AWS re:Invent 2023 - Secure access to AWS with ZTNA 2.0 (HYB204)

Summary

Don Meyer from Palo Alto Networks discusses the evolution of cybersecurity, focusing on Zero Trust Network Access (ZTNA) and its latest iteration, ZTNA 2.0.
ZTNA 2.0 is presented as a solution to the challenges of remote and hybrid workforces, securing access to applications and data in AWS and other environments.
The traditional VPN and MPLS approaches are deemed inadequate for modern infrastructure, as they do not align with the shift of users and data outside the network perimeter.
ZTNA 1.0 was a step forward but had limitations, such as only validating users at a single point in time and not providing continuous trust verification.
ZTNA 2.0 addresses these issues by offering continuous trust verification, keeping private apps private, and providing continuous security inspection for every session and application.
Palo Alto Networks' Prisma Access product, which runs on AWS, is highlighted as a cloud-delivered security platform that embodies ZTNA 2.0 principles.
The talk emphasizes the importance of AI in enhancing security measures, with examples of how Palo Alto Networks uses AI to combat threats and improve security operations.
The session concludes with a call to align security capabilities with business outcomes and to ensure optimal user experience without compromising security.

The shift to remote and hybrid workforces has significantly increased the attack surface for organizations, necessitating a reevaluation of traditional security models.
ZTNA 2.0 is positioned as a more dynamic and adaptive security model compared to ZTNA 1.0, with continuous verification and inspection capabilities that align with the principle of least privilege.
The integration of AI and machine learning into cybersecurity tools is crucial for staying ahead of rapidly evolving threats and reducing the burden on security operations.
The speaker highlights the importance of DNS security, IoT policy management, and data loss prevention (DLP) in the context of a comprehensive security strategy.
The reliance on AWS infrastructure for delivering Prisma Access and other security services underscores the trend towards cloud-based security solutions that can scale with organizational needs and provide high performance.
The talk suggests that security should not be an afterthought but an enabler of business objectives, with the right policies and tools in place to support the way people work and interact with technology today.
