Security is a shield (environment) we create around us to feel secure from things we dont want to be affected.
Security always has its scope, it can be personal , it can be family, society, National , or global.. for example terrorism is a national security threat, global warming is a threat with the scope of global. the point is we in real life underestimate security where things are under our control and overestimate security where things are not in our control. let me put it this way, how come riding on a bike on a highway can be more secure than having a terrorist attack? in both the cases chances are equally high that you will die, but we care less about bike because we think we have things in our control, and overestimate terrorism because that’s not in our control.
Its very common that people often misunderstood information security as a technical security, think about this which firewall restricts an employee to share his password to his friend? can you secure that ? the answer is NO.
