Privacy campaigners say such systems could be used as tools of oppression. In Moscow, Vyborov and countless others now face that oppression on a daily basis.

The general problem statement for technological standards is how to avoid the power imbalance of a single source for essential goods and services; in other words, standards are a line of defense against concentration risk. Interoperability is the goal, and multiple suppliers is the proof.

In this episode, they focus particularly on how social media has become a place where predators will search and highlight childrenâ€s vulnerabilities — which so many young people share online.

Tech policy, however, has its own set of “culture war issues” including net neutrality and encryption that largely serve as a distraction from the real issues at stake. Victims of child porn are now caught in the fray.

A major escalation in official online censorship regimes is progressing rapidly in Brazil, with implications for everyone in the democratic world. Under Brazil’s new government headed by President Lula da Silva, the country is poised to become the first in the democratic world to implement a law censoring and banning “fake news and disinformation” online, and then punishing those deemed Continue reading

Hedge 168: Roundtable

It’s roundtable time! In February’s roundtable, Eyvonne joins Tom and Russ to talk about Network as a Service, innovation, and marketing. Then we jump into the topic of the year at this point—ChaptGPT. Finally, we talk about proposals to eliminate noncompete agreements in the United States. What would this mean? Would it be better for tech, or worse?

As always, you can listen to the show on just about any podcatcher, you can listen right here, or you can download the show to listen later.

A decade ago, waferscale architectures were dismissed as impractical. Five years ago, they were touted as a fringe possibility for AI/ML. But the next decade might demonstrate waferscale as one of only a few bridges across the post-Mooreâ€s Law divide, at least for some applications.

This is not a ‘silver bullet’, however. In comparison to the sophisticated deception available in traditional IT security, deception in ICS still faces some challenges.

As a numbers guy, Iâ€m always intrigued by the Ookla Speedtest Global Index since it provides an interesting look at broadband speeds in the U.S. and around the world.

Two new separate sets of research released this month underscore real, hidden dangers to physical operations in today’s OT networks from wireless devices, cloud-based applications, and nested networks of programmable logic controllers (PLCs) — effectively further dispelling conventional wisdom about the security of network segmentation as well as third-party connections to the network.

As organizations strengthen their defenses and take a more proactive approach to protection, attackers are adapting their techniques and increasing the sophistication of their operations.

As the security of the Android Platform has been steadily improved, some security researchers have shifted their focus towards other Continue reading

Chatbot Attack Vectors

My monthly post is up over at Packet Pushers—

Machine learning systems “learn” from existing data pools and user interactions and are given “guardrails” by the system’s designers. Let’s look at some possible attack vectors and failure modes of these systems, specifically how training data, interaction with users, and the choice of guardrails might interact with security and privacy.

Chatbot Attack Vectors And Failure Modes In Networking And IT

With the release of ChatGPT as a product, Microsoft brought Machine Learning (ML) and Artificial Intelligence (AI) back into focus for millions of users—including network operators, coders, and other folks in information technology. People are once against asking if this technology will make them redundant or how it might change their day-to-day jobs. As always, […]

In Emoi Services LLC v. Owners Insurance Company, the Ohio Supreme Court recently found software is an intangible item that cannot experience direct physical loss or damage and, therefore, the plaintiffâ€s inability to access or use its software during a ransomware attack was outside the scope of its “businessowners” policy.

Searching Google for downloads of popular software has always come with risks, but over the past few months, it has been downright dangerous, according to researchers and a pseudorandom collection of queries.

Here’s a provocative question: Is it possible, given the vast array of security threats today, to have too many security tools?

This debate has proved futile for two reasons. First, the characteristics of any specific application will dictate which venue is more expensive — there is no simple, unequivocal answer. Second — the question implies that a buyer would choose a cloud or on-premises data center primarily because it is cheaper. This is not necessarily the case

The RISC-V architecture looks set to become more prevalent in the high performance computing (HPC) sector, and could even become the dominant architecture, at least according to some technical experts in the field.

Hedge 166: Oblivious DoH with Chris Wood

DNS over HTTPS, or DoH, is designed to protect the end user’s DNS queries from last mile providers—but recursive servers (or resolvers) also have full access to what a user is asking for. How can users preserve their privacy against data collection at recursive servers? ODoH provides one answer. Listen in as Tom Ammon, Chris Wood, and Russ White discuss how ODoH works, and what this means for user privacy.

Upcoming Course: How Routers Really Work

I’m teaching a course on router internals over at Safari Books Online on the 24th (in 10 days). From the descriptions:

A network device—such as a router, switch, or firewall—is often seen as a single “thing,” an abstract appliance that is purchased, deployed, managed, and removed from service as a single unit. While network devices do connect to other devices, receiving and forwarding packets and participating in a unified control plane, they are not seen as a “system” in themselves.

The course is three hours. I’m in the process of updating the slides … or rather, I need to get to updating the slides in the next couple of days.

The Internet Systems Consortium (ISC) has released patches to address multiple security vulnerabilities in the Berkeley Internet Name Domain (BIND) 9 Domain Name System (DNS) software suite that could lead to a denial-of-service (DoS) condition.

Going into 2023, phishing is still as large a concern as ever. “If it ainâ€t broke, donâ€t fix it,” seems to hold in this tried-and-true attack method.

This follow-up post describes what techniques exist to enumerate subdomains in a DNSSEC-enabled zone and what countermeasures exist to prevent it. DNSSEC itself is not explained further, however, some relevant record types are briefly described.

In 1987 economics Nobel Laureate Robert Solow said that the computer age was everywhere—except in productivity data. A similar thing could be said about AI today: It dominates tech news but does not seem to have boosted productivity a whit.
