Congratulations, you've reached the end of this first course in the secure coding specialization. Let's take a look back to all that you've accomplished. You've learned why robust and secure coding is so important, and what can happen when your programs are neither secure nor robust. You understand the basic principles underlying secure programming and how to spot non-robust code. You can take that poorly written program and translate it into a more robust secure program. You also now have a sense of how formal methods work, and how you can adapt the general philosophy and ideas from those into careful, secure, and robust programming. What we've done is placed secure programming in the broader context to both security and good programming style. We've explored design a bit and implementation a bit. The next courses, we'll show you some of the more pernicious security problems in programming and what risks they introduce, and then look at specific problems in the secure coding practices that thwart them in two very common languages; C#, which includes C++, and Java. These build on what you've just learned in this course. Thank you for participating in this course. We look forward to working with you in the next one.
