10 Things to Know About the Cost of DNS Attacks

The top challenge most organizations face in protecting networks against Domain Name Service (DNS)-based attacks is the cost of security solutions. Infoblox, a network control solutions firm, recently sponsored a survey on DNS protection which shows that many organizations hesitate to adopt new security solutions because of the cost. The price of an attack, however, can be much more, as the survey results reveal. There is also a troubling lack of consensus on how to leverage DNS technology to block potential malicious activity, the Infoblox report notes. Most organizations currently use DNS Response Policy Zones (RPZs) to block malicious domains, and larger organizations (1,000+ employees) are significantly more likely to be using DNS RPZs versus organizations with less than 1,000 employees, 43 percent vs. 10 percent, respectively, according to the report. Also, smaller organizations are significantly more likely to use a free or open source feed to create a DNS blacklist than a larger organization (38 percent vs. 13 percent, respectively).The Infoblox survey was conducted online and included 128 respondents based in the U.S. and Canada.
