Rad je nastao kao uvod u detaljnije istraživanje solinskoga razvijenoga i kasnoga srednjeg vijeka. Radi se o svojevrsnom uvodom tekstu koji će se u budućnosti dodatno razraditi kako bi se dobila što cjelovitija slika topografije i povijesti ovoga prostora u navedenom razdoblju., The Classical and early medieval history of Solin play an immense role in the contexts of the national and the European histories alike. This paper is a collection of notes on the time that followed the most famous part of the Solin's history, making a base for further and more detailed researches. So far, this period has been best treated in the numerous works of Rev. Lovre Katić on the medieval and Early Modern Period history of Solin. The paper is intended to make a triptych. The first part, published in this issue of Tusculum, is to describe briefly time, space, borders and communications. The second part will be dedicated to the objects that existed alongside the communications and within the borders – churches, cemeteries, settlements, fortifications. The third part would be dedicated to the people of that time and the attitudes for the Classical town's ruins. Strictly speaking, in the period of time dealt with here there was no clearly delineated area of Solin, because its main character was being fought for by both Klis and Split. Same as in the previous, Classical, period, through the Solin area passed extremely important communications, connecting this area with its closer and farther hinterlands, but also with the neighbouring area of Trogir. Besides these, there are also less important, local communications, still waiting to be properly valued.

V diplomskem delu so predstavljeni protokoli za sledenje stikov. Protokoli so razdeljeni v dve glavni skupini, to so centralizirani in decentralizirani protokoli. Za vse protokole je opisano kako delujejo, izpostavljene so pa tudi njihove ranljivosti. Predstavljen je tudi koncept anonimnosti na internetu, njen pomen za uporabnike ter prednosti in slabosti visoke stopnje anonimnosti. Nato je predstavljen način ocenjevanja stopenj anonimnost, za vse predstavljene protokole pa je izdelana ocena nivoja anonimnosti, ki jo zagotavljajo. Poleg tega je predstavljena naša subjektivna metriko in protokoli so ovrednoteni glede na stopnjo zaupanja, ki ga naj bi vzbudili pri povprečnem uporabniku. The diploma thesis presents protocols for tracking contacts. The protocols are divided into two main groups, namely centralized and decentralized protocols. For all protocols, how they work is described, and their vulnerabilities are highlighted. The concept of anonymity on the Internet, its importance for users and the advantages and disadvantages of a high level of anonymity are also presented. Then, the method of assessing the levels of anonymity is presented, and for all the presented protocols, an assessment of the level of anonymity is provided. In addition, our subjective metric is presented, according to which individual protocols are evaluated according to the level of expected trust they should evoke in the average user.

Ovaj rad temelji se na istraživanju izvorne građe, rezultata arheoloških istraživanja te relevantne literature. Dotiče se pitanja važnosti rimskih puteva i komunikacija, pravnom ustroju i razdiobi istih. Rimljani su težili iskorištavanju prirodne topografije u svrhu širenja komunikacija unutar Carstva te u tome vidimo značajnost područja sjeverne Hrvatske gdje se rimske ceste protežu uz rijeke Savu, Dravu i Dunav. U ovome radu raspravlja se o prometnim komunikacijama u provinciji Panoniji, te se pozornost posvećuje putnim postajama - mansiones, uzduž bitnih rimskih puteva ovog područja i identifikaciji njihova slijeda s naglaskom na literarne izvore u kasnoantičkim itinerarima. This paper is based on research into source material, archaeological knowledge and relevant literature. Concerning the importance of Roman roads and communications, the legal structuration and distribution of the same, Romans sought to exploit the natural topography for the purpose of expanding communications within the Empire, and in this we see the importance of northern Croatia where the Roman roads extend along the rivers Sava, Drava and Danube. This paper discusses road communications in the province of Pannonia, and focuses on road stops - mansiones, along the important Roman roads of the area, and identifying their sequence with emphasis on literary sources in late antique itineraries.

