Firstly, a disclaimer: no method or system can ever be entirely foolproof and secure all the time, and you should be aware of the correct security measures that you should apply for the programming task or context in which you are coding. I will put some links to other information resources at the end of this chapter. Having said that, CodeIgniter offers some useful techniques for reducing the chance that something can go wrong, for example, in this chapter are several recipes that can help reduce the chances of something untoward--however, you should always remain vigilant and ensure that you're building securely.
