How to Apply Security or Remove in Batch using Acrobat X

I’m using Acrobat X Pro. I’ve used Acrobat Pro 6-9. I need to remove security in batch and apply security to about 100 PDFs. I’m totally lost in Acrobat X. Where are all of the batch sequence commands that were in Acrobat 9? Can anyone point me to an article or tutorial on batch sequences and the new “Action Wizard”.

Thanks.
