Abstract
La seguridad de los archivos del usuario ha sido, y es hoy en día, uno de los valores más vulnerados por parte del cibercrimen. Esto se debe a que cada vez, los ordenadores se han vuelto una herramienta más indispensable en la vida de las personas. Con ello, se han desarrollado paralelamente mecanismos para vulnerar las medidas de seguridad de estos equipos y acceder a información sensible dentro de los mismos. Por este motivo, el desarrollo de herramientas que sean capaces de brindar una protección sólida a archivos importantes para el usuario se ha convertido en una tarea de vital importancia.
Dentro de este contexto, DataSekura nace como una manera de proteger información almacenada tanto en el sistema local de archivos como en servicios Cloud mediante el uso de técnicas de cifrado. La aplicación permite al usuario seleccionar un directorio local o una carpeta en la nube y cifrarla con un nivel de seguridad de lo más exigente.
Cuando se habla de seguridad, más en concreto a la seguridad conseguida mediante técnicas criptográficas, se habla de tres pilares fundamentales:
• Confidencialidad: Evitar el acceso a la información por parte de terceros no autorizados, así como fugas de información.
• Integridad: Garantizar que la información no resulta modificada de forma no autorizada. Ç
• Disponibilidad: Garantizar que la información sea accesible por un tercero autorizado siempre que lo desee.
A la vez que se consigue el nivel de seguridad mencionado anteriormente, DataSekura también representa una forma de agilizar y hacer más cómodo para el usuario el uso de las tecnologías empleadas para la construcción del producto final.
The security of user files has been, and still is, one of the most relevant values compromised by cybercrime. This is a consequence of computers becoming a fundamental tool in people’s lives. In parallel, mechanisms to violate the security measures of these computers and access sensitive information within them have been created. For this reason, the development of tools that can provide a strong and solid protection to files which the user considers important has become a task of vital importance. Within this context, DataSekura was created to protect information stored both in the local file system and in Cloud services by using encryption techniques. The application allows the user to select a local directory or a directory in the Cloud and encrypt it with a very high level of security. When talking about security, more specifically the security achieved through cryptographic techniques, three pillars must be distinguished: • Confidentiality: The access to information by unauthorized third parties, as well as information leaks must be prevented. • Integrity: The information must not be modified in an unauthorized way. • Availability: An authorized third party will be able to access the information whenever he wants to. As well as achieving the level of security mentioned above, DataSekura speeds up and makes the usage of the external technologies used for the construction of the final product more comfortable for the user.
