Policies define how the users interact with the different systems and applications.

Most identity and access management (IAM) products provide a variety of methods for implementing the policies to control access to organizational resources, with varying terminology being used to describe these methods.

For example, an administrator can manually give another user access to an application at his or her discretion.

In fact, technically ABAC is capable of enforcing DAC, MAC, and RBAC.

Any available attribute in the directory can be used by itself or in combination with another to define the right filter for controlling access to a resource.

While RBAC and ABAC can be very complex subjects, here are four simple concepts you can refer to not only as you start your IAM implementation, but on an ongoing basis as your organization and needs change.

When you need more granularity than this or need to make a decisions under certain conditions, use ABAC.

For example, giving teachers access to Google if they are at School X and teach Grade Y.

The bigger and more complex the search, the more processing power and time it takes.

And, the more users and applications an organization has, the greater processing impact the searchesfilters will have because of the increase in search space.

A little bit of planning in advance can help you structure your directory data in a way that mitigates the need to develop complex filtersqueries.

However, every now and then, you will definitely have to get creative to establish the right level of access control, but this should be the exception and not the rule.

For example, using RBAC to control who can see what modules and then using ABAC to control access to what they see (or can do) inside of a module.

This is similar to a WAN and LAN-based firewalls where the WAN does the coarse-grain filtering and then LAN-based does the finer-grain inspections.

So, whether you use RBAC or ABAC, a good IAM solution should help you define what users can do with applications by providing multiple mechanisms to ensure the right people, get the right access, to the right thingsat the right time.
