Cyberspace must be defended from cybercrime, just like our physical living environment must be defended from physical crime, as expounded by Oscar Newman in his book "Defensible Space".

Therefore, I disagree with Dr Sunny Goh's suggestion that the term "cyber defenders" be changed to a more active and positive term, such as cyber warriors, commandos or fighters (Choose name that shows cyber enemies we mean business; March 21).

Deterring criminals from committing crimes should be the main aim of the defenders.

The more aggressive terms suggested are more appropriate for attackers, not defenders.
