When passwords are not enough

Published

on

An identity theft epidemic looms in South Africa and passwords will not be enough to protect you. But there is a solution, writes ARTHUR GOLDSTUCK.

South Africans have to brace themselves for an identity theft epidemic, after a website exposed 60-million South African identity numbers, along with extensive personal details (see http://bit.ly/SAbreach).

Suddenly, it is not enough to choose complicated, hard-to-guess passwords for online services like Internet banking, email, backup sites and cellphone services. In many cases, one merely has to confirm a range of personal details – exactly like those exposed in the breach – to change a password and gain access to a website containing financially sensitive information.

It is for this very reason that information security experts have for many years recommended something called two-factor authentication (2FA). It means that, to access a site or service, one needs a physical form of authentication as well as digital verification like user names and passwords.

The typical solution is to use one’s smartphone, usually via a one-time password e-mailed or sent by SMS. While this meets the technical definition of two-factor authentication, it is useless if identity theft has been used to have a new SIM card issued with your number.

Enter U2F, or Universal Second Factor. Jointly developed in 2012 by Google and a company called Yubico, it was adopted a year later by an industry body, the FIDO (“Fast IDentity Online”) Alliance, as a standard for two-factor authentication.

According to Yubico, it “enables Internet users to securely access any number of online services, with one single device, instantly and with no drivers, or client software needed”. You still need separate passwords for each site, but a separate device validates them.

The main problem with the solution in South Africa has been the absence of suitable U2F devices. That, in turn, has largely been a factor of service providers like banks not embracing the standard.

But now, the game has changed, First, a growing number of major international organisations have built it into their security options, with Google, Facebook and Dropbox, among other, all having it as an option.

Secondly, and most important, a South African company has built the first home-grown U2F-compliant solution.

It’s called SOLID wekKey, and it looks like a small USB flash drive. It  secures several hundred passwords with a single overarching password. A small, downloadable password manager application allows the user to transform all these passwords into strong passwords that are almost impossible to guess or crack.

It was developed by Ansys, a South African company based in Centurion. Ansys has made a name for itself manufacturing custom security products for clients, ranging from small businesses to large enterprises, across the defence, aerospace, industrial and telecommunications sectors. With webKey, it is venturing into designing and marketing its own products for the consumer market.

“The general public struggles with basic account security,” says Ansys CEO Teddy Daka. “Year after year, we see that easy to crack passwords such as ‘123456’ or ‘password’ are still in common use, and individuals rely on just one or two memorable passwords or passphrases to protect all their online accounts.”

He reminds the public that, while security experts recommend the use of long passwords made up of uncommon phrases, and that every account must be protected with a unique password, people tend to use the same simple credentials all the time. As this writer has pointed out many times, when a user name and password is stolen from one site, it can often be used across multiple services.

The real issue is that people tend to compromise security for the sake of simplicity. The more secure a solution, usually, the more complex, and therefore the less popular. However, we have entered an era when hackers are going after the big fish and the small alike. When it is as easy to break into a million small accounts as one big one, no one remains safe. That means the simple solutions are no longer secure enough.

“People use easy to remember passwords because they choose convenience over security,” says Daka. “This shouldn’t come as a surprise. We shouldn’t expect people to remember passwords that are made up of 25 random characters for an account they need to access every day.”

However, products like SOLID webKey do the remembering for the user. Yes, you can build complex pass phrases into a password locker on your smartphone, but the locker is as vulnerable as the phone itself. Keep the password on a separate device, and one extra barrier has been placed between the hacker and your peace of mind.

How does it work?

SOLID webKey uses a combination of physical password vault, contained on a USB device, and a small industry-standard software application called KeePass.

The full name of the application, KeePass Password Safe, sums up its role perfectly: it is the equivalent of placing your valuables in an industrial-strength safe. Of course, as Hollywood teaches us, no safe is completely foolproof, but this kind of solution gives the user a chance against both random hackers and the professionals looking for easy targets.

Typically, hackers would use malware, or infected software, delivered via cunning “phishing” email and other attacks, to steal passwords. The SOLID webKey guards against this by requiring a physical tap of the USB device before passwords can be accessed. Because the password is never typed in, but delivered via a hardware “token”, it can’t easily be intercepted.

This is the basis of  both two-factor authentication (2FA) and the Universal Two-Factor (U2F) standard promoted by the FIDO Alliance.

