March has seen the first of the DNS Operations, Analysis, and Research Center (OARC) workshops for the year, where two days of too much DNS is just not enough!

Have We Reached Peak Use of DNSSEC?

The story about securing the DNS has a rich and, in Internet terms, protracted history. The original problem statement was simple: how can you tell if the answer you get from your query to the DNS system is 'genuine' or not? The DNS alone can't help here.

DDOS and the DNS

The Mirai DDOS attack happened just over a year ago, on the 21st October 2016. The attack was certainly a major landmark regarding the sorry history of "landmark" DDOS attacks on the Internet. It's up there with the Morris Worm of 1988, Slammer of 2002, Sapphine/Slammer of 2009 and of course Conficker in 2008. What made the Mirai attack so special? more

An Overview of the 27th DNS Operations, Analysis, and Research Center Meetings

The DNS Operations, Analysis, and Research Center (DNS-OARC) meetings are an instance of a meeting that concentrates on the single topic of the DNS, and in this case, it delves as deep as anyone is prepared to go! It's two days where too much DNS is barely enough!

On Sept. 27, Internet Corporation for Assigned Names and Numbers (ICANN) announced that the first root zone Key Signing Key (KSK) rollover - originally scheduled to take place on Oct. 11 - will be postponed. Although this was certainly a difficult decision, we fully agree that erring on the side of caution is the best approach to take. In this blog post, I want to explain some of the involvement Verisign has had in KSK rollover preparations, as well as some of the recently available research opportunities which generated data that we shared with ICANN related to this decision. more

Failing to block a stealthy malicious host from making connections to your network could cost your company millions of dollars, a damaged reputation, and severe losses in sensitive private data. Threat intel teams have faced on-going problems: Expensive feeds that are slow to catch new threats; Chasing false positives in alerts wastes time and money; and Vendors selling a new appliance for every ill. Would 100% of your users Spot the Bot? more
