Abstract

Network security is defined as “a set of procedures, practices and technologies for protecting network servers, network users and their surrounding organizations” (Oppliger, 2000, Preface). The need for network security is caused by the introduction of distributed systems, networks, and facilities for data communication. Improved network security is required because of the rapid development of communication networks. Network security is achieved by using software based tools, that is, network security software (Pulkkis, Grahn & Åström, 2003).
