![]() It then uses traffic tags to enforce segmentation policy directly on the network equipment, yet without the complexity of traditional approaches. Today, software-defined access technology simplifies segmentation by grouping and tagging network traffic. However, these approaches are costly and difficult. Some traditional technologies for segmentation included internal firewalls, and Access Control List (ACL) and Virtual Local Area Network (VLAN) configurations on networking equipment. And by reducing overall network traffic, the financial system will work better for the financial analysts who use it.

The bank's security policy restricts branch employees from accessing its financial reporting system.
