A computer attack may originate from an error or carelessness of an employee in the use of technology. Train your users in the fundamentals of computer security to achieve a responsible use of their information and the technologies with which they interact daily.
Create a security culture in your IT staff as network administrators, DBAs and analysts to develop the awareness and technical skills necessary to integrate security into your organization.
A large part of the computer attacks are initiated in the application layer due to vulnerabilities introduced in the software. Train your architects, developers, testers / QAs and Managers to develop the awareness and technical skills necessary to integrate security at every stage of development.
