Presentation Developing secure IBM i applications

The IBM i is one of the most secure system on earth, but even on the ibm i many mistakes can be made if you do not understand how security has to be implemented on the system. I have found a presentation which explains in detail how security works on the IBM i. This presentation was presented at the January meeting of the Utah IBM i developer association by Robin Tatam. I really recommend this presentation for every Sysadmin and Developer who is interested in security on the IBM i.
