Detecting anomalous communications through header-based application fingerprinting

Passive application fingerprinting is a technique to detect anomalous outgoing connections. By monitoring the network traffic, a security monitor passively learns the network characteristics of the applications installed on each machine, and uses them to detect the presence of ...

We investigate the problem of detecting advanced covert channel techniques, namely victim-aware adaptive covert channels. An adaptive covert channel is considered victim-aware when the attacker mimics the content of its victim’s legitimate communication, such as application-la ...

DEteCtion of Anomalous outbouNd HTTP Traffic by Passive Application Fingerprinting

We present DECANTeR, a system to detect anomalous outbound HTTP communication, which passively extracts fingerprints for each application running on a monitored host. The goal of our system is to detect unknown malware and backdoor communication indicated by unknown fingerprin ...

We address the problem of determining what data has been leaked from a system after its recovery from a successful attack. This is a forensic process which is relevant to give a better understanding of the impact of a data breach, but more importantly it is becoming mandatory acc ...
