ArcSight Case Study: Chunghwa Telecom, Data Communications Business Group
| Summary: | The Chunghwa Telecom Data Communications Business Group (HiNet) operates as an ISP, delivering high quality managed services to over four million businesses across Taiwan. Providing a safe Internet experience is challenging, as the group receives 40+ million security events from ISP customer sites each day. |
| Business Challenge: | With an enormous volume of security information to sift through, it was very difficult and time-consuming to query historical events from all devices and networks, and nearly impossible to correlate one event source with another. Finding the root cause of any security issue was problematic - and not always possible. |
| Solutions: | ArcSight was the only vendor that met all of the HiNet criteria. ArcSight ESM protects its customer networks from external threats such as bots, worms and internal risks which include fraud and theft. ArcSight Logger unifies searching, reporting, alerting and analyzing across all of the different types of enterprise log data. |
| Benefits: |
Results of the ArcSight deployment have been impressive. "The ArcSight ETRM platform has enabled us to reduce the 40 million security events we receive each day down to just 45 critical events - that's about a million-to-one improvement ratio," says I-fang Wu, Deputy Managing Director, Data Communications Business Group, Chunghwa Telecom. With the ArcSight ETRM platform, HiNet can now accurately identify the root cause of any security event much more quickly. "The ArcSight ETRM platform greatly enhances the efficiency of our IT team," says Wu. |
