How Can I Hide Files And Processes In Linux?

Can any one tell me how to hide files and processes in Linux?for example, there is a *.exe file, I don;t want anybody to see it (just hide it),including use ls command.if I run this program, the process can be list by ps command.Is it possible to hide this process??if yes, how to do that??Thank you.

They easy way of hiding files is giving a dot at begin of a name, but they can still be listed (using ls -a)... I'm not sure, but take a look at some "Role-based Access Control" systems - like SELinux and GRSecurity... probably this would help you... maybe...

you can prevent un-privilaged users from vuiewing or running the file.you can prevent un-privilaged users from going inside a folder.but you cannot hide the file, there is no need to hide a file, except to clean up cluttered folders by hiding configs etc with the '.; char.as for hiding running processes, there is no reason you would want to do this.you seem to be talking about root kits, but thats a big no no here.

What you could do is add the file to a .ZIP archive and apply a password. That way no one without the password could access it.Is this intended to be malicious?
