Whenever it comes to danger, such environments reject static authorizations . A common problem "Break The Glass" is known as the act of breaking the static authorization in order to reach the required permission. Healthcare environment is full of different contexts and situations that require the authorizations to be dynamic. Dynamic Authorization is a concept of giving the choice to E-Health authorization system to choose the most suitable permission by considering one’s situation. This paper aims at preventing the matter of modifying the policy to make authorizations dynamic. It introduces a simple solution to provide Dynamic Authorization by orienting the authorization system decision using situations. Situations, which are calculated using Complex Event Processing, are integrated to XACML architecture. A Healthcare example proves the efficiency of our approach.

Policy based management aims at supporting dynamic adaptability of behavior by changing policy without recoding or stopping the system. The common accepted architecture of such systems includes two main management agents: the Policy Decision Point that analyses requests and set decisions based on a policy and the Policy Enforcement Point (PEP) that enforces the PDP’s decision. Modern access control policies include more and more obligations. As a consequence, PEPs must adapt dynamically to enforce them. We propose in this article a dynamically adaptable PEP compliant with XACMLv3 standard.

Mobility –roaming services in particular– during urgent situations exacerbate the access control issues. Dynamic authorization then is required. However, traditional access control fails to ensure policies to be dynamic. Instead, we propose to externalize the dynamic behavior management of networks and systems through situations. Situations modularize the policy into groups of rules and orient decisions. Our solution limits policy updates and hence authorization inconsistencies. The authorization system is built upon the XACML architecture coupled with a complex event- processing engine to handle the concept of situations. Situation- oriented attribute based policies are defined statically allowing static verification and validation.

A very common problem "Break The Glass" is known as the act of breaking the static authorization in order to reach the required permission. Health- care environment is full of different contexts and situations that require the authorizations to be dynamic. Dynamic Authorization is a concept of giving the choice to E-Health au- thorization system to choose the most suitable permission with considering one’s situation. This paper aims at preventing the matter of modifying the policy to make authorizations dynamic. It introduces a simple solution to provide Dynamic Authorization by orienting the authorization system decision using situations. Situations, which are calculated using Complex Event Processing, are integrated to XACML architecture. A Healthcare example proves the efficiency of our approach.
