How to stay one step ahead of cyber threats

Published

on

Just under half of the companies surveyed in South Africa and the Middle East said they detected 50 or more threats in the last year. BRENDAN MCARAVEY, Country Manager, Citrix South Africa provides some tips on how to keep up with the cybercrime world.

In the recent PricewaterhouseCoopers’ Global State of Information Security Survey 2016, 41.44% of companies in South Africa and the Middle East reported that they had detected 50 or more cybersecurity incidents in the past 12 months. This was in comparison to the global total of 31.59%. A further 17.47% of South African and Middle Eastern companies had identified between 10 and 49 threats in the same time period.

These statistics are indicative of a constantly evolving beast – today’s information security landscape. As attack vectors continue to grow, assaults become more frequent and attackers become even more sophisticated. The need to continually adapt to an increasingly hostile environment has resulted in a significant change from the familiar security measures that kept us “comfortable” a mere five years ago. Although these measures are still valid, the reality is that they are nowhere near sufficient to combat the dangers of today’s increasingly complex threats.

Here are seven recommendations to help you keep up with the rapid pace of change in cybersecurity:

1.       Say goodbye to generic “best practices” security

Compliance is not a security programme – it’s a starting point. Any organisation that is still just ticking the boxes on their audit report is getting breached. Have this conversation in the boardroom and use it to drive the culture towards security that is specifically tailored to the business.

2.       Patching is a daily event

Flaws in applications, services such as DNS and foundational software, including OpenSSL, mean that, unlike a few years ago, we can’t wait a month or more for patches.  Ensure your organisation can respond with instant remediation across workstations, mobile, servers and clouds. Manage at the application level to respond without having to push new desktop images.

3.       Security just got personal

Targeted attacks go after specific individuals with personalised messages and payloads from an apparently trusted source. It’s getting more and more difficult – even for security professionals – to differentiate the malignant from the benign. And the highly rare APT ups the ante when the attacker has found a truly valuable target. More education is necessary, but can only go so far. Hardening must reduce the default attack surface as much as possible, and containment strategies further sandbox attacks.

4.       Breaches are to be expected

Formerly denied and only discussed in secret, breaches are now a reporting requirement for many organisations. A prescribed approach to incident management includes both technical and reputational responses. Containing breaches and their impact has been a deciding use case for app virtualisation across governments, healthcare and financial services. Virtualising all browser-based access is a leading practice for containing attacks against one of the most popular entry points for organisational breach.

5.       End-to-end strong encryption is mandatory

Encryption is no longer just for networks and hard drives. Encryption must protect sensitive data within and between applications, from desktops to mobile. Criminals have also recognised the value of encryption, with ransomware leveraging encryption as a weapon. And, as the painful death of SSL has shown, outdated encryption can be as bad as no encryption at all. Ensure that you control encryption for endpoints through app and desktop virtualisation, on mobile devices with enterprise mobility management, and for cloud and web apps with an application delivery controller with embedded web app firewall.

6.       Security begins with access 

A deep knowledge of situational context is necessary to control identity, authentication, authorisation and access control. Focus on the 5Ws of Access for employees and non-employees – who needs access, what are they accessing and when, where do they need access from, and why do they require access. Use virtualisation to provide fine-grained access control for privileged users and to ensure that there is no direct access to sensitive data.

7.       IT has competition

End users think they can do computing better themselves. And in some ways, they can. But not security. Ensure that Shadow IT, unsanctioned BYO and the use of consumer-grade apps, clouds and services for sensitive data are replaced with IT-controlled and sanctioned offerings. Simplify things for users by enabling single sign on, improving their access and automating a superior experience across devices.

This is by no means a prescriptive list. Information security teams should remain on guard at all times and aim to stay one step ahead of those who will take advantage of any negligence or ignorance. Nobody can afford to stand still. Attack vectors and exploitation methods will increase alarmingly, as more devices, people and locations become connected. And, as IoT becomes more of a reality, the need for sophisticated cybersecurity will increase exponentially. It’s time to keep watch, with both eyes open.

