Was ist Identitäts- und Zugriffsverwaltung?

Die Identitäts- und Zugriffsverwaltung (Identity and Access Management, IAM) steuert, wer in einem Unternehmen auf welche Systeme, Daten und Anwendungen zugreifen darf. Sie stellt sicher, dass nur berechtigte Personen Zugriff erhalten – und das zur richtigen Zeit und mit den passenden Rechten. IAM-Systeme erhöhen die Sicherheit und Compliance, indem sie Benutzerkonten zentral verwalten und Zugriffe automatisch kontrollieren. So lassen sich Risiken durch unbefugte Zugriffe deutlich reduzieren.

Was macht ein Identity and Access Manager?

Ein Identity and Access Manager ist für die Verwaltung und Kontrolle digitaler Identitäten im Unternehmen zuständig. Er sorgt dafür, dass Mitarbeiter, Partner und Systeme die richtigen Zugriffsrechte erhalten. Dazu gehören die Vergabe, Überwachung und regelmäßige Überprüfung von Berechtigungen. Außerdem arbeitet er eng mit der IT-Sicherheit zusammen, um Angriffe durch kompromittierte Konten zu verhindern. Der Beruf spielt eine Schlüsselrolle in der Cybersicherheit und Compliance.

Was bedeutet Access Management?

Access Management bezeichnet den Prozess der Steuerung und Überwachung von Zugriffsrechten auf Systeme, Daten und Anwendungen. Ziel ist es, sicherzustellen, dass nur autorisierte Benutzer Zugriff auf sensible Informationen haben. Dazu gehören Authentifizierung (z. B. Login oder Multi-Faktor-Verfahren) und Autorisierung (Zuweisung von Rechten). Ein effektives Access Management schützt vor Datenlecks und Cyberangriffen.

Was versteht man unter Identitätsmanagement?

Identitätsmanagement (Identity Management, IdM) bezieht sich auf die Verwaltung digitaler Identitäten und Benutzerkonten. Es umfasst die Erstellung, Aktualisierung und Löschung von Benutzerprofilen innerhalb eines Unternehmens. Durch automatisierte Prozesse wird sichergestellt, dass jeder Benutzer nur die Zugriffsrechte besitzt, die er tatsächlich benötigt. Identitätsmanagement bildet damit die Basis für Sicherheit, Transparenz und effizientes IT-Benutzermanagement.

Keep track of all permissions with Identity and Access Management

Effective Identity and Access Management (IAM) is essential for ensuring information security and compliance within an organisation. IAM ensures that only authorised individuals are granted access to critical systems and data – and only to the extent necessary for their tasks. This is based on the ‘principle of least privilege’. With Materna, you gain a partner with whom you can work together to implement the right standards and authorisation strategies.

Everything you need to know about identity and access management

Identity and Access Management (IAM) controls who in an organisation is permitted to access which systems, data and applications. It ensures that only authorised individuals are granted access – at the right time and with the appropriate permissions. IAM systems enhance security and compliance by centrally managing user accounts and automatically controlling access. This significantly reduces the risks associated with unauthorised access.

An Identity and Access Manager is responsible for managing and controlling digital identities within an organisation. They ensure that employees, partners and systems are granted the correct access rights. This includes assigning, monitoring and regularly reviewing permissions. They also work closely with the IT security team to prevent attacks via compromised accounts. The role plays a key part in cybersecurity and compliance.

Access management refers to the process of controlling and monitoring access rights to systems, data and applications. The aim is to ensure that only authorised users have access to sensitive information. This includes authentication (e.g. login or multi-factor authentication) and authorisation (the assignment of rights). Effective access management protects against data breaches and cyberattacks.

Identity management (IdM) refers to the management of digital identities and user accounts. It encompasses the creation, updating and deletion of user profiles within an organisation. Automated processes ensure that each user has only the access rights they actually require. Identity management thus forms the basis for security, transparency and efficient IT user management.

Why does your organisation need identity and access management?

Complex authorisation structures pose significant security risks. Access rights that have been granted once often remain in place permanently, even when they are no longer needed. Over time, employees accumulate unnecessary or excessive permissions, leading to dangerous over-privileging. The situation becomes particularly critical when user accounts of former employees remain active, allowing them to continue accessing sensitive company data. Such vulnerabilities significantly increase the attack surface – especially when outdated or compromised accounts with extensive rights are exploited.

A well-designed IAM system provides a solution by ensuring clear processes, workflows, transparency and a high level of security. It manages identities and roles centrally and uses automated processes to ensure the provisioning and deprovisioning of identities in the correct target systems. It ensures secure authentication and precise access control, and helps to meet regulatory requirements and compliance standards. At the same time, it increases the transparency and traceability of all access. Through precisely defined processes for onboarding, offboarding and role management, an IAM system boosts efficiency, reduces errors and minimises security risks.
