Security Challenges behind Internet of Things

Blog Post created by Marcus Jensen on Oct 13, 2015

Internet of things (IoT) is a network of physical objects and entities ranging from smart phones and washing machines to smart energy grids and embedded sensor systems. Everything with an off and on switch to the internet and the ability to transfer data automatically over the network is part of this cyber space.

By the 2020, it is estimated that some 26 billion devices worldwide will be connected to the internet. This is just one of the figures indicating the strong impact IoT has on how we live and the way we work. With such state of internet affairs, a solid infrastructure and security issues become the prime concern.


A vast virtual realm

With endless opportunities it offers, IoT also faces many companies with many cyber threats they don’t know how to deal with. The shortcomings are obvious, and they threat to make the development of IoT sluggish at best. Many businessmen strive to find not only an online tool solution that is tailored to their specific needs, but also one that doesn’t put them in deep water.

This lively cyber environment allows myriad of people to transfer data without any human interaction, or even the need to turn on the computer. Shared hosting environment of a virtual private server (VPS), for example, provides many benefits and boost the business productivity. But how is it possible to safeguard this complex realm of connected devices and networks?

Privacy is the big issue at a time when online file sharing is effortless. There are reports on police security systems, car washes and smart homes being hacked. Big corporations are throwing money at cyber security like there’s no tomorrow and companies like Kaspersky are sounding alarm bells. But, are these threats a bit overblown? They might be, but that doesn’t mean we shouldn’t take them seriously.

Internet of insecure things


The problem isn’t just in all those insecure devices, but the infrastructure behind it all as well. For example, VPS hosting is flourishing as many people find it difficult and costly to set up and manage their own server. All you need to do is to rent your virtual real estate and upload your files to it. But, that’s when the problems start, and VPS hosting around the world is going through some challenging times.

Thus, it’s best to segment the devices that are part of the IoT into separate networks, and restrict the access. The traffic should be than monitored 24/7 to find suspicious entries. Today we can find numerous VPS hosting services that mimic dedicated servers, but include only a portion of the server, not the whole of it. Hence, this is a convenient solution for those with lower traffic on websites and is way better security-wise.


This security-focused approach often means limiting the amount of data that is gathered and shared via IoT devices. Furthermore, whenever asked to provide a password, you make sure it is a strong one. Also, don’t forget to change default passwords on smart devices, otherwise you are connecting to the server with an insecure gadget.

Keep in mind that, however, that this is only the first line of defense, often insufficient to protect our data. Hence, some robust security measures such as data encryption are advisable. There is no silver bullet for those threats, though, and they are constantly evolving. A pro-active security is a priority when it comes to platforms like VPS, and that’s why it’s also important to update software on regular bases and patch it whenever possible.


Let there be interconnectedness


In the future, everything that can be connected to the internet will be connected to it. The immense ocean of interconnected people and devices is full of deadly thunderstorms and fierce winds. The moment they sense vulnerability, hackers and other digital pirates are attacking without mercy. Sophisticated and advanced security measures are called for, but the cyber attacks are always finding the Achilles’ heel. We probably won’t end in a dystopian future some Hollywood movies depict, but we won’t be taking a walk in the digital park either.
