3.6 At the highest level, the knowledge and skills that are needed by those tasked with investigating electronic attacks on critical national infrastructure and other targets, as well as those dealing with the analysis and interpretation of electronic evidence, irrespective of the crime type, are far greater than those engaged in more traditional law enforcement related work. Here a clear plan will need to be developed to meet the varying needs of each individual. The numbers of people requiring this high level training will vary from country to country, and in some smaller countries may even be in single figures. Where the number of trainees does not support a national approach, it may be necessary to look at options, such as regional training, since there is no less a requirement for staff to be adequately trained just because they are few in number. A structured approach has to be developed in order to identify these issues in each country. 3.7 An example of the levels within such a structure is given in the following chart which principally relates to the law enforcement community; however the principle that the higher the knowledge level required, the lower the number of staff that need to be trained can equally be applied to all actors in the criminal justice system. 41
