How to securize SE16N

Hello,

I have securize SE16N with SAP OSS note which is checking SY-TCODE.

Currently if you trying to launch SE16N through SE37, SE38, SA38 SEU_INT or SE93, it checks if you are authorized to SY-TCODE = SE16N.

Despite that, I have still discover that some people have found another way to use SE16N despite my controls set up.

To definitly secure my system, I need to understand how they can proceed. Do you have any idea on how they can do.

The only trace I found in STAT is :

Transaction : SESS Program : RK_SE16N

Thanks for your help.