The main obstacle to the wider uptake of U2F is the fact that it remains a mystery to most consumers, and even services like Gmail and Facebook – which come under regular, sustained attack – do not make a special effort to highlight the option. However, as the cyber war intensifies, U2F is expected to move to the front and centre of such sites’ efforts to protect their users.

“Two-factor authentication is rapidly becoming the norm, and is a proven way to secure accounts,” says Daka. “Through SOLID webKey, we hope to make it easier to use and therefore more popular with South Africans who want the best in online security.”

Prepare your cam to capture the Blood Moon

On 27 July 2018, South Africans can witness a total lunar eclipse, as the earth’s shadow completely covers the moon.

Published

on

Also known as a blood or red moon, a total lunar eclipse is the most dramatic of all lunar eclipses and presents an exciting photographic opportunity for any aspiring photographer or would-be astronomers.

“A lunar eclipse is a rare cosmic sight. For centuries these events have inspired wonder, interest and sometimes fear amongst observers. Of course, if you are lucky to be around when one occurs, you would want to capture it all on camera,” says Dana Eitzen, Corporate and Marketing Communications Executive at Canon South Africa.

Canon ambassador and acclaimed landscape photographer David Noton has provided his top tips to keep in mind when photographing this occasion.   In South Africa, the eclipse will be visible from about 19h14 on Friday, 27 July until 01h28 on the Saturday morning. The lunar eclipse will see the light from the sun blocked by the earth as it passes in front of the moon. The moon will turn red because of an effect known as Rayleigh Scattering, where bands of green and violet light become filtered through the atmosphere.

A partial eclipse will begin at 20h24 when the moon will start to turn red. The total eclipse begins at about 21h30 when the moon is completely red. The eclipse reaches its maximum at 22h21 when the moon is closest to the centre of the shadow.

David Noton advises:

  1. Download the right apps to be in-the-know

The sun’s position in the sky at any given time of day varies massively with latitude and season. That is not the case with the moon as its passage through the heavens is governed by its complex elliptical orbit of the earth. That orbit results in monthly, rather than seasonal variations, as the moon moves through its lunar cycle. The result is big differences in the timing of its appearance and its trajectory through the sky. Luckily, we no longer need to rely on weight tables to consult the behaviour of the moon, we can simply download an app on to our phone. The Photographer’s Ephemeris is useful for giving moonrise and moonset times, bearings and phases; while the Photopills app gives comprehensive information on the position of the moon in our sky.  Armed with these two apps, I’m planning to shoot the Blood Moon rising in Dorset, England. I’m aiming to capture the moon within the first fifteen minutes of moonrise so I can catch it low in the sky and juxtapose it against an object on the horizon line for scale – this could be as simple as a tree on a hill.

 

  1. Invest in a lens with optimal zoom  

On the 27th July, one of the key challenges we’ll face is shooting the moon large in the frame so we can see every crater on the asteroid pockmarked surface. It’s a task normally reserved for astronomers with super powerful telescopes, but if you’ve got a long telephoto lens on a full frame DSLR with around 600 mm of focal length, it can be done, depending on the composition. I will be using the Canon EOS 5D Mark IV with an EF 200-400mm f/4L IS USM Ext. 1.4 x lens.

  1. Use a tripod to capture the intimate details

As you frame up your shot, one thing will become immediately apparent; lunar tracking is incredibly challenging as the moon moves through the sky surprisingly quickly. As you’ll be using a long lens for this shoot, it’s important to invest in a sturdy tripod to help capture the best possible image. Although it will be tempting to take the shot by hand, it’s important to remember that your subject is over 384,000km away from you and even with a high shutter speed, the slightest of movements will become exaggerated.

  1. Integrate the moon into your landscape

Whilst images of the moon large in the frame can be beautifully detailed, they are essentially astronomical in their appeal. Personally, I’m far more drawn to using the lunar allure as an element in my landscapes, or using the moonlight as a light source. The latter is difficult, as the amount of light the moon reflects is tiny, whilst the lunar surface is so bright by comparison. Up to now, night photography meant long, long exposures but with cameras such as the Canon EOS-1D X Mark II and the Canon EOS 5D Mark IV now capable of astonishing low light performance, a whole new nocturnal world of opportunities has been opened to photographers.

