It is only considered secure enough , until it is broken by someone smarter or with more power and money to coerce.
Of course I am excluding private information that someone takes to their grave.
A one time use password is best until THE "comodo hacker" hacks and downloads the decrypted server.
HDD's with encryption hardware is better than software, until someone spies on the laptop accessing the server or uses leverage to find the information another way.
Just as 1 in a million medical doctors might have the experience necessary to save a life that no on else could on a consistent basis.
Imagine a Doctor who had all the critical skills of experience from every faculty of medicine.
I am trying to draw a parallel that the best Security guru is similar to a MASH doctor with a broad range of skills.
Saving a life is the utmost rewarding job anyone can have, when one has the experience. My old brother-in-law was like this, on 3 open heart teams in different hospitals, professor of Anesthesia and Sr. Intensive Care Specialist, but he would only say he puts people to sleep and uses Chicken soup. Yet every day saved lives in critical jeopardy. He would take me to a hockey game and I would recognize no one in the seats while during intermission, every few minutes another stranger would come up to shake his hand ( another life saved)
Even Bruce Schneirer says " Security is real hard" , but not impossible to design the best bang for the buck or find the weakest links in security with a broad deep experience base in many industries that is essential to acquire these talents with analytical acumen.
