9 Main Security Challenges for the Future of the Internet Of Things (IoT)

Internet of Things (IoT) is one of the hottest technologies in the era of digital transformation, connecting everything to the Internet. It is the core technology behind smart homes, self-driving cars, smart utility meters, and smart cities. But there are nine main security challenges for the future of the internet of things (IoT).

The number of IoT devices is rapidly increasing over the last few years. According to an analyst firm Gartner, there will be more than 26 billion connected devices around the world by 2020, up from just 6 billion in 2016.

While IoT devices bring effective communication between devices, automate things, save time and cost and have numerous benefits, there is one thing still concerning the users—iot security. There have been specific incidents which have made the IoT devices challenging to trust.

Several smart TVs and cash machines have been hacked, which is negatively impacting the trust of not only consumers but also enterprises. Having said that, let’s have a deep dive into the most critical security challenges for the future of the Internet of Things (IoT).

1. Outdated hardware and software.

Since the IoT devices are being used increasingly, the manufacturers of these devices are focusing on building new ones and not paying enough attention to security.


A majority of these devices don’t get enough updates, whereas some of them never get a single one. What this means is that these products are secure at the time of purchase but becomes vulnerable to attacks when the hackers find some bugs or security issues.


When these issues are not fixed by releasing regular updates for hardware and software, the devices remain vulnerable to attacks. For every little thing connected to the Internet, the regular updates are a must-have. Not having updates can lead to data breach of not only customers but also of the companies that manufacture them.

2. Use of weak and default credentials.

Many IoT companies are selling devices and providing consumers default credentials with them — like an admin username. Hackers need just the username and password to attack the device. When they know the username, they carry out brute-force attacks to infect the devices.


The Mirai botnet attack is an example that was carried out because the devices were using default credentials. Consumers should be changing the default credentials as soon as they get the device, but most of the manufacturers don’t say anything in the instruction guides about making that change. Not making an update in the instruction guides leaves all of the devices open to attack.

3. Malware and ransomware.

The rapid rise in the development of IoT products will make cyberattack permutations unpredictable. Cybercriminals have become advanced today — and they lock out the consumers from using their own device.

For example, an IoT-enabled camera that captures confidential information from home or the work office — and the system is hacked. The attackers will encrypt the webcam system and not allow consumers to access any information. Since the system contains personal data, they can ask consumers to pay a hefty amount to recover their data. When this occurs, it’s called ransomware.

4. Predicting and preventing attacks.

Cybercriminals are proactively finding out new techniques for security threats. In such a scenario, there is a need for not only finding the vulnerabilities and fixing them as they occur but also learning to predict and prevent new
