The daily cyber security engineer activity goes like this:

  • Conduct a thorough study of potential risks and threats and analyze their implications at the technical level.
  • Identify and integrate security solutions into products or technical prototypes based for example on PKI architectures (Public Key Infrastructure) protected by hardware security modules (HSM).
  • Use secure elements offered by different suppliers of electronic components (e.g. : Infineon, STMicroelectronics or NXP) and integrate them with embedded cryptographic libraries.
  • Develop on electronic boards with one or more microcontrollers.

It should be noted that the cyber security engineer is involved in the product implementation phase to set up protection processes; whereas the pentester will test the final product security.

How to become a cyber security engineer

To become a cybersecurity engineer, you must ideally be a graduate of an engineering school with a specialization in cybersecurity oriented computer science, or an equivalent university degree.

Required Skills

The cybersecurity engineer has wide skills.

He / She:

  • Is capable of translating cyber security issues at the technical level. This implies solid knowledge in network, computer security and electronics.
  • Has advanced skills in embedded software development (e.g. : in C).
  • Has a good theoretical knowledge of cryptography and is able to implement cryptographic mechanisms using dedicated software libraries (e.g. : Mocana, mbedTLS and wolfSSL).