V delu je predstavljena zgradba pametnega ventila, njihove značilnosti, način upravljanja ventila s strani uporabnika ter način komunikacije pametnega ventila z zunanjim svetom. Pri opisu posameznih enot se posebej osredotočamo na vhodne enote (senzorje) in procesno enoto. Večji poudarek je storjen tudi na samodejnem krmiljenju, saj je ena izmed pomembnejših značilnosti pametnih ventilov. Komunikacija ventila z zunanjim svetom poteka preko brezžičnih omrežij ali pa preko številnih novejših komunikacijskih protokolov. Ti omogočajo prenos podatkov v realnem času. Več različnih možnosti komunikacije, možnost obdelave podatkov, vsebovanje mnogih senzorjev ter zmožnost natančnega nadzorovanja samega sebe so tudi glavne razlike in hkrati prednosti pametnih ventilov pred običajnimi. In the thesis we present the structure of smart valves, their characteristics, the way the valve is operated by the user and the way the smart valve communicates with the outside world. When describing individual units, we pay special attention to the input units (sensors) and the process unit. The latter is the reason why we call the presented valves "smart". A major emphasis is given to automatic control which is one of the most distinguished characteristics of smart valves. Smart valves communicate via the numerous communication protocols in real time, data can be also transmitted via wireless networks. Various communication possibilities, data management, numerous sensors and precise automated control are one of the main advantages of smart vales against the classic ones.

Dolina na Savi jest naselje i groblje datirano u mlađu fazu kasnoga brončanog doba i prijelaz u starije željezno doba na kojem su u višegodišnjim istraživanjima otkriveni tragovi višestoljetnoga komuniciranja zajednica uz rijeku Savu i preko nje. Dolina na Savi nalazi se preko puta vrlo važnoga lokaliteta Donja Dolina u sjevernoj Bosni. Strateške točke u prostoru, poput Doline, i tragovi života u njima, otvaraju pitanja o korištenju krajolika, mijeni komunikacijskih pravaca i prednostima te nedostacima života uz rijeku Savu s naglaskom na mlađa razdoblja prapovijesti. Podaci prikupljeni arheološkim istraživanjima bacaju drugačije svjetlo na ulogu rijeke Save u komunikacijskoj mreži u južnom dijelu Karpatske kotline od slike kakvu imamo danas i kroz novovjekovnu povijest. Baština komunikacija manje je vidljiva, ali je izuzetno važna u proučavanju krajolika, upotrebi krajolika i tumačenju prošlosti. Okrenutost Požeške kotline savskoj dolini i prirodne komunikacije dolinom Orljave i klancima između slavonskih planina utjecale su na snažnu povezanost Zlatne doline s dolinom Save i uključenost u širu regionalnu komunikacijsku mrežu. Bolje poznavanje i razumijevanje lokalnih komunikacijskih baština pridonosi i širem regionalnom znanju te sagledavanju povijesnih zbivanja, osobito u važnom i dinamičnom komunikacijskom prostoru kakvo je međuriječje Drave i Save., Dolina na Savi is a settlement and a cemetery dated in the younger phase of the Late Bronze Age and the transition to the Early Iron Age. Traces of communication between communities along and across the river Sava through the centuries were discovered during septennial excavation. Dolina na Savi is situated across a very important site – Donja Dolina in northern Bosnia. Strategic points in a landscape such as Dolina and traces of life thereon open the questions about use of landscape, change of communication routes, and advantages and disadvantages of life along the river Sava, with the focus on the younger periods of prehistory. The data collected by archaeological research have shed a different light on the role of the river Sava in the communication network in the southern Carpathian Basin, in comparison with the picture of the role thereof present in modern history and currently. The heritage of communication is less visible, but exceptionally important in the research of landscape, the use of landscape, and the interpretation of the past. The orientation of the Požega Valley to the Sava Valley and natural communications by the Orljava Valley and clumps between Slavonian hills influenced strong connections of the Golden Valley with the Sava Valley, and involvement in a wider regional communication network. Better knowledge and understanding of local communication heritage have contributed to the bettering of wider regional knowledge and overview of historical events, especially in an important and dynamic communication area such as the interfluves of Drava and Sava.