Samsung in lock-step with its rivals?

Tonight Samsung will kick off the next round in the smartphone wars with the S10 range, writes ARTHUR GOLDSTUCK.

Published

on

When Samsung unveils the new S10 smartphone at an event in San Francisco today, it will mark the beginning of the 2019 round of World War S. That stands for smartphone wars, although Samsung would like it to be all about the S.

Ever since the launch of the Samsung Galaxy S4 in 2013, Samsung has held both technology and thought leadership in the handset world. Back then, Apple’s iPhone 5 was the last device from the American manufacturer that could lay claim to being the best smartphone in the world. With the 2013 launch of the iPhone 5s, Apple entered an era of incremental improvement, playing catch-up, and succumbing to market trends driven by its competitors.

Six years later, Samsung is fighting off the same threat. Its Chinese rival, Huawei, suddenly wrested away leadership in the past year, with the P20 Pro and Mate 20 Pro regarded as at last equal to the Samsung Galaxy S9 Plus and Galaxy Note 9 – if not superior. Certainly, from a cost perspective, Huawei took the lead with its more competitive prices, and therefore more value for money.

Huawei also succeeded where Apple failed: introducing more economical versions of its flagship phones. The iPhone 5c, SE and XR have all been disappointments in the sales department, mainly because the price difference was not massive enough to attract lower-income users. In contrast, the Lite editions of the Huawei P9, P10 and P20 have been huge successes, especially in South Africa.

Today, for the first time in half a decade, Samsung goes into battle on a field laid out by its competitors. It is expected to launch the Galaxy S10 Plus, S10 and S10 e, with the latter being the Samsung answer to the strategy of the iPhone XR and Huawei P20 Lite.

Does this mean Samsung is now in lock-step with its rivals, focused on matching their strategies rather than running ahead of them?

It may seem that way, but Samsung has a few tricks up its electronic sleeve. For example, it is possible it will use the S10 launch to announce its coming range of foldable phones, expected to be called the Galaxy X, Galaxy F, Galaxy Fold or Galaxy Flex. It previewed the technology at a developer conference in San Francisco last November, and this will be the ideal moment to reclaim technology leadership by going into production with foldables – even if the S10 range itself does not shoot out the lights.

However, the S10 handsets will look very different to their predecessors. First, before switching on the phone, they will be notable by the introduction of what is being called the punch-hole display, which breaks away from the current trend of having a notch at the top of the phone to house front-facing cameras and speakers. Instead, the punch-hole is a single round cut-out that will contain the front camera. It is the key element of Samsung’s “Infinity O” display – the O represents the punchhole – which will be the first truly edge-to-edge display, on the sides and top.

The S10 range will use the new Samsung user interface, One UI, also unveiled at the developer conference. It replaces the previous “skin”, unimaginatively called the Samsung Experience, to introduce a strong new interface brand.

One UI went live on the Note 8 last month, giving us a foretaste, and giving Samsung a chance to iron out the bugs in the field. It is a less cluttered interface, addressing one of the biggest complaints about most manufacturer skins. Only Nokia and Google Pixel handsets offer pure Android in the local market, but One UI is Samsung’s best compromise yet.

It introduces a new interaction area, in the bottom half, reachable with the thumb, with a viewing area at the top, allowing the user to work one-handed on the bottom area while still having apps or related content visible above. One UI also improves gesture navigation – the phone picks up hand movements without being touched – and notification management.

The S10 range will be the first phones to feature the latest Qualcomm Snapdragon 855 chip, at least for the South African and American markets. That makes it 5G compatible, for when this next generation of mobile broadband becomes available in these markets.

They will also be the first phones to feature Wi-Fi 6, the next generation of the Wi-Fi mobile wireless standard. It will perform better in congested areas, and data transfer will be up to 40% faster than the previous generation.

