Top 5 IoT security threats and risks to prioritize


The Internet of Things (IoT) is a system of networked machines and items, digital or mechanical that may transport data over a network without human contact. An IoT system can be any device that uses an internet protocol (IP) address to send data over a network, such as a car with built-in sensors that warn the driver of low tire pressure, a biochip transponder implanted in a farm animal, a heart monitor implanted in a human, or any other item.

IoT is used by businesses to provide better customer service, boost decision-making, raise the value of the company, and run more smoothly.

IoT Security Issues

Users of IoT devices may be at risk of a data breach as a result of the issues described below.

Physical security is lacking

Attackers occasionally can physically alter IoT devices that are placed in remote locations for extended periods. They can, for instance, spread malware to USB flash drives. Device physical security must be ensured by IoT  application solution company in Chennai while  device manufacturers. However, it can be difficult for manufacturers to create safe transmitters and sensors for low-cost IoT.

Botnet assaults

A group of computers that have malware on them is known as a botnet. Attackers make thousands of requests per second to a target using these compromised machines to bring it down. Because IoT developers in Chennai by devices do not receive regular security upgrades as traditional computers do, they are extremely susceptible to malware attacks. Attackers can thus quickly infect IoT devices to transform them into botnets that can transfer massive volumes of traffic.

Inadequate visibility

IT teams have a difficult time gaining insight into all IoT development company in Chennai by devices on the network since many of them are just not listed in IT inventory records. IT teams believe that equipment like smart coffee makers, ventilation, and air conditioning systems is not “critical enough” to be tracked. If security teams are unable to see what is linked to the network, they are helpless to stop breaches.

Data security

IoT security is seriously compromised by data privacy. Numerous gadgets gather user data, such as patient information from medical equipment and private data from smart toys and wearables. For instance, hackers may take control of a security camera to spy on its owner before using the footage against them. Hackers may also gather business information to expose, sell, or extort the owner.


Attacks using ransomware encrypt and restrict access to private files. The hacker will then demand a ransom payment in exchange for the key needed to decode the files. Poorly secured IoT devices might also be the target of ransomware.
Ransomware attacks on IoT devices are relatively uncommon. However, because of their increasing importance to their owners and dependence on them as mission-critical systems, smart homes, medical equipment, and other smart devices may be in danger in the future.

Solutions for IoT Security

Cyberattacks could target any connected device. Make careful to heed these recommendations to fend off future assaults.

Implement IoT security analytics

IoT security concerns and vulnerabilities can be considerably decreased through security analytics. By gathering and analyzing data from many sources, security analytics assist security teams in identifying and preventing potential risks.

Additionally, by combining information from several domains, security analytics can spot harmful anomalies in network traffic. Security teams can address these anomalies and stop them from adversely affecting connected devices thanks to the correlation. Analytics can quickly identify spike-related sensor security problems. Together, all of this important data may be used to identify dangers and efficiently stop them.

Endpoint Response and Detection (EDR)

IoT devises stream data continuously, thus every second you are not in charge of them, you are losing data. You can prevent losing this data and spot threats in real time with the use of EDR technology. With real-time visibility and alerting, EDR enables security professionals to swiftly spot malicious activities and gain direct access to devices.
The capacity of EDR to automatically prohibit suspicious activity in real time is another important feature. Even if human security professionals are unable to react promptly to the occurrence, EDR solutions use threat intelligence to recognize suspicious activity on an IoT device and execute an appropriate reaction.

Safe APIs

IoT devices frequently use APIs to exchange the data they collect and obtain data from other systems. Many security plans have a weak point that involves APIs. Organizations may prevent hackers from accessing their IoT devices through improperly configured or unauthenticated APIs by implementing API security best practices and ongoing security testing.

Increasing the visibility of the network

To keep a complete inventory of all network-connected devices, IT teams require specialized visibility technologies like network access controls (NAC). When a new device joins, NAC technology should immediately update the inventory and periodically validate it. Organizations can take security compliance activities and automatically respond to security problems by keeping track of IoT devices.

Encrypted communication

Attackers can access devices by interfering with IoT communication. To prevent data breaches, you must encrypt communication between IoT devices and interfaces like web apps and mobile apps. SSL/TLS is now the most popular encryption mechanism for data transit.


IoT device vulnerabilities can be decreased thanks to comprehensive device authentication because hackers are constantly looking for ways to access personal data. For Internet of Things (IoT) devices, several authentication methods are available, including biometrics, digital certificates, and multifactor authentication. Making sure that unauthorized individuals cannot access your devices is essential.


The viability of networks, devices, systems, and users is threatened by insecure IoT devices. But company configuration is not the only factor in IoT security. Users and administrators should work together to establish a security culture to adequately safeguard IoT. This requires users to follow fundamental security best practices, such as preventing unauthorized remote access and altering default security passwords.

Device manufacturers ought to adopt a more comprehensive strategy and spend money on visibility, security analytics, and encryption. Systems and administrators should keep an eye on activities and act immediately. Together, these top IoT companies in Chennai administrators, users, and manufacturers can guarantee IoT security.
