20.500.12556/DKUM-37435 IMPLEMENTACIJA POŽARNE PREGRADE V PODJETJU UNISTAR LC D.O.O. IMPLEMENTATION OF FIREWALL IN UNISTAR LC D.O.O.COMPANY Požarna pregrada je osnovna komponenta za zagotavljanje informacijske varnosti v organizacijah. Izbiri ustrezne požarne pregrade in njeni pravilni implementaciji moramo posvetiti veliko pozornost. V prvem, teoretičnem delu diplomske naloge, smo opisali osnove računalniških komunikacij in protokolov. Poleg tega smo podali osnovne funkcionalnosti modernih požarnih pregrad. V drugem, praktičnem delu diplomske naloge, smo pozornost posvetili izbiri ustrezne požarne pregrade za podjetje Unistar LC d.o.o. Pozornost smo namenili postopku definicije tehničnih zahtev, katerim mora nova požarna pregrada ustrezati. Na osnovi zahtevanih tehničnih lastnosti smo izbrali štiri požarne pregrade različnih proizvajalcev. Med štirimi požarnimi pregradami smo izvedli primerjavo glede na zmogljivost, varnostno učinkovitost in ceno. Na osnovi rezultatov primerjave, smo izbrali požarno pregrado Check Point DS 4207 kot najustreznejšo za podjetje Unistar LC d.o.o. V zadnjem delu je prikazan postopek implementacije izbrane požarne pregrade Check Point DS 4207. Prikazani postopki vsebujejo nastavitve IP naslovov na posamezni požarni pregradi, postavitev gruče, baze dostopnih pravil, preslikave IP naslovov, sistema za preprečevanje vdorov, preverjanje identitete in nastavitev navideznih privatnih omrežij. Na koncu sledi analiza učinkovitosti, s katero preverjamo ustreznost nastavitev požarne pregrade. Končni rezultat diplomske naloge je visoko razpoložljiva in zanesljiva požarna pregrada, ki bistveno prispeva k višjem nivoju informacijske varnosti v podjetju Unistar LC d.o.o. Firewall is the main device, used for network security assurance in organisations. Choosing the appropriate firewall and its correct implementation is an essential task. In the first, theoretical part of the diploma thesis, the basis of network communications and protocols are explained. Besides, a review of the most important functionalities of modern or next generation firewalls is given. In the second, practical part, we focus on selection of an appropriate firewall for the company Unistar LC d.o.o. The required technical characteristic that new firewall must meet were defined. Among many firewalls available in the market, four most suitable solutions were chosen. Between all four models the performance, security effectiveness and price comparison was carried out. On the basis of comparison results the Check Point DS 4207 firewall was selected to be the most appropriate firewall for the company Unistar LC d.o.o. In the last part of the diploma thesis, the implementation process of the Check Point DS 4207 firewall is described in detail. The implementation process includes IP addresses setting, firewall clustering, rule base definition, network address translation, intrusion prevention system activation, identity awareness and virtual private networking. At the end, an example of network traffic analysis, which is used to check the firewall settings, is also shown. The final result of the diploma thesis is a highly available and reliable firewall which contributes essentially to higher level of security of Unistar LC d.o.o computer network. informacijski sistem komunikacije požarna pregrada komunikacijska varnost preprečevanje vdorov information system communications firewall communications security intrusion prevention true true false Slovenski jezik Angleški jezik Diplomsko delo 2012-08-30 21:59:00 2013-01-24 09:34:27 2022-04-23 23:08:52 2021-04-17 03:23:37 2012 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 7121171 URN:SI:UM:DK:HA8QVXNE VS_Kralj_Stefan_2012.pdf VS_Kralj_Stefan_2012.pdf 1 EE80390FDA345E0E3EB523409BA3832E c81e54f22c6fe6a5549294f2a06ca2d84888830728fc8d7b4cab9f2ccb1571f9 35d109b5-7c08-11eb-bb7a-00155d0001ca 20.500.12556/dkum/4991061e-2f96-4979-b8ac-50ad3af84823 https://dk.um.si/Dokument.php?lang=slv&id=49507 Fakulteta za organizacijske vede 0 0 0
