Identity Management and Access Management are on their way into the first line of defence when it comes to enterprise security. With changing architecture paradigms and with the identity of people, things and services being at the core of upcoming security concepts, maintaining identity and Access Governance is getting more and more a key discipline of IT security. This is true for traditional Access Governance within the enterprise and this will become even more true for the digital business and the identities of customers, consumers, partners and devices.
Many organizations have already established Access Governance processes as a toolset for achieving compliance with regulatory requirements and for mitigating access-related risks on a regular basis. Identity and Access Management(IAM) processes accompany every identity through its complete life cycle within an organisation: The management of corporate identities and their access to resources is the combination of both IAM technology and the application of well-defined processes and policies. Traditional ways of adding Access Governance to these processes include the implementation of well-defined access request and approval workflows, the scheduled execution of recertification programs and the analysis of assigned access rights for the violation of the Segregation of Duties (SoD) requirements.
While the initial cause for creating such a program is typically the need for being compliant to regulatory requirements, mature organisations realize that fulfilling such requirements is also a business need and fundamental general benefit. The design and implementation of a well-thought-out dynamic, efficient, flexible and swift identity and access management is the foundation layer for an efficient and proactive Access Governance system.
This requires appropriate concepts for both management processes and entitlement concepts: Lean and efficient roles lead to simplified assignment rules. Intelligent approval processes, including pre-approvals as the default for many entitlements reduce manual approval work and allow for easier certification. Embedding business know-how within the actual entitlement definition allows for the specification of more and more processes in a way that they do no longer require any administrative or business interaction.
Aiming at defining and implementing automatable access assignment and revocation processes in fact reduces the need for various Access Governance processes. Once the processes are designed in a manner that they prevent the assignment of undesirable entitlements to identities and that they make sure that entitlements no longer needed are revoked from identities, they make many checks and controls obsolete. On the other hand, the immediate and automated assignment of entitlements whenever required fulfil business requirements in making people effective and efficient from day one. Subsequent business process changes and thus changes in job descriptions and their required access rights can be propagated automatically without further manual steps.
Applying risk assessments to each individual entitlement is a crucial prerequisite when it comes to analysing assigned access. Once all access is understood regarding its criticality, a risk orientated approach towards recertification (i.e. high-risk entitlements more often and faster) can be chosen and by default time-based assignments of critical entitlements can be enforced.
Well-defined access management and Identity Management life cycle processes can help to ease the burden of the actual Access Governance exercises. Before looking into further, often costly and tedious measures, redesigning and rethinking assignment and revocation processes in an intelligent manner within a lean entitlement model might help in improving efficiency and gaining security.
