Don’t leave security until last

For me, the most important consideration that should be thought about is the security of the underlying data. Too many times I have seen apps created without the necessary thought about what protective measures should be applied to the data.

Is there a risk if any of the data that I’m storing can be seen by other members of the organization? Do I need to lock that data away somewhere that gives me the utmost control over what goes into it? Do I need to configure permissions for each row or record in a table? Or do I need to go lower than that and apply security to a column?

They’re all questions that you need to ask. Secure by design is a key development principle that we should all be working toward. Creating an app and then trying to shoehorn security in afterward is extremely difficult, as I guarantee you’ll need to go back and make some quite fundamental changes. Whether those changes are to the data source itself...
