This document is a guide that outlines how a cloud-based Product Lifecycle Management (PLM) system enhances data security. It describes the collaborative efforts between Lectra's cloud operations team and Microsoft Azure in managing cloud security, ensuring that data is securely stored and protected from unauthorized access. The guide details three key aspects of data security: authentication mechanisms, data encryption, and secure access controls. It explains how multi-factor authentication and stringent access controls minimize the risk of breaches by ensuring that only authorized personnel can access critical data. Additionally, it highlights the role of advanced encryption techniques in safeguarding data during transit and storage, making sensitive information indecipherable to unauthorized entities. Finally, the document discusses how cloud-based identity and access management tools provide granular control over user permissions, further reducing the risk of insider threats. The overall aim is to demonstrate how adopting a cloud-based PLM can improve operational performance while enhancing security measures.
