What is the difference between data owner , data custodian and system owner

I just started studying up for the CISSP and am having trouble understanding few concepts.

  • Data Owner
  • Data custodian
  • System owner

Somewhere I read

The data owner (information owner) is usually a member of management who is in charge of a specific business unit, and who is ultimately responsible for the protection and use of a specific subset of information.

The data custodian (information custodian) is responsible for maintaining and protecting the data

But in practical world, what exactly is the boundary for these roles? Both seems to be protecting data.

Any real-time example helps.

Retired ecommerce owner

Hi everyone,

I wish I found this community earlier in my journey.

I happily sold my ecommerce business few months ago, before the competition crushed it, and I am now retired.

I set up new projects in my spare time, mostly online.

Happy to be here,

Have a nice day!


Need help to fix owner, groups and user permissions in Xubuntu 16.04.6

Some time ago I messed up my system users and groups permissions, now I can’t run users-admin command, the output is : the owner of /home/vladimir/.config/ibus/bus is not vladimir!(the owner is root), if I change to vladimir I got the same output displaying that the owner is not root. I can’t modify anything on users and groups GUI, when I try to modify any setting immediately open and close several windows so fast that I can’t read what’s going on! Appreciate some help, I have one user added long time ago.

How to get Site Owner Via Graph

I’m attempting to get site owners via graph.

Documentation indicates this should be possible via /sites/{site-id} via /sites/{site-id}. I’m using beta.

The problem is I’m not even getting a blank owner attribute; I get everything else.

I’m curious if anyone has tried/confirmed this is working or not. I’m also curious if there is an alternate endpoint to retrieve owner info via graph.
