Creating covert channels in Linux-based cloud container environments

El propósito de los sistemas es poder entender de manera práctica las diferencias que existen en utilizar un sistema sin ningún nivel de seguridad (InsecureSystem) en comparación con otro sistema con un nivel de seguridad simple (SecureSystem). También mostrar que pueden existir vulnerabilidades en los sistemas seguros. Para esto se realizará un canal encubierto para transmitir un mensaje desde un sujeto con un nivel de autorización superior a otro sujeto con un nivel de autorización inferior (SecureSystemWithCovertChannel).