Ovaj diplomski rad bavi se tematikom pronalaženja grešaka i izguljenih poruka u mreži zasnovanoj na CAN komunikacijskom protokolu. U sklopu zadatka rada kreiran je novi algoritam za filtriranje, klasifikaciju podatkovnog prometa i detekciju pogrešaka i izgubljenih poruka koji obrađuje .asc log i scenarij usmjeravanja poruka u mreži zasnovanoj na CAN protokolu. Kreirano vlastito rješenje u sebi analizira 16 vrsta usmjeravanja u mreži sa 4 čvora. Algoritam služi za otkrivanje izgubljenih poruka i poruka s neispravnim podatkovnim blokom. Kao rezultat algoritma dobije se izvještaj u obliku .xlsx datoteke kako bi se moglo proučiti na kojim kanalima se stvaraju najveću problemi i koje poruke se najviše gube. Na temelju tog izvještaja moguće je analizirati komunikaciju i poduzeti korake prema poboljšanju komunikacije. Algoritam je kreiran u Python skriptom jeziku u PyCharm razvojnom okruženju. Kreirani algoritam ima značajke modularnosti i nadogradivosti jer je kreiran u dijelovima koji mogu biti izmijenjeni neovisno o drugim modulima. Verifikacija je provedena unutar programskog rješenja tako da su se kreirali slučajevi unošenjem anomalija u .asc (ručno promijenjeni podaci) datoteku. Rezultati verifikacije su pozitivni i udovoljavaju zahtjevima postavljenim prije izrade samog rješenja. This thesis deals with the topic of fault finding and lost messages in a network based on CAN communication protocol. As part of the assignment, a new algorithm for filtering, classifying data traffic and detecting errors and lost messages has been created, that processes the .asc log and the message routing scenario in a network based on the CAN protocol. Created own solution analyzes 16 types of routing in a 4 node network. The algorithm serves to detect lost messages and messages with faulty data block. As a result of the algorithm, a report is given in form of .xlsx file so we could find out which channels are biggest problem and which messages are most losing ones. Based on this report, it is possible to analyze communication and take steps to improve communication. The algorithm is created in the Python script language in PyCharm development environment. The created algorithm has features of modularity and upgradability because it is created in parts that can be modified independently of other modules. Verification was carried out within the software solution so that cases were created by entering anomalies into the .asc (manually modified data) file. The results of the verification are positive and correspond to the set requirements before making the solution itself.

Krmilnik na vozičku krmili pogon vozička, da se voziček avtonomno pozicionira ter sledi hitrosti tekočega traku, na katerem so avtomobili. Prav tako pa javlja ter sprejema podatke iz centralnega krmilnega sistema. Za povezavo s polnilcem baterij je izvedena serijska komunikacija Modbus RTU. Za komunikacijo s čitalcem bar kode je izvedena serijska komunikacija po protokolu RS232. Za povezavo med krmilnikom vozička ter centralnim krmilnikom pa skrbi povezava preko protokola Profinet. Za natančno pozicijo vozička skrbi čitalec bar kode, iz katerega se nato izračunava tudi trenutna hitrost vozička. Za regulacijo hitrosti skrbi regulator hitrosti. Strojna oprema je sestavljena iz industrijskega programirljivega logičnega krmilnika, serijskih komunikacijskih modulov, polnilca akumulatorjev, čitalca bar kode ter opreme potrebne za zagotovitev nemotene žične ter brezžične povezave Profinet. Strojno opremo v celoto povezuje programska koda. Med programiranjem je bil vedno cilj napisati kodo kar se le da preprosto ter pri tem upoštevati vse segmente za varno obratovanje vozičkov. Pri tem pa seveda ohraniti preprostost upravljanja celotnega sistema. The diploma thesis deals with the construction, programming and control of 19 autonomous trolleys intended for charging car batteries. The system combines two different types of controllers that communicate via wireless network, the first being a control system and the second being 19 controllers, each mounted on its own trolley. The trolley controller controls the trolley drive autonomously, and follows the speed of the conveyor belt on which the cars are located. It also reports and receives data from the central control system. Modbus RTU communication is performed to connect to the battery charger, serial communication according to RS232 protocol is performed to communicate with the bar code reader. The connection between the trolley controller and the central controller is provided by the connection via the Profinet protocol. The exact position of the trolley is determined and assured by the bar code reader, from which the current speed of the cart is then calculated. Speed controller is responsible for speed control The hardware consists of an industrial programmable logic controller, serial communication modules, a battery charger, a bar code reader, and the equipment needed to ensure a smooth wired and wireless Profinet connection. Of course, the hardware is linked by software code. During programming, the goal was always to write the code as simply as possible, taking into account all segments for safe operation of the carts. In doing so, maintaining the simplicity of entire system management was of special importance.

