between clients (stub resolvers) and resolvers: DNS over TLS in RFC 7858 (DoT) and DNS over HTTPS in RFC 8484 (DoH). As with all new internet protocols, DoT and DoH will continue to evolve as deployment experience is gained, and they're applied to more use cases. <a href="https://circleid.com/posts/20190826_dot_and_doh_guidelines_provisioning_resolvers" class="red"><span class="readmore">more</span></a> </p> <div class="postInfo pipedLinks"> <ul> <li>By <a href="https://circleid.com/members/3782" class="blue">Bruce Van Nice</a></li> <li>Aug 26, 2019</li> <li>Comments: 0</li> <li>Views: 9,151</li> </ul> </div> <h3><a href="https://circleid.com/posts/20150415_dns_based_ddos_diverse_options_for_attackers">DNS-Based DDoS: Diverse Options for Attackers</a></h3> <div class="byLine">Related Topics: <a href="/topics/cyberattack" class="red">Cyberattack</a>,  <a href="/topics/cybersecurity" class="red">Cybersecurity</a>,  <a href="/topics/ddos_attack" class="red">DDoS Attack</a>,  <a href="/topics/dns" class="red">DNS</a>,  <a href="/topics/malware" class="red">Malware</a>,  <a href="/topics/networks" class="red">Networks</a>,  <a href="/topics/threat-intelligence" class="red">Threat Intelligence</a>,</div> <p> Denial of service attacks have been around since the Internet was commercialized and some of the largest attacks ever launched relied on DNS, making headlines.

Although DNS servers are not usually the target of attacks they are often disrupted so attention from operation teams is required. There is no indication the problem is going away and attackers continue to innovate. <a href="https://circleid.com/posts/20150415_dns_based_ddos_diverse_options_for_attackers" class="red"><span class="readmore">more</span></a> </p> <div class="postInfo pipedLinks"> <ul> <li>By <a href="https://circleid.com/members/3782" class="blue">Bruce Van Nice</a></li> <li>Apr 15, 2015</li> <li>Comments: 0</li> <li>Views: 13,004</li> </ul> </div> <h3><a href="https://circleid.com/posts/20130918_dns_amplification_attacks_out_of_sight_out_of_mind_part_3">DNS Amplification Attacks: Out of Sight, Out of Mind?

These attacks continue to evolve. Early attacks focused on authoritative servers using "ANY" queries for domains that were well known to offer good amplification.

