Mainframe, MVS and zOS Discussion

Hello,

Is there any way I can protect a data set from over-writing? Actually, I want to secure a sequential file that I have created, in a way that no one else can delete or overwrite it. Is it possible to do ? Please help.

security issues should be discussed with Your security support 

 You can use the site security package to control access to your data set.  However, you need to talk to your site support group as there may be site restrictions.
