Tasks and responsibilities

To give you a better idea of what the job entails, here are some tasks and responsibilities found on real security engineer job listings on LinkedIn:

Security engineer vs. security analyst

Both security analysts and engineers are responsible for protecting their organization’s computers, networks, and data. While there might be some overlap in their tasks, these two jobs are distinct. 

Security engineers build the systems used to protect computer systems and networks and track incidents. Security analysts monitor the network to detect and respond to security breaches. Many security engineers start out as security analysts.