V diplomski nalogi sem zgradil avtomatsko testno okolje, ki je namenjeno testiranju komunikacijskih terminalnih naprav na oddelku verifikacije v podjetju Iskratel. Naloga okolja je avtomatsko vzpostavljanje velikega števila zvez med dvema terminalnima napravama in odkrivanje morebitnih napak, ki se pojavijo po daljšem obratovanju terminala. Okolje je zgrajeno tako, da skuša čim bolj natančno simulirati uporabnika terminala. V ta namen se za avtomatsko klicanje uporablja robotska roka. Po njeni prvotni nastavitvi lahko ta neprestano ponavlja vzpostavljanje zvez med terminaloma. Ali je bila zveza uspešna, testno okolje preveri s preizkusom slišnosti, poleg tega pa meri tudi zakasnitev prenesenega zvoka. Okolje lahko z dodatno nastavitvijo parametrov meri tudi zaostajanje prenesene slike pri video zvezah in njeno odvisnost od zvoka. Končni rezultati nam tako omogočajo vpogled v dolgotrajno delovanje terminala ter zaznavo napak, ki jih je z ročnim testiranjem skoraj nemogoče odkriti. In my diploma work I made an automatic measuring environment, which is designed for testing communication terminals in the verification stage of production. It is designed to establish multiple connections between two communication terminals to find possible errors, that might appear during long operation. Goal of the environment is to simulate a terminal user as best as possible. To establish the connection between two terminals a robotic arm is used. After its first initialization the robot can constantly place calls between terminals. Successful connection is then tested with audibility test. Besides that, environment also calculates delay of the transferred sound or image in case of video calls. Final results allow users to analyze long-term terminal operation and detect errors, which would be impossible to find with manual testing.

Množični mediji so ena od najpomembnejših institucij sodobne družbe. Njihova vloga pri oblikovanju, delovanju in evoluciji družbene zavesti je ogromna.V diplomskem delu smo predstavili vlogo množičnih medijev v Rusiji, zgodovino njihovega razvoja ter preučili kako jih urejajo, predvsem pravno. Nato smo naredili primerjalno analizo pravne ureditve medijev v Rusiji in v Evropske Uniji, za predstavnico katere smo izbrali Nemčijo. Na koncu smo opredelili učinkovitost obstoječega sistema pravne ureditve in podali glavne smeri razvoja za njegovo izboljšanje. Mass media are one of the most important institutions of modern society. Their role in the formation, functioning and evolution of social consciousness is enormous. The thesis presents the role of mass media in Russia, the history of their development and how they are regulated, mainly by the law. Furthermore, it contains a comparative analysis of media regulation in Russia and the European Union, represented by Germany. In the end, we defined the effectiveness of the existing system of regulation and presented the main direction of development for its improvement.

Svjetski pomorski sustav za pogibelj i sigurnost (engl. Global Maritime Distress and Safety System – GMDSS) značajno je unaprijedio sigurnost navigacije i omogućio pomorcima dobivanje informacija koje su važne za sigurnost plovidbe.

V diplomski nalogi smo sestavili okviren pregled kart slovenskega ozemlja 18. in 19. stoletja. Na obravnavanih kartah smo analizirali prikaz izbranih kartografskih elementov in njihovo generalizacijo. Pri tem smo se osredotočili na prikaz oblikovanosti površja, naselij in grajenih objektov, komunikacij in vodovja. Sestavili smo preglednice uporabljenih postopkov kartografske generalizacije na posameznih kartah. Prav tako smo opravili kratek opis generalizacije v sodobnem času in jo primerjali z generalizacijo v obravnavanem obdobju. In the thesis, we have compiled a brief overview of the maps of Slovenian territory in 18th and 19th century. We have analysed the chosen cartographic elements and their generalisation. Our focus has been depiction of surface, towns and buildings, communication infrastructure and waters. We have compiled the charts of all procedures used in cartographic generalisation on each map. Additionally we have prepared a description of the cartographic generalisation in modern era and conducted a comparison with cartographic generalisation in 18th and 19th century.

This article explores the relationship between communication, with the emphasis on public relations, and social network perspectives. What, then, does social networking for business mean in communication, particularly in public relations? This paper argues that business social networking play an important role in improving organizations communications. The goal of our paper is to identify the basic characteristics of social networks and its role for public relations for the effective implementation of social networking initiatives and tools in the workplace. Business social networking tools such as Facebook and LinkedIn are being used by organizations to reach the corporate objectives and to create a positive company image. Specific social networks, such the personalised networks of influence, are perceived to be one of the main strategic resources for organizations.

