People are often the most overlooked element in any security strategy. This is unfortunate, because no matter how solid the technology and the processes, if the people are not engaged, data breaches happen.
One of the more positive steps an enterprise can make is to institute ongoing security awareness training for all employees, whether it's a cashier or customer service rep. But don't just present the material and hope for the best. Follow any employee training with testing to gauge understanding and to reinforce the vital importance of security.
Among other data-driven security processes, an enterprise security policy must clearly state how people should respond to requests for sensitive information. This security policy should be enforced by technology controls, so employees can't be coerced into providing hackers with information, and also to reinforce the importance of security within the enterprise.
A strong culture of security will emphasize the fact that each employee is a valued participant in preventing data breaches, not a child who is being monitored. It takes time to build an internal corporate culture, and it takes reinforcement to drive home a security message, but to make progress on the security journey, we need to bring all employees in the company along with us.
