Abstract
The article presents a few aspects of the knowledge sharing process, both through conventional means and through those provided by information and communication technology. The first part includes a brief outline regarding knowledge sharing through communities of practice, emphasizing only those that conduct their activity in the online environment, followed by a short description of sharing platforms. Another element approached is an IT app of a demonstrative model of a knowledge bank for the domain of Defense, Public Order and National Security, resulting from my doctoral research. This is accompanied by a pilot study proving the manner in which the usefulness of this bank is perceived with the help of an on-line questionnaire. The research presented is destined to raising awareness in the field of knowledge banks and has the role to formulate conclusions which are going to allow increasing the efficiency in the development of similar platforms.
