Security for the Internet of Things

The Influence of IoT on Safety

IoT is a dynamic domain and its rapid evolution poses a challenge for network security. This exposes a plethora of security threats, given that IoT devices transmit their collected data to a central depot through the internet. A diverse range of IoT devices are currently accessible, including smartwatches, smartphones, fitness trackers and gaming consoles.

The inadequacy of the existing security measures embedded within IoT networks is extremely evident in the face of contemporary cyber threats, leading to the call for periodic enhancements. This highlights the susceptibility of IoT networks while underscoring the criticality of sustained security updates.

IoT could possibly create security vulnerabilities. For instance, even a rudimentary fitness tracker can furnish a hacker access to personal information such as account numbers, ATM codes and PINs, since it can monitor hand gestures incessantly.

Instances of hacked smart security locks that permit unauthorised entry into households, accessing connected vehicles, disengaging brakes, as well as medical equipment being hacked such as insulin pumps which could hinder the administration of medicines, all serve as indicators of grave security risks.

Data breaches within IoT networks pose a significant concern, given the potential for far-reaching, physical implications in addition to unauthorized access to sensitive user data, if not managed appropriately.

Primary Security Challenges Encountered by Internet of Things Devices

Ensuring the security of Internet-of-Things (IoT) networks is a critical concern, as these devices interact with multiple networks and other devices in various manners. Regrettably, they are vulnerable to security defects that could expose them to intrusion or data breach attempts. Listed below are some of the gravest challenges related to the security of IoT networks.

  • Distant Accessibility:

    IoT devices employ advantageous wireless networks or Bluetooth connections. Nonetheless, this makes them prone to cyber security threats, because hackers could conceivably gain access to them remotely.
    A large network of devices has a significant number of possible entry points that a hacker can exploit. Phishing campaigns are one of the most common tactics hackers use to get access to IoT devices through malware software or redirection to malicious websites.
  • Limited Processing Time:

    Some IoT devices have been noted to have inadequate processing capabilities, making it impossible to support the execution of security software such as antivirus or firewalls. Also, some devices face connectivity difficulties with other devices. Since there is yet no effective method for safeguarding these devices from malicious attacks, they form a significant security threat to IoT networks.
  • Dearth of Expertise in the Business Sector:

    The extensive proliferation of information and communication technologies around the world has ushered in a wave of digitalisation across industries. As companies leverage Internet of Things (IoT) devices to optimise productivity and operational efficiency, a host of challenges have emerged as well.
    The problem is that most industries fail to prepare for when things go wrong with all this new technology. There’s a lack of industry foresight regarding potential hacker attacks and data breaches.
  • Viral Spread:

    Cyberattacks often involve employing compromised systems to infect other devices within a network. Internet of Things (IoT) devices have seen an upsurge in their use within distributed denial of service (DDoS) attacks. The primary objective of such an attack is to overwhelm the target with traffic, rendering it inoperable. Hackers intensify the impact of these attacks by planting malicious code on nearby devices and using them to proliferate the assault.

A Possible Security Vulnerability in Baby Monitors

A recent incident brought to light the potential security hazards relating to Internet of Things (IoT) networks with respect to baby monitors. The concerned parents were startled to discover that an unidentified third party had gained access to their baby monitor, conversing with their child.

The incorporation of Internet of Things (IoT) devices is at the vanguard of progress in parenting. Baby monitors, healthcare apps, pacifiers linked to mobile applications aimed at monitoring an infant’s body temperature, as well as garments that track body temperature, sleep postures, and other patterns, are on hand to new parents.

As the internet of things grows, there is a potential for hackers to manipulate children’s personal information. The scope for misuse is vast, from acquiring personal addresses to streaming video feeds from security cameras.

This raises the question of how to protect IoT systems and devices from future attacks.

Securing IoT networks poses a complex challenge, necessitating businesses to perpetually devise new tactics and technologies to guarantee triumph. Nevertheless, there are actions that customers can adopt to mitigate the likelihood of vulnerability to potential threats.

  • Regularity in updating devices with the latest security patches and upgrades is crucial. Failing to do so may unknowingly expose users to possible security hazards. As a preventive measure, it is advisable to ensure devices are frequently updated and patched.
  • Generating complex and distinctive passwords is crucial to preserve cyber security. Vulnerabilities arising from weak passwords form the basis of numerous cyber-attacks. Therefore, it is vital that passwords are robust, unique and stored securely to safeguard all accounts against potential threats.
  • Ensuring the adequecy of your wireless network’s security is crucial. Public Wi-Fi networks are viewed as hazardous as anyone can join them. Similarly, private Wi-Fi access points can pose a risk if not amply protected. To mitigate this risk, it is advisable to use robust Wi-Fi passwords and activate the router’s firewall.
  • It is recommended to establish a dedicated network for IoT devices, which is segregated from other systems. This will help minimise the risk of cyberattacks on the IoT and prevent harmful traffic being transmitted to other systems.
  • Appropriate management of GPS usage is fundamental in prioritising user safety. The Global Positioning System (GPS) is extensively employed in many Internet of Things (IoT) devices, and in the event of them being hacked, user safety can be severely compromised. To mitigate potential risks, it is advisable to limit the use of such applications and control GPS access.
  • Giving consideration to the Internet of Things (IoT) protocols is crucial. IoT devices may communicate with one another via more than just the internet, such as Bluetooth and Near Field Communication (NFC). To be prepared for potential security hazards, users ought to be aware of the diverse protocols used by their devices.
