Rock solid appliance

DNSBOX300 is a hardened device, with a purpose-built Linux secure appliance architecture and an inbuilt firewall. There is no network access to the operating system, all unnecessary applications and OS components have been removed, access to unused ports denied and buffer overflows eliminated. Remote admin is via secure SSL encryption.

DNSBOX300 runs entirely from CompactFlash. With no disks in the system, the cause of 90% of hardware failures is eliminated, making this appliance 10x more reliable.

There are two CompactFlash cards used in the system. The first is bootable and contains the operating system (Linux, based on Slackware) and is mounted read-only at all times (other than when being patched). The second contains all settings and DNS data.

DNSBOX300 comes pre-installed, with a simple admin GUI. That means there’s no need to install OS and DNS server software, to patch the software for security vulnerabilities or to acquire and build BIND. With DNSBOX300, OS and BIND software upgrades are taken care of, eliminating another headache.

As a dedicated DNS appliance, DNSBOX300 builds on the strengths of Namesurfer. For DNS management – where 100% uptime is critical – the appliance format means maximum security and reliability. As a plug-and-play device, it offers further major savings in time, cost and hassle.
