SQL injection and security implications – final comments
Now that we've explored SQL injection through this book, we can talk about SQL injection and security issues in today's world, all while considering the implications in terms of security in the World Wide Web and the repercussions in the real world.
SQL injection in today's world
SQL injection is indeed an old and well-known vulnerability and, as such, it is usually taken into consideration when developing or releasing new applications, especially in the World Wide Web as web applications. Most basic attacks are usually ineffective due to the fact that most common countermeasures are usually applied to the vast majority of cases, and many web frameworks with built-in controls are often used. However, it may happen that vulnerable applications still exist, often due to bugs and oversights in the source code, or some other unforeseen condition.
