The World Of Computer Systems

Sadly, there is no way to alleviate the numerous amounts of threats that haunt networks and computers worldwide. The foundation and framework for choosing and implementing countermeasures against them are very important. A written policy is vital in helping to insure that everyone within the organization understands and behaves in an appropriate manner with regards to the fact that sensitive data and the security of software should be kept safe.

Formal user access control procedures must be documented, implemented and kept up to date for each application and information system to ensure authorised user access and to prevent unauthorised access. They must cover all stages of the lifecycle of user access, from the initial registration of new users to the final de-registration of users who no longer require access. These must be agreed by IDI. User access rights must be reviewed at regular intervals to ensure that the appropriate rights are still allocated. System administration accounts must only be provided to users that are required to perform system administration tasks.

Individual users play an important role in any form of institution or organization but concerns are raised about the security. The network administrators clearly lay down a set of rules, regulations and protocols that an individual user has to agree accordingly upon which part of the resources and what class of service that the user can obtain.

Access control refers to the mechanisms that identify who can and cannot access a network, resource, application, specific action.

The framework of security policy is defined to construct a structure by the help of which policy gaps can be identified in an easy manner. A system specific policy would assist to ensure that all employees and management comply with the policies. This is also used to maintain the confidentiality for user authentication would assist in the confidentiality aspect of security, maintain integrity (There are several limiting rules or constraints which are distinct in the relational data model and whose work is to maintain the data’s accuracy and maintain its integrity.), availability and authenticity of the system. Access controls are a collection of mechanisms that work together to create security architecture to protect the assets of an information system. One of the goals of access control is personal accountability, which is the mechanism that proves someone performed a computer activity at a specific point in time. So, the framework acts as the guideline

In today’s IT world every organization has a responsibility to protect the information and sensitive data they have. Protecting data is not only responsibility of security and IT staff but every individual is involved in protecting the information. The risks to information security are not digital only, but it involves technology, people and process that an organization may have. These threats may represent the problems that are associated to complex and expensive solution, but doing nothing about these risks is not the solution.

Any enterprise has to pay special attention to computer security. Computer security is a field that is concerned with the control of risks related to computer use. A primary focus should be on the external threats to the computing environment. In enterprise with branches cross country, it is important to allow information from "trusted" external sources, and disallow intrusion from anonymous or non-trusted sources. In a secure system, the authorized users of that system are still

The task of implementing a protection scheme that will provide controlled access to specific files in a system is not only an important but also a necessary task to ensure that the integrity as well as the availability of that file is maintained throughout. This paper is designed to put into perspective a protection scheme to facilitate the scenario where a system has 5000 user and 4990 of those users will need to have access to a particular file within the system. It will also provide clarity on Access control list (ACL’s) their roles as well as the different flavors available. It will also try to prove that proper implementation and utilizations of groups within a security scheme provides not only organization and

Data Confidentiality is not enough for secure data transmission in the military environment. Flexible and Fine-Grained access control is also required to make data more secure for the military environment. The information about the particular organization is required to be protected. In this case, access control of sensitive data is done by allowing users to access the data based on their roles. For example, the information about the colleges will be viewed based on their roles such as students, faculty, and higher level

Identity and Access Management (IAM) is a vital part of any organization’s security. Quite often, it is overlooked or not deemed important enough to invest in. It is very important for all employees, new and existing, to be given the proper access to the resources they need, and to be restricted from accessing resources they do not need, in order to perform their job. If the wrong access is given, an employee can either accidentally or intentionally change or destroy company data. Furthermore, a weak IAM policy leaves an organization open to external attacks. IAM is one of the most important, if not the most important, part of computer security.

As the use of computers, databases, and technology in general, security has grown to be a powerful tool that has to be used. The threat of outside sources intruding and exploiting crucial information is a threat that is present on a daily basis. As a part of creating and implementing a security policy, a user must consider access control. Access Control is a security tool that is used to control who can use or gain access to the protected technology. Access control security includes two levels; logical and physical. Though database intrusions can happen at any moment, access control provides another security barrier that is needed.

The most important goal of any access control model is to provide a verifiable system that guarantees the protection of any information from being accessed by an unauthorised party; in line with some defined security policies (Ausanka-crues 2006). Many access control models have evolved over time that manage access to resources in the organisation. With each one leveraging on a particular element of security. The Bell- Lapadula model for example focuses on Confidentiality; while the Biba

The intent of this security proposal is to ensure the ongoing protection and data security for a government agency's data center. Security and access privileges will be defined at the role and department levels, with added authentication for system administrators and members of the IT staff. Role-based access to this government facility will be tracked continually and reported using real-time log reporting and analysis (Amsel, 1988). This role-based approach to managing security will provide for inclusion of authentication, detection and deterrence in the areas of social engineering, firewalls, Virtual Private Networks (VPNs), authentication, security protocols and vulnerability assessments.
