The ever-changing world is witnessing a rapid surge in technological connectivity, primarily propelled by the proliferation of Internet of Things (IoT) devices. This interconnectedness has opened doors to remarkable advancements in medicine and the development of products that enhance the human experience. 

However, alongside technological progress, cybercrime methods have also evolved. One significant manifestation of this is the increasing number of IoT device hacks. Exploiting the often fragile and neglected security measures surrounding these devices, malicious hackers now focus on the vast array of internet-connected gadgets. 

Consequently, there has been a soaring demand for cybersecurity professionals, specifically Ethical Hackers, who specialise in safeguarding IoT devices from malevolent attackers. As society grapples with the challenges posed by this emerging threat landscape, the role of Ethical Hackers has become indispensable in ensuring the protection and security of IoT devices in this interconnected era.

In this article, we will explore ethical hacking, its role, responsibilities, and importance in the future.

What is Ethical Hacking?

Ethical hacking is a legal practice of identifying vulnerabilities in applications, systems, or organisational infrastructures. Its purpose is to bypass security measures and discover potential data breaches and threats in a network. Ethical hackers systematically investigate weak points that could be exploited by malicious hackers, analysing information to enhance system security and resilience. 

Unlike malicious hacking, ethical hacking is authorised and planned, allowing cybersecurity engineers to test defences and develop solutions. Organisations can prevent data breaches and protect sensitive data by employing ethical hackers. These experts focus on areas like injection attacks, security setting changes, data exposure, authentication breaches, and potential access points in the system or network.

Why are IoT Devices Vulnerable to Cyber Attacks?

IoT technology is relatively new and often lacks robust security controls, leaving these devices vulnerable to malicious attacks. The absence or fragility of security measures in IoT devices creates significant risks. These risks include weak passcodes, unsecured data storage or transfers, delays in security updates, and the absence of proper update processes. 

A major security concern is the widespread knowledge of default passwords for IoT devices, making them easier to compromise. Moreover, unsafe communication is a significant risk factor, as data is frequently stored and transferred without encryption in many IoT devices. These vulnerabilities expose IoT devices to potential hacking and compromise of sensitive information.

Why is Ethical Hacking Important?

Ethical hacking is vital for all organisations due to the value of information and data. It helps protect sensitive data, ensuring privacy for both organisations and customers, making it crucial for safeguarding valuable assets. 

Here are the reasons that highlight the importance of ethical hacking:

• Data Privacy: In the digital age, organisations must prioritise the security and privacy of their valuable data.

• Security Testing: Ethical hacking is extensively used to test and identify vulnerabilities in security systems, ensuring they are robust and reliable.

• Bug Bounty Programs: Many companies offer bug bounty programs, where hackers are rewarded for identifying technical bugs and security vulnerabilities in websites and applications.

• Data Protection: Ethical hacking helps secure crucial data and prevents users from exploiting organisations or individuals, reducing the risk of blackmail or unauthorised access.

• National Security: Ethical hackers protect nations from cyberterrorism and prevent terrorist attacks. Government organisations often employ ethical hackers for privacy protection.

• Attacker’s Perspective: Ethical hackers can think like hostile attackers, identifying potential entry points and security vulnerabilities.

• Assistance to IT and CS Systems: Ethical hackers provide security assistance to various domains, including software development, risk management, quality assurance testing, and network defence.

• Functionality and Testing: Ethical hackers ensure software functions smoothly under standard and extreme security conditions, developing testing tools and methodologies to prevent similar situations in the future.

• Unparalleled Need: Organisations dealing with information products, applications, and websites greatly benefit from the expertise of ethical hackers.

Roles and Responsibilities of Ethical Hackers

Ethical Hackers are professionals who assess the security of IT networks without harmful intent. In the context of IoT devices, they play a crucial role in defending against potential attacks. 

Ethical Hackers gather information about their target IoT devices, scan for vulnerabilities, and launch various attacks to test the system’s defences while focusing on covering their tracks. Their responsibilities include:

• Vulnerability Assessments: Ethical Hackers use tools and approaches to identify security flaws in IoT devices, ensuring potential threats are detected and prioritised.

• Awareness of Attack Techniques: They stay updated on the tactics employed by unethical hackers, such as phishing, social engineering, ransomware, DoS, DDoS, and malware attacks.

• Understanding IoT Threats and Risks: Through threat modelling, Ethical Hackers analyse the most common vulnerabilities and risks associated with IoT devices. They rank risks, recommend security measures, and take appropriate action.

• Simulated Cyberattacks: Ethical Hackers conduct simulated cyberattacks, including brute-force, ransomware, DoS, and malware attacks, to identify weaknesses in IoT devices and infrastructure.

• Enhancing Security Measures: They develop strategies to improve the security posture of IoT devices, such as implementing firewalls, antivirus software, and password policies.

• Education and Training: Ethical Hackers educate employees and organisational members about IoT vulnerabilities, risks, and defensive measures. This empowers them to protect themselves from cyberattacks and respond effectively in case of an incident.
