4 no-brainer online security measures we need to start practicing now
We're blissfully ignorant of how we put ourselves at risk online.
- According to the 2019 Official Annual Cybercrime Report, businesses fall for ransomware attacks every 14 seconds.
- Many people ignore standard security practices that significantly reduce their chances of being attacked, such as disabling their computer's microphone and camera.
- Establishing better cyber security practices is a matter of unlearning bad habits, and creating better ones.
The sheer number of massive data breaches and known security vulnerabilities online today should be enough to scare us into better data safety practices. However, though these issues seem to consistently elicit gasps and condemnations by talking heads and private users, little else is done. It's not about turning office and personal computers into Fort Knox, really, it's about using common sense and exercising caution.
According to the 2019 Official Annual Cybercrime Report, businesses fall for ransomware attacks every 14 seconds. Cybercrime is also on the rise, with some estimates putting the cost of online crimes at roughly $6 trillion by 2021. In this increasingly risky landscape, it makes sense to invest heavily in antivirus, anti-malware, and overall protection tools. However, these applications can only take you so far.
At some point, the problem isn't that hackers are too smart for us, but that we, in a false sense of security, believe we can let our guard down, which leads us to ignore standard security practices that significantly reduce chances of our being attacked. Here are some no-brainer security steps that we constantly overlook but should start keeping in mind.
Browsing the web via VPN
While it may seem like an endless amusement park with everything you've ever wanted to find, the internet is a much darker than we'd like to imagine. Although it is undoubtedly a great tool and has significantly enhanced quality of life the world over, the internet also means our personal data is now exposed every time we browse the web or open an application online. Often, sites and bodies we see as the "safest" are often themselves invaders of our privacy such as internet service providers, governments, and giant tech companies.
Connecting to an unknown network can be dangerous — something nearly 92 percent of those who use public WiFi networks ignore. Undeniably, many have started to limit their activity online as their concerns about privacy (rightfully) grow. Yet, many people still happily browse the web without a care and continue to leave trails of data everywhere, creating noteworthy problems when their information is scanned and compromised.
According to Harold Li, Vice President at ExpressVPN: "In an era when we conduct the most crucial and sensitive parts of our lives online, a VPN is a critical tool for protecting both digital privacy and security. They increase your anonymity online, shield your online activity from monitoring by ISPs and governments, and defend your data from hackers on shared networks such as public Wi-Fi." Even so, most of us continue to neglect VPNs. In fact, according to VPN Mentor, only 5 percent of internet users in the U.S. have a VPN.
Protecting Google docs
As we become increasingly reliant on the cloud, one of the first things we've migrated is our ability to do work. McAfee's 2019 Cloud Adoption and Risk Report found that for the past six years running, the "file sharing and collaboration services" category — services such as Google Docs — has been the leading driver of cloud use in business, accounting for nearly 21 percent of services in use at the average company.
According to the study, today, some 83 percent of organizations store sensitive data in the cloud, and about 8 percent of all cloud-shared documents include sensitive information. Moreover, we're sharing these files more than we used to, with significant year-over-year rises in documents set for open access to "anyone with a link."
This is problematic for two reasons. On one hand, the ease with which we can share documents increases the likelihood that they will be intercepted. On the other, as user bases stratify around services they use, SaaS platforms gain access to sensitive corporate assets unbeknownst to even the IT team. This is what's known as "shadow IT."
In remarks to Techopedia, Uri Haramati, the CEO of SaaS management platform company Torii , noted that "Considering the rampant threat of cyberattacks, security risks are definitely something companies have to be wary of."
On the other hand, "The fact that they are trying out new tools, means that they want to be better at their work," according to Haramati. "Why should management dampen such a positive attitude? Instead, leaders should value their employees' drive to be better and find out how their existing processes can be improved upon."
Disabling your microphone and camera
Recently, video conferencing service Zoom was revealed to have major flaws that allow hackers to theoretically take over unsuspecting users' webcams with a single URL. This may seem like a less threatening incident than having data stolen, but it can be just as damaging. A malicious third party with unfettered access to your webcam can discern much about your personal habits and can potentially witness and record damaging or embarrassing situations. In the U.K., for instance, there have been recorded incidents of hackers capturing these moments and threatening to upload them to social media unless a ransom is paid.
The problem is similar with microphones, which can be used to track your communications even when your devices are "off." Most A.I.-based assistants today, for instance (such as Siri, Alexa, and Google Home) are constantly listening, and companies have people on the other side listening to these recordings, as was discovered recently with Siri. Simply turning off your microphone manually can give you significant protection.
