NTP is Still a Security Risk

The Network Time Protocol (NTP) has been in the news a number of times over the past couple of years because of attacks on the protocol, vulnerabilities in the daemon, and the use of NTP in DDoS attacks. In each case, the developers of NTP have responded quickly with fixes or recommendations for remediating these attacks. Additionally, the development team has continued to look ahead and has worked to enhance the security of NTP. Unfortunately, that has not translated to an improved security picture for NTP. more

Vendor Selection Matters in the Domain Registrar Ecosystem

Domain name abuse is one of the most dangerous and under-regulated issues in digital business security today. Many of the largest companies in the world still lack basic domain security protocols, making them prime targets for bad actors. An attack on a domain can lead to the redirection of a company's website, domain spoofing, domain and domain name system (DNS) hijacking attacks, phishing attacks, network breaches, and business email compromise (BEC). more

An Internet Security Operations Viewpoint of IGF

The Internet Governance Forum (IGF) is an annual UN conference on Internet governance which was held this year in Rio de Janeiro, Brazil. The topics discussed range from human rights online to providing Internet access in developing countries. A somewhat secondary topic of conversation is Internet security and cyber-crime mostly limited to policy and legislative efforts. Techies and Internet security industry don't have much to do there, but I have a few updates for us from the conference. more

Nom-Com Appoints Independent and Diverse Candidates to ICANN Leadership Positions

When 72 candidates vie for 8 positions, making tough choices are inevitable. ICANN's 2005 Nominating Committee (Nom-Com) on Friday announced the selection of a diverse and independent set of nominees for important roles in ICANN, including the Board of Directors, the Generic Names Supporting Organization (GNSO), the At-Large Advisory Council (ALAC) and the Country Code Names Supporting Organization (ccNSO). more

Letter from Rome

I am at the ICANN meeting in Rome. The big story here is that ICANN is under attack for not sticking to its narrow mission -- technical coordination of the DNS and IP numbering system. People here are referring obliquely to the VeriSign lawsuit as "recent events" (as in "in light of recent events"). This euphemism reminds me of words used to reference the US Civil War ("the late unpleasantness"). more

Can We Get More Eyes on Britain’s Largest Scam “Watch List”?

The FCA has been naming and shaming financial scam domains for decades. Its "warning list" is probably one the most extensive databases of its kind. But does it do a good enough job of actually warning people? Let us begin with the FCA website, which would not exactly get full points for user-friendliness: locating the "watch list" is a task in and of itself, to say nothing of consulting and scrutinising it. more

INTERPOL Leads Arrest of 1,209 Suspects in Pan-African Cybercrime Crackdown, Recovers $97 Million

Authorities across 18 African nations, aided by the United Kingdom and INTERPOL, have arrested 1,209 suspects and dismantled over 11,000 illicit cyber infrastructures. more

We Urgently Need a New Internet

Let's be honest about it. Nobody -- including those very clever people that were present at its birth -- had the slightest idea what impact the internet would have in only a few decades after its invention. The internet has now penetrated every single element of our society and of our economy, and if we look at how complex, varied and historically different our societies are, it is no wonder that we are running into serious problems with the current version of our internet. more

How Decades-Old Decisions Left U.S. Networks Vulnerable to Chinese Cyberintrusion

It seems like there is more disturbing news every day about Chinese infiltration of our telecommunications networks. A recent headline said that nine large ISPs have now been infiltrated. Tom Wheeler, a previous Chairman of the FCC, recently wrote an article for the Brookings Institute that speculates that the ability of the Chinese to infiltrate our networks stems back to decisions made decades ago that have never been updated for the modern world of sophisticated hacking. more

Verisign Will Help Strengthen Security With DNSSEC Algorithm Update

As part of Verisign's ongoing effort to make global internet infrastructure more secure, stable, and resilient, we will soon make an important technology update to how we protect the top-level domains (TLDs) we operate. The vast majority of internet users won't notice any difference, but the update will support enhanced security for several Verisign-operated TLDs and pave the way for broader adoption and the next era of Domain Name System (DNS) security measures. more

UN Cyberdiplomcy I: PoC, Cybercrime and the Global Digital Compact

Despite global polarization, recent UN cyber diplomacy has achieved three significant agreements in 2024: a cyber attack reporting system, a convention against cybercrime, and a "Global Digital Compact." These successes show that consensus on global issues is possible, though the vague wording of agreements raises concerns about their long-term effectiveness in ensuring security and peace. more

Increasing the Strength of the Zone Signing Key for the Root Zone

One of the most interesting and important changes to the internet's domain name system (DNS) has been the introduction of the DNS Security Extensions (DNSSEC). These protocol extensions are designed to provide origin authentication for DNS data. In other words, when DNS data is digitally signed using DNSSEC, authenticity can be validated and any modifications detected. more

8 Security Considerations for IPv6 Deployment

Feb. 3, 2011, came and went without much fanfare, but it was a milestone for Internet stakeholders, whether they knew it or not. On that Thursday, the last available IPv4 addresses were allocated by the Internet Assigned Numbers Authority (IANA). Though some Regional Internet Registries (RIRs) have a reasonable inventory of IP addresses that could last another year or two, the days of "new" IPv4 address allocations are largely over. more

Should the Government Prepare a Preemptive Cyber-Attack?

The House Committee on Science recently held a hearing to "examine the extent of U.S. vulnerability to cyber attacks on critical infrastructure such as utility systems, and what the federal government and private sector are doing, and should be doing, to prevent and prepare for such attacks." Specific issues addressed at the hearing included whether: 1) the U.S. is able to detect, respond to, and recover from cyber-attacks on critical infrastructure; and 2) is there a clear line of responsibility within the federal government to deal with cybersecurity... more

Security Costs Money. So - Who Pays?

Computer security costs money. It costs more to develop secure software, and there's an ongoing maintenance cost to patch the remaining holes. Spending more time and money up front will likely result in lesser maintenance costs going forward, but too few companies do that. Besides, even very secure operating systems like Windows 10 and iOS have had security problems and hence require patching. (I just installed iOS 10.3.2 on my phone. It fixed about two dozen security holes.) more
