Hello, Please I already have a private cloud environment built on 3 physical servers based on Openstack (Juno). I want to know how to implement an access control model (Attribute Based Access Control (ABAC)) to control the cloud resources, for example a database on the cloud. I mean, am I have to creat an instance for the access control model? or I have to use another physical machine for the access control, ......... or others?

Any helpful answer will be appreciated.

Hi,

You need to find an ABAC (attribute based access control) implementation. One such implementation is XACML, the eXtensible Access Control Markup Language. XACML, as you might know, defines:

  • an http://developers.axiomatics.com/blog/index/entry/xacml-reference-architecture.html (architecture)
  • a policy language, and
  • a request/response scheme.

In your case, you have a cloud environment. The deployment form factor (cloud vs. on prem) doesn't really matter so much. What matters is what you want to protect. You mention databases. What kind are they? Do you also have APIs? If you do, products like Away API Gateway could do the trick.

The company I work for (disclaimer) has a database-focused ABAC solution called http://www.axiomatics.com (Axiomatics) Data Access Filter (ADAF). It could solve your problems.

You can also check out the following resources:
