In this study, we investigate DoT using 3.2k RIPE Atlas home probes deployed across more than 125 countries in July 2019. We issue DNS measurements using Do53 and DoT, which RIPE Atlas has been supporting since 2018, to a set of 15 public resolver services (five of which support DoT), in addition to the local probe resolvers, shown in the figures below.
In the early days of congestion control signaling, we originally came up with the rather crude “Source Quench” control message, an ICMP control message sent from an interior gateway to a packet source that directed the source to reduce its packet sending rate.
Posture assessment requires periodic comparisons of current controls to expected values. Having posture assessment as part of products when deployed is possible, but it will take some time until the industry can provide these capabilities.
The latest Honeywell USB Threat Report 2020 indicates that the number of threats specifically targeting Operational Technology systems has nearly doubled from 16% to 28%, while the number of threats capable of disrupting those systems rose from 26% to 59% over the same period.
In fact, much of the information required to detect most commonly encountered threats and malicious techniques can be drawn right from Windows event logs and systems monitoring, according to a new report by security vendor Red Canary.
Part of being a registry is being a phonebook for the Internet. But just as phonebooks have changed, so too are registries evolving. A core aspect of the ‘phonebook’ service that registries provide are known as ‘whois’ databases.
Cybercriminal extortionists have adopted a new tactic to apply even more pressure on their corporate victims: contacting the victims’ customers, and asking them to demand a ransom is paid to protect their own privacy.
ISPs in the U.S. saw a significant surge in both downstream and upstream traffic, increasing at least 30% and as much as 40% during peak business hours and as much as 60% in some markets, according to a new report from the Broadband Internet Technical Advisory Group (BITAG).
It is straightforward to reveal a user’s visited site if the destination IP address hosts only that particular domain. However, when a given destination IP address serves many domains, an adversary will have to ‘guess’ which one is being visited.
When it comes to cybersecurity, industrial IT—consisting mainly of operational technology (OT) and industrial control systems (ICS)—has failed to keep up with development in the enterprise IT world. That’s mostly because industries’ adoption of internet technology has been slower when compared with enterprises.
DNS Shotgun is a benchmarking tool specifically developed for realistic performance testing of DNS resolvers. Its goal is to simulate real clients and their behaviour, including timing of queries and realistic connection management, which are areas where traditional tools are lacking.
Tens of millions of Internet connected devices — including medical equipment, storage systems, servers, firewalls, commercial network equipment, and consumer Internet of Things (IoT) products — are open to potential remote code execution and denial-of-service attacks because of vulnerable DNS implementations.
The Resource Public Key Infrastructure (RPKI) is a specialized PKI designed and deployed to improve the security of the Internet BGP routing system. Some of the ‘resources’ that make up the RPKI include IP address prefixes and Autonomous System numbers (ASNs).
New research into 5G architecture has uncovered a security flaw in its network slicing and virtualized network functions that could be exploited to allow data access and denial of service attacks between different network slices on a mobile operator’s 5G network.
The “Milan” Epyc 7003 processors, the third generation of AMD’s revitalized server CPUs, is now in the field, and we await the entry of the “Ice Lake” Xeon SPs from Intel for the next jousting match in the datacenter to begin.
And just as these bad actors know that a highly successful way to weaken a business is to disrupt its supply chain, the same goes for cybercrime. It’s time to turn the tables on cybercriminals and use their own tactics against them.
Do you remember all the apprehension about cloud migration in the early days of cloud computing? Some of the concerns ran the full paranoia gamut from unreliability to massive overcharging for cloud services. Some concerns, such as the lack of security of the entire cloud infrastructure, rose to the level of conspiracy theories. It is nice to know that those myths are all behind us.
Though human errors — such as falling for phishing scams that result in data compromise or credential theft — remain one of the top security risks for organizations today, few appear to be making much progress in addressing the problem.
For two decades now, Google has demonstrated perhaps more than any other company that the datacenter is the new computer, what the search engine giant called a “warehouse-scale machine” way back in 2009 with a paper written by Urs Hölzle, who was and still is senior vice president for Technical Infrastructure at Google, and Luiz André Barroso, who is vice president of engineering for the core products at Google and who was a researcher at Digital Equipment and Compaq before that.
We are on a path that will see information security transformed in the next 5-10 years. There are five trends that will enable us as an industry to improve the overall security posture and reduce the surface attack space. There is evidence that we are already moving in that direction with a push for built-in security, but we must be mindful to ensure management scales.
Few things elicit terror quite like switching on a computer and viewing a message that all its files and data are locked up and unavailable to access. Yet, as society wades deeper into digital technology, this is an increasingly common scenario.
Forty years ago, the word “hacker” was little known. Its march from obscurity to newspaper headlines owes a great deal to tech journalist Steven Levy, who in 1984 defied the advice of his publisher to call his first book Hackers: Heroes of the Computer Revolution.
It’s easy to get overwhelmed with the number of cloud security resources available. How do you know which sources to trust? Which ones should inform your security strategies? Which reports will actually improve your cloud security posture?
The fire that destroyed a data center (and damaged others) at the OVHcloud facility in Strasbourg, France, on March 10-11, 2021, has raised a multitude of questions from concerned data center operators and customers around the world. Chief among these is, “What was the main cause, and could it have been prevented?”
In yet another instance of a software supply chain attack, unidentified actors hacked the official Git server of the PHP programming language and pushed unauthorized updates to insert a secret backdoor into its source code.
A security professional at Ubiquiti who helped the company respond to the two-month breach beginning in December 2020 contacted KrebsOnSecurity after raising his concerns with both Ubiquiti’s whistleblower hotline and with European data protection authorities.
GDPR is a data privacy law in the EU that mentions the use of encryption. Although not mandatory, it is yet seen as a best practice for protecting personal data. So, let us first understand what data encryption is and then understand the role of encryption in GDPR compliance.
The amount of activity in the DNS in the IETF seems to be growing every meeting. I thought that the best way to illustrate to considerably body of DNS working being undertaken at the IETF these days would be to take a snapshot of DNS activity that was reported to the DNS-related Working Group meetings at IETF 110.
please note I do not necessarily agree with anything contained in the articles linked here, nor do I necessarily support any of the sites I link to—I gather these links because I think they are interesting and present an interesting point of view worth hearing
As stated earlier, o.com along with most of the single-character .com labels were registered by Dr. Postel on December 1, 1993 as a way of reserving these domain names for a since-unrealized potential development path for the Internet’s Domain Name System (DNS).
But it strains credulity to believe random tweets can lead otherwise normal people to drive across the country and stage an insurrection. That places an undue focus on misinformation itself, rather than on the people and institutions sharing it and on the people who choose to access and believe it.
Mark Zuckerberg, Sundar Pichai and Jack Dorsey will visit with Congress today, as each has multiple times since last October, to testify about the spread of misinformation (gossip, mistakes and lies) and disinformation (propaganda) across digital platforms controlled by the companies they run.
No, you don’t. No one loves videoconferencing. No one loves finding a tidy part of their house, or brushing their hair, or having to look at their own face while they talk, or sitting through boring two-hour presentations while staring at a screen.
Google is about to fundamentally change how the web works. Sometime in 2022, most likely during the first six months, its Chrome browser will ditch the third-party cookies on which much of the digital economy is built.
As Mark Zuckerberg tries to sell Congress on Facebook’s preferred method of amending the federal law that serves as a key pillar of the internet, lawmakers must see it for what it really is: a self-serving and cynical effort to cement the company’s dominance.
In the name of combating misinformation and conspiracy theories, Microsoft has teamed with several other companies to trace content online back to its original author in what some people are calling a huge setback in data privacy.
But Belt and Road isn’t going away. China is making more rigorous lending decisions while focusing somewhat less on heavy-duty construction and more on digital technology, says a Council on Foreign Relations task force report released on March 23.
The Atlas, launched in July, contains data on more than 7,000 surveillance programs—including facial recognition, drones, and automated license plate readers—operated by thousands of local police departments and sheriffs’ offices nationwide.
Three years ago, Spectre changed the way we think about security boundaries on the web. It quickly became clear that flaws in modern processors undermined the guarantees that web browsers could make about preventing data leaks between applications.
Until the (more or less) recent explosion of new DNS RFCs (aka the ‘DNS Camel’, loosely referring to the straw that broke the camel’s back), I used to think of the DNS as something similar to chess, with a fairly simple set of rules that developed into complex systems when deployed.
As I write this, the world is probably days away from the “Great Email Robbery,” where a large number of threat actors around the globe are going to pillage and ransom the email servers of tens of thousands of businesses and local governments.
In a control experiment in which no one was distracted, the researchers observed a previously described phenomenon known as lane formation: As the two groups made contact, people arranged themselves in two or three columns.
The objective of an organization when implementing cybersecurity controls is to eliminate risk, but this oftentimes involves settling for managing risk at an acceptable level. Each organization defines what that acceptable level is depending on several factors including the environment, the criticality of function, the asset type, etc.
The most common way thieves hijack SMS messages these days involves “sim swapping,” a crime that entails bribing or tricking employees at wireless phone companies into modifying customer account information.
The botnet’s designers are using this idea to create an unblockable means of coordination, but the implications are much greater. Imagine someone using this idea to evade government censorship. Most Bitcoin mining happens in China. What if someone added a bunch of Chinese-censored Falun Gong texts to the blockchain?
Throughout our “Managing with Open Values” series, we’ve interviewed a number of managers and leaders who shared with us their experiences and practices. In this installment, I interviewed fellow Open Organization Ambassador Sam Knuth to discuss how he lets open values guide his approach to leading large teams.
With this article, the audience gets to know effective ways to ensure Kubernetes security, using must-have solutions, proven practices, and the best tools empowering building and maintaining a secure environment on the platform.
CP/M was a text-based operating system created by American programmer Gary Kildall of Digital Research in 1974. Its initials stood for “Control Program/Monitor” at first, but Digital Research changed it to the more friendly “Control Program for Microcomputers” later.
Large organizations have relied on so-called “browser isolation” services to deal with this risk for years, but these tools are often slow and clunky. As a result, many companies only require them for the most sensitive work; otherwise, employees would search for workarounds.
Even though Intel just announced its Rocket Lake-S desktop processor, eyes are already turning to what Intel has next up its sleeve: the next-generation CPU code-named Alder Lake, expected before the end of 2021.
We are on a path that will see information security transformed in the next 5-10 years. There are five trends that will enable us as an industry to improve the overall security posture and reduce the surface attack space.
In the wake of recent high-profile security incidents, I started wondering: what, generally speaking, should an organization’s security priorities be? That is, given a finite budget — and everyone’s budget is finite — what should you do first?
In this essay, we discuss Articles 22-25.3 After focusing on civil and political rights in the earlier Articles, the drafters of the UDHR turn to social security, defined as the economic, social, and cultural rights necessary for personal dignity and the free of development of one’s personality.
A company that rents out access to more than 10 million Web browsers so that clients can hide their true Internet addresses has built its network by paying browser extension makers to quietly include its code in their creations
One of the most significant effects of the COVID-19 pandemic has been a large increase in remote work. The ability to work from home has rescued the U.S. and the world from a steeper economic decline.
Security experts are now trying to alert and assist these victims before malicious hackers launch what many refer to with a mix of dread and anticipation as “Stage 2,” when the bad guys revisit all these hacked servers and seed them with ransomware or else additional hacking tools for crawling even deeper into victim networks.
There are many issues that lurk just below the surface of the DNS, but in recent years one topic has been very prominent, namely privacy. You see the DNS is a precursor to almost everything we do on the Internet. And this is valuable information.
Since the early 2000s, the global debate about Internet Governance did have its ups and downs. We did see the establishment of ICANN, the UN World Summit on the Information Society (WSIS), the making of the Internet Governance Forum (IGF), and the failure of the World Conference on International Telecommunication (WCIT).
Here’s a brief timeline of what we know leading up to last week’s mass-hack, when hundreds of thousands of Microsoft Exchange Server systems got compromised and seeded with a powerful backdoor Trojan horse program.
We have a bad case of the silicon shakes and a worsening deficiency in iron here at The Next Platform, but the good news is that new CPU processors from AMD and Intel are imminent, and more processors are expected later this year from IBM and Ampere Computing, too. There will be others.
The company’s custom-built system for storing and managing the hundreds of billions of user content items (with multiple petabytes uploaded daily) has had to stand the test of time, performance, and cost pressures
Most people are aware of the rising price of Bitcoin. Despite the fact that most people are unaware of how to transact in it, and few merchants take it as a form of currency, Bitcoin is becoming an increasingly popular investment. As interest in Bitcoin grows, a few people are starting to take notice of the startling energy costs associated with Bitcoin transactions.
