UltraDNS Selected To Manage Tripwire's Internet Domains

Leading Infrastructure Integrity Firm Uses UltraDNS's Secure, 100 Percent Guaranteed DNS Infrastructure

SAN MATEO, Calif. November 19, 2001 -- UltraDNS™ Corporation, the leading Directory Infrastructure Services Provider (DISP) today announced that the leading infrastructure integrity company, Tripwire, Inc. has selected UltraDNS's Managed DNS ServiceT to host several of its mission-critical Internet domains and support its global e-security services with failsafe, 100 percent guaranteed Domain Name System (DNS) infrastructure.

Tripwire provides electronic security products and services to thousands of customers in 17 countries, and its GuardCentral Web portal provides visitors with breaking news on physical and cyber security issues and updates. Security issues were the foremost consideration for Tripwire to select UltraDNS's Managed DNS Service as an alternative to conventional Internet directory infrastructure. UltraDNS's proprietary directory infrastructure technology eliminates serious security vulnerabilities typically found in the 13-year-old, widely used public domain Berkeley Internet Name Domain (BIND) DNS software, and ultimately, prevents hackers from accessing critical corporate information.

"Tripwire can't afford for our Web sites to be anything less than available at all times - much less allow them to be compromised. UltraDNS provides a directory infrastructure for our domains that has proven to be a great choice for the Company," said Jon Speer, IS manager at Tripwire. "In effect, by choosing UltraDNS's solution we are ensuring our customers guaranteed access to the information and services critical to their security."

Security is one of the biggest problems with the BIND system for managing name directories, according to The SANS Institute, a Bethesda, Maryland cooperative research and education organization. The SANS Institute lists BIND-based domain name servers as the number one Internet security risk. According to SANS, name servers that run BIND aren't always up-to-date, and many have security holes. Such improperly configured name servers can give a hacker access to names, IP addresses, and a variety of other critical and sensitive information about internal systems. Since domain name servers are fairly static and typically are not checked frequently, hackers can break into a system and the problem usually isn't noticed until someone from the outside reports an attack originating from the name server system.

"Tripwire's decision to depend on UltraDNS's Managed DNS Service demonstrates the need for a secure alternative to BIND," said Michael Hotz, UltraDNS's vice president of software development. "Unfortunately, BIND open source code is the vulnerability that hackers most frequently exploit when targeting a company's mission-critical Web-based systems. UltraDNS's directory infrastructure platform frees IS managers from the burden of checking domain name servers and getting BIND patches - and gives everyone the peace of mind that these servers won't be an open door to the rest of a company's data assets."
