+### Security
+
+The following features provide you with a secure, sand-boxed environment to run user scripts.
+
+- Define memory limits, to prevent allocations from depleting the memory.
+- Enable/disable usage of BCL to prevent scripts from invoking .NET code.
+- Limit number of statements to prevent infinite loops.
+- Limit depth of calls to prevent deep recursion calls.
+- Define a timeout, to prevent scripts from taking too long to finish.
