97% of All Global 2000 Companies at Risk from SAD DNS Attack

There is a new threat in town known as "SAD DNS" that allows attackers to redirect traffic, putting companies at risk of phishing, data breach, reputation damage, and revenue loss. What is SAD DNS? No, it isn't the domain name system (DNS) feeling moody, but an acronym for a new-found threat -- "Side-channel AttackeD DNS" discovered by researchers that could revive DNS cache poisoning attacks. more

IETF Releases the New and Improved Internet Security Protocol, TLS 1.3

Internet Engineering Task Force (IETF) has announced the official release of TLS 1.3. more

Australian Government Issues New Guidelines to Address 5G Security Concerns in Smart Cities

The Australian Signals Directorate (ASD) has issued a new set of guidelines warning about the security risks posed by the use of 5G technology in so-called Smart Cities. The ASD's concerns align with those of the Five Eyes security alliance, which has warned that the interconnected nature of a fully connected city makes it vulnerable to cyberattacks. more

How to Take a Proactive Approach to DNS Health

Because DNS is such an omnipresent part of modern networking, it's easy to assume that functional DNS infrastructure can be left running with minimal adjustments and only needs to be investigated in the event of a malfunction. Yet there are small telltale signs that precede DNS issues -- and knowing what they are can help to prevent disruption before it happens. more

Three Reasons Why CISOs Need to Understand Domain Security

Domain name abuse is one of the most dangerous and under-regulated issues in digital business security today. An attack on a web domain can lead to the redirection of a company's website, domain spoofing, phishing attacks, network breaches, and business email compromise (BEC). Domains used as a company's online world are part of an organization's external attack surface and need to be continuously monitored for cybercrime attacks and fraud. more

Government Regulation of Cybersecurity: Partnership (or Power Grab) in the Making?

A cybersecurity bill introduced in the U.S. Senate on April 1st, 2009 would give the United States federal government extraordinary power over private sector Internet services, applications and software. This proposed legislation is a direct result of a review ordered by the Obama administration into government policies and processes for defending against Internet-born attack. The focus of the bill, according to a summary released by the sponsoring senators, is on establishing a new partnership between the public and private sectors in a joint effort to bolster Internet security... more

Minimum Disclosure: What Information Does a Name Server Need to Do Its Job?

Two principles in computer security that help bound the impact of a security compromise are the principle of least privilege and the principle of minimum disclosure or need-to-know. As described by Jerome Saltzer in a July 1974 Communications of the ACM article, Protection and the Control of Information Sharing in Multics, the principle of least privilege states, "Every program and every privileged user should operate using the least amount of privilege necessary to complete the job." more

Advancing Cyberstability: Protect the Public Internet Core and Improve Cyber Hygiene

The Paris Peace Forum (PPF), established by the French president Emanual Macron, was picked by the Global Commission for Stability in Cyberspace (GCSC) to launch its final report "Advancing Cyberstability" for good reasons: The Internet isn't just a purely technical issue with some political implications anymore. On the eve of the 2020s, the management of cyberspace is a global problem, a matter of international security, a question of war or peace. more

Brazil: The Newest Up and Comer

The Virus Bulletin Conference last month had some good presentations, including this one by Fabio Assolini of Kaspersky. He spoke about how Brazil is the the newest up-and-comer on the cyber crime block. The tale begins with the story of Igor and Emily, two cyber criminals operating out of Brazil. Together, the two of them stole $300,000 US from a single Brazilian bank in one year. more

EU CRA: Regulatory Extremism and Exceptionalism

European Union (EU) legislators, like most of the world, are troubled about the increasing number and severity of cybersecurity incidents. However, unlike most of the world, which is taking a flexible, adaptive Zero Trust Model approach of continuous controls for cyberdefense, the EU government is pursuing a vastly expanded version of the failed Common Criteria certification model coupled with regulatory extremism and exceptionalism strategies. more

ICANN Begins Publishing Monthly Reports on Generic Top-Level Domain Security Threats

ICANN has published its first new monthly report providing statistics and insight into security threats to generic top-level domains (gTLDs). more

Why Private Support of Cyber Security Initiatives May Not Work

A fledgling international cyber security alliance is continuing to gather backing from private business, according to a recent article published on ComputerWeekly.com. The International Cyber Security Protection Alliance (ICSPA) aims to support law enforcement agencies in countries that lack the resources to fight cybercrime. Commercial security organizations such as McAfee and Trend Micro are supporting the alliance. more

DNSSEC and DNS over TLS

The APNIC Blog has recently published a very interesting article by Willem Toorop of NLnet Labs on the relationship between Security Extensions for the DNS (DNSSEC) and DNS over Transport Layer Security. Willem is probably being deliberately provocative in claiming that "DoT could realistically become a viable replacement for DNSSEC." If provoking a reaction was indeed Willem's intention, then he has succeeded for me, as it has prompted this reaction. more

Warning, Danger Lurks Here: Exploring DKIM/ADSP Edge Cases - Missing message-id

This article is the first in an occasional series on DKIM/ADSP edge cases that may not be generally recognized or understood. Many people advocate DKIM/ADSP adoption without fully recognizing potential implementation and operational issues. The fact is that the email messaging environment is fraught with opportunities for poor outcomes because of common practices that need to be considered or poorly understood implementations that are not considered... more

MIT Spam Conference: 2010 Call for Papers and Participation

I am proud (or disappointed) to announce the 8th annual MIT Spam Conference, March 25th and 26th at MIT in Cambridge, Massachusetts. A regular research competition that brings out the best minds in the fight against unsolicited email. At this point it would be helpful to provide a little background on the conference and remind everyone that the Call For Papers is still open. more
