[Purpose] The paper aims to explore instructional design of the structure under the web-based environment, as well as the similarities and differences with the traditional instructional design; with its teaching resources,methods and students' ability to develop design strategies. [Method]Through the introduction of systems analysis and experimental control and from the network hardware environment, resources, environment and cultural environment the network learning environment design is brought forth. [Results]The results show that the network environment, information technology, instructional design, which are based on the learner and the teaching process for the study, aims to achieve a good learning environment, to organize the various elements; to form an ordered system; particularly to emphasis on learning characteristics and learning needs analysis of the measurement, to focus on the design of learning environments and “communication-oriented” classroom activities. [Conclusions] This instructional design under network information technology environment is a very important significance for a variety effective learning activities, for students to stimulate motivation to learn.

The topic of the individual learning conditions creation can be analysed from the technological as well as pedagogical side. In both cases there is the same fundamental point: how to create valuable and as much as possible natural learning environment? The experience in the application of technologies for personalisation, analysed in scientific literature, reveals newer possibilities for the individual activities support. This encourages taking a different route in analysing individual learning – to interdisciplinary combine the content of close concepts. The paper deals with basic concepts of interdisciplinary content analysis – informatics and information technology impact to an individual learning in primary school.

Even before September 11, 2001, security and privacy was a concern to nearly 80% of the current and potential Internet users around the globe, according to survey released by the Information Technology Association of America (ITAA) (Poulsen, 2000). The survey, commissioned by the American Express Company, randomly polled 11,410 people in 10 countries, and found that nearly half of the respondents enjoyed some form of Internet access. As might be expected, most of the world’s Internet users utilize Internet for e-mail, browsing, and entertainment. However, fewer than 28% do some shopping online, and 24% use the Internet for banking and financial transactions. But when Internet users and non-users of many countries were asked if they agree with the statement, “I am or would be concerned about security and privacy issues when purchasing or making financial transactions online,” 79% agreed. Prior to the tragedy of September 11, 2001, U.S. citizens also expressed legitimate concerns toward the issues of privacy and security, with an 85% showing. The poll released by the Information Technology Association of America also illustrated that approximately 80% have doubts about the U.S. government’s ability to maintain computer security and privacy. Hence, protecting operating systems is a major strategic concern if the success of e-government as a whole is to reach its potential. Although most of these issues are typically not discussed in relationship with e-government, the need for trusted computing systems within e-business and computing systems can be made as an effective argument that all these issues affect e-government systems as well. Secure computing systems issues in terms of e-government are just as important.  The scope of this article is to present a description of one the most generally known security certifications; namely, the trusted computer system evaluation (TCSEC) and its commercial implementation procedure in the commercial product evaluation process and discuss the influence of this evaluation/certification on the incidence of hacker attacks on e-business. As evident by the abundance of marketing literature of different operating systems for e-business that frequently refers to its security strength ranked against popular security certifications, it is very common to rank commercially available operating systems against TCSEC evaluation and/or certification criteria. This article will also explore where the many operating systems stands on this particular evaluation. In essence, given the vulnerabilities exposed after September 11, 2001, strategic security managers should be deeply concerned that the e-business platform they are responsible for contains the highest security standards to prevent any type of potentially harmful hacker attacks. Managers need to have a working knowledge of TCSEC security evaluation/certifications to become better informed when choosing the e-security platform for e-government/e-business. Essentially, the selection of a particular operating system for e-government/e-business have as much to do with factors ranging from existing skills, existing infrastructure, and economic reasons all the way up to political and strategic reasons. In dealing strategically with modern e-business environments, one of the most important factors that management must consider when choosing an operating system for their e-business platform is the security strength to resist computer hacker attacks on the operating system. If, for example, during different hacker attacks, one of the major aspects of these attacks is a certain operating system, as opposed to other systems, then this is a clear message to management to build in proper safeguards in the proposed operating system (Smith & Rupp, 2002a, 2002b). Certainly some of the reasons for frequent hacker attacks may probabilistic in terms and not random events, since Linux and Windows operating systems are more frequently used for e-commerce than other systems. So, it is not surprising that there are practically few reports of successful hacker attacks against operating systems that run e-business platforms (Smith, 2005; Smith & Lias, 2005; Smith & Offodile, 2002).

Today, information security is one of the highest priorities on the IT agenda. In 2003, Luftman and McLean (2004) conducted a survey of Society for Information Management members to identify the top 20 information technology (IT) issues for executives. Security and privacy issues were ranked third, after IT/ business alignment and IT strategic planning. Concept of information security applies to all the data stored in information systems or being communicated in information networks and encompasses measures applied on all layers of open system interconnect (OSI) model of international standards such as application, networking, and physical. Sophisticated technologies and methods have been developed to: • Control access to computer networks • Secure information systems with advanced cryptography and security models • Establish standards for operating systems with focus on confidentiality • Communication integrity and availability for securing different types of networks • Manage trustworthy networks and support business continuity planning, disaster recovery, and auditing The most widely recognized standards are: • In the United States: Trusted Computer System Evaluation Criteria (TCSEC). • In Canada: Canadian Trusted Computer Product Evaluation Criteria (CTCPEC). • In Europe: Information Technology Security Evaluation Criteria (ITSEC). All of theses standards have recently been aggregated into Common Criteria standards. And yet, the information systems continue to be penetrated internally and externally at a high rate by malicious code, attacks leading to loss of processing capability (like distributed denial-of-service attack), impersonation and session hijacking (like man-in-the-middle attack), sniffing, illegal data mining, spying, and others. The problem points to three areas: technology, law, and IT administration. Even prior to the drama of 9/11, several computer laws were enacted in the USA and yet more may come in the future. Still the fundamental threats to information security, whether they originated outside the network or by the company’s insiders, are based on fundamental vulnerabilities inherent to the most common communication protocols, operating systems, hardware, application systems, and operational procedures. Among all technologies, the Internet, which originally was created for communication where trust was not a characteristic, presents the greatest source of vulnerabilities for public information systems infrastructures. Here, a threat is a probable activity, which, if realized, can cause damage to a system or create a loss of confidentiality, integrity, or availability of data. Consequently, vulnerability is a weakness in a system that can be exploited by a threat. Although, some of these attacks may ultimately lead to an organization’s financial disaster, an all-out defense against these threats may not be economically feasible. The defense actions must be focused and measured to correspond to risk assessment analysis provided by the business and IT management. That puts IT management at the helm of the information security strategy in public organizations.
