So, imagine you have a secret treasure chest with lots of cool toys and cookies inside it. You want to keep it safe so no one can steal it.
You build a big wall around it to protect it. But sometimes, bad guys find a way to sneak in through the wall and steal your treasure.
To make it even safer, you want to put guards around the wall to catch any bad guys who try to sneak in. This is called IAST, which stands for Interactive Application Security Testing.
IAST is like having extra guards watching your treasure chest, but for your computer programs instead. It checks your programs for any weak spots that bad guys could use to sneak in and cause damage.
IAST works by interacting with your program while it's running, like a secret spy or a detective. It checks all the different parts of your program to make sure they are working correctly and not letting in any bad guys.
So just like you protect your treasure chest with a wall and guards, IAST helps protect your computer programs from sneaky bad guys.
