Authentication failed!null

This strange error appeared after trying to login enterprise manager dbconsole. Error message clearly notes that there is an authentication problem but a user (me this time) who reads this error message normally thinks that he has entered wrong username or password. This is not the problem here, because when we enter wrong information on em login screen we see an error like:

Error
Your username and/or password are invalid.

So checked the log file '$ORACLE_HOME/hostname/sysman/log/emoms.log' and saw an error like:

java.sql.SQLException: ORA-28001: the password has expired

This indicates that the status of SYSMAN user is expired. (This is most likely caused by the profile of SYSMAN user). Check the SYSMAN user status.

Higlights From IOUG Data Security 2009

IOUG has recently published their valuable research on Data Security. Here are some suprising results from the report:

1- Over the past year, percentage of the company's, whose data been breached, compromised, or tampered was increased.

I just wonder what will be the future of this increase every year. Will it be 50%, who says their data has been breached, compromised, or tampered 20 years later?



2- IT Security spending over the past year was decreased.

I'm not sure that economic crisis is an adequate reason for this situation. I can't imagine the crisis when my company's 20 billion custemer information will be stolen.
