MOBILE SECURITY
Introduction ? Mobile devices, such as smart phones and tablets, typically need to support multiple security objectives: 1)Confidentiality 2)Integrity 3)availability
Targets for attackers ? Data ? Identity ? Availability Attacks Based on wi-fi Based on network Based on sms,mms Based on vulnarabilities in software.
Sources to insecure phone ? Worms: A worm is a program that reproduces on multiple computers across a network. ? Malware: A malware is a computer program that aims to harm the system in which it resides. ?
