The Promise of Multi-Signer DNSSEC

DNSSEC is increasingly adopted by organizations to protect DNS data and prevent DNS attacks like DNS spoofing and DNS cache poisoning. At the same time, more DNS deployments are using proprietary DNS features like geo-routing or load balancing, which require special configuration to support using DNSSEC. When these requirements intersect with multiple DNS providers, the system breaks down. more

Global Payments Breach Confirmation

This morning, Global Payments held a conference call with investors and analysts covering their earlier breach announcement and projected earnings. Global Payments had also released an update advisory yesterday stating that "the company believes that the affected portion of its processing system is confined to North America and less than 1,500,000 card numbers have been exported" and that only Track 2 card data may have been stolen. more

Internet Population Passes 1 Billion, and We’re Still Afraid

We're learning this week that we have officially passed the one billion number in terms of people using the Internet. Eric Schonfeld writes in his article on TechCrunch that the number is probably higher than that. One billion is a staggering number, even though it makes up only 15 to 22 percent of the world's population. Nevertheless, those one billion Internet users give us a lot to deal with on their own in terms of social and security issues on the web. more

Privacy and Security - Five Objectives

It has been a very busy period in the domain of computer security. With "shellshock", "heartbleed" and NTP monlink adding to the background of open DNS resolvers, port 445 viral nasties, SYN attacks and other forms of vulnerability exploits, it's getting very hard to see the forest for the trees. We are spending large amounts of resources in reacting to various vulnerabilities and attempting to mitigate individual network attacks, but are we making overall progress? What activities would constitute "progress" anyway? more

Mac Hit by Another Wave of Malware… Users in Denial?

In case you haven't been watching cyber news recently, last week various security researchers published that Macs were infected by the Flashback Trojan and that the total number of infections worldwide was 600,000. This number was published by a couple of blogs. I debated writing about this topic since we had a previous Mac outbreak last year that initially spiked up, caused Apple to go into denial about the affair before issuing a fix, and then the malware kind of went away. Will this follow the same pattern? more

Nominet Rolls Out DNSSEC for 9.4 Million .UK Domains

UK registry Nominet has enabled the deployment of domain name system security extensions (DNSSEC) for 9.4 million second level .uk domains. Completing the rollout represents over a year's work and marks an important milestone in making the web a more trusted environment for UK consumers and businesses, says Nominet, which is responsible for running the .uk internet infrastructure. more

Schneier and Kerr on Encryption Workarounds

Bruce Schneier is a famous cryptography expert and Orin Kerr a famous cyberlaw professor. Together they've published a law journal article on Encryption Workarounds. It's intended for lawyers so it's quite accessible to non-technical readers. The article starts with a summary of how encryption works, and then goes through six workarounds to get the text of an encrypted message. more

Why Domain Name Security Matters Most?

In my recent CircleID post, DNS, Domain Names, and Certificates: The Missing Links in Most Cybersecurity Risk Postures, I highlighted the importance of applying multiple layers of defense to secure these business-critical assets. Last Friday, Brian Krebs, the world-renowned cybersecurity journalist, reiterated the criticality of domain name security because the domain name "e-hawk.net" was stolen from the rightful owner using social engineering tactics targeting its domain name registrar. more

Designing Secure Networks with Cisco Technology, Part 2

In this multipart series I will be presenting some of the leading industry-standard best practices for enterprise network security using Cisco technologies... In Part 1 of this series, I provided an overview of the critical role that properly designed data security architectures play within an Internet-connected organization. Before we begin to discuss the security designs, processes and recommendations related to Cisco technology, let's first discuss some of the ways a network becomes unsecure... more

Governments Changing Censorship Tactics as More Websites Adopt HTTPS

With websites and social media platforms moving from HTTP to secure HTTPs connections in recent years, a new degree of complication is affecting Internet censorship efforts around the world. more

Two Years Later WannaCry Continues to Spread to Vulnerable Devices, Nearly 5M Devices Affected

Two years after the initial wave of WannaCry attack in May of 2017, security researchers say the ransomware continues to spread to vulnerable devices. WannaCry infection has affected close to 5 million devices to date. more

Cyber Criminals Infiltrate Even Small Businesses

I read an interesting article in the Wall Street Journal today entitled Cyber Criminals Sniff out Vulnerable Firms. It's a story of a small business owner in New York whose company was broken into by cyber criminals and stole $1.2 million from its bank accounts, although the owner was able to later recover about $800,000 of that. The moral of the story is that small businesses feel like they are not a major target for online thefts like these. more

An Economic Outlook on Information Security

As enterprise information security spending is scrutinized in unprecedented fashion in 2009 Information Technology management will seek to get more for their security dollar. While budgets tighten and risks grow due to the global economic downturn IT departments will be looking for point solutions, not suites of security tools. more

Cybercriminals Shifting Focus From Windows PCs to Other Systems and Mobile

In a major cybercrime turning point, scammers have begun shifting their focus away from Windows-based PCs to other operating systems and platforms, including smart phones, tablet computers, and mobile platforms in general, according to the Cisco® 2010 Annual Security Report, released today. The report also finds that 2010 was the first year in the history of the Internet that spam volume decreased, that cybercriminals are investing heavily in "money muling," and that users continue to fall prey to myriad forms of trust exploitation. more

Deploying DNSSEC: Lessons from Domain Registrar Implementation

As a registrar at the front end of the DNSSEC deployment effort, our technical team has made a sustained investment in DNSSEC deployment so that our customers don't get overwhelmed by this wave of changes to the core infrastructure of the Domain Name System. Along the way, we've learnt a lot about how to implement DNSSEC which might hold useful lessons for other organizations that plan to deploy DNSSEC in their networks. more
