Aspects Of Database Security Information Technology Essay

Aspects Of Database Security Information Technology Essay Many native methods of providing Database security have also been discussed along with a survey of database threats issues and its remedies. Mechanisms are discussed that propose strengthening the database security. It seems desirable to get an understanding of the complete set of security problems faced and their problems up-to-date to devise better methodologies for database security issues. The research study regarding Database Security is organized as follows: Section 1 highlights the native methods of Database Security which have been employed. Section 2 describes the threats faced by databases and Section 3 discusses varies proposed remedies to the Database security issues. Improper safeguarding of data might compromise database confidentiality, its availability and integrity. In order to prevent this, it is very important to form a comprehensive ‘database security’ concept [term paper link]. Importance of Data The security of data has always been an issue, but wi th the increase of applications relying more on databases to store that information, the threats to the security have increased manifold. Security of data is a crucial issue today then ever and the importance of it is clearly understood as well. The three main objectives of Database security include Confidentiality, Integrity and Availability [1]. The databases have to be secured in any case since they contain bulk amount of data both confidential and public. The loss of integrity of data can not only have disastrous affect for a specific user, but the reputation of the whole organization comes at stake. Methods to perturb original data and are required in which data is converted to some anonymous form, in cases where the privacy of data itself is of utmost importance. Anonymization in that case is carried out in such a way that the original data integrity and its relationships are maintained while the data is perturbed for analysis. Threats to Database Databases today face a growin g risk of threats and vulnerabilities. Security breaches are typically categorized as unauthorized data observation, incorrect data modification, and data unavailability. Unauthorized data observation results in the disclosure of information to users not entitled to gain access to such information [2]. In case of unauthorized data observation, the data is seen by users for whom that data in not intended. For incorrect data modifications, once the data in the databases is modified, its integrity is lost and then the proper usage of data cannot be carried out. The true information is not available when it is needed. Countermeasures to Threats Some countermeasures that can be employed are outlined below: – Access Controls (can be Discretionary or Mandatory) – Authorization (granting legitimate access rights) – Authentication (determining whether a user is who they claim to be)ÂÂ   – Backup – Journaling (maintaining a log file – enables eas y recovery of changes) – Encryption (encoding data using an encryption algorithm) – RAID (Redundant Array of Independent Disks – protects against data loss due to disk failure)ÂÂ   – Polyinstantiation (data objects that appear to have different values to users with different access rights / clearance)ÂÂ   – Views (virtual relations which can limit the data viewable by certain users) [3].

International Business Management Research Paper

International Business Management - Research Paper Example Australia possesses remarkable diversity of life forms which is unique compared to rest of the world, its diverse culture and lifestyle reflects its liberal democratic traditions and migrants. According to Aswathappa (2010) the environment of international business is regarded as the sum total of all the external forces working upon the firm as it goes about its affairs in foreign and domestic markets. Understanding of the Australian business culture can relieve tension in a business transaction and make it beneficial and enjoyable for both business parties (Nolan 1996). Australia enjoys political stability and has a federal system of government with powers generally distributed between the Federal Government and State Governments all of which are governed through elected Parliaments. Australia’s foreign investment policy encourages FDIs which are consistent with community interests and they are required to register and get approval from FIRB in certain categories like proposa l to establish new business, investment in sensitive sectors, acquisition of assets and shares and real estate (Feslers, 2010). According to AMB Country Risk Report (2010) Australia in a Country Risk Tier (CRT) – 1 country with very low levels of economic, political and financial system risk and experienced 18 years of uninterrupted economic expansion. With such rich natural resources and diversity in socioeconomic and political background, Australia is the best place to start a new business as stated by World Bank report and also due to low risk factors. Introduction The globalization process has made it compulsory for the companies to expand their business operations beyond its national boundaries and enter the international market and to operate in global market. As the global economy continues to develop, managers need to learn the process of working and operating business in international arena in the same way as they do in their own backyard (Lane et al, 2005). Successf ul corporations embrace a global perspective and philosophy to survive and prosper in the international environment which is a challenge for the companies to deal with the dynamic environment (Punnett, 2010). International business as a field of study and practice encompasses that public and private business activity affecting the persons or institutions of more than one national state, territory or colony. The effect may be in terms of their economic well being, political status, conviction skills or knowledge, International business differs from the purely domestic because it involves operating effectively within different national sovereignties, under widely disparate conditions, with peoples living with different value systems and institutions, legal systems, etc. In order to make a movement or take a decision for international expansion, it is important and essential to make a strategic approach taking into consideration the domestic environment of the country selected for the expansion, the socio economic environment, the structure of the international economic and political system, and company resources. This paper presents the possibilities and factors to conduct business in Australia and provisions and facilities in form of encouragement like certain exemptions provided the host country to promote foreign investments.

Windows HPC Server 2008 - Research Paper Example This paper discusses the main aspects of Windows HPC Server. This paper will outline the windows HPC Server’s basic working structure, its advantages and disadvantages, its current uses and new features of this server technology. OVERVIEW OF WINDOWS HPC SERVER Microsoft Windows HPC Server (HPCS) is a modern technology based generation of HPC (extreme performance computing) that offers performance, enterprise-level services and extendibility for an extremely prolific HPC framework. Additionally, the HPCS offers a comprehensive and incorporated cluster arrangement encompassing the task or job scheduler, operating system, cluster management, message passing interface v2 (MPI2) support and scrutinizing elements. Moreover, the latest developed Windows Server ® 2008 64-bit, HPCS ranges to thousands of CPU processing cores and comprises a management console that facilitates practically maintenance and checking system strength and constancy. In this scenario, the job scheduling agil ity and interoperability facilitates incorporation in Windows-based HPC platforms maintains service-oriented architecture (SOA) or group workloads. Furthermore, Windows HPC Server 2008 offers a lot of facilities such as improved efficiency, simplicity of use and scalable performance that is why it is the most effective solution for Windows platforms (Microsoft, 2008) and (Microsoft Corporation., 2008). HOW IT WORKS This section presents an overview of the working and functioning method of Windows HPC Server. This section will discuss that how Windows HPC Server works? Basically, Windows HPC Server is designed on a group of servers that comprises a single head node and one or more compute nodes as stated in the below given Figure 1. In this scenario, the main head node that currently offers switching from fail component to backup component using Windows Server 2008 Enterprise accessibility services, SQL Server powers and clustering is responsible for managing all the rights to access the cluster resources as well as it is the particular position of operation, organization and job development in support of the compute cluster. Moreover, Windows HPC Server offers a lot of tools to manage accessible Active Directory, directory service-based arrangement for security, complete functions and handle account. One major example of these tools is System Center Operations Manager (Microsoft, 2008) and (Hand, 2010). Figure 1- Windows HPC Server Working Arrangement Image Source, (Microsoft, 2008) The installation process of Windows HPC Server encompasses mounting the OS on the main head node, combining it to an Active Directory domain, and afterward applying the HPC Pack 2008. In this scenario, there is a page named as â€Å"To Do List† which outlines the steps needed to finish the setting of our compute cluster.
