What is difference between Vulnerability & Limitation ??

From last few days I was in Security Seminar with few Industry TOP SHOTS. This was the biggest question discussed becoz most of the time some so called "BLACK HATS" create big "HOAX" on the name of VULNERABILITY.

For any attack to be successful, there should be a vulnerability which exists in the system. Generally the vulnerabilities that exist in the software such as Operating System and Applications can be removed by implementing proper patch management solutions.

But there exists an inherent vulnerability in all the systems which is called “Limitations” and that is the vulnerability that is being targeted by most of "BLACK HATS".

Every Technology has its own Limitation which can be exploited by any tech geek with advance level of knowledge. But instead of telling the truth, they claiming to be found some "ZERO DAY" and pretends to be a GREAT HACKER Blah blah blah blah....
