Network of Excellence – SENTER

SENTERDirektorat za notranje zadeve Evropske komisije je sprejel v financiranje aktivnosti delovanja in razvoja Mreže Centrov odličnosti na področju boja zoper kibernetsko kriminaliteto – SENTER (Strengthening European Network Centres of Excellence in Cybercrime). Mrežo sestavljajo priznane univerze in raziskovalni centri iz starih članic EU ter tri iz skupine novejših članic EU. Med njimi je Slovenija z Laboratorijem za odprte sisteme in mreže Instituta “Jožef Stefan”. Delovanje mreže je namenjeno raziskavam metod in tehnik za preprečevanje kibernetske kriminalitete in kibernetskega terorizma ter prenosu in izmenjavi znanja z deležniki iz civilne sfere, tožilcev in organov pregona. Posebna pozornost bo namenjena vzpostavitvi partnerstva in sodelovanja s podobnimi institucijami iz ZDA, Latinske Amerike, Afrike, Avstralije in Azije, saj kibernetski kriminal nima mej in deluje na svetovnih kibernetskih omrežjih.


An Authentication and Authorization Solution for a Multi-Platform Cloud Environment (MUPOSS)

Providing security at all levels within the multi-platform cloud-computing environment is still not considered to be properly solved due to a variety of problems arising from technical and human-based sources. We have developed authentication-and-authorization solution based on the Single Sign-On (SSO) approach for cloud-service users and administrators in a multi-platform environment. The system developed enables user authentication for clouds provided as Infrastructure as a Service system built up from different OS systems. The solution enables the use of different services based on credentials that are authenticated only once and enable simple and efficient administration of the relevant data.

MUPOSS solution was published by Cigoj, Primož, and Borka Jerman Blažič. “An Authentication and Authorization Solution for a Multiplatform Cloud Environment.” Information Security Journal: A Global Perspective 24.4-6 (2015): 146-156.
