Description: An access control system is a technological solution that manages and enforces access control policies to resources and data, ensuring that only authorized users can access sensitive information or restricted areas. This system is based on the identification, authentication, and authorization of users, allowing for a granular approach to permission management. In the context of Zero Trust security, it is assumed that no entity, whether internal or external, is trusted by default, meaning that every access must be verified. Network segmentation is another key feature, as it allows dividing the network into smaller segments to limit access and minimize the risk of security breaches. Additionally, these systems are fundamental for data privacy and protection, ensuring that personal and sensitive information is safeguarded against unauthorized access. In various environments, zero trust becomes an essential principle, as data may reside in multiple locations and be accessible from various devices. Identity and access management (IAM) is crucial for implementing an effective access control system, as it allows for managing who has access to what resources. Finally, embedded systems can integrate these access control solutions into physical devices, enhancing security in industrial and commercial environments.
