Access Controls And Access Control Security Essay

Constrained User Interface incorporates similar concepts of two other access control models that have been detailed, Role Base and Rule Base. Constrained User Interface is defined as a user’s ability to get into certain resources based on the user’s rights and privileges. These rights and privileges are restricted and constrained on the asset they are attempting to access. While this requires many levels of protection it provides limitations on the request access to the resources available within the organization.

Databases are the heart of the company. This is where all crucial company information is stored and can be accessed. Some databases are stored on site others in remote locations or using clouds. The information within a database can be manipulated in any way that the company needs it to be. Databases help to quickly search and retrieve information, it saves from data redundancy.

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.

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

Mandatory access control is a single user, normally the network admin, who is given access to the users’ rights and privileges. They control access policies and are also in control of choosing which objects and what systems each individual user has access to and what they do not have access to. The access is made in the form of different levels. Each system and all folders containing information are put into a specific classification. The user will be in a certain classification that will only allow them to access data

Describe how and why authentication credentials are used to identify and control access to files, screens, and systems. Include a discussion of the principles of authentication such as passwords, multifactor authentication, biometrics, and single-sign-on.

mandatory and discretionary access control policies. ACM Transactions on Information and System Security, Vol. 3, No. 2.

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.

An access control example in my community is doors. Having a lock door, will cover access to your home, which is one of the first steps in securing your home. A properly set up fence, will make it even more difficult for someone to roam in your yard. If someone you do not know is inside your fence, it can easily alert you that a potential problem is arriving. Shrubs are another factor in access control. Shrubs can make it very difficult for someone to view inside your home. There are shrubs that can grow up to 15 to 20 feet height. Having many shrubs in your yard can make access to your home feel more of a challenge, which is how a lot of homes in my community are set up.

As a business owner, you want to make sure you keep your business secure both during and after working hours. One tool you can use to keep your business as secure as possible is an access control system.

- DBA security – Controlling the access on the DB level can also serve as a mechanism to protect sensitive data. In this type, there is always an administrator who controls the process of Account creation, granting access, revoking roles and assigning appropriate security level assignment.

Role based access control is an ideology through which access to systems is restricted based on authority given. It is used by organizations with a relatively large number of employees ranging from five hundred to one thousand and above (Sieunarine & University of Oxford, 2011). This is implemented through the mandatory access control or through the discretionary access control. These are the only two ways through which role based access control can be implemented.

Databases allow us to easily store and retrieve data in a purely digital format. The strength of this is that large amounts of data can be stored and retrieved with minimal effort on the part of the user. Opposed to manually flipping through files, one can quickly pull up the requested data through a computer program. Many systems that were conventionally paper and file based have been converted to a digital format which are now stored in one or more databases.

According to Rouse (2006), “Computer databases typically contain aggregations of data records or files, such as sales transactions, product catalogs and inventories, and customer profiles” (Rouse, 2006). Databases can hold a sufficient of information that are deemed

Access control: The ability to permit or deny the use of an object (a passive entity such as a system or file) by a subject (an active entity such as a person or process).
