Hozzáférésengedélyezés

Hozzáférésengedélyezés, often translated as access authorization or permission granting, is a fundamental security concept in information technology. It refers to the process of determining whether a user, system, or process is allowed to access specific resources. This process typically involves verifying the identity of the entity requesting access and then checking if that identity has been granted the necessary privileges for the requested action on the target resource.

The core idea behind hozzáférésengedélyezés is to enforce security policies and protect sensitive data from unauthorized access or modification. It operates on the principle of least privilege, meaning entities should only be granted the minimum level of access required to perform their designated tasks. This minimizes the potential damage if an account or system is compromised.

Common mechanisms for implementing hozzáférésengedélyezés include role-based access control (RBAC), where permissions are assigned to roles, and users are then assigned to those roles. Access control lists (ACLs) are another method, which explicitly define permissions for individual users or groups on specific files or objects. The process of granting and revoking these permissions is crucial for maintaining ongoing security. Without proper hozzáférésengedélyezés, systems are vulnerable to data breaches, unauthorized changes, and denial-of-service attacks.
