East-West Traffic Control protects traffic data by monitoring, filtering, and securing communication between internal systems within a network, rather than just focusing on external (North-South) traffic. This is crucial because threats often originate from compromised internal devices or lateral movement within the network.
How it works:
Example: In a cloud environment, if a virtual machine (VM) is compromised, East-West Traffic Control can prevent the threat from spreading to other VMs in the same subnet by enforcing strict segmentation and inspecting traffic flows.
For cloud-based implementations, Tencent Cloud's Cloud Virtual Network (CVN) and Security Group features can help enforce East-West Traffic Control. Additionally, Tencent Cloud Network Security Solutions like DDoS Protection and Intrusion Detection Systems (IDS) enhance visibility and defense against internal threats.
