ZugriffsmanagementPlattformen

Zugriffsmanagement, or access management, is the set of policies, processes, and technologies used to control who can access which resources within an information system. The aim is to grant the minimum level of access necessary for tasks while preventing unauthorized use, thereby protecting confidentiality, integrity, and availability of data and services.

Core components include identity management, authentication, authorization, and session management. Identity management covers the provisioning and de-provisioning of user accounts and devices. Authentication verifies that a user or service is who they claim to be, commonly through passwords, multi-factor authentication, or biometrics. Authorization determines what resources and actions a verified user may access, often implemented through access control models such as RBAC (role-based), ABAC (attribute-based), DAC (discretionary), or MAC (mandatory). Privileged Access Management (PAM) focuses on high-privilege accounts to minimize risk.

Processes governing Zugriffsmanagement include the user lifecycle, adherence to the principle of least privilege, and separation of duties. Regular access reviews and revocation of unused or compromised credentials are essential to maintain security. Technologies involved include identity providers, single sign-on, directory services, and cloud-based or on-premises IAM (identity and access management) platforms. Logging and auditing support incident response and compliance.

The importance of Zugriffsmanagement spans organizations, regulatory regimes, and cloud environments. Proper implementation reduces the risk of data breaches, supports governance and compliance (for example with GDPR, HIPAA, or SOX), and improves operational control. Challenges include misconfigurations, excessive permissions, stale accounts, and evolving user needs. Effective Zugriffsmanagement requires organizational alignment, ongoing governance, and regular assessments across on-premises and cloud resources.
