021 Chasing Risky Internet Business

As security professionals, we’re relied upon to protect our networks from malicious traffic. But what’s the best strategy for determining the most likely sources of risky traffic? Is it safe to assume that traffic from certain countries is more suspicious than others, or that some hosting infrastructures are more likely to be compromised? With a growing consensus that IP blocklists are rapidly becoming obsolete, a more sophisticated approach is needed. Our guest today is Dr. Bill Ladd, chief data scientist at Recorded Future. He’s the author of the report, "From Chasing Risk Lists to ASN Policies: Large-Scale Analysis of Risky Internet Activity." The report takes a data-driven look at a variety of ways to determine risky ASNs and IP addresses. In this episode Bill Ladd gives us an overview of his team’s research and findings.
