Šio darbo tikslas buvo sukurti reikalavimais grindžiamą duomenų saugumo ir matomumo metodų pasirinkimo bei jų kombinavimo metodinę medžiagą. Pateikti reikalavimas grindžiamą kompleksinės saugos modelį. Pašalinti kompleksinės apsaugos metodų informacijos trūkumą. Darbe išnagrinėti ir palyginti garsių pasaulio saugos specialistų kompleksinės saugos sprendimai. Atlikta sistemos pažeidimų analizė ir sisteminimas. Darbe buvo siekiama atskleisti svarbiausius pažeidimus, jų veikimo principus ir kaip nuo jų tinkamai apsisaugoti. Praktinėje dalyje aprašytas kompleksinis saugos modelis, kuris vėliau smulkinamas į detalius apsaugos modelius. Modelis buvo pritaikytas šiandien populiariausiose kombinuotoje sistemose Microsoft Windows Server 2008 serveryje ir Microsoft SQL Server 2008 duomenų bazių valdymo sistemoje. Naudojantis metodika galima atlikti esamos sistemos saugumo analizę ir remiantis veiklos modeliais teisingai konfigūruoti esamą ar naujai kuriamą sistemą. / This work destination was to create requirements based on data security and availability method choosing and their combination methodology. Introduce requirements based on complex security model. Eliminate information lack of complex security. In work analyzed and compared complex security solutions of famous the word security specialists. Accomplished system vulnerability analysis and systematized information. During the work revealed most important vulnerabilities, explain how it works and how correctly secure of them. In this research described security model of complex security, which later detailed as smaller part of model. Complex security model were used at nowadays most popular combined information system. For research were used Microsoft Windows Server 2008 and Microsoft SQL Server 2008. Created methodology is useful then necessary to test existing or creating new configuration of system.
