Essay on An Introduction to Access Control Mechanisms

The specific purpose of this paper is to describe the authentication process and to describe how this and other information security considerations will affect the design and development process for new information systems.

Each distributed DB perform some procedures to protect the data from any threats may occur through transactions. First is access control methodology which prevent unauthorized access to data. Second, inference control which prohibit users from inferring confidential data of other individuals using queries. Finally, flow control to prevent information from flowing to unauthorized persons in a way that violates organization policies.

Company must also develop a clear structure for granting employees access to sensitive information. Not all employees need such data in order to fulfill their everyday job responsibilities. For those who need admission to sensitive information, a strong authentication mechanism must be developed, which cannot be bypassed. This will ensure that only authorized users are accessing compromising data.

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

Other security elements are in reference to data recovery, database administration, handling a breach in security and administrative security policies such as access procedure, employee transfer and excessive user access. As I assume the role of the chief security officer, database designer, database administrator, and chief applications designer this project is very important to the armed services and the Virgin Islands National Guard as we strive to provide global security.

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.

This paper will discuss a better way to control user access to data is to tie data access to the role a user plays in an organization. It will cover the value of separating duties in the organization. Then discuss the value of using roles to segregate the data and system access needs of individuals in the organization. Then describe in detail why a role-based access control system (RBAC) would be the best way to accomplish this. Finally, how to handle distributed trust management issues for users going to or from business partner networks.

The analysis of the problem should take a day. At the analysis stage we determine the solution. The solution has been identified as the installation of the access control system. At this stage the system parts are identified; they include input, output, communication devices, power supplies, detection devices, intelligent panels, card readers, lock hardware, the actions and the response of the system in case of violation of the input requirements or failure of the system.

Information security is the protection of information against accidental or malicious disclosure, modification or destruction. Information is an important, valuable asset of IDI which must be managed with care. All information has a value to IDI. However, not all of this information has an equal value or requires the same level of protection. Access controls are put in place to protect information by controlling who has the rights to use different information resources and by guarding against unauthorised use. Formal procedures must control how access to information is granted and how such access is changed. This policy also mandates a standard for the creation of strong passwords, their protection and frequency of change.

“The practice of keeping data protected from corruption and unauthorized access” is known as data security (SpamLaw, 2011). The focal point of data security is the protection of

All workers of this organization oversee ensuring that data is secured appropriately. Senior administration oversees issuing and embracing this Security Policy. They perceive the delicate idea of the data that the association stores and forms, and the genuine potential mischief that could be caused by security occurrences influencing this data. They will along these lines give the most astounding need to data security. This will imply that security matters will be considered as a high need in settling on any organization choices. This will help Campbell Computer Consulting and Technology Company to assign adequate human specialized and budgetary assets to data security administration and to make a proper move considering all infringement of Security

If a user wants to extract data and if it contains sensitive information, the DBMS should mention an user friendly error message like "Cannot have access to this data" so that user will not try to dig the information further.

This abundance of sensitive data offers criminals with an even more wide range of openings to profit from stolen information and I.P. (Intellectual property). Also, overseas governments and crime organizations have incorporated hacking as one of their effective criminal tools at their disposal.

With advances in technology constantly happening, it can be hard to keep up with all of the latest trends. If organizations cannot keep up with the latest trends, it can lead to flaws in their security. Any flaws in security can have a detrimental effect on an organization’s database. Almost every organization has some sort of database, whether it is for maintaining customers, inventory, or vital information.

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.
