Abstract
Maģistra darbā ir izpētīti un salīdzināti populārāki autorizācijas modeļi. Izmantojot iegūtās zināšanas tiek analizētas valsts nozīmes portāla viss.gov.lv RBAC bāzēta autorizācijas modeļa vājās puses un piedāvāti uzlabojumi. Tiek piedāvāts autorizācijas modelis, kuru var izmantot veidojot jaunu sistēmu, vai uzlabojot eksistējošo. Modelis balstās uz ABAC autorizācijas modeli, kas ietver sevī arī RBAC modeļa īpašības. Modelis izmanto XACML valodu, lietotāju tiesību pārvaldībai, kas atvieglo sistēmas izstrādātāju un administratoru darbību. Darbā tiek aprakstīts izveidota modeļa prototips kopā ar tā izmantošanas piemēru, kas ļauj pārliecināties, ka modelis ir praktiski pielietojams izvirzītu prasību izpildei.
