Digital divide not bridged by broadband alone

Published

on

Although broadband can contribute to solving certain problems within developing markets, as an enabler of innovative new technologies, it is only a small component of the solution, writes ECKART ZOLLNER, Head of Business Development, The Jasco Group.

It is evident that telecommunications and connectivity within developed countries is continually gaining impetus, becoming more advanced and utilised.  On the other side of the spectrum, developing countries naturally lag behind, however, we are seeing the digital divide shrinking in some areas. The reality is that the rate of change within the developed world is beginning to reach a plateau while the developing world is catching up on technology. This is not to say that all of the challenges within the developing world have been addressed, and many of these issues remain. However, while broadband connectivity can contribute to solving certain problems within the developing market, as it is an enabler of innovative new technologies, it is only one small component of the solution.

In Africa, including countries such as South Africa, Kenya and Nigeria, there has been a significant amount of investment into developing and rolling out broadband infrastructure. From the initial connection of undersea cables to the continent by international players to the metro rings aimed at connecting cities, the market has now moved on to the last mile. The race is on to connect lucrative customers, and many providers are focusing on connecting entire suburbs as well as business, private homes, estates, retail centres and more. Driving the accelerated pace in the rollout of fibre and broadband connectivity is a growing adoption and acceptance of cloud-based solutions, as enterprises strive to reduce IT spend while still maintaining access to leading-edge technology. This increased demand from big business in turn helps to broaden customer reach of fibre technology and reduce the price, making it a more affordable solution for a wider proportion of the market.

In South Africa in particular, this process is assisted by a fairly open and deregulated market, which enables healthy competition to develop from numerous service providers. However, while access to broadband connectivity in terms of the infrastructure is becoming less of a challenge, the African market still faces a number of other challenges. By its very definition, the developing world often faces wider issues, including political instability, poverty, poor healthcare and education services for the majority of citizens, and a lack of economic activity, all of which need to be addressed. While broadband can assist in contributing to the solution in a number of these areas, it is only a small part of the solution.

Broadband can assist in the acceleration of economic activity, but this requires effective political governance, free and open market policies, effective regulation and a good understanding of best practices. The old model of state owned monopolies that still exists in many developing nations is not conducive to rapid broadband development, which may be hindering developing nations’ ability to take advantage of next-generation technology. In addition, broadband development requires significant investment, which many economies cannot undertake by themselves. It is therefore essential for developing nations to foster a climate that attracts foreign investment, in order to enable the development of the infrastructure that is needed to fully bridge the digital divide.

While the digital divide may not be getting deeper, it still exists, particularly within the geographic imbalance of broadband distribution in the majority of African countries. More speed is not necessarily the answer, but more pervasive access is certainly a step in the right direction. However, it is also important to bear in mind that technical literacy and skills development are essential components of addressing this challenge as well. Broadband, like any other technology, is not a magic wand, simply an enabler and a necessary platform. Opportunities still need to be developed, which requires support from government for innovation and entrepreneurship. While broadband can help to connect providers of services with a far larger market, and connect suppliers, markets and information crucial for success, it is by no means a silver bullet. Technology is a supporting tool, but ultimately people lie at the heart of innovation and support and leadership is needed to drive this.

Whilst Broadband can become the bright light to accelerate change and economic progress, it is the political and regulatory fundamentals that need to follow global best practices to allow broadband deployment to flourish. Countries that have committed to the correct governance models with effective law making and regulation are already starting to show leadership in the adoption and deployment of broadband and subsequent innovation.

Which IoT horse should you back?

The emerging IoT is evolving at a rapid pace with more companies entering the market. The development of new product and communication systems is likely to continue to grow over the next few years, after which we could begin to see a few dominant players emerge, says DARREN OXLEE, CTOf of Utility Systems.

But in the interim, many companies face a dilemma because, in such a new industry, there are so many unknowns about its trajectory. With the variety of options available (particularly regarding the medium of communication), there’s the a question of which horse to back.

