Can somebody please help me to know if below required infos are logged or not? If yes, how can I get them?

  1. Successful and failed authentication attempts
  2. Use of root privilege accounts, such as through su and sudo
  3. Denied inbound connections, e.g. those blocked by packet filter
  4. Command and shell history

(PS: I am a beginner)