On March 12, 2021, the Conseil d’Etat — France’s highest administrative court — ruled that personal data on a platform used to book COVID-19 vaccinations, managed by Doctolib and hosted by Amazon Web Services, was sufficiently protected under the EU General Data Protection Regulation because sufficient safeguards, both legal and technical, were put in place in case of an access request from U.S. authorities.
With every passing year, as AMD first talked about its plans to re-enter the server processor arena and give Intel some real, much needed, and very direct competition and then delivered again and again on its processor roadmap, it has gotten easier and easier to justify spending at least some of the server CPU budget with Intel’s archrival in the X86 computing arena.
Your employer is nominally based in New York City, but thanks to the pandemic, you didn’t even cross the Hudson River last year. So how is it that New York claims you owe it a pile of cash for state taxes?
In risk-based test management, you find the greatest market threats (that would have a detrimental effect on the enterprise as defined by the consumer) early in the development cycle and then you can counter them by taking preventive steps.
SpaceX and Dish Network are fighting at the Federal Communications Commission over Dish’s attempt to block a key designation that SpaceX’s Starlink division needs in order to get FCC broadband funding.
The blog talks about the solvable challenges of automating the process of performing huge volumes of fiber cross-connects in data centers. Doing cross-connects with robots would allow for fiber connections to be made 24/7 as needed while improving accuracy.
Fortunately, organizations can help to protect their cardholder environments against ransomware and other digital threats by achieving compliance with the Payment Card Industry Data Security Standard (PCI DSS).
A look into the indictment that was unsealed as part of Marcus’s arrest provides the first clues. In the copy dated to August 2017, the same month as the arrest, the FBI leveled six charges against Marcus and a partner whose name was redacted.
2020 presented an enormous learning curve for network operators. Demands for Internet usage surged at a time when lockdowns, travel restrictions and stay-at-home orders posed new logistical challenges.
Exactly a month after patching an actively exploited zero-day flaw in Chrome, Google today rolled out fixes for yet another zero-day vulnerability in the world’s most popular web browser that it says is being abused in the wild.
Microsoft has released emergency patches to address four previously undisclosed security flaws in Exchange Server that it says are being actively exploited by a new Chinese state-sponsored threat actor with the goal of perpetrating data theft.
This is how the squeeze worked: A few large hedge funds had “shorted” GameStop. That means that they had borrowed the stock, with the intention of returning it when the share price moved lower, as they expected it would, leaving them with a profit.
A new canvassing of experts in technology, communications and social change by Pew Research Center and Elon University’s Imagining the Internet Center finds that many expect similar impacts to emerge from the COVID-19 outbreak.
A famed Silicon Valley dictum is to ask for forgiveness, not permission. Breaking the law has had no consequences, and policymakers have not been too exercised to create new laws for Big Tech to follow.
Today, the Supreme Court of the United Kingdom ruled on an important question as to whether certain drivers who work with Uber are entitled to certain protections under British statutes. The court found that they were.
No one should mourn the death of the cookie as we know it. For more than two decades, the third-party cookie has been the lynchpin in a shadowy, seedy, multi-billion dollar advertising-surveillance industry on the Web; phasing out tracking cookies and other persistent third-party identifiers is long overdue.
The multi-pronged attempt by state Attorneys General, the Department of Justice, and the Federal Trade Commission to find Google and Facebook liable for violating antitrust law may result in breaking up these giant companies. But in order for any of this to cause lasting change, we need to look to the not-so-recent past.
Last Friday, the floodgates opened. Thousands of Uber drivers flocked to sue the ride-hailing company for back pay and benefits after the Supreme Court ruled that it must now classify drivers on its platform as workers.
Google and Facebook make a lot of noise about how their main services are free to use. And it’s true, they are. But what they don’t highlight is their role in making almost everything else we consume online more expensive.
To stand out from the competition and get into classrooms, curriculum developers, policymakers, and advocacy groups have begun to scam the education market by forsaking common-sense STEM principles in pursuit of colorful toys and Critical Race Theory dogma.
The Indian government’s recent Internet shutdown during farmer protests impacted over 50 million residents. It is a stark warning of the danger of tampering with the foundations that make the Internet work for everyone.
