What kind of degree are you looking to study in Israel? Are you interested in M.Sc (graduate) degrees? or B.Sc. (undergraduate) degrees? As far as I know, the only M.Sc. track open to international students is in Ben Gurion University of the Negev, in Beer Sheba. This track is studied in English. It is designed to be completed in 2 years and is suitable for those with a high GPA in computer science, software engineering or information systems B.Sc. degrees. As for B.Sc. degrees - unfortunately there are currently no such programs, but you can find international B.Sc. tracks in computer science, where you will most likely be able to learn about aspects of cyber security as well. These programs take place at - IDC Herzliya.
Please let us know if you have any questions or would like to receive more information about any specific track.
