IoT connects devices across the internet. As more and more devices and systems are embedded with network connectivity, the IoT network is keeping on growing. By expanding network connectivity to all corners of our life, we can save time and money and improve the efficiency of our lives.

A deeper analysis of the IoT network reveals various cyber threats that could be detrimental to the users and the devices. Expanded internet connectivity exposes various entry points to bad actors that can take advantage of the loopholes and perform malicious acts.

Cybersecurity Threats In The IoT System

It was in 2016 that the first wave of IoT cyber threats began when the Mirai Botnet compromised the security of many IoT devices, which include routers and IP cameras. The compromised security turned the devices into centrally controlled botnets that affected the internet connection of a million users worldwide.

Companies around the world are adopting various IoT solutions targeting better visibility and improved efficiency. Meanwhile, attackers are on the constant lookout for newer ways to gain unauthorized access to systems and data stores and compromise them. Starting from navigation systems in vehicles to IoT enabled medical devices, hackers can literally target anything.

Securing IoT Systems

Securing IoT systems is a challenging task for many reasons. Manufacturers and innovators are undergoing immense pressure to introduce newer devices that suffice the latest market needs. In the process, security is often given low priority. Moreover, many businesses are even unaware of the vulnerabilities in the IoT network because they give more attention to the convenience and cost-saving benefits of IoT.

Gartner predicts that over 25% of the enterprise attacks by 2020 will involve IoT systems. The risk is significantly high for Industrial IoT systems.

Securing the devices themselves is one way to approach the problem. For example, some equipment may not require constant monitoring during their operation but they still need to be secured. By applying tamper-proof precautions, these endpoints can be secured to prevent intruders from tapping into the devices and accessing critical data.

It isn’t just the IoT devices that should be secured. Organizations need to put in the effort to secure their IoT networks. By deploying strong user identification and access control mechanisms, it can be ensured that only authorized users are gaining access to the system.

It is not really possible to prevent the occurrence of IoT attacks altogether but organizations can still implement solutions that can effectively mitigate the cybersecurity threats.

Top Tips To Ensure IoT Device Security

Internet of things (IoT) devices are becoming more popular among users because they let people control devices remotely. For example, IoT enables control of lights, thermostats, digital locks, and home appliances, etc., from afar. This helps improve home security. Additionally, smart devices are also part of this ecosystem through which we control IoT devices mentioned previously. However, these devices are prone to security lapses which make them easy targets for cybercrimes. Shared below are tips to ensure IoT cybersecurity so that these devices do not get hacked easily.

Change The Default Setting Of The Router

The preliminary step when you begin using any router is to change the default name and set a new password. This makes it difficult for people to access the device and makes them less prone to hacking. When creating a password, make sure to use a combination of numbers, alphabets, and symbols that are not correlated. As a rule of thumb, the more uncommon the name the more difficult it will be to crack it.

Create Strong Passwords

Creating strong passwords for the router is the other important step to secure the IoT devices. This reduces the risk of being hacked. It is always recommended to create a strong, elaborate, and complex password to protect the IoT ecosystem. As stated earlier, use a combination of numbers, alphabets both upper and lower cases, and symbols to create a strong password. Ensure that the password is long enough, and avoid using any kind of personal information. One common mistake people often make is that they use the same passwords for multiple accounts, and this must be avoided.

Update IoT Devices

Updating device software is the key to IoT device security, and it ensures that there aren’t any security flaws. It applies to all the devices using a Wi-Fi network, including the antivirus and antimalware software of laptops or smartphones. If one of the IoT devices is compromised, it can compromise the whole ecosystem. Also, keep in mind that hackers or cybercriminals are always improving their game.

Two Factor Authentication

The two-factor authentication that we employ for emails or banking transactions can be used for IoT cybersecurity. The advantage of this method is that it enables you to be in control of who gets to access the IoT ecosystem. If anyone accesses the network, you will be notified immediately to grand further access.

We hope that the tips shared above will ensure IoT device securityand protect them from hacking.

Predictions for Iot Security Next Year

IoT Cybersecurity

One thing is certain in each December: experts of most industries make predictions on what is in store the year after. IoT experts too have come up with their own predictions. They say that it is a fascinating time ahead for cybersecurity. They did not hold back when making their predictions for 2020. Here is a rundown of some of their predictions when it comes to IoT device security.

  • Shorter validity times are likely for Transport Layer Security (TLS) certificates. So, companies will have to start adopting automation to facilitate certificate management.
  • Users will need to have more awareness about security because malicious actors exploit free DV (domain validated) certificates to display the padlock icon on their sites.
  • Hackers will keep finding vulnerabilities in devices because IoT cybersecurity is not the greatest priority when these are made. Some improvements have been seen, but the industry hopes for more.
  • The year 2019 saw the implementation of the California Consumer Privacy Act (CCPA) as well as the failed New York Privacy Act (NYPC). There is a drive for a nationwide privacy act, but in the Trump administration, that is less likely to happen. Even so, users are concerned about privacy violations. American states are implementing their own decrees to fill the holes, but this move is going to make compliance extremely tricky for organizations. This is because of the pieced together nature of implementation.
  • National Institute of Standards and Technology will standardize a quantum-proof algorithm by the period 2022 to 2024, starting a universal attempt to deploy the algorithm. Organizations that emphasize cryptographic agility and inventory cryptographic systems will have an easy time implementing it. However, other companies will not find as easy to do.
  • A quantum computation device is going to resolve an economically significant issue in 2020. This will start a new age of financial investment in speeding up quantum computing’s development, on the basis of the presentation of practical advantages. The implementation of quantum-proof cryptography will have to progress.
  • We are going to see more exploits on public IoT-enabled devices, which will make regulators strengthen their stance the on the internet of things security. More governments around the globe will bring in the internet of things security regulation.
  • Industries will unite in a bid to make standards for protecting IoT devices against threats they face.
