Access Control:

Access control is a way to manage who can access what resources in a system or facility. The primary methods of access control include:

1. Access Control: Access control is like setting up rules and permissions for who can access certain things, like entering a building or viewing files on a computer. It involves managing who can use or see specific resources, such as physical spaces, data, or digital systems. Access control systems enforce these rules to ensure only authorized individuals or systems can access the resources they need, keeping information secure and maintaining privacy.
2. Data Access Control: Data access control is a way of managing who can view, modify, or use specific pieces of data within a computer system or database. It involves setting up rules and permissions to restrict access to sensitive information and ensure that only authorized users or systems can access certain data.
3. System and Security Administration: System and security administration involves managing IT infrastructure, ensuring its smooth operation, implementing security measures to protect against threats, and maintaining data integrity and confidentiality.
4. System Design: System design involves planning and creating the architecture and structure of software or hardware systems to meet specific requirements and objectives. It encompasses defining components, relationships, and interactions to ensure efficient functionality and scalability while addressing user needs and technical constraints.
