## Network Perimeter Security

Network perimeter security is the collection of tools and policies designed to protect a network from unauthorized access and cyber threats. In the context of financial platforms, it involves securing the edge of the network where users interact with the application.

This includes firewalls, intrusion detection systems, and geofencing filters. The perimeter acts as the first line of defense against attacks and regulatory non-compliance.

By strictly controlling traffic entering the network, platforms can mitigate risks such as DDoS attacks or unauthorized jurisdictional access. As services move to the cloud and decentralized architectures, the traditional perimeter is becoming more fluid, leading to the adoption of zero-trust models.

Effective perimeter security is essential for maintaining the operational integrity of a platform. It requires constant monitoring and updates to defend against evolving threat vectors.
