Security Impact of IoT: Risks and Challenges

Security Impact of IoT: Risks and Challenges

To truly grasp the security impact of the Internet of Things (IoT), it’s crucial to understand what the IoT itself entails. In essence, the IoT connects physical objects, software, sensors, and various technologies, forming a sophisticated network that aids us in our daily lives For example, your refrigerator is connected to the internet, alerting your phone when you’re low on milk for dinner.

Security impact of IOT

This is just one example of the Internet of Things (IoT) in action, a technology rapidly gaining traction not just for consumers but also in sophisticated industrial tools used by businesses. The number of IoT devices is increasing every day, “the expected number of IoT devices all over the world will be 25 Billion by 2025” As says.

Yes! The internet devices which connected are a lot, even more than people themselves, As this part of technology grows rapidly, the security impact of IoT is growing too. Let’s discuss how these risks work, and how to mitigate them.

The above picture shows how many devices are connected to the internet in just Saudi Arabia and what the Shodan IoT search engine could archive only!

As IoT technology became an essential thing for enterprises, ethical considerations became a significant concern. Using IoT in your business is so advantageous, for example, you can use sensors and camera data to collect and analyze the actions and reactions of your customers in your store.

This kind of information will be a game-changer for businesses to enhance the service. The use of advanced IoT devices and data made it so easy for companies to monitor and predict user behavior side-by-side with efficient AI tools. After knowing the positive side of IoT technology, it’s time to expose the disadvantages. The top security impact of IoT is the violation of privacy which can affect the reputation of your enterprise.

You must follow regulations such as GDPR (if your business targets Europe countries) or the Kingdom of Saudi Arabia Personal Data Protection Law (if your business targets Saudi Arabian customers). From a cybersecurity perspective, It extends the attack surface, more IoT devices means more chances and possible vulnerabilities for malicious hackers. Usually, IoT comes with bad security countermeasures. In addition to that, IoT devices are connected directly to the local network which means the possibility to access other critical resources in the network. According to a Forbes report, cyberattacks surged by 300%, more than 2.9 billion events in 2019 alone.

Every new feature of technology is commonly exploited by hackers especially if it’s something that needs an internet connection such as IoT.

Passwords are the first-line defensive method against malicious hackers, but if your password is not very strong, it can be cracked. The weak design of the authentication is the main source of this issue.

for instance, IoT devices must force you to change the default credentials after first login, And They must have strict security policies the length of the password is only more than 8 + have both capital and small letters with at least one number. Most of the successful cyberattacks in IoT happened because of default passwords.

Imagine a smart light bulb or fitness tracker. Cool, right? Now imagine them struggling to update their defenses, like a knight in rusty armor. That’s the security impact of low processing power in many IoT devices.

They juggle limited data to save costs and battery, but this weakness comes at a price: vulnerability to hacking. Firewalls, virus scanners, encryption – these cybersecurity heroes need processing power, which our little gadget friends lack. So, the burden falls on the network they connect to. That’s why strong network security is crucial, acting as the iron shield for these tech underdogs. Remember, even the smallest devices deserve protection in our connected world.

Sharing your Wi-Fi with your smart toaster might seem convenient, but it’s like leaving your front door unlocked! Hackers can use a compromised IoT device as a stepping stone to access your entire network, stealing sensitive data or wreaking havoc. To avoid this messy finger-pointing between you and the manufacturer, give your smart gadgets their own secure network or firewall. Think of it like a security guard for your tech crew – keeping the bad guys out and the good guys (your data) safe!

Many lack “encryption,” meaning sensitive info like passwords or voice commands fly around unmasked. This makes them easy pickings for hackers lurking in the digital shadows, who can then use that info to wreak havoc on your network. Bottom line: encryption is crucial for securing our chatty IoT devices!

Forget to update your phone? Imagine forgetting to patch a vulnerability in your smart fridge! Many IoT devices cannot receive essential firmware updates, leaving them open to attacks like a castle with unguarded gates. These bugs, whether in the manufacturer’s code or from third parties, can create major security headaches. While remote updates are ideal, some devices might require a physical fix due to limited network capabilities. Don’t let outdated IoT gadgets become ticking time bombs – make sure updates are a possibility before bringing them into your connected world.

Do you remember the attack of 2016 of Mirai Botnet? when popular websites like Twitter (X) and Netflix went dark! That wasn’t imagination, but a chilling reminder of the security impact of IoT. The culprit? The Mirai botnet, an army of hacked internet-connected devices like cameras and routers, turned into a powerful weapon.

By exploiting weak passwords and security flaws, this “army of the dead” unleashed massive cyberattacks, crippling online services and highlighting the vulnerability of our increasingly connected world. It’s a stark reminder that securing our smart gadgets isn’t just about convenience, it’s about protecting ourselves in the digital age.

In 2017, Hackers potentially gained access to over 465,000 pacemakers, devices meant to regulate hearts and keep people alive. The consequences were unthinkable: hackers could tamper with vital settings, drain batteries, or even deliver painful shocks – turning a life-saving device into a deadly weapon.

Thankfully, no such attacks materialized, and St. Jude Medical swiftly secured the devices. However, the incident served as a stark reminder of the immense security risks in our growing world of connected devices, highlighting the crucial need for robust safeguards in even the most critical technologies. It’s a sobering story that demands vigilant attention to IoT security before a potential nightmare becomes a tragic reality.

In 2015, security researchers proved it by hacking a Jeep’s multimedia system, gaining access to crucial parts like the engine and brakes. This chilling feat exposed a major security gap in our increasingly connected vehicles, highlighting the very real dangers lurking in the “Internet of Things.” Keeping our cars safe demands robust digital defenses, because the last thing we want is a joyride controlled by someone with malicious intent.

The Internet of Things (IoT) brings convenience and automation, but it also introduces new security challenges. Here’s a breakdown of key measures to keep your connected devices safe:

  • Avoid sending sensitive data via open networks like Wi-Fi. Instead, build private networks for secure communication.
  • Utilize Virtual Private Networks (VPNs) with strong encryption for remote access.
  • Monitor your network for abnormal activity or attempted breaches.
  • Leverage cloud platforms that analyze connectivity data and identify potential threats.
  • Utilize IMEI locks to tie SIM functionality to specific devices, preventing unauthorized usage.
  • Encrypt data transfers using protocols like TLS to keep hackers in the dark.
  • Secure the gap between the application and the network with X.509 certificates or VPN/IPSec connections.
  • Deploy network-based firewalls to filter malicious traffic before it reaches your devices.
  • Monitor and block suspicious activity outside your VPN or restrict unnecessary functionalities.
  • Limit your device’s network access to its core functions. Restrict unnecessary features like voice calls or external SMS.

By implementing these measures, you can create a layered defense and keep your IoT devices safe in our increasingly connected world.

Protecting your IoT devices isn’t just about technology – it’s about collaboration. Businesses, device manufacturers, and security experts must share the responsibility to safeguard devices, data, and customers from ever-evolving cyber threats. Remember, security is an ongoing journey, not a one-time fix. Stay informed, collaborate with security experts, and together we can build a connected world where trust and progress go hand-in-hand.
