HTTP Basic Auth has been with us for ages. Some despise it for its insecurity, while others love it for its simplicity. Should you opt for using it or avoid it at all cost?

Data integrity is rarely talked about, even though it comprises the basis of many data flows a modern web application has to deal with. From a security perspective, integrity deals with protecting data from being modified (by unauthorized parties). There are various techniques to ensure integrity. I will guide you through the options, using real world examples. Once you finish, you will know more about this than most of the industry.

Solid security knowledge among developers is scarce these days, simply because it is not as spectacular and sexy as a new framework or a cool new tech. Nevertheless, it is real and will not go away anytime soon. Your best bet is to start learning about it right now. It will make you more valuable to your team and your organization.
