When it comes to security in any sector, prevention is better than cure. DOROS HADJIZENONOS, Country Manager of Check Point, discusses the latest threats to the healthcare industry and how the industry can increase its protection against cyber-attacks.
The healthcare industry, arguably one of the most technologically advanced considering the gadgets and devices now used to monitor health statistics and perform medical procedures, is ironically among the most ‘unhealthy’ when it comes to network security.
Delegates attending the recent Healthcare Innovation Summit were told that medical records are being increasingly targeted by cybercriminals – data from the US showed that 89% of healthcare institutions suffered a security breach and were twice more likely to be targeted than other organisations.
Healthcare record theft increased a shocking 1100% this year with more than 100 million records compromised worldwide. The biggest threat, says KPMG, comes from external attackers – at 65% – while malware tops the list of information security concerns.
But why is an industry with the technological ability to perform surgery on patients in other countries so sick when it comes to protecting information?
The answer is multi-faceted:
- Valuable data. Data collected and stored by hospitals and other organisations, such as medical aid schemes, is up to ten times more valuable to cybercriminals than credit card information. This is due to the sheer volume of information gathered about individuals – and the fact that we’re seeing an increased shift to digital medical records – which makes it easy to commit fraud and identity theft. Given the value of this data on the black market, cyber-attacks are becoming ever more sophisticated in their attempts to hack healthcare institutions.
- Ageing infrastructure. Hospitals are melting pots of outdated infrastructure, old operating systems and state-of-the-art medical technology, all communicating over the same networks. Often, hospitals take an ‘if it’s not broken, don’t fix it’ approach to technology, so devices may not be patched with the latest software versions, for example. The problem, however, is that the system is very much broken. KPMG found that, in terms of technical capabilities, the healthcare industry is behind other industries when it comes to protecting infrastructure and information.
- Complex networks. The fact that so many different people, devices and departments need to access a medical institution’s records forces them to adopt open networks. Add to this the increasing number of Internet of Things and the myriad Internet-connected gadgets connecting to the network and it becomes difficult to secure and even more vulnerable to attack.
- No budget. Security spending in the healthcare industry is at times as little as one-tenth of what other industries spend. When it comes to technology spending, a new MRI machine will likely win the budget lottery over security software.
- Easy targets. Ransomware is one of the biggest methods used by cybercriminals to gain access to medical data. This involves ‘kidnapping’ the data and only releasing it once the hospital pays a ransom. Because medical organisations are generally dealing with crises, they need urgent access to their data and are more willing to pay the ransom to get back up and running as quickly as possible. Cybercriminals know this and are exploiting it.
- Lack of understanding and awareness. Although medical institutions are becoming more technologically centric, that’s not to say they’re focusing on technology and there’s a lack of understanding of what’s going on when it comes to cyber security. There needs to be an increased understanding of how to defend against attacks like ransomware, coupled with a bigger focus on educating staff and users on how to spot phishing attacks – people are, after all, the weakest link in the security chain.
Prevention is better than cure
It sounds clichéd but, when it comes to security in any sector, prevention certainly is better than cure.
In order to gain a holistic overview of the network, technology managers need to design the infrastructure from the bottom up, starting with the physical layer, comprising devices and other hardware, and working up to the application layer. This multi-layered approach to security gives IT managers more visibility into the network so that they can see what data is coming into and leaving the network and can implement controls as required. For example, sensitive patient information can be encrypted as it traverses the network between devices, while less sensitive information, such as that collected by fitness devices, can be subject to less stringent protection measures.
Education of staff members is also critical. They need to be able to identify hacks such as spear phishing and ransomware attempts so that they know not to click on malicious links and to alert the IT department to such attempts. There also needs to be a general increase in awareness within the healthcare sector of the various methods used by cybercriminals to gain access to medical data. In many cases, medical institutions do not even know that they’ve been infiltrated purely because they don’t know the warning signs. They need to take a more proactive approach to network security and understand how to prevent certain attacks.
Security should not be reactive and should not be done just because organisations want to comply with legislation such as the Protection of Personal Information (POPI) Act. But unfortunately, this is the case in the healthcare industry and it’s the reason why they are always one step behind the attackers. Rather, security should be about prevention and the desire to ensure the integrity of sensitive information.
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.
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:
- 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.
- 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.
- 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.
- 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.
- 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.
