Abstract
V diplomski nalogi je predstavljena storitev Tehnično nadzorni center kot dopolnilo oziroma nadgradnja napredne vzdrževalne pogodbe sistemov tehničnega varovanja, ki jih v podjetju Iskra d. d. vzdržujemo. Sistemi tehničnega varovanja vključujejo sisteme požarnega varovanja, protivlomnega varovanja, zaznavanja plina, sisteme gašenja, sisteme kontrole pristopa, videonadzora in registracije delovnega časa. Predstavljeni so tudi glavni gradniki, prenosne poti in zagotavljanje varnosti komunikacij. Glavni del diplomske naloge zajema operativni sprejem, obdelavo in posredovanje tehničnih alarmov. V prvem delu diplomske naloge so opisani posamezni gradniki strojne opreme tehnično nadzornega centra. Pod glavne gradnike spadajo sprejemniki alarmnih sporočil, ki za komunikacijo uporabljajo različne prenosne poti, vmesniki za oddajanje alarmnih sporočil, vmesniki za posredovanje kratkih sporočil, mrežna oprema za zagotavljanje varnosti komunikacij, telefonska centrala, strežniki ter naprave za zagotavljanje brezprekinitvenega napajanja. Opisane so poglavitne značilnosti in napredne funkcije, ki jih posamezni gradniki omogočajo. V nadaljevanju je opisano zagotavljanje varnosti komunikacij na strani naročnika, med prenosom na komunikacijski poti in na strani tehnično nadzornega centra. Opisani so različni varnostni mehanizmi in tehnološke rešitve, zakaj so potrebne in kje so uporabljene ter možnosti zlorabe, vdora in odtujitve bodisi osebnih podatkov, zaupnih dokumentov ali opreme. Predstavljene so osnove kriptografije, uporaba simetričnih, asimetričnih ključev, uporaba javnih in privatnih certifikatov ter varnostna politika, pa tudi programske in strojne rešitve. V glavnem delu diplomske naloge je opisan operativni sprejem tehničnega alarma, pretvorba signala v primerno in uporabniku prijazno obliko, dodajanje naročnikov v sistem, konfiguracija in opis naprednih avtomatskih funkcij za posameznega naročnika. Opisani so različni načini delovanja, ustvarjanja poročil ter avtomatsko posredovanje sporočila odgovornim osebam, ki imajo ob sprejemu signala nalogo takojšnjega odziva in preverjanja stanja sistema tehničnega varovanja na daljavo ter, v kolikor je to mogoče, odpravo napake na daljavo ali pomoč naročniku na daljavo.

Title:Control center for remote management of technical security systems
Abstract:
This thesis deals with the demonstration of Technical Control Center as an added upgrade of the advance maintenance contract in technical security area that I work in. Technical security systems represents Fire Alarm Systems, Intrusion Alarm Systems, Video Surveillance Systems, Gas Detection and Aspiration Systems, Access Control Systems, Conference Systems and Public Address Voice Alarm Systems. In thesis I also present main components of information transport solutions and transport paths as well as ensuring the security of communications. The main part covers how the operator receives, handles and forwards technical alarms. The first chapter describes several hardware communication modules, communicators, interfaces of Technical Control Center, such as communications receiver/gateway that communicates via different transport paths, modules for sending technical alarm messages, short messages (SMS), network equipment that provides secure communication, private branch exchange system, servers and devices for uninterruptable power supply. I describe main features and advanced functionalities that each of these components enable. Further on I describe maintaining secure communication on the customers site, on the transmission path and on the Technical Control Center side. There are a lot of different security mechanisms and technological solutions. Some of them are presented here. Why and where do we need them? How to exploit, gain access or worse steal/intercept valuable data? Basic cryptography, symmetric/asymmetric keys, public/private certificates, security policy and software/hardware solutions are also being discussed. The main part of the thesis discusses the user friendly operation of receiving/handling/forwarding technical alarms, converting signals in a proper form, adding new customers in the system, configuring of advanced automation functions for each customer separately. There are different types of operation suited for every single situation. In case of technical alarm we can either manually or automatically create and send various reports to main individuals on the customer site or the Technical Control Center site. Each individual has its own process flow, response time, jobs and where possible diagnosing and/or solving the malfunction. In other situations also remote support is possible and expected.

Keywords:technical alarms from fire/intrusion/video/access… systems, control center, communications receiver, secure communications, handling technical alarms, remote support.
