Actually that is what he mentioned that they do not mention about security there, due to confidentiality reasons, that part of GCMS is kept blank.
So maybe if your security is not started by then, they may mention not started but not anything else, or maybe that is kept blank again due to confidentiality reasons. As much i have read about it, it seems its CIC s call on this and mostly they keep it blank.
But I think you should not be worried much about security here, if one is a good moral citizen and have had no connection to any fishy organisation etc., nothing to worry about security. You will be fine.
