As Certified Ethical hacker and Penetration Testing Always people Asked me about if the Oracle Password can be Cracked or not ? You need to know that if the hacker want to get into your database and he will all you can do is make it harder for him , so don’t choose Easy password to crack
I post these topics not to use it in wrong way , No as DBA you need to know about Securing you database
and How to make it unbreakable.
For example check the below tools that used to crack Oracle Password
And Others Tools Found for free On Internet , for example Red database security (which is amazing company and website provide you with article/topics about oracle security ) provide some of these tools for free.
Thank you
