Azure has just introduced another tool to help in the fight against SQL injection known as SQL Database Threat Detection. You can go and read all the Microsofty bits there or watch it work in a real live app here.
Firstly, this is threat detection, not prevention. In a nutshell, this feature will tell you when an attack is mounted against your database and in order to do that, the upstream app has to have a vulnerability in it that’s allowing the attack to get that far. Now before you give it a bit of “well that’s pretty useless then”, the main reason this makes sense is that you can go and enable it with a single checkbox tick and it won’t break your things. Plus, even if the code is solid and you have a device or a service like a WAF, this is just one more layer that’s good to have in place. Let’s just jump into it.
This is a useful tool. If you’re using Azure SQL Databases, go forth and activate this.
