Secure coding is the practice of writing programs that are resistant to attack by malicious or mischievous
people or programs. Secure coding helps protect a user’s data from theft or corruption. In addition, an insecure
program can provide accessfor an attacker to take control of a server or a user’s computer, resulting in anything
from a denial of service to a single user to the compromise of secrets, loss of service, or damage to the systems
of thousands of users.
Secure coding is important for all software; if you write any code that runs on Macintosh computers or on iOS
devices, from scripts for your own use to commercial software applications, you should be familiar with the
information in this document.
