5 ways to keep IoT safe

Published

As more devices connect to the Internet, so too does the chance of each of them being compromised. ERNST WITTMANN, Regional Manager for Southern Africa at Alcatel, gives some tips on how to protect these devices and ultimately yourselves.

The Internet of Things (IoT) is rapidly taking off as people and businesses connect everything from their cars, to their home automation systems, and to the Internet. These devices are starting to change how we live and work – allowing us to track our heart rates and calories with a fitness tracker, monitor and improve our driving habits via a vehicle telematics device, and so much more.

Yet connecting a device to the Internet exposes it to a range of information security threats. We have already seen hackers create botnets using connected fridges, webcams, smart DVRs and other IoT devices  and launch distributed denial-of-service (DDoS) attacks. And as we store more personal data – for example, health or payment information – on IoT devices, the risks of data theft and loss will multiply.

As we use the IoT for convenience, we must not treat privacy and security as an afterthought. The IoT devices could be the most vulnerable point in your home or office network. Here are five simple ways recommended by Alcatel, to improve the security of your information as you start to introduce more and more connected devices into your home or small business.

Don’t connect a device to the Internet unless there is a clear benefit for doing so

The most secure device is one that isn’t connected to the Internet in the first place. Ask yourself whether there’s really any benefit to connecting your fridge or your baby monitor to the Internet before you do it. And when you’re not using a device, consider disconnecting it from your network.

Create a separate guest network for IoT devices

Many Wi-Fi routers will allow you to set up multiple networks so that you can, for example, allow guests in your home or customers at your office to browse the Internet. Consider connecting your IoT devices to a separate Wi-Fi network to the one you use for your personal PC and mobile devices. This means that if someone gains access to the IoT device they won’t be able to use it to get to your other devices and information.

Use strong passwords for each device

You do use strong passwords to secure your PC and the many online services and applications you use, don’t you? Apply the same principle to any IoT devices you connect to the Internet. In addition to picking a strong password, it’s wise to pick different passwords for each device and different ones to the ones you use for email, online banking, social media and so on.

A hacker who gets a password and login name for one of your IoT devices will probably try it on other online services and devices. Using different details for each service and device means a hacker won’t have a skeleton key for all of your accounts and devices if he or she manages to break into your smoke detector or your media streaming device.

Bonus tip: Remember to change the password and login name for your router and all other devices when you first connect it to the Internet. Many people leave the default password and login in place – something like ‘admin’ – and make life easy for the criminals.

Stay updated with the latest firmware

When makers of IoT devices identify security vulnerabilities in their devices, they will usually release software updates to fix them. Installing the latest security patches for your devices’ firmware will help you reduce the chances of a successful attack. Check for updates every three months or so, or configure your devices to automatically download the latest patches.

Protect your smartphone, tablet and PC

It goes without saying that you should take all sensible steps to secure your PCs, tablets and smartphones since these are the devices you’ll usually use to log in to your router and your IoT gadgets. This includes ensuring you have up-to-date antimalware software, using strong passwords and so on.

You’ll often access your IoT devices, mobile banking, and many other services from a mobile app, so take good care of your smartphone. Secure access to the device behind a PIN or password when the screen is locked and set your phone up so you can remotely track its location and wipe your data if it gets lost or stolen.

Earth 2050: memory chips for kids, telepathy for adults

An astonishing set of predictions for the next 30 years includes a major challenge to the privacy of our thoughts.

Published

on

By 2050, most kids may be fitted with the latest memory boosting implants, and adults will have replaced mobile devices with direct connectivity through brain implants, powered by thought.

These are some of the more dramatic forecasts in Earth 2050, an award-winning, interactive multimedia project that accumulates predictions about social and technological developments for the upcoming 30 years. The aim is to identify global challenges for humanity and possible ways of solving these challenges. The website was launched in 2017 to mark Kaspersky Lab’s 20th birthday. It comprises a rich variety of predictions and future scenarios, covering a wide range of topics.

Recently a number of new contributions have been added to the site. Among them Lord Martin Rees, the UK’s Astronomer Royal, Professor at Cambridge University and former President of the Royal Society; investor and entrepreneur Steven Hoffman, Peter Tatchell, human rights campaigner, along withDmitry Galov, security researcher and Alexey Malanov, malware analyst at Kaspersky Lab.

