monitoring of traffic and implementing specific measures to block malicious requests without affecting the overall system performance. In summary, granular security is essential for maintaining the integrity and confidentiality of information in an increasingly complex and threatening digital world.
