Intuitive GUI Helps Yahoo Japan Make Quick Changes to Monitoring Filters and Improve Network Visibility

Yahoo Japan Corporation is one of the largest providers of Internet services (including search engine, online shopping, auction, and news) in Japan. Its services are supported by hundreds of thousands of physical and virtual servers running in several data centers located in Japan and overseas. This massive computer network is exposed to cyber-attacks on a daily basis. To keep track of and analyze the incoming attacks in detail using IPS (Intrusion Prevention System), the company opted to use Keysight’s network packet broker (NPB), a portfolio of network visibility solutions featuring an intuitive GUI.

Aggregate The Massive Traffic And Pass Only The Required Data  to the LPS

Being Japan’s largest provider of Internet services means being subject to the most cyber-attacks in the country. According to Mr. Yusuke Tatsumi (Network Security, Infrastructure Engineering Department, Site Operation Division), in charge of Yahoo Japan Corporation’s security operations, “Security vendors would be shocked by the sheer volume of the cyber-attacks we receive.”

As a result, the company wanted to develop a strong infrastructure that could remain unaffected by such massive cyber-attacks. At the same time, it wanted to establish a system to visualize the source and nature of the incoming attacks and respond to them quickly.

“We strive to provide our in-house engineers, with an environment that allows them to concentrate on developing new services without being distracted by cumbersome. things like IP addresses and network security,” said Mr. Ryutaro Inoue (Manager, Network Security, Site Operation Division, System Management Group, Yahoo Japan Corporation).

The first step was identifying the enemy. “As part of our efforts to enhance network security, we wanted to keep track of the different types of incoming cyber-attacks and respond to them on a routine basis. Previously, IP addresses were just about the only information we had available on the attacks. We therefore wanted to implement security  devices such as IDS (Intrusion Detection System) and WAF (Web Application Firewall) to be able to keep track of the attacks in greater detail,” Mr. Inoue said.

Given the scale of Yahoo Japan Corporation’s network activity, it is impossible to monitor such massive traffic without a visualization solution that enables them to extract only the required traffic from the enormous data received by the network devices and aggregate and pass them on to the monitoring tool Yahoo Japan Corporation set its eyes on Keysight’s NPB solution—a portfolio of network visibility solutions developed by Keysight.

Flexible Data Manipulation Via Intuitive GUI Plays A Key Factor Behind  Product Adoption

Adoption of the Keysight Vision series has enabled the company to establish a system that aggregates and extracts only the data matching specified criteria and passes it to the security device for detailed analysis and appropriate countermeasures.
