Network security - precondition of implementation of the e-commerce

E-commerce is becoming a precondition and a form of commerce in the modern settings of organized business systems. Therefore it is necessary to realize the level of security that can be achieved through implementation of various methods. One of the basic areas of security is safe communication between spatially remote subjects that work for the common goal. Along with the security, defined as a need to realize consistency of the communication and to keep the integrity of the message, there also exists the demand for protection from non-authorized use of the content in exchange. The authors provide a review of required methods and procedures, whose application for realization of the required level of network security represents necessary foundation for applicative superstructure, i.e. for realization of e-commerce. Although seemingly at the lowest level of system functioning, network security depends upon several factors. For some time already, a group of factors is being taken into consideration, for example: applied protocols, message encryption, firewalls, physical separation of services on physically removed servers, doubled hardware, manifold and alternative connections with Internet, etc. Authors provide approach to definition and application of measures of network security levels, which in turn have to envelop applicative layer ; some of them envelop the choice and basic principles of operational system, or require definition, implementation, control, regular verification and modification of security policy.
