A FORENSIC LOGGING SYSTEM BASED ON A SECURE OS
Ilkyeun Ra, Tae-Kyou Park · International journal of computer science and applications · 2009
This paper describes a forensic logging system that collects fine-grained trace evidence from target servers and networks. To provide a more reliable and efficient forensic logging system, we developed a dedicated network processor that collects network traffic and a hardened TCSEC-B1 level secure operating system. The system also is capable of defending servers from malicious attacks as well as allowing system security managers to obtain forensic evidence from the forensic logging system when the target system is assaulted by malicious attacks from the internet. We present the structure of the system and discuss the benchmark test results of our prototype system.
