2.  Lack of Compliance

Let’s understand it by pipping into the use of IoT devices in our day-to-day lives. If you use fitness trackers, you must have noticed that Bluetooth remains visible after the first pairing. A smart refrigerator can expose Gmail credentials, and a smart fingerprint padlock can be accessed with a Bluetooth key with the same MAC address as the padlock device. These instances exemplify the potential threats of cybersecurity in IoT.

Below are some security issues in IoT devices from manufacturers:

  • Weak and easily guessable passwords
  • Usage of old operating systems and software
  • Insecure and unprotected data storage and transfer
  • Technical issues in the hardware

3.  Botnet Attacks

Cybersecurity for IoT devices is crucial since they are highly vulnerable to Malware attacks. They do not have the regular software security updates that a computer does. To perform a botnet attack, a hacker first creates an army of bots by infecting them with malware. Further, directs them to send thousands of requests per second to bring down the target.

IoT and cybersecurity should go hand in hand to avoid a potential attack. A botnet attack can easily cause a security threat to transportation systems, manufacturing plants, water treatment facilities, and electrical grids, which can threaten big groups of people.

For example, a hacker can create spikes in the power grid by triggering a cooling and heating system at the same time. If this attack is planned on a big scale, it can create a nationwide power outage.

4.  Data Security and Privacy Issues

Do you know that hackers did not spare a visionary like Elon Musk and a company like Apple, known for their proud security claims? If such data comes into the wrong hands, it will not only lead to loss of money but also compromise intellectual property.

According to Microsoft, 60% of employees believe IoT is one of the least secure aspects of their organizations. And less than 50% of organizations have deployed best practices specifically designed to secure their IoT and OT devices. DataProt states that 83% of organizations have witnessed improved efficiency by implementing IoT data security.

5.  Financial Crimes

Electronic payment companies that deploy the Internet of Things may experience a wave of financial crimes. It will be a challenge to ensure the timely detection of fraud.

Also, compliance and operational issues make it intimidating for all financial firms to launch new workflow models unless they improve their risk management strategies, including a rising threat of IoT security breaches.

6.  Home Invasions

You must be familiar with the concept of ‘smart homes,’ a by-product of IoT. Cybersecurity for IoT has become a huge issue regarding home automation. Due to unsafe devices and poor defense mechanisms, your IP addresses are trackable, making it easy for hackers to locate the device’s address.

7.  Remote Smart Vehicle Access

An IoT security challenge that is close to home invasion is the hijacking of your smart vehicles. This can lead to theft of personal data, vehicle theft, manipulation of safety-critical systems, etc.

Also, remote vehicle access can be subject to ransomware, as a hacker may demand a hefty fee to unlock the car or to enable the engine. These malicious intrusions are obviously a huge threat to public safety as they can cause accidents.

3.  Public Key Infrastructure (PKI) Strategy

A public key infrastructure (PKI) allows users to engage in secure communication, data exchange, and money exchange. This type of engagement is carried out using public and private cryptographic key pairs.

PKI ensures data encryption through two — asymmetric and symmetric encryption processes. In asymmetric, we need two keys, one key is the public key, and the other key is the private key. If something is encrypted with the public key, decryption can only be done with the private key and vice-versa.

On the other hand, symmetric data encryption and decryption are done with the same key. Data encryption and decryption ensure that IoT data security is maintained and the chances of data theft are reduced to the bare minimum.