Many players also haven’t fully come to grips with the commercial models in IoT (specifically, how much it costs to run these systems).

Which communication protocol should you consider for your IoT application? Depends on what you’re looking for. Here’s a summary of the main low-power, wide area network (LPWAN) communications options that are currently available, along with their applicability:

SIGFOX 

SigFox has what is arguably the most traction in the LPWAN space, thanks to its successful marketing campaigns in Europe. It also has strong support from vendors including Texas Instruments, Silicon Labs, and Axom.

It’s a relatively simple technology, ultra-narrowband (100 Hz), and sends very small data (12 bytes) very slowly (300 bps). So it’s perfect for applications where systems need to send small, infrequent bursts of data. Its lack of downlink capabilities, however, could make it unsuitable for applications that require two-way communication.

LORA 

LoRaWAN is a standard governed by the LoRa Alliance. It’s not open because the underlying chipset is only available through Semtech – though this should change in future.

Its functionality is like SigFox: it’s primarily intended for uplink-only applications with multiple nodes, although downlink messages are possible. But unlike SigFox, LoRa uses multiple frequency channels and data rates with coded messages. These are less likely to interfere with one another, increasing the concentrator capacity.

RPMA 

Ingenu Technology Solutions has developed a proprietary technology called Random Phase Multiple Access (RPMA) in the 2.4 GHz band. Due to its architecture, it’s said to have a superior uplink and downlink capacity compared to other models.

It also claims to have better doppler, scheduling, and interference characteristics, as well as a better link budget of 177 dB compared to LoRa’s 157 dB and SigFox’s 149 dB. Plus, it operates in the 2.4 GHz spectrum, which is globally available for Wi-Fi and Bluetooth, so there are no regional architecture changes needed – unlike SigFox and LoRa.

LTE-M 

LTE-M (LTE Cat-M1) is a cellular technology that has gained traction in the United States and is specifically designed for IoT or machine‑to‑machine (M2M) communications.

It’s a low‑power wide‑area (LPWA) interface that connects IoT and M2M devices with medium data rate requirements (375 kb/s upload and download speeds in half duplex mode). It also enables longer battery lifecycles and greater in‑building range compared to standard cellular technologies like 2G, 3G, or LTE Cat 1.

Key features include:

·       Voice functionality via VoLTE

·       Full mobility and in‑vehicle hand‑over

·       Low power consumption

·       Extended in‑building range

NB-IOT 

Narrowband IoT (NB‑IoT or LTE Cat NB1) is part of the same 3GPP Release 13 standard3 that defined LTE Cat M1 – both are licensed as LPWAN technologies that work virtually anywhere. NB-IoT connects devices simply and efficiently on already established mobile networks and handles small amounts of infrequent two‑way data securely and reliably.

NB‑IoT is well suited for applications like gas and water meters through regular and small data transmissions, as network coverage is a key issue in smart metering rollouts. Meters also tend to be in difficult locations like cellars, deep underground, or in remote areas. NB‑IoT has excellent coverage and penetration to address this.

MY FORECAST

The LPWAN technology stack is fluid, so I foresee it evolving more over the coming years. During this time, I suspect that we’ll see:

1.     Different markets adopting different technologies based on factors like dominant technology players and local regulations

2.     The technologies diverging for a period and then converging with a few key players, which I think will be SigFox, LoRa, and the two LTE-based technologies

3.     A significant technological shift in 3-5 years, which will disrupt this space again

So, which horse should you back?

I don’t believe it’s prudent to pick a single technology now; lock-in could cause serious restrictions in the long-term. A modular, agile approach to implementing the correct communications mechanism for your requirements carries less risk.

The commercial model is also hugely important. The cellular and telecommunications companies will understandably want to maximise their returns and you’ll want to position yourself to share an equitable part of the revenue.

So: do your homework. And good luck!

