Cloud security technologies

You may have heard a new term that started making rounds very recently – “cloud-based security”. In this paper we describe past and contemporary security technologies based on the knowledge provided from the servers in the Internet “cloud”. We discuss how cloud-based malware scanners can simbiotically coexist with traditional scanning technologies, what are the advantages and limitations of the new approach. We also touch on the privacy aspects and challenges related to testing (especially comparative testing) of the cloud security solutions.
