Izbor antivirusnog softvera za zaštitu radnih stanica

Abstract

S obzirom na značaj zaštite informacionih sistema u savremenom poslovanju, u okviru ovog primera bavićemo se izborom antivirusnog softvera za zaštitu radnih stanica. Poznato je da nijedan softver ne pruža kompletnu zaštitu, pa je zato zadatak menadžmenta da odabere onaj koji na najbolji mogući način zadovoljava postavljene kriterijume. Samo jedan deo celokupne zaštite informacionih sistema preduzeća predstavlja zaštita radnih stanica na kojima zaposleni svakodnevno obavljaju svoje radne zadatke. Zaštita radnih stanica podrazumeva instalaciju antivirusnog sistema zaštite. Zbog toga je pre donošenja odluke o izboru antivirusnog softvera neophodno sprovesti testiranja antivirusnih softverskih rešenja, a menadžment preduzeća može da nakon dobijanja rezultata tih testova lakše donese odgovorajuću odluku primena Sistema za podršku odlučivanju (SPO). U konkretnom slučaju to je softver Criterium Decision Plus 3.0.4/S. Dobra antivirusna zaštita treba da zadovolji odgovarajuće kriterijume odnosno pokaže dobre rezultate prilikom testiranja. Neophodno je da se često obnavlja baza virusa, što automatski poveća mogućnost detektovanja potencijalnih pretnji. Takone neophodno je da ima sposobnost da fajlove, na kojima su detektovani virusi ili maliciozni kodovi, dezinfikuje. Poželjno je da antivirusni softver ima mogućnost brzog skeniranja računara, s obzirom da je skeniranje neophodno svakodnevno, a da pritom zauzetost memorije i zagušenje procesora nisu veliki. U konkretnom slučaju, sagledavanjem rezultata testiranja i detaljne analize rezultata dobijenih primenom navedenog softvera, odlučeno je da se antivirusni softver Nod32 prihvati kao trenutno najbolje rešenje i da se izvrši negova primena u preduzeću.

According to significance of information systems protection in modern business, this paper describes method of choosing antivirus software for workstations. Although, complete protection cannot be achieved using of one of existing antivirus software, managers should choose solution which in given criteria could give adequate support. Problem of workstation protection represents just one part of information system protection policy in an enterprise. Workstation protection implies installation of antivirus protection system. Before making decision of implementation adequate antivirus protection system, it is necessary to perform testing several antivirus package. We use decision support system for multicriteria decision in testing performance of several antivirus protection systems. CDP is used by public institutions and managers for support in consensus and structuring decision making process in situations where lot of criteria, alternatives and users are involved. It combines power of system analysis, easy of use and good graphic interface. Also, CDP enables decisions analysis and it is very useful for consultants to explain clients process of judgment in making decision or advice. Designed decision making model for choosing antivirus software for workstations protection enables multicriteria optimization of results which are attained by antiviral software testing. Good antivirus protection system, should satisfy given set of criteria, primarily. Further, it is necessary to permanently update virus database, which give to it potential for detecting potential threats. Also, it is necessary that chosen antivirus protection system has ability for disinfection detected viruses and threatening codes. Speed of system scanning, memory used, processor slow down are also criteria which we use in evaluation of antivirus protection systems. In case of testing antivirus software for this particular enterprise, results by applying decision support systems indicate that Nod32 represents best solution for implementation.
