Title: Alejandro Naser Pastoriza: Innovator in Access Control Analysis

Introduction

Alejandro Naser Pastoriza is a notable inventor based in Madrid, Spain. He has made significant contributions to the field of access control analysis, with a focus on methods and systems that enhance security in provider networks. With a total of 2 patents, his work is recognized for its innovative approach to role reachability and access control policies.

Latest Patents

Pastoriza's latest patents include "Analysis of role reachability with transitive tags" and "Analysis of role reachability using policy complements." The first patent discloses methods, systems, and computer-readable media that allow an access control analyzer to determine a graph comprising nodes and edges. These nodes represent roles in a provider network, which are associated with access control policies that grant or deny access to resources based on key-value attributes. The analyzer assesses whether a first role can assume a second role through role assumption steps, considering transitive attributes that persist during these steps. The second patent focuses on analyzing role reachability using policy complements, where the access control analyzer evaluates two nodes in a graph to determine if a first role can assume a second role based on specific key-value tags.

Career Highlights

Alejandro Naser Pastoriza is currently employed at Amazon Technologies, Inc., where he continues to develop innovative solutions in access control. His work has been instrumental in enhancing the security measures within complex provider networks.
