Quantitative Metrics and Measurement Methodologies for System Security Assurance
Proactive approaches for preventing attacks through security measurements are crucial for preventing sophisticated attacks. However, proactive measures must employ qualitative security metrics and systemic measurement methodologies to assess security guarantees, as some metrics (e.g., entropy) used …

A Comparison of Static to Biologically Modeled Intrusion Detection Systems
… evolving threats combined with unique new attack vectors, maintaining signatures for every individual piece of malware becomes unwieldy. A biologically modeled intrusion detection system based on the behavior of a population of ants has many advantages over traditional security measures. …

Threat Detection in Program Execution and Data Movement: Theory and Practice
Program attacks are one of the oldest and fundamental cyber threats. They compromise the confidentiality of data, the integrity of program logic, and the availability of services. This threat becomes even severer when followed by other malicious activities such as data exfiltration. The integration …