Over the past few years we have been witnessing a rapid development of communication technology. The aim of this article is to find a technical solution for increasing the existent optical cable capacities. The purpose is not to replace the existing cables but to use advanced technology and to improve the economy, safety and reliability of all kinds of communications that use an optical transmission medium. Komunikacije so v zadnjih letih dosegle nesluten razvoj, tako v sociološkem kot tehničnem pogledu. Danes hoče praktično vsak komunicirati z vsakim ob vsakem času. Vsi se trudijo, da pri tern ne bi bilo ovir. Generator teh sprememb je v največji meri industrija, ki skrbi za razvoj komunikacij. Uporabniki pa se hitrim in pogostim spremembam v veliki večini izogibajo. Ko zadostijo osnovne komunikacijske potrebe, jih le stežka prepričamo v kaj novega. Od tu dalje pa tehnika ne igra več najpomembnejše vloge. Na vrsti je marketing, trgovanje, ponudbe in obljube. Članek obravnava problematiko povečanja kapacitet že izgrajene optične infrastrukture in to z uporabo inovativnih tehničnih rešitev. Uporabno vrednost tega lahko apliciramo povsod tam, kjer so kapacitete za prenos informacij že zasedene, uporabniki pa potrebujejo vedno nove storitve. Prednosti takšnega pristopa niso le ekonomske, temveč povečujejo obstoječe kapacitete, izboljšujejo varnost in zanesljivost vseh vrst komunikacij, kjer uporabljamo optične prenosne medije.

V delu definiramo internet stvari kot skupino infrastruktur, ki omogočajo dostop, upravljanje in rudarjenje na podatkih, ki jih generirajo glede na okolico in interakcijo z uporabniki. Infrastrukture sestavljajo stvari, posredniki, podatkovne storitve, programski vmesniki, spletne in druge storitve, skupaj pa omogočajo prenos obdelavo in dostop podatkov s senzorjev ter nadzor aktuatorjev in spreminjanje notranjega stanja stvari. Stvari so naprave z določeno funkcijo, s senzorji za zaznavanje okolice in aktuatorji za manipulacijo okolice ter s sposobnostjo komunikacije z drugimi stvarmi, prehodi ali z drugimi omrežji. Opremljeni z definicijo interneta stvari identificiramo nabor lastnosti, ki opisujejo aplikacije IoT in določimo gradnike, ki sestavljajo aplikacije IoT: stvari, posredniki ali prehodi ali stičišča, podatkovne shrambe in različne storitve. Določimo še osnovne arhitekture v katerih se lahko pojavljajo gradniki IoT. S tako določeno taksonomijo in pojmom aplikacije IoT zgradimo sistem za modeliranje aplikacij IoT, ki na podlagi zahtev aplikacije določi najprimernejšo arhitekturo in platformo, ki ju lahko izberemo za implementacijo aplikacije. S tem zmanjšamo prag za vstop v razvoj aplikacij IoT. Orodje za modeliranje aplikacij IoT uporabimo za izdelavo pametne kuhinjske posode, ki se zaveda svoje teže in lahko posveti z diodo LED, v odvisnosti od notranjega stanja posode. Kot dokaz delovanja pripravimo vse komponente aplikacije IoT. Izdelamo tudi nadzorne in podporne spletne storitve, s katerimi se dotaknemo dogodkovno vodenega programiranja, komunikacije preko protokola WebSocket in težav s komunikacijami preko tehnologije Bluetooth LE. V zaključku nakažemo možnost širitve taksonomije in skupnosti okrog koncepta testiranja modelov (angl. model unit testing). Nakažemo tudi možnost samodejnega odkrivanja lastnosti in priporočil s pomočjo strojnega učenja. We define the internet of things as a group of infrastructures for accessing, mining and management of data that is generated by the environment or by users. Infrastructures are comprised of things, transport elements, data services, programming interfaces, web services and other services. Infrastructures enable sensor data access, actuator control, and internal state change. Things are devices with a specific function and might have one or more sensors to sense the environment and zero or more actuators to act in the environment. Things can communicate with other things, gateways and other networks. This definition of IoT allows us to identify a base set of attributes that can be used to describe IoT applications and basic components that appear in an IoT application such as things, gateways or hubs, data storages and services. We define the basic system architectures that are used in IoT applications. We build an IoT application model based on this taxonomy. The model takes a list of properties representing application requirements and proposes the best architecture and platform to use for building the desired IoT application. This reduces the friction to enter the world of IoT development. We use the model to recommend the platform and an architecture for a smart kitchen container application. The smart kitchen container is aware of its weight and has an LED light that can be controlled through the network or through the internal state. As a proof of concept we implement the IoT application including all the cloud based support services. In conclusion we show a possible future direction of work developing a model unit testing tools. We also make suggestions for automatic feature learning and classification with machine learning.

