  1. Migrating authorization logic from an old system to a new one can take a long time and requires careful planning to avoid errors.
  2. Each part of a business can manage its own authorization rules, making it easier for them to control access based on their specific needs.
  3. As systems grow, it's important to keep improving and adapting to new challenges, like optimizing runtime decisions and better analyzing access logs.

  1. Fine-Grained Authorization (FGA) is a better way to manage user permissions in a system. It allows specific users to have certain actions on specific resources, making access control simpler and more organized.
  2. Relationship-Based Access Control (ReBAC) focuses on the connections between users and resources instead of just roles. It builds a graph to show these relationships, but it can be complicated and difficult to maintain.
  3. Attribute-Based Access Control (ABAC) uses attributes of users and resources to determine access, making it flexible and easier to implement. It allows for clear policy definitions without needing to change how users interact with the system.

  1. Authorization is a crucial part of managing digital evidence, and it needs to be efficient to handle many users and lots of data. Complex systems can find it hard to keep permissions clear.
  2. Current access control models like Role-Based Access Control (RBAC) and Discretionary Access Control (DAC) can get too complicated when managing many users and permissions. This can lead to messy code and performance issues.
  3. As organizations grow, they must decide how to structure their authorization logic, whether to centralize it in one team or spread it across many. Both choices have their own challenges in consistency and maintenance.

  1. A Domain-Specific Language (DSL) helps create clear and precise authorization policies for microservices. It makes it easier for everyone involved, from developers to managers, to understand authorization rules.
  2. The new policy language is designed to overcome performance issues by allowing lazy loading and efficient management of large datasets. This means it doesn't grab unnecessary data upfront, speeding up processes.
  3. Using YAML instead of complex formats makes the policies more readable and easier for non-engineers to understand. This helps ensure that more people can participate in and review authorization rules effectively.

  1. Global Incremental IDs are important for preventing ID collisions in distributed systems, especially during tasks like data backup and event ordering.
  2. UUID and Snowflake ID are two common types of global IDs, each with unique advantages and disadvantages. For instance, UUIDs are larger but widely used, while Snowflake IDs are smaller but more complex to generate.
  3. Different systems, like Sonyflake and Tinyid, offer specialized methods for generating IDs, helping to ensure performance and avoiding database bottlenecks.

  1. Building a solid authorization system in microservices is tough since there aren’t clear guidelines. It's vital to share experiences for better solutions.
  2. Managing permissions can get complicated as a business grows. A better approach is needed to handle access control efficiently.
  3. Security is critical in public safety products, and proper access management helps maintain trust and legal compliance.
