Abstract
Recent evolution of mobile technologies has opened new use possibilities
for mobile devices. At the same time information security problems related to
mobile devices have gotten more serious. More and more files e.g. pictures,
music, games and office documents are loaded from the Internet to mobile
devices. The purpose of this study is to investigate a possibility of remotely
and securely transferring these files between the mobile device and home
computer. Different security protocols are analysed and compared for mobile
device use in wireless environments with a literary research. The focus on
this study is also on information security threats related to mobile device
use such as eavesdropping on the wireless communication, software
vulnerabilities and stealing the device itself. The research problem is: how
to maintain sufficient information security with remote file transfers between
mobile device and personal computer? The research problem has been approached
with a literary research and a constructive study. A web based file server is
constructed and configured using open source software components and special
attention is paid to information security. The information security of the
construction is evaluated with STRIDE threat analysis, which lists threats
concerned with different parts of the system. Also, the file server has been
tested with security testing tools for completing the threat analysis. Based
on the threat analysis and security testing, the construction is considered to
be secure when properly used. However, new software vulnerabilities are
discovered daily. Therefore, the information security of the setup weakens if
not updated frequently. Also user made changes to configuration files, poor
management of login information and careless use of devices are problems cause
information security threats. The presented construction can be considered
useful feature for mobile device user, if he or she understands the
information security threats related to device use even at high level.
