如何安全地使用cronjobs

Question

How should I secure my cronjobs from being visited by search engines/visitors that write the correct URL in the headline?

I have a cronjob, that is running every night, which transfers information to MailChimp, but if a user enters the URL correctly, he can make the cronjob run at anytime. How can I avoid this? :)

Hope you have some ideas.

Thanks in advance.

Answer 1

the files should be outside the web root, there's no need for them to be inside if they are only being called by cron. hope you are calling the file path and not the url?
