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.
Addressing these IoT cybersecurity challenges and vulnerabilities becomes imperative as the Internet of Things (IoT) continues to get widespread adoption in our daily lives and industries. By enhancing cyber security for the Internet of Things, we can harness the full potential of this transformative technology while protecting user privacy and safeguarding against potential threats.
How to Safeguard IoT Devices Against Cyber Attacks
