In an increasing digitalized corporate world, where complex IT environments and high compliance requirements come together, the principle of Separation of Duties (SoD) is essential in the area of Identity Governance and Administration (IGA). SoD prevents a single person from being granted comprehensive access rights and thus protects against potential security risks. Without an effective SoD system, the risk increases considerably: companies face possible breaches of regulatory requirements, threats from insiders and serious security vulnerabilities. IGA tools such as NEXIS 4 offer a powerful solution to minimize these risks through structured access controls and strengthen compliance.
What is Separation of Duties (SoD) in context of IGA?
Separation of Duties (SoD) is a central principle in Identity Governance and Administration (IGA) and aims to minimize security risks by structuring and restricting access to critical systems and information. The main objective of SoD is to ensure that no single person has extensive rights that could give them exclusive control over sensitive data or systems. This significantly reduces the risk of misuse and insider threats. Key components of SoD include precise access controls that define who can access what information, as well as multi-level approval processes to ensure that access rights are traceable and fairly distributed. Another important aspect is the systemic separation of responsibilities, which ensures that different roles and system entitlements are clearly separated from one another. In this way, SoD supports secure or transparent access control and promotes reliable compliance.
Challenges in the implementation of SoD in complex IGA environments
The implementation of Separation of Duties (SoD) in Identity Governance and Administration (IGA) involves both technical and organizational challenges for companies. SoD requires a clear separation of access rights and roles, which is often difficult to implement in complex user structures or in companies with distributed systems. Especially in large organizations, managing different user roles and the associated permissions can quickly become confusing. SoD also supports risk management and facilitates compliance with European regulatory requirements, such as those required by the General Data Protection Regulation (GDPR) and the NIS 2 Directive. The clear separation and control of responsibilities reduces the risk of security gaps, which strengthens both data security and compliance. An effective SoD strategy thus protects companies from security breaches and helps them to meet regulatory standards.
How NEXIS 4 supports the implementation of SoD
NEXIS 4 offers comprehensive support for the implementation and management of Separation of Duties (SoD) in IGA environments and enables companies to manage even complex SoD requirements efficiently. A central feature is the mapping of an SoD matrix, which goes beyond the simple definition of individual policies. This matrix allows complex dependencies and exclusions between different roles and system entitlements to be clearly displayed. This is particularly important for companies that require not only individual SoD rules, but also comprehensive overviews to ensure secure and consistent access control. With the upcoming major release, NEXIS 4 will even offer a visual presentation of the SoD matrix, making the management of these policies even more intuitive.
An outstanding feature of NEXIS 4 is its ability to check SoD rules both *ex ante* and *ex post*. Thanks to the workflow-based live check, potential SoD violations can be detected and processed directly in the process. If a request encounters a combination of system entitlements that violates an SoD policy, NEXIS 4 can either block it or, if necessary, release it with a comment or documentation as a special approval. This enables flexible yet secure management of exceptions.
In addition, NEXIS 4 offers the possibility of *ex post* verification of SoD breaches by performing detective checks. This allows SoD violations to be detected after they have already occurred, allowing companies to analyze potential risks after the fact and take measures to improve security.
This combination of real-time checking and downstream analysis means that NEXIS 4 guarantees comprehensive control over SoD standards. Efficient system entitlement management, coupled with transparent audit functions, helps companies to continuously monitor and audit access rights. Automated processes facilitate the enforcement of SoD guidelines and offer full transparency in approval and monitoring processes. With NEXIS 4, companies can minimize security risks and at the same time ensure compliance requirements are met – and are therefore ideally positioned for future challenges.
Conclusion: The value of SoD in modern IGA with NEXIS 4
Separation of Duties (SoD) is a critical factor in protecting organizations from security risks and ensuring compliance requirements are met. With NEXIS 4, organizations can efficiently implement SoD policies by performing both preventive and retrospective checks and managing complex SoD matrices. The ability to integrate SoD conflicts directly into the workflow minimizes risks and creates transparency when dealing with exceptions. As a result, NEXIS 4 not only strengthens security, but also makes it easier to comply with regulatory requirements.
