The first two sets of videos are concerned with basic concepts. We begin, in the first video, by discussing the nature of security itself, and the difficulty of finding a satisfactory definition. In the second video, we look at problems of providing security, especially in daily life, what happens in its absence. In the third video, we look at conflict, the problems of defining what it is, and the many different reasons why it may happen.

The second set of videos concentrates more on issues related to the state. The fourth video is concerned with the provision of security by the state (and others) and how this has changed through history. The fifth video looks at security and development, discussing problems of the definition of development and the need for state-provided security if development is to happen, as well as security problems resulting from development itself. The sixth video looks at security and stability, discussing the problems of defining stability, and asking if we can ever say whether a state is « stable » or not.

The third set of videos is concerned with the security sector itself. The seventh video looks at the question of defining the security sector, to begin with. The eighth lecture discusses the various components of the security sector, and how they have grown up historically in different places. The ninth lecture is concerned with security policy, and trying to make the parts of the security sector work together according to a coherent plan.

The fourth set of videos is concerned with more general issues. The tenth lecture is about the language we use to describe security problems, and how it can be misleading and manipulative. The eleventh lecture provides some pointers to help to think about security problems, and the twelfth lecture looks at major security problems of the future.
