Joining the dots

Whoever is responsible for the network, they will have to ensure that each and every IoT device – be it a smart meter, connected vehicle, security camera, etc. – can connect to the network when, where and how often users expect it to.

Whoever is responsible for the network, they will have to ensure that each and every IoT device – be it a smart meter, connected vehicle, security camera, etc. – can connect to the network when, where and how often users expect it to.

With billions of devices expected to populate the Internet of Things, RAHIEL NASIR wonders who is responsible for making sure they are connected, managed and delivering the data the end user needs.

You have probably heard all the headline-grabbing forecasts of the billions of devices that will be connected in the Internet of Things, and the trillions of dollars that the global market is expected to bring in for vendors, suppliers, network operators, etc.

And you’ll probably also be aware of the wide range of applications enabled by the IoT, from utility companies deploying smart meters and snacks firms monitoring their nationwide vending machines, to train operators managing their rolling stock and healthcare services keeping a remote eye on their patients.

There is now much talk about SD-WAN, but does it really represent the future of enterprise networking as some industry experts are suggesting? RAHIEL NASIR finds out.

The software defined wide area network has emerged as one of the “hottest” topics in the WAN industry, according to analysts at International Data Corporation (IDC). They believe the technology will play a key role in network evolution as organisations try to cope with the accelerating requirements resulting from digital transformation.

In a report published in June, IDC says the SD-WAN market represents a high growth opportunity for the many startups, established vendors and service providers that are now “jumping on the bandwagon”. It forecasts revenues for such firms to grow at an average rate of 92 per cent per year to reach $2.1bn (around £1.6bn) across the EMEA region by 2021.

In the face of rising and seemingly advanced cyber attacks, how can you keep your precious data safe? RAHIEL NASIR finds out how to put the hackers on the back foot.

On Friday 12 May 2017, a massive ransomware attack started to hit hundreds of organisations around the world.

At the time of writing this article just days later, the infosec community was still sifting through the evidence following the onslaught, and it was still not known whether the Wannacry virus (also known as WCryWanaCryptorWannaCrypt or Wana Decryptor) was state-sponsored, orchestrated by a hacker group, or the work of a lone teenager sitting in a suburban bedroom somewhere. 

So should network and data security breaches now be accepted as an everyday part of digital life where enterprises can do little to protect themselves?
