What is Object Level Security in Salesforce?

Many thanks!
Can you please explain how to hide report pages from some staff groups?

Hi my suggestion is from next time if you guys conduct any sessions then please don't allow the students or participants to speak while explaining the terms,its really messes up the things..anyway content is really nice..thanks for the content

Great explanation Shubham

very informative session. i have a request here,Can you please make videos related on Teams and Territory for security . And it would be great if we have some sessions on lighting navigation .Thank you