Using Encrypted Communications
It may sound straight out of a James Bond movie, but encryption is quickly becoming one of the most important technology fields in our digitized world. Even with a VPN and robust protection, it's still not impossible for someone to access our communications while they're in transit between us and the recipients. In fact, as our messaging applications expand in number and importance, governments, law enforcement and nefarious actors' interest in them is rising.
Many services do offer powerful encryption tools and features, but people often remain on the most popular chat apps because of convenience and familiarity. Facebook Messenger remains one of the most popular tools (despite belonging to a decidedly anti-privacy corporation), while Chinese apps like WeChat and Tencent's QQ Mobile are also main players despite the fact that they're both heavily monitored by the Chinese Government.
Facebook's Messenger, for instance, only offers optional end-to-end encryption (even though WhatsApp, which Facebook also owns, provides E2E by default). This doesn't even account for emails, which remain the most popular online communication method. Even when sending sensitive data, we're more than happy to send it via Gmail or Yahoo! and completely ignore the fact that there is little we can do once those emails leave our inboxes to protect the information we've shared.
Establishing better cyber security practices doesn't require a computer science degree and a military budget. What it needs is attention to detail, unlearning bad habits, and creating new ones. As the number of vectors available to hackers, scammers, data miners and governments continue to expand, it won't be big things that cause breaches, but rather something as small as leaving a webcam on, forgetting a password, or sending a compromising email without considering who may view it.
New anthropological research suggests our ancestors enjoyed long slumbers.
- Neanderthal bone fragments discovered in northern Spain mimic hibernating animals like cave bears.
- Thousands of bone fragments, dating back 400,000 years, were discovered in this "pit of bones" 30 years ago.
- The researchers speculate that this physiological function, if true, could prepare us for extended space travel.
Humans have a terrible sense of time. We think in moments, not eons, which accounts for a number of people that still don't believe in evolutionary theory: we simply can't imagine ourselves any differently than we are today.
Thankfully, scientists and researchers have vast imaginations. Their findings often depend on creative problem-solving. Anthropologists are especially adept at this skill, as their job entails imagining a prehistoric world in which humans and our forebears were very different creatures.
A new paper, published in the journal L'Anthropologie, takes a hard look at ancient bone health and arrives at a surprising conclusion: Neanderthals (and possibly early humans) might have endured long, harsh winters by hibernating.
Adaptability is the key to survival. Certain endotherms evolved the ability to depress their metabolism for months at a time; their body temperature and metabolic rate lowered while their breathing and heart rate dropped to nearly imperceptible levels. This handy technique solved a serious resource management problem, as food supplies were notoriously scarce during the frozen months.
While today the wellness industry eschews fat, it has long had an essential evolutionary function: it keeps us alive during times of food scarcity. As autumn months pass, large mammals become hyperphagic (experiencing intense hunger followed by overeating) and store nutrients in fat deposits; smaller animals bury food nearby for when they need a snack. This strategy is critical as hibernating animals can lose over a quarter of their body weight during winter.
For this paper, Antonis Bartsiokas and Juan-Luis Arsuaga, both in the Department of History and Ethnology at Democritus University of Thrace, scoured through remains of a "pit of bones" in northern Spain. In 1976, archaeologists found a 50-foot shaft leading down into a cave in Atapuerca, where thousands of bone fragments have since been discovered. Dating back 400,000 years—some of the fragments may be as old as 600,000 years—researchers believe the bodies were intentionally buried in this cave.

While the fragments have been well studied in the intervening decades, Arsuaga (who led an early excavation in Atapuerca) and Bartsiokas noticed something odd about the bones: they displayed signs of seasonal variations. These proto-humans appear to have experienced annual bone growth disruption, which is indicative of hibernating species.
In fact, the remains of cave bears were also found in this pit, increasing the likelihood that the burial site was reserved for species that shared common features. This could be the result of a dearth of food for bears and Neanderthals alike. The researchers write that modern northerners don't need to sleep for months at a time; an abundance of fish and reindeer didn't exist in Spain, as they do in the Arctic. They write,
"The aridification of Iberia then could not have provided enough fat-rich food for the people of Sima during the harsh winter—making them resort to cave hibernation."
The notion of hibernating humans is appealing, especially to those in cold climates, but some experts don't want to put the cart before the horse. Large mammals don't engage in textbook hibernation; their deep sleep is known as a "torpor." Even then, the demands of human-sized brains could have been too large for extended periods of slumber.
Still, as we continually discover our animalistic origins to better understand how we evolved, the researchers note the potential value of this research.
"The present work provides an innovative approach to the physiological mechanisms of metabolism in early humans that could help determine the life cycle and physiology of extinct human species."
