CSFI: Defensive Cyber Operations Engineer (DCOE)


CSFI: Defensive Cyber Operations Engineer (DCOE)

Develop your cyberspace operations skills for the deployment of DCO, NETOPS, and OCO.

In this course, you will acquire the skills for the planning, executing, and integrating defensive cyberspace operations (DCO) into organizational missions and DCO requirements. The course builds on the planning skills learned in the Introduction to Cyber Warfare and Operations Design (ICWOD) course. Adversarial use of tools and their associated techniques are presented to assess network vulnerabilities and to defend friendly networks against adversary threats.

The course covers the use of open source tools and websites for system configuration, penetration testing, and control testing. You will use Linux and Windows command lines and unleash an attack on target servers and analyze the results. Attacks and analysis of will expose you to live attacks in a controlled environment where students can see first-hand the adversary realm of possible actions, how to detect, mitigate, and counter such activities.


  • This course requires you to bring your own laptop preloaded with VMware Workstation 9 or 10.
  • In order to attain the DCOE certification, you must have an ICWOD completion certificate as well as pass the DCOE exam.
