In P2P systems, it is important to guarantee the efficiency and security of message routing between the source and the destination. Unfortunately, malicious attackers can easily insert a lot of nodes they controlled, and disturb the message routing between honest nodes. In order to counter such attacks, secure routing protocols which ensure successful message routing are needed. Furthermore, it is...
In this paper we compare four risk analysis methods: Mehari, Magerit, NIST800-30 and Microsoft's Security Management Guide. Mehari is a method for risk analysis and risk management developed by CLUSIF (Club de la Securite del' Information Francais). Magerit is a risk analysis and management methodology for information systems developed by CSAE (Consejo Superior de Administracion Electronica). NIST800-30...
Intrusions are one of the most important issues in the current Internet environment. Therefore, a lot of researchers and companies elaborated countermeasure techniques such as intrusion detection systems (IDS) and intrusion prevention systems (IPS). These systems detect intrusions and prevent attackers from succeeding in their intrusion attempts. They usually rely on pattern matching and therefore,...
Nowadays, security policy evaluation becomes a very hot topic since high QoP(quality of protection) is required by more and more people. Most of the researchers focus on the security policy evaluation after they have been enforced into real application systems via some real attacks. However, before security policy enforcement, the policy themselves may also contain some anomalies which shouldn't be...
For leveraging the security level of the systems, it is required to develop an effective and practical methodology for evaluating the adequacy of the designed and/or implemented security counter- measures for a system. We propose a model as a one of the methodologies for evaluating security countermeasures which does not depend on the characteristics of a target system shown by the supporting businesses...
Digital forensics encompasses the process of identifying the perpetrator and the criminal method by analyzing the logs generated in the computer. Log files record the activities of the computer and by reading them one can know what kind of event happened at a certain time. Therefore, secure logs with the integrity property are essential. In this paper, we discuss two approaches to achieve the integrity...
We have developed content protection technologies best suitable for hard disk drives. Besides large capacity and high speed, the hard disk drive has some better features than optical discs, one of which is intelligent enough to make bi-directional authentication to the system. This benefit realizes more flexible and reliable protection of digital content. This paper describes the total framework of...
We previously developed standards for a new type of removable storage device called an "information versatile disk for removable usage" (iVDRtrade1) as members of the iVDR hard disk drive consortium. The standards cover both the physical and application aspects, but not cover content protection. We have now developed architecture to protect the content recorded on the removable storage device...
