In Network Security Design, It’s About the Users

One of the longstanding goals of network security design is to be able to prove that a system -- any system -- is secure. Designers would like to be able to show that a system, properly implemented and operated, meets its objectives for confidentiality, integrity, availability and other attributes against the variety of threats the system may encounter. A half century into the computing revolution, this goal remains elusive. more

Australia Booting Infected Computers Off Their Networks

The Australian has a good article describing the efforts some of their ISPs are making in an attempt to clean up their act: the government is encouraging ISPs to detect computers on their network that are infected and part of botnets, and to communicate to the customer that their system is compromised... Unless the customer feels a little bit of pain they will not change their ways. more

DNS Amplification Attacks: Out of Sight, Out of Mind? (Part 3)

Previous posts (Part 1 and Part 2) offer background on DNS amplification attacks being observed around the world. These attacks continue to evolve. Early attacks focused on authoritative servers using "ANY" queries for domains that were well known to offer good amplification. Response Rate Limiting (RRL) was developed to respond to these early attacks. RRL, as the name suggests, is deployed on authoritative servers to rate limit responses to target names. more

According to the Department of Homeland Security, Cybercrime Is a Bigger Threat Than Terrorism

An article in Forbes the other day reports on US Secretary of Homeland Security Janet Napolitano's comments that 'cybercrime represents the "greatest threat and actual activity that we have seen aimed at the west and at the United States" in addition to "or other than Al Qaeda and Al Qaeda-related groups."' ..."Napolitano cited a study commissioned by Symantec that put the total worldwide cost of cybercrime at $388 billion -- higher than the global market for heroin, cocaine and marijuana combined." more

Microsoft Warns Extortion Drives Majority of Attacks Amid AI Escalation, Identity Collapse, and Global Fragmentation

Microsoft's latest Digital Defense Report reveals how cybercriminals and nation-states are rapidly adopting AI to enhance attacks. With identity-based threats soaring, the company urges urgent modernization of security systems and global cooperation. more

At the Start of the NL IGF

At the annual Dutch "delegation" dinner at the Internet Governance Forum (IGF) in Vilnius, Lithuania, I voiced that it may be a good idea to start a Dutch IGF. This followed a discussion in which we discussed the possibilities of involving more people and organisations from the Netherlands in Internet governance. The, now, Ministry of Economic Affairs, Agriculture and Innovation followed this thought and made it possible for the ECP/EPN foundation to start the NL IGF. more

An Update From CIRA on IoT Security

Last April, I shared information about a multistakeholder process that CIRA is part of, which seeks to identify and guide the development of policy around the Internet of Things (IoT), putting security at the heart of internet innovations in Canada. Since the formation of this process, we've made quite a bit of progress and I'm pleased to share some of that with you. more

Securing the Routing System at NANOG 74

The level of interest in the general topic of routing security seems to come in waves in our community. At times it seems like the interest from network operators, researchers, security folk and vendors climbs to an intense level, while at other times the topic appears to be moribund. If the attention on this topic at NANOG 74 is anything to go by we seem to be experiencing a local peak. more

The Recent DDoS Attacks on Banks: 7 Key Lessons

Starting in mid-September, one of the largest and most sophisticated DDoS attacks ever targeted the titans of American banking. Initially, victims included Bank of America, JPMorgan Chase, Wells Fargo, PNC Bank, and U.S. Bancorp. In the weeks to come, others would also feel the pain. Websites crashed, customers were unable to make transactions and IT professionals and PR gurus went into panic mode. Leon Panetta, U.S. Secretary of Defense, said the attacks foreshadowed a "Cyber Pearl Harbor." more

Malware and Botnet Operators Setting Up Their Own Data Centers

Dennis Fisher of Thread Post reports: "The malware writers and criminals who run botnets for years have been using shared hosting platforms and so-called bulletproof hosting providers as bases of operations for their online crimes. But, as law enforcement agencies and security experts have moved to take these providers offline, the criminals have taken the next step and begun setting up their own virtual data centers." more

11 Information Economy Policy Reversals Coming to a Marketplace Near You!

In the wake of the election, sweeping policy shifts in the information economy are set to accelerate. Expect fast-tracked FCC reforms, Starlink subsidies, and AI-driven oversight to redefine media, tech, and regulatory landscapes. From relaxed antitrust to intensified media control, these eleven reversals signal a move toward deregulation and Chicago School libertarianism, with lasting impacts on U.S. markets and governance. more

Why More Effort Won’t Solve the Exceptional Access Problem

In the debate over government "exceptional access" to encrypted communications, opponents with a technical bent (and that includes me) have said that it won't work: that such a scheme would inevitably lead to security problems. The response -- from the policy side, not from technical folk - has been to assert that perhaps more effort would suffice. FBI Director James Comey has said, "But my reaction to that is: I'm not sure they've really tried." Hillary Clinton wants a "Manhattan-like project, something that would bring the government and the tech communities together". More effort won't solve the problem - but the misunderstanding lies at the heart of why exceptional access is so hard. more

A Cynic’s View of 2015 Security Predictions - Part 3

A number of security predictions have been doing the rounds over the last few weeks, so I decided to put pen to paper and write a list of my own. However, I have a quite a few predictions so I have listed them over several blog posts. After all, I didn't want to bombard you with too much information in one go! Part three examines the threats associated with data breaches. more

Unintended Benefits of Trump’s Twitter Tantrum

Four years ago, progressive intergovernmental organizations like the European Union became increasingly concerned about the proliferation of hate speech on social media. They adopted legal mechanisms for removing Twitter accounts like Donald Trump's. The provisions were directed at Facebook, Twitter, and YouTube. In June of 2016, a "deconstruction" of these mechanisms was presented to one of the principal global industry standards bodies with a proposal to develop new protocols to rapidly remove such accounts. more

Canada’s Electronic Spy Agency Makes Its Malware Analysis Tool Public

Canada's Communications Security Establishment (CSE) which rarely discloses detail of its activities has taken the "unprecedented step" of releasing one of its own cyber defense tools to the public, in a bid to help companies and organizations better defend their computers and networks against malicious threats. more
