This chapter was all about why you need to learn operational security. We covered what proactive, reactive, and operational security mean, the significance of those pillars, as well as what a Security Operations Center is and why you need to understand it.
While this chapter focused on the operational and technical aspects of cybersecurity, the next chapter will throw some light on the importance of human elements, such as if you want to choose any career, how to pick a mentor in your field. We will look at the importance of interpersonal networking, because security is never achieved alone, and you will need information and contacts to get important information, guidance, or even land a job.
