Network security issues

Increasingly, distributed processing is used to achieve the availability and processing power required by today's information technology systems. Networks are an important element in this drive towards more responsive systems. These systems can vary in size from a few desk top machines connected together in a single office to a complex of mainframes, controllers and terminals owned by a variety of organizations worldwide. It is shown that much work has been done to establish the security services that can be provided to users of these networks. If these services are to achieve their desired level of service, however, careful attention must be paid to the way they are planned, implemented and, in particular, the way in which they are managed.     

浅析我国网络安全存在问题及解决对策

我们平常所说的网络安全包括人、技术、地区、法规、社会舆论及教育管制等许多因素。随着社会的迅速发展,网络安全问题越来越受到人们的重视,同时,网络中出现的各种安全性问题需要我们关注并及时解决。本文主要就目前我国存在的网络安全问题及其解决对策进行了探讨和分析。     

我国企业管理信息化建设的探究

企业信息化管理指的就是企业将自身生产过程中的业务流程、生产过程、客户交换、事物处理等工作进行电子化和数字化的处理,并且应用先进的信息系统网络加工组合数据信息,进而得到新的信息资源,提供给企业各个部门的人员参考和使用,最终设计出最好的解决方案,对企业的资源进行充分的利用。也就是促使企业更好的适应和顺应市场的发展,最大化企业的利益。文章主要分析和研究了我国企业的信息化建设,并对信息化建设中的问题进行了分析,最后提出了解决的对策,为我国企业管理的信息化建设提供了一定的参考依据。     

An informational theory of security

This presentation of a systems theory is applicable to security in the private sector which is profit dependent. At a time of heightened security specialization, it is necessary to establish a professional consensus that all private security areas are unified at the basic conceptual level. Business and industry face numerous threats to profitability. Threats applicable to the mission of security have been organized here by the WAECUP (waste, accident, error, crime, unethical practice) acronym. WAECUP threats are shown to be so interrelated that a security department that ignores even one threat is bound to fail. Computer security and all private sector security are shown linked in efforts to make loss control (the author's term for modern security) effective. The most common fallacy about private security is to equate it with police activity. This myth is dismantled and security is defined by a careful comparison between law enforcement and private security with respect to their clients, goals, focus, environmental restructuring abilities, and movement (access) controls. A graphic Loss Control Model is offered to explain how informational transfer minimizes loss and tends to stabilize any corporation. It is an open-ended systems model that all private security practitioners can identify with and utilize as a heuristic tool.     

基于计算机网络建设中的安全性问题分析

近几年来,随着信息技术的不断发展,计算机在各个生产及生活领域均得到了广泛应用。在给人们生活、工作带来方便的同时,也带来了信息安全问题,使得信息在网络中破坏及泄露,为此,加强计算机网络的安全建设具有重要意义。本文首先分析计算机网络建设中的安全性问题,然后重点分析其安全对策。     

Estimating the informational security level of a typical corporate network

For the general logical and probabilistic models of estimating the success of an attack on a defense object in a typical corporate network, we have obtained and found extreme values of the corresponding analytic expressions for the weights and sensitivity functions in various factors (defense functions). On the example of a typical corporate functions, by using the sensitivity functions formalism, we have obtained risk estimated for certain dangerous events and practical recommendations to increase the level of information security.     

Network security

Security in computer networks is often viewed as too expensive, but it is important. A first step in protecting a computer network is to restrict access. A product has been designed to provide secure identification of a user for access to a network, computer and data system. A system has also been developed which handles user verification, message protection and message privacy. This system is application-dependent.     

Re-examining the security issues of ATM systems

The automated teller machine (ATM) system is the well-known system in E-society that provides us with easy access to banking activities, e.g. money transfers between a user's accounts. This article focuses on the security issues of ATM systems. We examine a criminal case concerning large-scale fraudulent cash withdrawals at ATMs around Taiwan. The common tricks used by criminals are copies of cards as well as the use of tiny cameras to record the personal identification numbers of card users. With continued advances in technology, the criminal case can be handled easily. We also discuss security policies to prevent fraudulent cash withdrawals.
