Oracle Secuirty Tips / SQLNET.ORA Part 2

Posted on by Osama Mustafa in Database
Hi All ,

I post before about sqlnet.ora with parameter called invited_list , Exclude_list , assume  that i want to prevent sysdba to access database without password Simple Way .

SQLNET.AUTHENTICATION_SERVICES=NONE 



Setting “SQLNET.AUTHENTICATION_SERVICES” parameter to “NONE” in sqlnet.ora file will make it not possible to connect to the database without a password as sysdba. (sqlplus / as sysdba)

This parameter may also have the values : NTS for Windows NT native authentication, ALL for all authentication methods.

Authentication Methods Available with Oracle Advanced Security:

  • kerberos5 for Kerberos authentication
  • cybersafe for Cybersafe authentication
  • radius for RADIUS authentication
  • dcegssapi for DCE GSSAPI authentication

If authentication has been installed, it is recommended that this parameter be set to either none or to one of the authentication methods.

Enjoy

Thank you
Osama Mustafa
