Verisign Expands MANRS Relationship to Strengthen Global Routing Security

Verisign has been involved with an initiative known as Mutually Agreed Norms for Routing Security, or MANRS, since its inception. MANRS, which is coordinated by the Internet Society, focuses on strengthening the security and resiliency of IP networks throughout the world by identifying and providing best practices for mitigating common routing security threats.

MANRS began as a collaboration among network operators and internet exchange providers, with Verisign formally becoming a participant in its Network Operator Program in 2017. Since then, with the help of Verisign and other MANRS participants, the initiative has grown to also include content delivery networks (CDN) and cloud providers.

Recognizing Lessons Learned From the First DNSSEC Key Rollover, a Year Later

A year ago, under the leadership of the Internet Corporation for Assigned Names and Numbers (ICANN), the internet naming community completed the first-ever rollover of the cryptographic key that plays a critical role in securing internet traffic worldwide. The ultimate success of that endeavor was due in large part to outreach efforts by ICANN and Verisign which, when coupled with the tireless efforts of the global internet measurement community, ensured that this significant event did not disrupt internet name resolution functions for billions of end users.

Unexpected Effects of the 2018 Root Zone KSK Rollover

March 22, 2019 saw the completion of the final important step in the Key Signing Key (KSK) rollover – a process which began about a year and half ago. What may be less well known is that post rollover, and until just a couple days ago, Verisign was receiving a dramatically increasing number of root DNSKEY queries, to the tune of 75 times higher than previously observed, and accounting for ~7 percent of all transactions at the root servers we operate.

Revisiting How Registrants Can Reduce the Threat of Domain Hijacking

Recent events1,2 have shown the threat of domain hijacking is very real; however, it is also largely preventable. As Verisign previously noted3, there are many security controls that registrants can utilize to help strengthen their security posture. Verisign would like to reiterate this advice within the context of the recent domain hijacking reports.

Operational Update Regarding the KSK Rollover for Administrators of Recursive Name Servers

Currently scheduled for October 11, 2018, the Internet Corporation for Assigned Names and Numbers (ICANN) plans to change the cryptographic key that helps to secure the internet’s Domain Name System (DNS) by performing a Root Zone Domain Name System Security Extensions (DNSSEC) key signing key (KSK) rollover.

DNS-Based Threats: Cache Poisoning

The Domain Name System (DNS) is the cornerstone of communication for the internet. Navigating to the sites you access every day often starts with a DNS request. Cybercriminals recognize the value of DNS and may look for ways to abuse improperly secured DNS to compromise its uptime, integrity or overall response efficacy—which makes DNS an important area for enforcing security and protecting against threats.

One such threat: cache poisoning. (more…)

A Framework for Resilient DNS Security: DNS Availability Drives Business

To establish connectivity with other users and devices, almost anything that interfaces with the internet depends on the accuracy, integrity and availability of the Domain Name System (DNS). Most online transactions and data movement are critically dependent on DNS services.

As such, DNS is an important point of security enforcement and a potential point in the Cyber Kill Chain for many cyber-attacks. Organizations are beginning to recognize this and are using DNS security mechanisms as a first line of defense for preventing or mitigating online threats.

Verisign’s Perspective on Recent Root Server Attacks

On Nov. 30 and Dec. 1, 2015, some of the Internet’s Domain Name System (DNS) root name servers received large amounts of anomalous traffic. Last week the root server operators published a report on the incident. In the interest of further transparency, I’d like to take this opportunity to share Verisign’s perspective, including how we identify, handle and react, as necessary, to events such as this.

How DANE Strengthens Security for TLS, S/MIME and Other Applications

The Domain Name System (DNS) offers ways to significantly strengthen the security of Internet applications via a new protocol called the DNS-based Authentication of Named Entities (DANE). One problem it helps to solve is how to easily find keys for end users and systems in a secure and scalable manner. It can also help to address well-known vulnerabilities in the public Certification Authority (CA) model. Applications today need to trust a large number of global CAs. There are no scoping or naming constraints for these CAs – each one can issue certificates for any server or client on the Internet, so the weakest CA can compromise the security of the whole system. As described later in this article, DANE can address this vulnerability.

3 Tips for Improving Your Website DNS Performance During the Holidays

With the biggest shopping season just around the corner, it is more important than ever that your website is available and consumers can find it. As companies add eye-catching images, social share buttons and attractive promotions to grab consumers’ attention, they may also inadvertently be slowing down their website.
47% of customers expect a page to load in 2 seconds

For consumers who are increasingly impatient and expect a website to load within two seconds or less, the majority will quickly abandon a slow-loading page along with their shopping cart, resulting in lost revenue. With so many potential problems to slow down your site, the domain name system (DNS) doesn’t have to be one of them.

What is DNS?

DNS is the Internet’s equivalent to a phone book. It maintains a directory of domain names and translates them to their respective Internet Protocol (IP) addresses, enabling the end user to access a desired Web page. Any disruption to the DNS during the holiday season can be disastrous for retailers.

“DNS is the Achilles’ heel of the Web, often forgotten, and its impact on website performance is ignored until it breaks down,” explains Mehdi Daoudi, CEO of Web performance monitoring firm Catchpoint. However, it doesn’t have to be.