  1. Master the shutter speed for your subject 

The most evocative and genuine use of the moon in landscape portraits results from situations when the light on the moon balances with the twilight in the surrounding sky. Such images have a subtle appeal, mood and believability.  By definition, any scene incorporating a medium or wide-angle view is going to render the moon as a tiny pin prick of light, but its presence will still be felt. Our eyes naturally gravitate to it, however insignificant it may seem. Of course, the issue of shutter speed is always there; too slow an exposure and all we’ll see is an unsightly lunar streak, even with a wide-angle lens.

 

On a clear night, mastering the shutter speed of your camera is integral to capturing the moon – exposing at 1/250 sec @ f8 ISO 100 (depending on focal length) is what you’ll need to stop the motion from blurring and if you are to get the technique right, with the high quality of cameras such as the Canon EOS 5DS R, you might even be able to see the twelve cameras that were left up there by NASA in the 60’s!

How Africa can embrace AI

Currently, no African country is among the top 10 countries expected to benefit most from AI and automation. But, the continent has the potential to catch up with the rest of world if we act fast, says ZOAIB HOOSEN, Microsoft Managing Director.

To play catch up, we must take advantage of our best and most powerful resource – our human capital. According to a report by the World Economic Forum (WEF), more than 60 percent of the population in sub-Saharan Africa is under the age of 25.

These are the people who are poised to create a future where humans and AI can work together for the good of society. In fact, the most recent WEF Global Shapers survey found that almost 80 percent of youth believe technology like AI is creating jobs rather than destroying them.

Staying ahead of the trends to stay employed

AI developments are expected to impact existing jobs, as AI can replicate certain activities at greater speed and scale. In some areas, AI could learn faster than humans, if not yet as deeply.

According to Gartner, while AI will improve the productivity of many jobs and create millions more new positions, it could impact many others. The simpler and less creative the job, the earlier, a bot for example, could replace it.

It’s important to stay ahead of the trends and find opportunities to expand our knowledge and skills while learning how to work more closely and symbiotically with technology.

Another global study by Accenture, found that the adoption of AI will create several new job categories requiring important and yet surprising skills. These include trainers, who are tasked with teaching AI systems how to perform; explainers, who bridge the gap between technologist and business leader; and sustainers, who ensure that AI systems are operating as designed.

It’s clear that successfully integrating human intelligence with AI, so they co-exist in a two-way learning relationship, will become more critical than ever.

Combining STEM with the arts

Young people have a leg up on those already in the working world because they can easily develop the necessary skills for these new roles. It’s therefore essential that our education system constantly evolves to equip youth with the right skills and way of thinking to be successful in jobs that may not even exist yet.

As the division of tasks between man and machine changes, we must re-evaluate the type of knowledge and skills imparted to future generations.

For example, technical skills will be required to design and implement AI systems, but interpersonal skills, creativity and emotional intelligence will also become crucial in giving humans an advantage over machines.

“At one level, AI will require that even more people specialise in digital skills and data science. But skilling-up for an AI-powered world involves more than science, technology, engineering and math. As computers behave more like humans, the social sciences and humanities will become even more important. Languages, art, history, economics, ethics, philosophy, psychology and human development courses can teach critical, philosophical and ethics-based skills that will be instrumental in the development and management of AI solutions.” This is according to Microsoft president, Brad Smith, and EVP of AI and research, Harry Shum, who recently authored the book “The Future Computed”, which primarily deals with AI and its role in society.

Interestingly, institutions like Stanford University are already implementing this forward-thinking approach. The university offers a programme called CS+X, which integrates its computer science degree with humanities degrees, resulting in a Bachelor of Arts and Science qualification.

Revisiting laws and regulation

For this type of evolution to happen, the onus is on policy makers to revisit current laws and even bring in new regulations. Policy makers need to identify the groups most at risk of losing their jobs and create strategies to reintegrate them into the economy.

Simultaneously, though AI could be hugely beneficial in areas such as curbing poor access to healthcare and improving diagnoses for example, physicians may avoid using this technology for fear of malpractice. To avoid this, we need regulation that closes the gap between the pace of technological change and that of regulatory response. It will also become essential to develop a code of ethics for this new ecosystem.

Preparing for the future

With the recent convergence of a transformative set of technologies, economies are entering a period in which AI has the potential overcome physical limitations and open up new sources of value and growth.

To avoid missing out on this opportunity, policy makers and business leaders must prepare for, and work toward, a future with AI. We must do so not with the idea that AI is simply another productivity enhancer. Rather, we must see AI as the tool that can transform our thinking about how growth is created.

It comes down to a choice of our people and economies being part of the technological disruption, or being left behind.
