In the wake of the fast popularization of information and the rise of electronic commerce, information security is gaining much attention. How to perform the evaluation of the value of assets, how to perform the analysis of the risks associated with assets, and how to protect information assets from sabotage, theft and tamper are important topics in the study of the management of information security. We address the aspects of confidentiality, integrity and availability of information and apply the Analytic Hierarchy Process (AHP) to consolidate expert's opinions on information risks, in order to construct an integrated framework for risk analysis. The BS7799 standard and the risk level matrix (RLM) are used accordingly to evaluate the effectiveness of and to categorize the risk management measures and to create a complete model for the assessment of information assets related risks. Finally, the research results are verified by a case study. The results can be used by organizations as references for information security planning and management process improvements.

A remote user authentication scheme is a procedure for a server to authenticate a remote user in a network. Recently, Lee et al. proposed a fingerprint-based remote user authentication scheme to overcome the security flaw in Hwang and Li's scheme. In Lee et al.'s authentication scheme, they store two secret keys and some public elements in a smart card. We first review Lee et al.'s fingerprint-based user authentication scheme. Next, we show that Lee et al.'s scheme still suffers from the impersonation attack.

Packet dropping attack (PDA) is a network attack that utilizes compromised network elements to degrade network performance or quality by intentionally dropping a certain amount of IP packets. The major distinction of the PDA from traditional denial-of service (DoS) attack is that some victims do not even discern that they are under attack. Offensive router detection (ORD) is a mechanism capable of detecting offensive routers that are performing the PDA. The ORD mechanism is based on the principle of conservation of flow in the network, and employs a new proposed ICMP message, Caddie message, which records packet forwarding information in the Caddie messages. Therefore, after analyzing the information, we can identify routers that are abnormally dropping packets. We show the advantages of the ORD mechanism over other existing network monitoring mechanisms and discusses storage and bandwidth overhead issues. We also demonstrate the advantages and the effectiveness of the approach by simulating the functionality of the ORD mechanism to detect four different packet-dropping patterns.
丢包攻击(Packet drop attack, PDA)是一种利用受损的网元，故意丢弃一定数量的IP报文，从而降低网络性能或质量的网络攻击。PDA与传统的拒绝服务(DoS)攻击的主要区别在于，一些受害者甚至没有意识到他们正在受到攻击。攻击性路由器检测(ORD)是一种能够检测正在执行PDA的攻击性路由器的机制。ORD机制基于网络中流量守恒的原则，采用了一种新提出的ICMP报文——Caddie报文，在Caddie报文中记录报文的转发信息。因此，通过分析这些信息，我们可以识别出异常丢包的路由器。我们展示了ORD机制相对于其他现有网络监控机制的优势，并讨论了存储和带宽开销问题。我们还通过模拟ORD机制的功能来检测四种不同的数据包丢弃模式，从而证明了该方法的优点和有效性。

We present an efficient scheme for mobile devices to conduct transactions demanding high security. The use of cryptographic mechanisms is minimized by applying block-ciphers and one-way hash primitives, which can be operated with low-end processors and very little working space. Undeniable billing can be achieved by applying one-way hash chains. Owing to one-way hash functions, the integrity of the masked transactions and the billing information can be verified, even when the masked information is transmitted in public. Complicated cryptographic mechanisms, also the regulations among roaming countries, thus can be eliminated so that a light-weight billing can be achieved.

Content-based audio feature extraction is key to obtaining important message from audio information. Research in the past several years has focused on the use of speech recognition techniques that are not directly applicable to compressed audio bit stream. However, subband coding based MPEG-1 audio layer III (MP3) is now useful for any system with limited channel capacity for its high quality to bit rate ratio. It has been widely adopted in audio-on-demand, music link via ISDN and digital satellite broadcasting. Message collection is easier if audio content can be extract directly on subband domain. Several useful algorithms are proposed here to manifest this idea.

We propose a simple key agreement protocol(SKA) that provides key establishment with authentication over an insecure channel using only a human memorable password. The SKA is based on Diffie-Hellman scheme and has many of desirable security attributes: it resists off-line dictionary attacks mounted by either passive or active adversaries over network, allowing low-entropy passwords to be used safely. It also offers perfect forward secrecy, which protects past sessions and passwords against future compromise. Besides, it is secure against an adversary who captured a host's password file. Since user passwords are stored in a verifier form, the adversary cannot use it directly to compromise security. The proposed scheme here shows that it is more efficient in computational time and communication overhead over the existing schemes.

To achieve fully automatic surveillance of fires, an intelligent real-time fire detection method based on a 2-stage decision strategy of video processing is proposed. The first decision stage is to check if there is a existing fire by extracting fire-pixels from visual images. In color image processing, the RGB (red, green, blue) color model has less computational complexity than other color models and hence is adopted to describe fire pixels. The decision function of fire-pixels can be deduced by the saturation of R component and fire's dynamic features. In the second decision stage, if the number of extracted fire pixels is increasing with burning time and greater than someone threshold during a time interval, a fire alarm is given to avoid leading to a disaster. To reduce false-alarm rate, the second decision process is repeated with several times at an adaptive thresholding way. Experimental results demonstrate that the proposed method is very attractive for the important military, social security, forest-fire alarm, commercial applications, and so on.

Web servers are increasingly being adopted as a viable means to access Internet-based applications. Current solutions to secure Web servers are not comprehensive or robust enough to protect servers and applications from today's hackers. Protection profile gives us a systematic approach to examine the minimum-security requirements of a system. Therefore, we derive the Web security components that make a secure Web serve from the Web Server Protection Profile. A component-based framework as well as an open source solution is given subsequently. We believe that after the system is implemented and deployed, it functions reliably and effectively. We aim at establishing the provable reliability of construction and the feasibility of component-based solutions for the secure Web server.

The announcement made by The Executive Yuan at September 10, 2002 about Chinese hacker invasion and implanting the Trojan program and collecting information from November 2001 to July 2002 disclosed once more the fact that our national information security mechanism is still insufficient. Based on this fact, we firstly take a simple insight of the present situation of hacker invasion and communication monitoring system, and discuss the penetration testing instructions made by Premier Yu, and then, referring to the implementation by western countries of building up "Information Sharing and Analysis Centers" (ISAC) to deal with information security threats such as the "Chinese hacker invasion" event, we will expound the issue. Moreover, we are also studying the necessary steps of the planning and implementation of the defensive mechanism for Information and Communication security, which is crucial to our National Information and Communicative Initiative (NICI).

The terrorist attack is one type of emergency caused by humans. This emergency is rare, but can cause catastrophic effects. In the aftermath of 9-11, it is proprietary security personnel's responsibility to help every employee get back to "business as normal" while at the same time, being prepared for possible terrorist attacks. An up-to-date contingency plan is expected to help security managers to fulfill this role. Security managers should reassess or develop the contingency plan by using the Federal Emergency Management Agency's (FEMA) guidebook. They are encouraged to adopt the Homeland Security Advisory System, or alternatively to develop a simple color-coded system, to response the threats of terrorist attack in stages. They are suggested to consider three factors-top executive's commitment, adequate trainings, and coordination with public agencies-in the planning.
