Mention any three security challenges in Internet of things? ?

1. Privacy concerns: With the vast amount of data being collected and shared by IoT devices, there is a risk of personal information being compromised or misused. This can lead to identity theft, fraud, and other privacy violations.

2. Lack of standardization: The IoT industry is still relatively new and lacks standardized security protocols. This makes it difficult for manufacturers to ensure that their devices are secure and leaves them vulnerable to cyber attacks.

3. Vulnerable devices: Many IoT devices are not designed with security in mind, making them easy targets for hackers. These devices often have weak passwords, outdated software, and lack encryption, making them susceptible to being hacked and used for malicious purposes.
