Mary Ann Davidson: Applications will have to defend themselves from attacks
29 Mai 2007 von Alexander Kornbrust.
Mary Ann Davidson gave one of their famous talks on the AusCERT 2007. (”Every Marine fights… which means they know how to defend themselves”).
According to Mary Ann Davidson (Oracle CSO), applications will have to defend themselves from attack in the future.
How can a software defend from attacks? Every Marine has a weapon (M16) so probably attacking attackers is the best approach. This means we need also weapons for the database… After 3 invalid login attempts Oracle could ban the IP or start a denial of service (d.o.s.) attack against the bad ip address/address range. This could be a nice talk for one of the next security conferences.
I think this is the wrong approach. I agree with Mary Ann that developers (even Oracle developers) should develop good and secure code.

Oracle Security Riddle
28 Mai 2007 von Alexander Kornbrust.
During Oracle security audits we find from time to time the following (unsecure) code. Do you see the vulnerability and do you know how to exploit it?
Solution coming soon…
———-Code without exception handling—
FUNCTION CHGPWD (
P_USER VARCHAR2,
P_PWD VARCHAR2)
RETURN BOOLEAN IS
L_STMT VARCHAR2(255);
BEGIN
L_STMT:= ‘ALTER USER “‘ || P_USER || ‘” IDENTIFIED BY “‘ || P_PWD||’”‘;
EXECUTE IMMEDIATE L_STMT;
RETURN TRUE;
END;
