A Guide to IoT Security: Protecting Your Connected Devices from Hackers


The Internet of Things (IoT) continues to expand and become an increasingly integral part of our daily lives. These days, It’s more important than ever to ensure that we practice well-implemented IoT Security. Hackers constantly find new ways to infiltrate and exploit IoT devices, putting sensitive information and personal privacy at risk.

Hence, there is a need to protect internet-connected devices from cyber-attacks and unauthorized access by implementing IoT security. These devices, also known as IoT devices, include smart thermostats, security cameras, and smart appliances.

In this article, we will provide a comprehensive guide to IoT security, covering the most effective ways to protect your connected devices from possible threats. From understanding the common vulnerabilities of IoT devices to introducing strong passwords and transitioning to secure networks. We’ll cover key some IoT device security concepts and effective IoT security solutions.

What is IoT Security and What are The Threats It Protects Us from?

IoT security refers to the measures taken to protect internet-connected devices from cyber-attacks and unauthorized access. These include smart thermostats, security cameras, and smart appliances. These devices, which make up the Internet of Things (IoT), are susceptible to a large range of cyber threats such as malware attacks.

Many of these devices tend to cut corners to reduce costs, which leads to potential vulnerabilities. Naturally, this implies that the manufacturers of these devices have not taken enough steps to protect against IoT threats. As a result, these devices can be easily hack and used to gain access to networks and personal information.

In addition to traditional cyber threats, IoT devices also pose a physical security risk. Hackers can break into connected security cameras and use them to monitor unauthorized areas. Similarly, a smart lock could be hacked and used to gain unauthorized access to a building.

The risks of IoT security extend beyond individual devices and can also impact entire networks. For example, someone could intrude into a network of connected devices as a platform for a coordinated attack. This can cause widespread disruptions, outages, and serious damage to infrastructure.

What Are The 5 Ways To Protect Your Connected Devices From Hackers?

There are many different ways to add an extra layer of security against hackers for your IoT devices. Each way varies in effectiveness and cost. However, we have compiled the 5 that are most convenient to implement and boost your IoT security with actionable steps:

  1. Avoid weak passwords
  2. Make use of Two-Factor Authentication (2-FA)
  3. Ensure that you always have the latest software updates installed
  4. Avoid using unfamiliar networks
  5. Use firewalls and antivirus software

We will look at each of these IoT device security concepts and effective IoT security solutions in detail. See how IoT security can be implemented in your connected devices to protect yourself from any cyber-attacks.

1. Avoid weak passwords

To start, one of the most effective ways to start working towards a secure IoT ecosystem is to protect your connected devices from hackers. This can be through using strong, unique passwords for each of your accounts. As a general guide, these passwords should be at least 8 characters long and have a mix of special characters.

This goes without saying, but avoid using common words or phrases as your passwords. These include “password123” or “qwerty,” as these are obviously accessible to hackers and do not take long for them to decrypt. Instead, consider using a password manager as a means to upgrade your password security.

2. Make use of Two-Factor Authentication (2FA)

You can take actionable steps to protect your accounts by enabling Two-Factor Authentication (2FA) on all of your accounts. This buffers your IoT device security, by securing your devices across multiple platforms.

This increases your protection for your accounts against hackers, even if they are able to guess or steal your password. For example, let’s say that a hacker tries to log into your online banking account using your password. With 2FA enabled, the hacker would also need to have access to your phone or email in order to complete the login process.

In short, 2FA can provide an important layer of protection for your accounts. To enable 2FA, simply follow the instructions provided by your device or service, most of which are extremely user-friendly and easy to follow. Many popular websites and apps, such as Google, Facebook, and Twitter, offer 2FA as an option.

3. Ensure that you always have the latest software updates installed

One way to boost your IoT security is surprisingly simple and often overlooked. It’s essential to keep your connected devices up to date with the latest patches and updates. These updates usually include fixes for vulnerabilities and other security improvements, so installing them as soon as they are available is important.

For example, even in the home setting, let’s say that you own a smart thermostat that has a security vulnerability that allows hackers to gain access to your home network. If the manufacturer releases an update that fixes this vulnerability, it’s important to install the update as soon as possible to protect your device and your network.

To make this process easier, consider enabling automatic updates for your devices and software. This is a feature that is widely adopted by many products already. This way, you can be sure that your devices and software are always up-to-date and secure.

4. Avoid using unfamiliar networks

When using unfamiliar networks, such as public Wi-Fi hotspots, it’s important to be cautious and take steps to protect your data. Hackers can easily set up fake Wi-Fi hotspots that are designed to steal your personal information and login credentials. It is more common than you would think.

One way to safeguard your information while using public Wi-Fi is with a VPN, or Virtual Private Network. Essentially, a VPN encrypts your internet connection, making it more difficult for hackers to intercept your data. Additionally, it is best practice to refrain from accessing sensitive information or conducting financial transactions on public networks.

For example, it’s probably not a good idea to log into your online banking account or enter your credit card information while connected to a public Wi-Fi hotspot. Unless you really have to process sensitive information on a foreign network, consider using a personal hotspot or a secure, private network whenever possible.

5. Use firewalls and antivirus software

Firewalls and antivirus software are essential tools for protecting your devices and networks from cyber threats.

A firewall is a piece of software that you have most probably seen before on your devices. It is a system that regulates the flow of network traffic based on predefined security protocols. It can also assist in blocking unapproved access to your network and can be an effective way of preventing unauthorized individuals, such as hackers, from accessing your devices.

Antivirus software, on the other hand, is designed to detect and remove malware and other malicious software from your devices. As a widely used software, its popularity has dropped in recent times. However, this can help to safeguard your devices from attacks so it is still highly recommended to have one for your device ecosystem.

To ensure that your devices are protected, it’s important to install and enable both of these programs and keep them up to date. Many operating systems, such as Windows and macOS, include built-in firewalls and antivirus software. You may already have these tools installed on your devices. If not, there are many excellent third-party options available. Just be sure to do your research and choose a reputable program.
