Secure vs. Insecure, Scripts
 

Can someone knowledgeable on the subject give a detailed explanation of what makes a script secure or insecure?

i guess scripts that are clientside and can be editted easily by someone using a program

He said knowladge able, not guesses..

Unsecure scripts are the ones that can be "hacked" from the clientside.
If you, for example, use a triggeraction to a weapon to warp clientside, it is most likely unsecure. Client. strings for importaint stuff like stats and health are also unsecure.

It's not like you can't use triggeraction, but it must have proper and secure conditions serverside.
