I'm currently writing an in house coding challenge web application and I am wondering if there is any other security precaution I would need to have other than below java option at runtime.

java -Djava.security.manager=default

Basically, challenges would be more of single threaded math and algorithm focused. So I would need to enable basic data structure objects and disable any file, sockets, threading or any thing that might be not so important.

Based on my quick search turning on security manager as above seems to be a solution but since this is a security related I would like to be sure before it goes alive.

Is there anything else I could do more?