Ms Office hack attacks up 4X

Published

on

Exploits, software that takes advantage of a bug or vulnerability, for Microsoft Office in-the-wild hit the list of cyber headaches in Q1 2018. Overall, the number of users attacked with malicious Office documents rose more than four times compared with Q1 2017. In just three months, its share of exploits used in attacks grew to almost 50% – this is double the average share of exploits for Microsoft Office across 2017. These are the main findings from Kaspersky Lab’s Q1 IT threat evolution report.

Attacks based on exploits are considered to be very powerful, as they do not require any additional interactions with the user and can deliver their dangerous code discreetly. They are therefore widely used; both by cybercriminals looking for profit and by more sophisticated nation-backed state actors for their malicious purposes.

The first quarter of 2018 experienced a massive inflow of these exploits, targeting popular Microsoft Office software. According to Kaspersky Lab experts, this is likely to be the peak of a longer trend, as at least ten in-the-wild exploits for Microsoft Office software were identified in 2017-2018 – compared to two zero-day exploits for Adobe Flash player used in-the-wild during the same time period.

The share of the latter in the distribution of exploits used in attacks is decreasing as expected (accounting for slightly less than 3% in the first quarter) – Adobe and Microsoft have put a lot of effort into making it difficult to exploit Flash Player.

After cybercriminals find out about a vulnerability, they prepare a ready-to-go exploit. They then frequently use spear-phishing as the infection vector, compromising users and companies through emails with malicious attachments. Worse still, such spear-phishing attack vectors are usually discreet and very actively used in sophisticated targeted attacks – there were many examples of this in the last six months alone.

For instance, in late 2017, Kaspersky Lab’s advanced exploit prevention systems identified a new Adobe Flash zero-day exploit used in-the-wild against our customers. The exploit was delivered through a Microsoft Office document and the final payload was the latest version of FinSpy malware. Analysis of the payload enabled researchers to confidently link this attack to a sophisticated actor known as ‘BlackOasis’. The same month, Kaspersky Lab’s experts published a detailed analysis of СVE-2017-11826, a critical zero-day vulnerability used to launch targeted attacks in all versions of Microsoft Office. The exploit for this vulnerability is an RTF document containing a DOCX document that exploits СVE-2017-11826 in the Office Open XML parser. Finally, just a couple of days ago, information on Internet Explorer zero day CVE-2018-8174 was published. This vulnerability was also used in targeted attacks.

“The threat landscape in the first quarter again shows us that a lack of attention to patch management is one of the most significant cyber-dangers. While vendors usually issue patches for the vulnerabilities, users often can’t update their products in time, which results in waves of discreet and highly effective attacks once the vulnerabilities have been exposed to the broad cybercriminal community,” notes Alexander Liskin, security expert at Kaspersky Lab.

Other online threat statistics from the Q1, 2018 report include:

  • Kaspersky Lab solutions detected and repelled 796,806,112 malicious attacks from online resources located in 194 countries around the world.
  • 282,807,433 unique URLs were recognised as malicious by web antivirus components.
  • Attempted infections by malware that aims to steal money via online access to bank accounts were registered on 204,448 user computers.
  • Kaspersky Lab’s file antivirus detected a total of 187,597,494 unique malicious and potentially unwanted objects.
  • Kaspersky Lab mobile security products also detected:
    • 1,322,578 malicious installation packages.
    • 18,912 mobile banking Trojans (installation packages).

To reduce the risk of infection, users are advised to:

  • Keep the software installed on your PC up to date, and enable the auto-update feature if it is available.
  • Wherever possible, choose a software vendor that demonstrates a responsible approach to a vulnerability problem. Check if the software vendor has its own bug bounty program.

·         Use robust security solutions , which have special features to protect against exploits, such as Automatic Exploit Prevention.

·         Regularly run a system scan to check for possible infections and make sure you keep all software up to date.

  • Businesses should use a security solution that provides vulnerability, patch management and exploit prevention components, such as Kaspersky Endpoint Security for Business. The patch management feature automatically eliminates vulnerabilities and proactively patches them. The exploit prevention component monitors suspicious actions of applications and blocks malicious files executions.
