Hi,

Yes, it's a good idea to update iOS on your iPhone to get the latest security updates and possibly new features.

Necessary? No. Advisable? Definitely, for security reasons alone.

As others have mentioned, it is good to update for security reasons. It is also good to update so you get the latest bug fixes.
