Strong encryption techniques that protect data transmission between devices can be implemented by data analysts to guarantee the digital security of IoT systems. To make sure that only authorised users and devices may access the network, they should implement secure authentication methods like OAuth or TLS. Using analytics tools to regularly monitor IoT networks for odd trends or anomalies can assist in quickly identifying and mitigating security concerns. To safeguard sensitive data, analysts should also use data anonymisation techniques and make sure that software and hardware are updated often to fix vulnerabilities.

Enrolling in a specialised data analyst course from Coursera or Udacity can help you gain experience in this field.
