O crescimento e proliferação da Internet nos últimos anos tem trazido à tona vários problemas relativos à segurança e operacionabilidade das máquinas de universidades e empresas. Inúmeras invasões são realizadas anualmente. Entretanto, a grande maioria delas não possui registro algum, sendo muitas vezes de total desconhecimento do administrador local. Para prover soluções para estes problemas foi realizado um estudo, aqui apresentado, que tem como principal objetivo propor uma filosofia de gerência de segurança. São utilizados para isso conceitos de gerenciamento de redes como SNMPv2, aliado à implementação de um conjunto de ferramentas que garantam a integridade dos vários sistemas envolvidos. O resultado foi um sistema denominado CUCO1, que alerta sobre tentativas de ataque e situações de risco. CUCO foi projetado para permitir a um administrador, protegido ou não por uma firewall, dispor de um controle maior e melhor sobre acessos e tentativas de acessos indevidos à sua rede. O sistema usa uma estratégia de monitoração de eventos em diferentes níveis e aplicações, tentando com isto detectar e alertar a ocorrência de ataques tradicionais. Também está incorporado um bloco de funções que visam identificar um agressor situado em algum lugar da Internet, e obter maiores informações sobre ele e o domínio onde esta localizado. / The Internet increase and proliferation in the last years has brought a lot of problems related to the security and handling of hosts in universities and corporations. Many break-ins are done each year, without any record or knowledge by the site’s administrator. To give solutions to this problems was made up a study, here presented, has as the main goal the proposal of a security management philosophy. Are used network management concepts, joined with a toolkit to ensure the integrity of many systems envolved. The result was a system named CUCO2, that alerts about attacks and risks situations. CUCO was designed to allow an administrator, protected or not by firewall, to have a bigger and better access control in his network. The system uses an event monitor strategy in different levels and applications, trying to detect and alert the occurrence of common attacks. Moreover, it is also incorporated by a set of functions that attempt to identify aggressor’s location in any place in the Internet, and get information about him and the domain where he is located.

To perform their business activities effectively, organizations rely heavily on the use of information (ISO/IEC TR 13335-2, 1996, p 1). Owens (1998) reiterates this by claiming that all organizations depend on information for their everyday operation and without it business will fail to operate (Owens, 1998, p 1-2). For an organization it means that if the right information is not available at the right time, it can make the difference between profit and loss or success and failure (Royds, 2000, p 2). Information is an asset and just like other important business assets within the organization, it has extreme value to an organization (BS 7799-1, 1999, p 1; Humphreys, Moses & Plate, 1998, p 8). For this reason it has become very important that business information is sufficiently protected. There are many different ways in which information can exist. Information can be printed or written on paper, stored electronically, transmitted electronically or by post, even spoken in conversation or any other way in which knowledge and ideas can be conveyed (URN 99/703, 1999, p. 2; Humphreys, Moses & Plate, 1998, p 8; URN 96/702, 1996, p 3).It is, therefore, critical to protect information, and to ensure that the security of IT (Information Technology) systems within organizations is properly managed. This requirement to protect information is even more important today, since many organizations are internally and externally connected by networks of IT systems (ISO/IEC TR 13335-2, 1996, p 1). Information security is therefore required to assist in the process of controlling and securing of information from accidental or malicious changes, deletions or unauthorized disclosure (Royds, 2000, p 2; URN 96/702, 1996, p 3). By preventing and minimizing the impact of security incidents, information security can ensure business continuity and reduce business damage (Owens, 1998, p 7). Information security in an organization can be regarded as a management opportunity and should become an integral part of the whole management activity of the organization. Obtaining commitment from management is therefore extremely important for effective information security. One way in which management can show their commitment to ensuring information security, is to adopt and enforce a security policy. A security policy ensures that people understand exactly what important role they play in securing information assets.

Information classification deals with the handling of sensitive information, such as patient records and social security information. It is of utmost importance that this information is treated with caution in order to ensure its integrity and security. In Sweden, the Civil Contingencies Agency has established a set of guidelines for how governmental agencies should handle such information. However, there is a lack of research regarding how well these guidelines are followed as well as if the agencies have made accommodations of these guidelines of their own. This work presents the results from a survey sent to 245 governmental agencies in Sweden, investigating how information classification actually is performed today. The questionnaire was answered by 144 agencies and 54 agencies provided detailed documents of their classification process. The overall results show that the classification process is difficult, while those who provided documents proved to have good guidelines, but not always consistent with the existing recommendations.

M.Tech. / Information is a company’s greatest asset that is continually under threat from human error, technological failure, natural disasters and other external factors. These threats need to be identified and quantified and their relevant protection techniques need to be deployed. This research will allow businesses to ascertain which of these data protection strategies to embrace and deploy, thereby highlighting the balance between cost and value for their business needs. Every commercial enterprise should understand the business value of their data and realise that protecting this data is of utmost importance. However, company data often resides on different mediums, in different locations and implementing a data protection strategy is not always cost effective in terms of the cost of storage mediums and protection methods. The challenges that businesses face is trying to distinguish between mission-critical data from other business data, excluding any non-business or invaluable data that resides on their systems. Thus a cost-effective data protection strategy can be implemented according to the different values of business data. This research provides a model to enable an organisation to: · Utilise the model as a framework or guideline in determining a strategy for protection, storage, retrieval and preservation of business critical data. · Define the data protection strategy to meet the organisation’s business requirements. · Define a cost effective data protection solution that encompasses protection, storage, retrieval and preservation of business critical data. · Make strategic decisions based on an array of best practices to ensure mission-critical data is protected accordingly. iii · Draw a conclusion between the costs of implementing these solutions against the real business value of the data that it protects.

Continually the number of transactions carried out electronically via the internet has grown, as well as the number of users of IT (information technology). In the same way are accruing transactions that may be at risk in terms of information security as well as an increasing number of security incidents threatening financial gain or thefts of sensitive information. Attackers carried out attacks in order to make financial gains using more sophisticated methods, sophisticated not only using information technology but also using social engineering techniques. This growing trend is known about by governments and measures are being taken to help increase the information security of the state. This is evidenced by the fact that the European Parliament recently approved the following Directive Directive of the European parliament and of the council concerning measures to ensure a high common level of network and information security across the Union and the ensuing law on cyber security (Act No. 181/2014 Coll.) adopted by the Parliament of the Czech Republic in the summer of 2014. This act orders organizations which are maintaining critical infrastructure to implement a system to evaluate cybersecurity events (user behavior). So far no unified approach to implement such systems has been defined. Author defines standardized methodology for implementation of systems which evaluate user behavior with focus on optimization of data which these systems have to process to ensure their efficient functionality.
