Japan’s Online Banking Pioneer Gains Real-Time Visibility Into Cybersecurity Risks
The Japan Net Bank, Ltd. (JNB), Japan’s first internet-only bank, offers convenient, around-the-clock online banking services.
To follow the common practice in Japan’s financial services industry, JNB has joined the Financial Services Information Sharing and Analysis Center Japan (Financials ISAC Japan), a global financial industry resource for cyber and physical threat intelligence analysis and sharing. Since adopting Splunk Enterprise to derive real-time, actionable cybersecurity intelligence from operational data, JNB has seen the following benefits:
- Cyberattack management decreased from hours to minutes
- Prevention of illegal money transfers
- Identified opportunities for new security measures
Challenges
- Inefficient log management in the office automation environment
- Labor-intensive and time-consuming risk management processes
- Ineffective analysis of web access logs in detecting unauthorized accesses
Business Impact
- Accelerated analysis of cyberattacks from one-half to one day to a few minutes
- Prevented illegal money transfers
- Gained new opportunities for enhancing cybersecurity
Why Splunk
Unlike bricks-and-mortar banks, JNB runs a unique banking model that is conducted entirely online. Therefore, cybersecurity is absolutely critical for its business. Previously, the bank’s IT Supervision Department found it challenging to manage security risks. The department spent many hours digging out firewall and proxy logs from the office automation environment and analyzing web access logs to spot unauthorized accesses. The bank also required high accuracy in monitoring transaction logs to safeguard against spoofing and illegal fund transfers, and it needed to share information with Financials ISAC Japan.
JNB decided to establish an intelligent platform to collect, analyze and deliver real-time insights from machine-generated big data to improve its cyber defense strategies. Among all of the alternatives considered, JNB found that Splunk Enterprise was the best option.