Major incidents like the Spamhaus attack Geoff mentions at the beginning of his post make headlines, but even small attacks create noticeable floods of traffic. These attacks are easy to launch and effective even with relatively modest resources and we see evidence they're occurring regularly. Although DNS servers are not usually the target of these attacks the increase in traffic and larger response sizes typically stress DNS infrastructure and require attention from operation teams. <a href="https://circleid.com/posts/20130823_dns_amplification_attacks_out_of_sight_out_of_mind" class="red"><span class="readmore">more</span></a> </p> <div class="postInfo pipedLinks"> <ul> <li>By <a href="https://circleid.com/members/3782" class="blue">Bruce Van Nice</a></li> <li>Aug 23, 2013</li> <li>Comments: 0</li> <li>Views: 12,903</li> </ul> </div> <h3><a href="https://circleid.com/posts/20120628_high_performance_dns_needs_high_performance_security">High Performance DNS Needs High Performance Security</a></h3> <div class="byLine">Related Topics: <a href="/topics/cyberattack" class="red">Cyberattack</a>,  <a href="/topics/cybercrime" class="red">Cybercrime</a>,  <a href="/topics/cybersecurity" class="red">Cybersecurity</a>,  <a href="/topics/dns" class="red">DNS</a>,  <a href="/topics/networks" class="red">Networks</a>,</div> <p> There's been a lot of emphasis on DNS performance lately because faster DNS contributes directly to a better user experience. There's an interesting flipside to DNS performance though, higher performance DNS servers may be better targets for cache poisoning attacks. Faster servers give attackers more opportunities to insert fake entries into the DNS - speed can kill (or at least inflict a nasty wound!) so it's important to understand the security implications if you're looking to upgrade DNS performance. <a href="https://circleid.com/posts/20120628_high_performance_dns_needs_high_performance_security" class="red"><span class="readmore">more</span></a> </p> <div class="postInfo pipedLinks"> <ul> <li>By <a href="https://circleid.com/members/3782" class="blue">Bruce Van Nice</a></li> <li>Jun 28, 2012</li> <li>Comments: 0</li> <li>Views: 10,210</li> </ul> </div> <h3><a href="https://circleid.com/posts/20120613_the_business_parallels_between_ipv6_and_dnssec">The Business Parallels Between IPv6 and DNSSEC</a></h3> <div class="byLine">Related Topics: <a href="/topics/cybersecurity" class="red">Cybersecurity</a>,  <a href="/topics/dns" class="red">DNS</a>,  <a href="/topics/dns-security" class="red">DNS Security</a>,  <a href="/topics/internet_protocol" class="red">Internet Protocol</a>,  <a href="/topics/ipv6-transition" class="red">IPv6 Transition</a>,  <a href="/topics/ipv4-markets" class="red"> IPv4 Markets</a>,</div> <p> For two things that would seem to be completely unrelated there is an interesting parallel between IPv6 and DNSSEC. In both cases there is a misalignment of interests between content providers and service?providers. Content providers aren't highly motivated to deploy IPv6 because only a small proportion of users have v6 connectivity and even fewer only have v6. Service providers aren't anxious to deploy IPv6? because there isn't a lot of content on v6, and virtually none exclusively on v6 - so they don't expand the universe of interesting stuff on the web by deploying IPv6. Basically the same things could be said about DNSSEC. <a href="https://circleid.com/posts/20120613_the_business_parallels_between_ipv6_and_dnssec" class="red"><span class="readmore">more</span></a> </p> <div class="postInfo pipedLinks"> <ul> <li>By <a href="https://circleid.com/members/3782" class="blue">Bruce Van Nice</a></li> <li>Jun 13, 2012</li> <li>Comments: 1</li> <li>Views: 10,215</li> </ul> </div> <h3><a href="https://circleid.com/posts/20120522_a_logical_place_to_start_the_ipv6_transition">A Logical Place to Start the IPv6 Transition</a></h3> <div class="byLine">Related Topics: <a href="/topics/ddos_attack" class="red">DDoS Attack</a>,  <a href="/topics/dns" class="red">DNS</a>,  <a href="/topics/ipv6-transition" class="red">IPv6 Transition</a>,  <a href="/topics/ipv4-markets" class="red"> IPv4 Markets</a>,</div> <p> The transition to IPv6 is top of mind for most service providers. Even in places where there are still IPv4 addresses to be had surveys we've run suggest v6 is solidly on the priority list. That's not to say everyone has the same strategy. Depending where you are in the world transition options are different -- in places such as APAC where exhaustion is at hand one of the many NAT alternatives will likely be deployed since getting a significant allocation of addresses is not going to happen and other alternatives for obtaining addresses will prove expensive. <a href="https://circleid.com/posts/20120522_a_logical_place_to_start_the_ipv6_transition" class="red"><span class="readmore">more</span></a> </p> <div class="postInfo pipedLinks"> <ul> <li>By <a href="https://circleid.com/members/3782" class="blue">Bruce Van Nice</a></li> <li>May 22, 2012</li> <li>Comments: 0</li> <li>Views: 10,583</li> </ul> </div> <h3><a href="https://circleid.com/posts/20120502_spam_from_mobile_networks_who_woulda_thought">Spam from Mobile Networks?

This is counter intuitive at first glance because when most people think of mobile they think of smartphones, and those aren't known to be sources of spam (at least not yet). What's really going on is PCs connected to mobile networks with air cards, or tethered with a smartphone where it's permissible, are the culprits <a href="https://circleid.com/posts/20120502_spam_from_mobile_networks_who_woulda_thought" class="red"><span class="readmore">more</span></a> </p> <div class="postInfo pipedLinks"> <ul> <li>By <a href="https://circleid.com/members/3782" class="blue">Bruce Van Nice</a></li> <li>May 02, 2012</li> <li>Comments: 2</li> <li>Views: 9,878</li> </ul> </div> <h3><a href="https://circleid.com/posts/20120418_driving_dnssec_need_for_integration_of_all_the_functions_needed">Driving DNSSEC: The Need for Integration of All the Functions Needed</a></h3> <div class="byLine">Related Topics: <a href="/topics/cybersecurity" class="red">Cybersecurity</a>,  <a href="/topics/dns" class="red">DNS</a>,  <a href="/topics/dns-security" class="red">DNS Security</a>,</div> <p> DNSSEC continues to gain momentum as network operators and domain owners watch and learn from early adopters.