Bartsiokas speculates that this ancient mechanism could be coopted for space travel in the future. If the notion of hibernating humans sounds far-fetched, the idea has been contemplated for years, as NASA began funding research on this topic in 2014. As the saying goes, everything old is new again.

It is impossible for science to arrive at ultimate truths, but functional truths are good enough.
- What is truth? This is a very tricky question, trickier than many would like to admit.
- Science does arrive at what we can call functional truth, that is, when it focuses on what something does as opposed to what something is. We know how gravity operates, but not what gravity is, a notion that has changed over time and will probably change again.
- The conclusion is that there are not absolute final truths, only functional truths that are agreed upon by consensus. The essential difference is that scientific truths are agreed upon by factual evidence, while most other truths are based on belief.
Does science tell the truth? The answer to this question is not as simple as it seems, and my 13.8 colleague Adam Frank took a look at it in his article about the complementarity of knowledge. There are many levels of complexity to what truth is or means to a person or a community. Why?
First, "truth" itself is hard to define or even to identify. How do you know for sure that someone is telling you the truth? Do you always tell the truth? In groups, what may be considered true to a culture with a given set of moral values may not be true in another. Examples are easy to come by: the death penalty, abortion rights, animal rights, environmentalism, the ethics of owning weapons, etc.
At the level of human relations, truth is very convoluted. Living in an age where fake news has taken center stage only corroborates this obvious fact. However, not knowing how to differentiate between what is true and what is not leads to fear, insecurity, and ultimately, to what could be called worldview servitude — the subservient adherence to a worldview proposed by someone in power. The results, as the history of the 20th century has shown extensively, can be catastrophic.
Proclamations of final or absolute truths, even in science, shouldn't be trusted.
The goal of science, at least on paper, is to arrive at the truth without recourse to any belief or moral system. Science aims to go beyond the human mess so as to be value-free. The premise here is that Nature doesn't have a moral dimension, and that the goal of science is to describe Nature the best possible way, to arrive at something we could call the "absolute truth." The approach is a typical heir to the Enlightenment notion that it is possible to take human complications out of the equation and have an absolute objective view of the world. However, this is a tall order.
It is tempting to believe that science is the best pathway to truth because, to a spectacular extent, science does triumph at many levels. You trust driving your car because the laws of mechanics and thermodynamics work. NASA scientists and engineers just managed to have the Ingenuity Mars Helicopter — the first man-made device to fly over another planet — hover above the Martian surface all by itself.
We can use the laws of physics to describe the results of countless experiments to amazing levels of accuracy, from the magnetic properties of materials to the position of your car in traffic using GPS locators. In this restricted sense, science does tell the truth. It may not be the absolute truth about Nature, but it's certainly a kind of pragmatic, functional truth at which the scientific community arrives by consensus based on the shared testing of hypotheses and results.
What is truth?

But at a deeper level of scrutiny, the meaning of truth becomes intangible, and we must agree with the pre-Socratic philosopher Democritus who declared, around 400 years BCE, that "truth is in the depths." (Incidentally, Democritus predicted the existence of the atom, something that certainly exists in the depths.)
A look at a dictionary reinforces this view. "Truth: the quality of being true." Now, that's a very circular definition. How do we know what is true? A second definition: "Truth: a fact or belief that is accepted as true." Acceptance is key here. A belief may be accepted to be true, as is the case with religious faith. There is no need for evidence to justify a belief. But note that a fact as well can be accepted as true, even if belief and facts are very different things. This illustrates how the scientific community arrives at a consensus of what is true by acceptance. Sufficient factual evidence supports that a statement is true. (Note that what defines sufficient factual evidence is also accepted by consensus.) At least until we learn more.
Take the example of gravity. We know that an object in free fall will hit the ground, and we can calculate when it does using Galileo's law of free fall (in the absence of friction). This is an example of "functional truth." If you drop one million rocks from the same height, the same law will apply every time, corroborating the factual acceptance of a functional truth, that all objects fall to the ground at the same rate irrespective of their mass (in the absence of friction).
But what if we ask, "What is gravity?" That's an ontological question about what gravity is and not what it does. And here things get trickier. To Galileo, it was an acceleration downward; to Newton a force between two or more massive bodies inversely proportional to the square of the distance between them; to Einstein the curvature of spacetime due to the presence of mass and/or energy. Does Einstein have the final word? Probably not.
Is there an ultimate scientific truth?
Final or absolute scientific truths assume that what we know of Nature can be final, that human knowledge can make absolute proclamations. But we know that this can't really work, for the very nature of scientific knowledge is that it is incomplete and contingent on the accuracy and depth with which we measure Nature with our instruments. The more accuracy and depth our measurements gain, the more they are able to expose the cracks in our current theories, as I illustrated last week with the muon magnetic moment experiments.
