I have been slowly adding more security and privacy content to this site recently. I believe you can do a lot to protect yourself with a little bit of knowledge. Security guides like this from Motherboard are a good place to start. As they put it:
There are lots of things you can do to make it much more difficult for hackers or would-be surveillers to access your devices and accounts, and the aim of this guide is to give you clear, easy-to-follow steps to improve your digital security. There are, broadly speaking, two types of hacks: Those that are unpreventable by users, and those you can generally prevent. We want to help you mitigate the damage of the first and prevent the second from happening.
If you are looking into these things, the best place to start to my mind is with a password manager. My favourite is 1Password. If you want to go further, start looking at a VPN. I have also posted recently on data security and cloud storage.
