Auktorisoinnit

Auktorisoinnit, in the context of information security and system access, refers to the process of verifying the identity of a user or entity and granting them appropriate permissions to access resources. This is a fundamental concept in ensuring that only authorized individuals can perform specific actions or view sensitive data within a computer system or network. The process typically involves two key stages: authentication and authorization.

Authentication is the act of confirming that a user is who they claim to be. This is often achieved through credentials such as usernames and passwords, multi-factor authentication (MFA) methods like one-time codes or biometrics, or digital certificates. Once a user's identity has been successfully authenticated, the system then proceeds to authorization.

Authorization determines what actions the authenticated user is permitted to perform. This is based on predefined roles, access control lists (ACLs), or policies that dictate the level of access granted. For example, a standard user might be authorized to read files, while an administrator would have authorization to modify or delete them. Implementing robust auktorisoinnit is crucial for maintaining data integrity, confidentiality, and preventing unauthorized access that could lead to security breaches or operational disruptions.
