Abstract:
Network perimeters are evolving.
With digital transformation blurring the lines between internal and external systems, the traditional assumption that “internal networks are inherently safe” no longer holds true. Modern infrastructures create complex environments where every connection can introduce potential risks — from segmentation gaps and compromised credentials to misconfigured access paths.

In this session, we’ll explore the current threat landscape around network access and analyze real-world attack scenarios. You’ll gain insights into why VPNs are increasingly targeted, how trust relationships between network segments can be misused, and where conventional security models face limitations in highly connected environments.

This isn’t just theory — we’ll share practical approaches to securing services and protecting sensitive data while maintaining usability. We’ll discuss strategies such as isolation techniques, micro-segmentation, and zero-trust-inspired access models that can strengthen your defenses against emerging threats.

If you rely on traditional segmentation alone, this session will give you new perspectives and tools to improve your security posture.