So, we must agree with Democritus, that truth is indeed in the depths and that proclamations of final or absolute truths, even in science, shouldn't be trusted. Fortunately, for all practical purposes — flying airplanes or spaceships, measuring the properties of a particle, the rates of chemical reactions, the efficacy of vaccines, or the blood flow in your brain — functional truths do well enough.
Using urinals, psychological collages, and animated furniture to shock us into reality.
- Dada is a provocative and surreal art movement born out of the madness of World War I.
- Tzara, a key Dada theorist, says Dada seeks "to confuse and upset, to shake and jolt" people from their comfort zones.
- Dada, as all avant-garde art, faces a key problem in how to stay true to its philosophy.
In a world gone mad, what can the few sane people left do? What can someone say when there are no words that seem up to the job? How can anyone hope to express ideas so terrible when doing so will only reduce those ideas?
These are some of the things that inspired the Dada movement, and in its absurd, surreal, and chaotic nonsense, we find the voice of the voiceless.
The origin of Dadaism
Dada was a response to the madness of World War I. Reasonable, intelligent, and sensitive people looked at the blood and mud graveyards of the trenches and wondered how any meaning or goodness could ever be found again. How can someone make sense of a world where millions of young, happy, hopeful men were scythed down in a spray of bullets? How could life go back to normal when returning soldiers, blinded and disfigured from gas, lay homeless in the streets? Out of this awful revulsion, there came one bitter voice, and it said: "Everything is nonsense."
Dada is the art of the nihilist. It smashes accepted wisdom, challenges norms and values, and offends, upsets, and provokes us to re-examine everything.
And so, the Dada movement expressed itself in absurdity. Tzara, the closest you get to a Dadaist philosopher, put it like this: "Like everything in life, Dada is useless. Dada is without pretension, as life should be." Dada rejects all systems, all philosophy, all definite answers, and all truth. It is the living embrace of contradictions and nonsense. It seeks "to confuse and upset people, to shake and jolt". It aims to shout down the "shamefaced sex of comfortable compromise and good manners," when actually "everything happens in a completely idiotic way."
In short, Dada is a response to the world when all the usual methods have broken down. It's the recognition that dinner party conversations, Hollywood blockbusters, and Silicon Valley are not how life actually is. This is a false reality and order, like some kind of veneer.
The Dada response to life is to embrace the personal and passionate madness of it all, where "the intensity of a personality is transposed directly, clearly into the work." It's to recognize the unique position of an artist, who can convey ideas and feelings in a way that goes beyond normal understanding. Art goes straight to the soul, but the intensity of it all can be hard to "enjoy" in the strictest sense.
Where is this Dada?
For instance, Dada is seen in the poems of Hugo Ball who wrote in meaningless foreign-sounding words. It's in Hausmann, who wrote works in disconnected phonemes. It's found in Duchamp's iconoclastic "Fountain" that sought to question what art or an artist really meant. It's in Hans Richter's short film "Ghost before Breakfast," which has an incoherent montage of images, loosely connected by the theme of inanimate objects in revolt. And, it's in Kurt Schwitters' "psychological collages" which present fragments of objects, juxtaposed together.
Dada is intended to shock. It's an artistic jolt asking, or demanding, that the viewers reorient themselves in some way. It is designed to make us feel uncomfortable and does not make for easy appreciation. It's only when we're thrown so drastically outside of our comfort zone in this way that Dada asks us to question how things are. It shakes us out of a conformist stupor to look afresh at things.
The paradox of Dadaism
Of course, like all avant-garde art, Dada needs to address one major problem: how do you stay so provocative, so radical, and so anti-establishment when you also seek success? How can maverick rebels stay so as they get a mortgage and want a good school for their kids? The problem is that young, inventive, and idealistic artists are inevitably sucked into the world of profit and commodity.
As Grayson Perry, a British modern artist, wrote: "What starts as a creative revolt soon becomes co-opted as the latest way to make money," and what was once fresh and challenging "falls away to reveal a predatory capitalist robot." With Dada, how long can someone actually live in a world of nonsense and nihilistic absurdity?
But there will always be new blood to keep movements like Dada going. As the revolutionaries of yesterday become the rich mansion-owners of today, there will be hot, young things to come and take up the mantle. There will always be something to challenge and questions to be asked. So, art movements like Dada will always be in the vanguard.
Dada is the art of the nihilist. It smashes accepted wisdom, challenges norms and values, and offends, upsets, and provokes us to re-examine everything. It's an absurd art form that reflects the reality it perceives — that life is nothing more than a dissonant patchwork of egos floating in an abyss of nothing.
