Is It Possible To Prevent an OS Authenticated Oracle User To Connect via the command "SQLPLUS / AS S

in Database Networking (MOSC) 3 commentsAnswered

Hello Team


As we know connect / as sysdba would not use the password file and it use os authenticate only (os groups), to prevent from this we use SQLNET. AUTHENTICATION_SERVICES=NONE in sqlnet.ra file , hence DBA can modified this parameter file if he has required permission on particular file.

for security concern is there any solution for this

and also what if we change the ownership of file to root and gave read only to oracle users/DBA is there any issue for users connected to Database, suggest how to prevent direct sys login in database without AUTHENTICATION_SERVICES

Howdy, Stranger!
