Network and Computer Security Project - Medical Records

Health care institutions gather and store sensitive information from patients with the goal of providing the best care possible. The medical history of a patient is essential to allow correct diagnostic and help the clinical staff act in the shortest time possible. This information is highly sensitive and must be kept private for the responsible staff only. At the same time, the medical records should be accessible by any health care institution to ensure that a patient can be assisted anywhere.

To guarantee data availability, health care institutions in the future might rely on data repositories accessible through the Internet. This poses a threat, since patient data can be accessed by unauthorized personnel. It is also extremely difficult to manage access to data using standard access control mechanisms due to the vast amounts of user, groups and patients and the constant adjustment in privileges that must be done to maintain patient’s confidentiality.

In this topic we define a cloud-based system to store medical records. The records are available for a wide range of users, so the system provides a web interface to manage access privileges to the records. We use Atribute Based Access Control (ABAC) and the standard architecture XACML was implemented using AuthzForce. More information can be found in the report under /docs.

You must have installed the following tools:

• Maven 3.x.x
• Java Development Kit 8 (JDK 8)
• MariaDB 10.x
• Java Keytool (you must have a command alias for Java Keytool "keytool") in order to generate keys.

Also check if JAVA_HOME and M2_HOME are set properly.

• By default the port 8080 accepts HTTP requests and redirects them to port 8443 as HTTPS requests (This only work with GET)

• You can change the ports in /medical-records/server/src/main/resources/application.properties changing the

properties server.http.port and server.port respectively.

• Rename the file /medical-records/server/src/main/resources/database.properties.example to database.properties and fill it with your database credentials. According to your OS follow the next instructions to setup the encryption of MariaDB.

• Copy the files medical-records/server/src/main/resources/keys.enc and medical-records/src/main/resources/.key to mysql config folder (usually /etc/mysql/, where config file is located)

• Comment lines 2, 8, 9, 10, 11, 12 of medical-records/server/src/main/resources/dbconfig-linux, and check if the file paths for the keys are correct.

• Copy dbconfig-linux file contents to mysql config file (usually /etc/mysql/my.cnf)

• Restart mariadb service

• Access mariadb and insert the following statement:

	INSTALL PLUGIN file_key_management SONAME 'file_key_management.so';

• Uncomment the lines previously commented (2, 8, 9, 10, 11, 12)

• Remove the .key file from the config folder and it's good to go

• Everytime the mariadb service starts, the key must be in the the config folder

• Copy the files medical-records/server/src/main/resources/keys.enc and medical-records/server/src/main/resources/.key to mysql config folder (usually /usr/local/var/mysql/, where config file is located)

• Comment lines 2, 8, 9, 10, 11, 12 of medical-records/src/main/resources/dbconfig-macos, and check if the file paths for the keys are correct.

• Copy dbconfig-macos file contents to mysql config file (usually /usr/local/etc/my.cnf)

• Restart mariadb service

• Access mariadb and insert the following statement:

	INSTALL PLUGIN file_key_management SONAME 'file_key_management.so';

• Uncomment the lines previously commented (2, 8, 9, 10, 11, 12)

• Remove the .key file from the config folder and it's good to go

• Everytime the mariadb service starts, the key must be in the the config folder

• Copy the files /medical-records/server/src/main/resources/keys.enc and medical-records/server/src/main/resources/.key to mysql config folder (usually C:\Program Files\MariaDB X.X\data\, where config file is located)

• Copy dbconfig-windows file contents to mysql config file (usually C:\Program Files\MariaDB X.X\data\my.ini)

• Restart mariadb service

• Everytime the mariadb service starts, the key must be in the the config folder

The first time you want to run the project you need to run the following command in /medical-records/:

mvn clean install

If there are tests failing, something is not well configured. Check section Debugging.

Run the following command in the directory /medical-records/server/

mvn clean spring-boot:run -Dspring-boot.run.arguments="1099"  -Dserver.port="8081"

mvn clean spring-boot:run -Dspring-boot.run.arguments="1098"  -Dserver.port="8082"

Run the following command in the directory /medical-records/front-end/

mvn clean spring-boot:run

Create a file named jaxp.properties (if it doesn't exist) under /<path to jdk1.8.0>/jre/lib and then write this line in it:

javax.xml.accessExternalSchema = all
