    What is your attack surface, i.e. is it your local machine? a LAN? your entire home? data over the Internet? A worldwide enterprise? That determines how much you have to do

    What is the value of the data? Does a hacker care about Joe Schmo? Probably not. But do you have confidential company data, or are you an important stakeholder? Well, now you've suddenly become a bigger target

    How much time, money and effort are you willing to put into your security? Remember, there are entire companies dedicated to security, and entire SOC's whose sole job is monitoring for security incidents and even they don't catch everything. These organizations have multiple experts, layers of defense and constant monitoring, but the data they protect is worth it (see #2 above). How much effot you're willing to put in determines how many steps you need to take.