The phones will be the first to use ultrasound for fingerprint detection. If Samsung gets it right, this will make it the fastest in-screen fingerprint sensor on the market, and allows for a little leeway if one pushes the finger down slightly outside the fingerprint reader surface. It does mean, however, that screen protectors will have to be redesigned to avoid blocking the detection.

Not enough firsts? There are a few more.

Most notably, it will be the first phone range to feature 1 Terabyte (TB) storage – that’s a thousand Gigabytes (GB) – at least for the top-of-the-range devices. Samsung last month announced that it would be the first manufacturer to make 1TB built-in onboard flash storage. Today, it will deploy this massive advantage as it once again weaponises its technology in the fight for smartphone domination.

IoT set to improve authentication

Published

on

By Sherry Zameer, Senior Vice President, Internet of Things Solutions for CISMEA region at Gemalto

As it rapidly approaches maturity, the Internet of Things (IoT) is set to continue a transformational trajectory, introducing new efficiencies in multiple fields by allowing measurement and analysis on a scale that has never been possible before. From agriculture to logistics, from retail to hospitality, from traffic to health, from the home to the office, the applications for monitoring ”things” are limited only by the imagination.

And South African (and African) businesses are showing abundant imagination in their practical deployments of IoT solutions in multiple settings, creating a better tomorrow through almost universal measurement and the introduction of new levels of convenience – including how to access locations, devices and services securely.

Any company, whether South African or international, should bear in mind that understanding consumer expectations can be the key to unlocking the full potential of IoT devices and related smart services.

According to Gemalto’s latest Connected Living study, improving the way consumers authenticate themselves to services is one of the most anticipated benefits of IoT, highlighting a desire for a more seamless and secure IoT experience.

Consumers are interested in advanced ways of authenticating themselves through automatic (based on behavioral patterns) or biometric techniques, lessening the need to have to intervene manually, all in the name of a much more streamlined authentication process. Smartphone manufacturers like Apple and Samsung have already placed fingerprint and facial recognition high on the agenda. There is also a widespread positive sentiment towards IoT’s potential for improving the quality of home life through connected, smart appliances.

Personalised services is something else that wins consumers over. In fact, a fluid, personalised and unified experience with continuity of services, together with security and privacy, is critical for the successful implementation of any technology.

And those types of services are today quite possible. With everything being connected – from small gadgets to digital solutions for large enterprises – IoT is no longer just a buzzword. That much is clear in a piece from Vodacom IoT managing executive Deon Liebenberg. Writing for IOL Online, Liebenberg provides insight into the sheer range of applications for IoT: the 20 use cases he cites range from the obvious, like transport and logistics, to the connected home and wearables; he even suggests tagging pets with IoT transmitters, for those who always need to know the whereabouts of the family cat.

Low-cost tags fitted to cats, dogs, lamp posts, shipping containers or other items are just one part of the puzzle, however. There are other two pieces; arguably the most complex part is the availability of communication networks in areas where there aren’t any WiFi networks, or indeed, anything else.

And that’s where the bigger takeaway from Liebenberg’s piece and other IoT trends articles becomes apparent. The communication networks are there, as are those tags: dedicated IoT networks (like LoraWAN, SigFox and narrowband IoT) are all available in South Africa.

So, too, is the third and final essential component. Software which is able to process the data generated by the tag and transmitted over the IoT network and into the internet. In this regard, there’s no shortage of solutions available from cloud providers like AWS and Azure; electronics giant Siemens, too, is in on the action, having recently launched a new cloud-based IoT operating system to develop applications and services for process industries, including oil and gas and water management.

This combination means it is quite possible right now to enable just about any use case. Business owners, who will know best how IoT can add value in their organisation, can now see their ideas becoming reality. Most crucial of all, IoT solutions delivering new levels of efficiency and convenience are not only possible, they are able to be offered with the simple and effective security that will drive consumer acceptance.
