The NIST and CIS baselines don't allow su, we have to use sudo on government computers.
Could you enlighten me on the rationale behind that restriction? As, as you already noticed, my [ancient, maybe] reasoning makes me arrive at an opposite conclusion. (but mine is pure security consideration with full trust vested into sysadmin, see below...)
On a second guess: it is just for a separation of privileges, and accounting of who did what which sudo brings to the table... Right?
Thanks in advance. Valeri
