In this study security is defined rather broadly. It comprises the traditional forms of security expressed in occupations like armed forces, police officers and security guards. But it includes also more general security occupations like lawyers and judges and the corresponding educational programmes; occupations and programmes which contribute to ‘security’ at a more institutional level. Also, a large number of ICT-occupations and educational programmes are classified as related to security. More and more elements of these occupations and educational programmes are dedicated to security to guarantee the integrity of ICT-systems and protect against cybercrime and fraud. And finally, occupations and programmes in the field of social work are included in the security domain.
