Input Controls

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.

The entering of data is an important part of the computer operator’s daily routine. Computer operators may also have to take calls from customers complaining of computer system issues. The computer operator will diagnose the problem and then walk the individual through how to fix the situation. Should further help be needed, the computer operator will contact the necessary parties or advise the customer how to do so on their own.

Input: An input is when a computer receives data from external hardware such as a mouse, keyboard

The problems that may occur with information systems in documents not saved correctly and the old revision of the document has been updated mistakenly or the document been sent as a shortcut to another users desktop changes been made and other staff not been able to access these.

Using the tables from Task 1, design and implement suitable data entry forms which incorporate features to ensure the validity and integrity of data. You must include the following:

Input operation is external instructions that are put into computer data form. Two examples of Input would be a video camera and the videos another would be a keyboard and the characters that are used.

data integrity) are simultaneously explored, but this need not be the case when only considering

22. Which of the following features should not be there in an access control system?

9-16. Identify one or more control procedures (either general or application controls, or both) that would guard against each of the following errors or problems.

For example a clerk will only be able to access a limited amount of information, such as inventory at each store. The limitations will be different for an accountant or the mangers. All information will be protected with several different layers of security. The first layers will be simple hardware protection for access to the network; from there the security will increase with password protection and restrictions to users. (Merkow & Breithaupt 2006)

Problem 9-16 Identify one or more control procedures (either general or application controls, or both)

The concept of the ‘Garbage in and Garbage out’ can be highlighted in this stage because wrong input produces wrong output. So they needed to store the genuine and verified data in some storage device which could be used as an initial input for the new system, adding some new data’s if needed, enacting the data from any destruction and then finally arranging the data for an easy and friendly access to its users.
