OpenDNS: Investigate

摘要

OpenDNS is an interesting concept. It offers two choices for users: no-cost for personal use and a paid version for commercial use. The idea behind OpenDNS is that the company provides an assured, independent, secure set of domain name servers. When top-level domain servers are compromised by attacks such as cache poisoning, OpenDNS servers can be relied on to provide safe domain name service. As a result, engineers at OpenDNS have developed tools they use to manage, mon- itor and investigate potential cyberthreats, especially those that impact name servers directly. One of those tools is Investigate. The purpose for Investigate is simple, although its use can become complicated and tedious depending on what you want to know and whether you are running the tool manually or from the API. But, we are getting a bit ahead of ourselves and giving, perhaps, the impression that this is an incomplete or poorly thought-out tool. In fact, nothing could be further from the truth.
