Abstract:	With the facilities that an image archiving system offers, the HUB Hospital Universitário de Brasília (Brasilia University Hospital) decided to implement a PACS server that allowed it to receive and store images using the DICOM protocol. This, in turn, allowed it to view images and make medical diagnoses using a Web interface. As a solution to this problem, a PACS server suggested by INCOR-SP named miniWebPACS was used. In August 2007, the author of this dissertation was invited by his Thesis Orientation Professor to evaluate the security of the miniWebPACS application at use at the HUB. After evaluating the source code of this application, security failures were found. The first failure permitted an illmeaning invader to, through network traffic capture tools, identify the parameters through which the DICOM protocol authenticates, thus permitting illicit medical images to be sent in the name of a licit networked piece of medical equipment. The second failure is the possibility of reassembling the medical image by capturing all the network packets transmitted between the medical equipment and the server, therefore destroying the patients informations confidentiality. The security failures were extremely serious, and, if exploited, could damage the HUBs and its doctors images. The simple substitution of the miniWebPACS server for another, more secure, server was not viable, given that the HUB had already developed several solutions for manipulating medical data using the current server. Thus, the hub2pacs project was born with the objective of developing a PACS server for the transmission of medical images in a more secure manner, using as a reference the dcm4che free development software library, and preserving the data model at use at the HUB. The Hub2pacs solved, for once and for all, not only the compatibility issues with the old applications that had already been developed, but also offered a guarantee of confidentiality in the communications channel and the authentication of all the parts involved. However, an environmental analysis pointed out the necessity of allowing medical equipment without support for DICOM/TLS to transfer images securely too. To solve this problem a new project was started called hub2conversor.