The new visions for 2050 consider, among other things:

  • The replacement of mobile devices with direct connectivity through brain implants, powered by thought – able to upload skills and knowledge in return – and the impact of this on individual consciousness and privacy of thought.
  • The ability to transform all life at the genetic level through gene editing.
  • The potential impact of mistakes made by advanced machine-learning systems/AI.
  • The demise of current political systems and the rise of ‘citizen governments’, where ordinary people are co-opted to approve legislation.
  • The end of the techno-industrial age as the world runs out of fossil fuels, leading to economic and environmental devastation.
  • The end of industrial-scale meat production, as most people become vegan and meat is cultured from biopsies taken from living, outdoor reared livestock.

The hypothetical prediction for 2050 from Dmitry Galov, security researcher at Kaspersky Lab is as follows: “By 2050, our knowledge of how the brain works, and our ability to enhance or repair it is so advanced that being able to remember everything and learn new things at an outrageous speed has become commonplace. Most kids are fitted with the latest memory boosting implants to support their learning and this makes education easier than it has ever been. 

“Brain damage as a result of head injury is easily repaired; memory loss is no longer a medical condition, and people suffering from mental illnesses, such as depression, are quickly cured.  The technologies that underpin this have existed in some form since the late 2010s. Memory implants are in fact a natural progression from the connected deep brain stimulation implants of 2018.

“But every technology has another side – a dark side. In 2050, the medical, social and economic impact of memory boosting implants are significant, but they are also vulnerable to exploitation and cyber-abuse. New threats that have appeared in the last decade include the mass manipulation of groups through implanted or erased memories of political events or conflicts, and even the creation of ‘human botnets’. 

“These botnets connect people’s brains into a network of agents controlled and operated by cybercriminals, without the knowledge of the victims themselves.  Repurposed cyberthreats from previous decades are targeting the memories of world leaders for cyber-espionage, as well as those of celebrities, ordinary people and businesses with the aim of memory theft, deletion of or ‘locking’ of memories (for example, in return for a ransom).  

“This landscape is only possible because, in the late 2010s when the technologies began to evolve, the potential future security vulnerabilities were not considered a priority, and the various players: healthcare, security, policy makers and more, didn’t come together to understand and address future risks.”

How load-shedding is killing our cellphone signals

Published

on

Extensive load-shedding, combined with the theft of cell tower backup batteries and copper wire, is placing a massive strain on mobile network providers.

MTN says the majority of MTN’S sites have been equipped with battery backup systems to ensure there is enough power on site to run the system for several hours when local power goes out and the mains go down. 

“With power outages on the rise, these back-up systems become imperative to keeping South Africa connected and MTN has invested heavily in generators and backup batteries to maintain communication for customers, despite the lack of electrical power,” the operator said in a statement today.

However, according to Jacqui O’Sullivan, Executive: Corporate Affairs, at MTN SA, “The high frequency of the cycles of load shedding have meant batteries were unable to fully recharge. They generally have a capacity of six to 12 hours, depending on the site category, and require 12 to 18 hours to recharge.”

An additional challenge is that criminals and criminal syndicates are placing networks across the country at risk. Batteries, which can cost R28 000 per battery and upwards, are sought after on black markets – especially in neighbouring countries. 

“Although MTN has improved security and is making strides in limiting instances of theft and vandalism with the assistance of the police, the increase in power outages has made this issue even more pressing,” says O’Sullivan.

Ernest Paul, General Manager: Network Operations at SA’s leading network provider MTN, says the brazen theft of batteries is an industry-wide problem and will require a broader initiative driven by communities, the private sector, police and prosecutors to bring it to a halt.

“Apart from the cost of replacing the stolen batteries and upgrading the broken infrastructure, communities suffer as the network degrades without the back-up power. This is due to the fact that any coverage gaps need to be filled. The situation is even more dire with the rolling power cuts expected due to Eskom load shedding.”

Loss of services and network quality can range from a 2-5km radius to 15km on some sites and affect 5,000 to 20,000 people. On hub sites, network coverage to entire suburbs and regions can be lost.
