Some level of programming or scripting ability is required. For example, they should be able to port a tool form on flavor of Unix to another 
3.  Script kiddie – Script kiddie is a non-expert who breaks into computer systems by using pre-packaged automated tools written by others, usually with little understanding of the underlying concept—hence the term script (i.e. a prearranged plan or set of activities) kiddie (i.e. kid, child—an individual lacking knowledge and experience, immature)
