Spotlight on IoT security issues

In the realm of IoT-based devices there are many players which interact in the IoT setting like gateways, sensors, communication protocols and the intellectual cloud backend servers. The journey starts with sensors sending information to the gateway through communication protocols, then it reaches the cloud through Lan or WiFi then it is processed for the detailed analysis and hence the report is generated and is visible on the smart. According to the source from Simplilearn, there would be more than 80 billion IoT devices by 2025. This is the promising facade of the IoT devices. There is another facade related to the security of IoT devices. The question arises in the minds of the people that how to gain knowledge about the internet of things security risks?

The risk is an inherent part of everything, even the disruptions in the technology have seamless as well as negative sides. IoT securities include the practice to safeguard the devices from the potential threats. The gamut of IoT security issues has a include:

  1. Device attacks
  2. Threats in softwares
  3. Threat of Distributed Denial of service
  4. Manipulation of Information
  5. Lack of Authority

There are many other threats are there in the ambit which penetrate into the devices and harm a large number of people. There is a huge tank of data on the server and if the attacker accesses the data and manipulates it then it will be detrimental for the people and the organization. The security issues are there in many Industries like Healthcare, where the device gets hijacked, the patient’s information can be leaked and many other things could happen. IoT security issues can be present in Finance, Automobile, Manufacturing, Retail and even at homes. It invades data privacy and is prone to vulnerabilities.

 

IoT device security- A rock bottom

The rise of IoT-enabled devices pampered the users with its seamless functionalities and also IoT network security is an important concern amidst the blazing Internet of things security vulnerabilities and challenges. When we say rock bottom, by this we mean that we are using IoT devices, but its security is at stake and the organizations and people at large hit the rock bottom i.e their IoT data communications are less secured and are on the lower level. Safeguarding IoT systems and devices is imperative to establish an element of trust and security among the stakeholders whose information is at risk. Let us discuss the top IoT security threat in detail.

  1. Distributed denial of service (Ddos):

    These involve interaction between the attacker and a server and it includes multiple devices and the attacker can build a virus which invades into any file which the user downloads and it leads to malfunctioning of the IoT based systems and devices.

  2. Unauthorized behavior:

    This involves unauthorized use of the credentials and fetching access through malicious attempts. The attacker obtains credentials of the valid user and can tamper with the files of the devices in the disguise of the valid user.

  3. Information manipulation:

    Data and information are primitive while using IoT devices. If an unauthorized person accesses the information which is crucial and manipulates it, then it can jeopardize the functioning of the systems and will be a threat to the organizations and people at large. Many Industries are vigilant about this and preserve the crucial data and information related to personal habits of the customers in order to protect customers from the threats.

  4. Device hijacking:

    According to the article by the Journal of Cyber security and mobility, to establish a high level of cyber security in IoT devices, and to address the potential threats, attacks and vulnerabilities, the system components that make up IoT should be necessarily identified. Any malfunctioning should be mitigated. Device hijacks should be prevented. It can happen to sensors being malfunctioned by an attacker and leakage of crucial information could arise. So it is important to prevent device hijacking and to boost confidentiality.

  5. e. Threats in software:

    In the purview of Internet of Things security vulnerabilities and challenges, there are three types of vulnerabilities- Hardware, Software & Technical. Hardware vulnerabilities are obscure and difficult to fix due to compatibility issues, software vulnerabilities include execution and malign activities in the operating system by the intruder, tampering the applications, control and communication protocols. Technical vulnerabilities include tampering with the requirements of the project, lacuna in the understanding of the policies, compliances and procedures used in the IoT systems etc.

These are main security threats that need to be addressed and identified to protect the privacy and security of the IoT based systems.

 

How to safeguard IoT risks and challenges

The main goal for every organization is to protect the privacy of its stakeholders which includes users, employees, customers, general public and Government. In this action we will walk through in detail regarding how to secure IoT devices and how to safeguard IoT risks and challenges.

  1. Following Compliance:

    The prima facie thing which global IT leaders should follow are the compliance standards which include IP, IPv6, Zigbee, Z-Wave to name a few along with the auditing and controlling mechanisms.

  2. Automatic identification:

    Several companies in Healthcare, Fintech and other industries should invest in IoT security which helps in automatic identification which helps companies to inspect devices on their network and unmanaged devices can be disconnected easily through tracking and control so that the devices are checked before they join the network.

  3. IoT devices maintenance:

    This includes updating the IoT devices regularly, with latest security updates, protocols to ensure safety of the data generated by the IoT devices. Maintenance on a regular basis makes IoT security in devices and deter hackers from unethical activities. Thereby ensuring a high level of security at offices and even homes.

  4. Trusted mechanisms:

    Several mechanisms are there to protect the data communication like using SIM (Security Information Management) and crypto-sage features to solve the IoT challenges.

  5. Stop avoiding plug and play:

    Avoid using plug and play feature because it will protect the system from the high chance of outside attacks intruding the multiple devices that are connected.

  6. f. Other important measures:

    Implementing security by design to protect devices from dangerous flaws, having a security operations center to accurately respond and manage the security accidents, partnering and liaising with security experts to mitigate IoT challenges and issues.

 

Why safeguarding IoT security is pivotal?

Safeguarding IoT security is pivotal because if the system gets succumbed to malware then any attacker can sabotage the important data and manipulate it through despicable means. Some specialists and experts predicted that there would be a possibility of IoT generating more than $ 13 trillion in terms of revenue by the year 2025. This enormous scope brings risks, data privacy, security and Governance concerns. These elements should not be at stake. In order to safeguard these elements, the organizations should construct a strategic IoT security layout in order to preserve security and eliminate breaches. The plan should include giving a vivid notice into the website of how their data is used and shared. Following the full disclosure method can create a stakeholder credibility. To ensure great transparency, code of ethics, good governance and trust, a proper Risk management plan should be chalked out by the IT managers which should align with the organizational goals and involve all stakeholders in the plan. So that they will be aware of the potential risks and can respond well during the event of the security crisis.

 

Conclusion

In a nutshell, we can say that safeguarding security in the IoT universe is equivalent to safeguarding privacy of data as well as preserving humanity at large so that any mishap is identified timely and the IoT security issues can be corrected accurately using Risk management protocols by involving clients, end users, employees and general public at large. With the surge in the IoT based devices, there must be a surge in the compliance and security protocols to keep attacks at bay. Hail Iot, hail security and hail humanity!
