Ransomware is the most serious threat in the digital world right now. There were an unprecedented amount of ransomware assaults in 2021, and this trend is expected to continue into 2022. The Internet of Things, sometimes known as IoT, is the most vulnerable to data security risks. IoT refers to any digital, mechanical, computer-smart device that can communicate data over an internet network, such as a laptop or a mobile phone. Hackers utilise gadgets around you, such as wearable smartwatches, baby monitors, smart fridges, or smart lighting, to gain access to your personal device, which carries sensitive information. This is yet another significant obstacle. Another major cause of compromised data security is a lack of encryption, authentication, and poor cloud settings.
