How secure is a runtime?

[dubl]

If you strip administrator privileges from a runtime, how secure is it?

Data such as registration details, time-bomb dates etc - could they be hacked?

Anything can be hacked.

If you strip administrator privileges from a runtime, how secure is it?

I haven't yet heard of a hacking tool that will let a user add back in the administrator privileges to a runtime that was stripped of them. As far as I know it would require a tool to modify the binary code in a complex way.

Data such as registration details, time-bomb dates etc - could they be hacked?

How easily these details can be hacked is entirely dependent on how they are implemented. Some methods are trivial to hack. Some require a lot more effort and additional software tools.

There is never a hacker-proof solution. There is only different levels of hacker/tamper resistance. What level you choose depends on where you want your solution to fall in the spectrum of security versus convenience. The more secure your solution is, the less convenient it is for you to manage and for your users to install and use.
