Internet of Things (IoT) is now not just a talking topic – it is now absolutely here with new connected devices arriving with their own security vulnerabilities – however, we are now starting to see the security for IoT advance.
The Internet of Things (IoT) has long been a game of rush-to-market, with production speed trumping security in the stampede, says ESET Southern Africa.
Securing millions of non-standard devices as disparate as home thermometers, smart TVs and cars is no trivial task. It is somewhat simpler if they have simple stripped down embedded processors, but often they contain full-fledged and powerful network-connected operating systems, with all the security problems those present.
In years past, it was non-obvious whether vendors were attempting to create security solutions without a corresponding real world threat. But as we see Android-related malware numbers steadily climb, it is no longer rare to spot scams or worse, on the platform. Additionally, as the importance and placement of IoT devices in more critical applications increases (think: “cars“), keeping rogue processes contained – regardless of their origin – seems wise.
One approach is to make each operating process mutually suspicious, containerize ed and separate from each other. But development is slower than just bolting on a standard OS like Android and shipping the product.
The good news is that Android security vendors here are implementing increasingly secure environments, but the rate of adoption is still far outpaced by the number of new devices hitting the market with unknown and unproven security chops.
Back to the mutually suspicious, or trusted computing platforms. While more difficult to develop against, they are typically far more resistant to attack. This has garnered the attention specifically of the automotive, government, and critical infrastructure market segments.
Luckily the companies like Lynx Software Technologies have been at it for some time now, and offer unique ways to approach the problem, with everything isolated – cores, memory, application, system and other resources – to form a very breach-resistant constellation of digital barriers that would curb the spread of nasty things. This sort of “paranoia” is most welcome in applications like avionics or medical devices, where no one wants to see “bad things” happen, and fundamentally, no-one wants. Prevention is better than detection.
Also, the network security folks have focused squarely on defending against rogue threats found on networks you might not think to look at, like CAN bus on automotive, or even ICS-related protocols like Modbus, which have been lightly defended (if at all) for decades.
As the importance and popularity of IoT continues to escalate and people place more valuable information thereupon, scammers and more hardened cybercriminals, will continue to look for new ways of attacking and compromising the swarm of devices which now surround us.
Legion gets a pro makeover
Lenovo’s latest Legion gaming laptop, the Y530, pulls out all the stops to deliver a sleek looking computer at a lower price point, writes BRYAN TURNER
Gaming laptops have become synonymous with thick bodies, loud fans, and rainbow lights. Lenovo’s latest gaming laptop is here to change that.
The unit we reviewed housed an Intel Core i7-8750H, with an Nvidia GeForce GTX 1060 GPU. It featured dual storage, one bay fitted with a Samsung 256GB NVMe SSD and the other with a 1TB HDD.
The latest addition to the Legion lineup has become far more professional-looking, compared to the previous generation Y520. This trend is becoming more prevalent in the gaming laptop market and appeals to those who want to use a single device for work and play. Instead of sporting flashy colours, Lenovo has opted for an all-black computer body and a monochromatic, white light scheme.
The laptop features an all-metal body with sharp edges and comes in at just under 24mm thick. Lenovo opted to make the Y530’s screen lid a little shorter than the bottom half of the laptop, which allowed for more goodies to be packed in the unit while still keeping it thin. The lid of the laptop features Legion branding that’s subtly engraved in the metal and aligned to the side. It also features a white light in the O of Legion that glows when the computer is in use.
The extra bit of the laptop body facilitates better cooling. Lenovo has upgraded its Legion fan system from the previous generation. For passive cooling, a type of cooling that relies on the body’s build instead of the fans, it handles regular office use without starting up the fans. A gaming laptop with good passive cooling is rare to find and Lenovo has shown that it can be achieved with a good build.
The internal fans start when gaming, as one would expect. They are about as loud as other gaming laptops, but this won’t be a problem for gamers who use headsets.

Serious about security? Time to talk ISO 20000
By EDWARD CARBUTT, executive director at Marval Africa
The looming Protection of Personal Information (PoPI) Act in South Africa and the introduction of the General Data Protection Regulation (GDPR) in the European Union (EU) have brought information security to the fore for many organisations. This in addition to the ISO 27001 standard that needs to be adhered to in order to assist the protection of information has caused organisations to scramble and ensure their information security measures are in line with regulatory requirements.
However, few businesses know or realise that if they are already ISO 20000 certified and follow Information Technology Infrastructure Library’s (ITIL) best practices they are effectively positioning themselves with other regulatory standards such as ISO 27001. In doing so, organisations are able to decrease the effort and time taken to adhere to the policies of this security standard.
ISO 20000, ITSM and ITIL – Where does ISO 27001 fit in?
ISO 20000 is the international standard for IT service management (ITSM) and reflects a business’s ability to adhere to best practice guidelines contained within the ITIL frameworks.
ISO 20000 is process-based, it tackles many of the same topics as ISO 27001, such as incident management, problem management, change control and risk management. It’s therefore clear that if security forms part of ITSM’s outcomes, it should already be taken care of… So, why aren’t more businesses looking towards ISO 20000 to assist them in becoming ISO 27001 compliant?
The link to information security compliance
Information security management is a process that runs across the ITIL service life cycle interacting with all other processes in the framework. It is one of the key aspects of the ‘warranty of the service’, managed within the Service Level Agreement (SLA). The focus is ensuring that the quality of services produces the desired business value.
So, how are these standards different?
Even though ISO 20000 and ISO 27001 have many similarities and elements in common, there are still many differences. Organisations should take cognisance that ISO 20000 considers risk as one of the building elements of ITSM, but the standard is still service-based. Conversely, ISO 27001 is completely risk management-based and has risk management at its foundation whereas ISO 20000 encompasses much more
Why ISO 20000?
Organisations should ask themselves how they will derive value from ISO 20000. In Short, the ISO 20000 certification gives ITIL ‘teeth’. ITIL is not prescriptive, it is difficult to maintain momentum without adequate governance controls, however – ISO 20000 is. ITIL does not insist on continual service improvement – ISO 20000 does. In addition, ITIL does not insist on evidence to prove quality and progress – ISO 20000 does. ITIL is not being demanded by business – governance controls, auditability & agility are. This certification verifies an organisation’s ability to deliver ITSM within ITIL standards.
Ensuring ISO 20000 compliance provides peace of mind and shortens the journey to achieving other certifications, such as ISO 27001 compliance.
