| Abstract [eng] |
When rapidly increases advantages of digital technology, also increases impact of network security in the industry. With the development of protocols, increase trensfer throughput, creating a new data transmittion technology, allowing unauthorized visitors online visits, which may cause unexpected losses for the company. For this reason, we need to prevent burglary before it takes place. With the development of methods of attack, we are forced to improve safeguard tools. This paper will examine the security systems and their application areas, using sourses collected, also created a versatile industry network security system that separates the LAN (Local Access Network) – the company network from the unsafe network, which is the main source of the attacks. Universal network security system consists of conventional intrusion detection, intrusion prevention and firewall security system. In addition, an overview of the internal LAN security systems designed to prevent the intrusion of internal origin. Joint network security system consists of conventional intrusion detection, intrusion prevention and firewall security system. Made network analysis reports by DoS (Denial of Service) attacks criteria also detected pps (packets per second) bandwidth increase by 1879% and 3729% (in different assessment methods) investigation of Internet data traffic, while visiting potentially harmful content sites. Based on this test, Matlab Simulink environment carried out in the usual firewall and security system, which includes a firewall, intrusion detection and prevention system, whose main advantage is the possibility of real-time supplement hacking database research. This system is suitably against the attacks of sources detected by examining the message header. |
