Title: A changing nature of warfare requires a change of mindset of defense intelligence and the role of OSINT and social networks therein

There is a radical change underway in which warfare is being conducted. That change is there, it has been there for quit some time and it will most probably continue to grow in importance and significance. It is called Computer Network Operations (CNO), or, information warfare or cyber warfare. Two forms are of particular interest: computer network attack (CNA: attacking, changing and possibly destroying systems of the opposing forces) and computer network exploitation (CNE: cyber espionage, or finding and taking sensitive information from computer networks). For every threat there are in reality two threats, the second one being the vulberability to attack by its victims, due to lack of awareness, training and education. Social networks play a crucial role in CNO especially for the deployment of cyber weapons such as identity theft and the disseminiation of malware to create computer zombie networks. Two traditional intelligence collection disciplines need to change their mindset: SIGINT and OSINT as the logical foundation of CNO. The keynote speech will address these issues and explain the important relationship between social networks
