For the Cybersecurity field, I would also advice to join some of the Cybersecurity (offsec and defsec) discord channels, and generally the communities surrounding CS. There you can at least scope the topics. As for finding a entry level Cybersecurity job; I don't think that blogging is a good route to take, unless you really have some skills to show off. But I do see companies hiring people right after attaining certain certificates + being active in online communities.