Kot srednje veliko podjetje iz Slovenije smo se v bližnji preteklosti pridružili globalnemu podjetju, ki sega na vse celine sveta. Posledično se je struktura lokalnega IT povezala v strukturo globalnega IT, ki je za sabo potegnila precejšnje prilagoditve in spremembe. Ker postajamo številčno vse večji, se posledično pojavlja težava, kako vso to masovno infrastrukturo nadzorovati. V takih razmerah nam sodobna informacijska tehnologija lahko hitro postane konkurenčna prednost, saj bi brez nje težko obvladovali potrebe svojih strank. Diplomsko delo obravnava predstavitev in implementacijo Landesk produkta na lokalnem nivoju, konfiguracijo in uporabo modula Landesk za distribucijo in nadgradnjo programske opreme in operacijskih sistemov na lokalnem, kot tudi na globalnem nivoju podjetja Poclain Hydraulics.

As a medium-sized company from Slovenia we have become a part of global company from 2007 which is presented in all continents of the world. The structure of the local IT department is now connected into global IT structure, consequently, we are pushed into large adjustments and changes. Since our infrastructure become bigger and bigger, we encountered the problem, how to control and manage efficiently all those massive global infrastructure. In such circumstances, a modern information technology can quickly become a competitive advantage, because without it, it is hard to cope with the needs of its customers. Thesis shows the presentation and implementation of LANDesk product at the local level, configuration and useage of the Distribution module of LANDesk and upgrading of software and operating systems on a local level, as well as at the global level of company Poclain Hydraulics. It is presented the past and the current situation on local level, installing and updating of local software and patches, explanation of the objectives and needs, presentation of implementation, modules presentation, followed by conclusions of proposed solutions and results.

Ovaj rad opisuje kako moderna ICT tehnologija pridonosi razvoju moderne vatrogasne službe. Kroz rad su opisane različite aplikacije, prvenstveno za pametne telefone i tablete koje se koriste te aplikacije koje su razvijene u Hrvatskoj ili se mogu pronaći na elektroničkim servisima za distribuciju aplikacija (AppStore, PlayMarket itd.). Aplikacije se koriste kako bi vatrogascima pružile pravovremene informacije ili pomogle kod obavljanja vatrogasne djelatnosti. Korist od različitih aplikacija i sustava imaju svi u vatrogasnoj hijerarhiji, od vatrogasca, zapovjednika/voditelja pojedine intervencije pa do zapovjednika postrojbi, županijskih zapovjednika itd. Aplikacije koje se mogu pronaći ili se razvijaju, namijenjene su za različite nivoe u vatrogasnim postrojbama i organizacijama. Svaka modernizacija ili bilo kakva pomoć pri obavljaju vatrogasnih intervencija pridonosi osnovnom zadatku vatrogasnih postrojbi, a to je što prije i učinkovitije pomoći građanima u različitim nevoljama. Kako se vatrogasna djelatnost obavlja većinom na terenu, tada su od velike pomoći različite mobilne aplikacije i servisi koji pružaju različite informacije, a i međusobnu komunikaciju vatrogascima na terenu., This paper describes how modern ICT technology contributes the development of modern fire service. Through the work described different applications, primarily for smartphones and tablets that are used and the applications that were developed in Croatia or can be found on the electronic services for distribution applications (AppStore, PlayMarket etc.). applications are used to provide timely firefighters information or help with performing firefighting activities. The benefits of different applications and systems have all the fire hierarchy, from firefighter, commander / leader individual interventions to the unit commanders, county commander, etc. Applications that can be found or developed, are intended for different levels in the fire fighting units and organizations. Any modernization or any help perform firefighting intervention contributes to the mission of the fire brigades, and that is as soon as possible and effective assistance to citizens in their various needs. As the fire activity is carried out mostly on the ground, then were of great help various mobile applications and services that provide a variety of information, and communicate with each other firefighters on the ground.

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.
