What would be the solution to this? If I’m a leader in a company with a culture and intangibles not yet optimized for the people working in the infosec roles, how would I aproach changing the environment for the better? Is it viable to cooperate with other companies to share best practices? Wouldn’t they hesitate to share? Would doing deep interviews with potential employees get me the right information? Would some hr consultancy provide this info? Arent’t they too old-fashioned for this field yet?
