What Does a Security Engineer Do?

Security engineers are a vital part of any tech company. They implement and enforce security policies. With adequate policies in place, it’s been up to the security engineers to maintain, monitor, and apply countermeasures, mitigation, and other infrastructure to secure the system. The security engineer is responsible for creating and developing incident response actions and guidelines. 

Security engineers have to think a step further when securing systems and storing data. If you apply for a security engineer role, you must focus on securing its intellectual property held in network and IT places. It will be you who will deal with physical security, such as cyberattacks or other security. 

Must-have Skills to Become a Security Engineer
