Case Study: Fukuoka University strengthens campus-wide security and simplifies DNS management with Infoblox Threat Defense

Fukuoka University blocks 34M unauthorized DNS requests with Infoblox

Fukuoka University, a large Japanese educational institution, faced challenges in managing its complex campus network with an error-prone manual DNS system. They also needed to secure a vast BYOD-heavy network against threats without deploying endpoint software or impacting users. The university turned to vendor Infoblox and its NIOS DDI and Threat Defense solutions to address these issues.

Infoblox provided a solution centered on securing the DNS layer. They implemented Protective DNS to block malicious connections and Outbound Port 53 Blocking to ensure all queries were inspected. This approach saved 120-170 hours annually on DNS management and blocked over 34 million malicious resolution attempts in a single month. The Infoblox solution provided stronger security with no user complaints and no performance impact.
