In order to prevent both intentional and unintentional alteration, and destruction of information, any software application needs controls to ensure the reliability of data. Here are two specific controls per each one of the three data control categories, and how each control contributes to ensuring the data reliability in the format requested.
Control Category Specific Controls Contribution to Data Reliability
Input Controls Data checks and validation This control prevents the user from entering incorrect information that could result in an erroneous value to be processed. It will also compare, if possible for that field, the value entered with a list of acceptable values; If no match exists, an error is flagged. These input control methods

This prevents unauthorized access, modification, or disclosure of system data. The chance of fraud, or embellishment is reduced by limiting access to non-conflicting job duties, e.g. individuals who set up approved vendors cannot initiate purchasing transactions, and individuals who have access to claims processing should not be able to set up or amend a policy
Processing Controls Input error correction The program will monitor the user input and will notify immediately of a wrong action (like a key stroke the is not valid for the particular input), will create an error file that contains the data set that contains the error to be analyzed and investigated, or the entire batch of data will be rejected, if the errors cannot be attributed to an specific record, for the user to locate issues and resubmit a corrected set. Generating audit trails - transaction logs and error files Each transaction is stored in a log file that will be useful, in conjunction with the error files, in case one of the processes fails validation to go back and find out which process was to determine the cause of the

The fact that EAMs have been turned off for different periods could be an indication that there were some transactions that management did not want an audit record of them be created. The first thing auditors need to do is ensure that there is a strict control on any changes to the application programs. Any changes need to be documented, and authorized by the appropriate. The documentation needs to include a clear explanation of why the changes are needed, and how they will affect the functioning of the EAMs. Application program changes should be tested in a non-production environment to make sure the operation, including integration with the EAM is not degraded. Version numbers in the applications should match the number of changes
The two limitations are checking packets one at a time, and checking only some fields of the internet and transport headers. Checking packets one at a time is bad because packets will be examined one at a time, and cannot stop attacks such as DoS. Checking only some fields of the internet and transport headers is bad because will not examine all field of the internet and transport header fields, and cannot stop all attacks such as utilized attack.
Every piece of information must be traceable back to the data input that produced it. The main action of audit trail is captures a sources of all data items at the time of getting entrance into the system. The other constituent of input control and security involves data security rules and measures to protect data from being or lost or damaged. The records retention policy is the practice of storing documents in a safe location and making sure to see to legal requirements or business needs. Input security and control also involves the process of encrypting or encryption of data so only users with the code it software can read
Authorization controls to restrict access to authorized users. These controls are implemented with an access control matrix and compatibility tests.
...in order to properly secure the restricted data contained within the system. The software development team carefully explains the danger of compromised data both in the form of a technologically proficient employee along with the potentially greater and more damaging theft of data perpetrated by online hackers. Financial loss due to inadequate data storage and security is also explained to the client. The goal of this explanation is the realization that an increased preliminary investment may ultimately be significantly less expensive than a breach of an insecure system. In the event the client is unable or unwilling to modify the structure of the system, the recommended course of action is for the software development team to decline implementation of the system with consideration to the consequent damage to the repute of the software development organization.
Mandatory access control creates a classification of resources and allows access only to people of a certain security clearance. The controls are enforced by the operating system. For example, the operating system cannot convert a classified document to a lower classification without a formal, documented process of declassification by ...
These interfaces provide options to choose a role for the account and necessary controls to provide account requirements such as facility and the duration of the account. The Software system can immediately process these requests and drop them into other systems so that provisioning tasks can be initiated immediately. Proper tickets are created and automatic messages are sent to all approvers involved. Once all approval levels are recorded in the corporation’s main recording system, active directory accounts can be created or reactivated for the accounts. The software system, then informs the account holders, approvers and originators of requests through automatic email messages.
...h visual, Trace Precedents command tells what cell is affected , the cell that is selected an error checking command provides errors and gives explanations for why there was an error. On the excel document if there is an invalid data, data validation function can be applied and it instructs excel to circle invalid data. Lastly, when using watch window to monitor, you are able to view specific cells and monitor worksheets as soon as formula or changes that are made, that affect the outcome of watch cells. With that being said, these functions are important in any field ones desires to be in such as auditing, banking, or even running your own company; it gives more organization, accuracy and easy way to update any data if there are future changes.
... managed to introduce changes in the database they were spotted as intruder in the subsequent command. The results of the detection latency and performance overhead are mentioned both in normal conditions and heavy load conditions. The author finally concluded that “The detection coverage was 100%, if we consider the sequence of commands inside the transaction in reality” [Fonseca, 2008].
For any data system to fill its need, the data must be accessible when it is required. This implies the computing systems used to store and process the data, the security controls used to ensure it, and the correspondence channels used to get to it should work accurately. High accessibility systems plan to stay accessible constantly, counteracting administration interruptions because of energy blackouts, equipment disappointments, and system updates. Guaranteeing accessibility additionally includes preventing denial-of-service attacks.
What is a transaction? A transaction is an action(s) that the user does which when done correctly reads and or updates the contents of the database that they would like to change. The main purpose of any transactions is to:
a requirement intended to ensure that systems work promptly and service is not denied to authorized users.
...ll those helps managers to know if the process control is working or not, while the control process is contributing to successful of the current strategy.
Within the Oracle database control of data concurrency and consistency is vital because it may be a multiuser environment.
Input controls are used to ensure that the data entered into a system is correctly, completely, and is secure. The input controls can help the flow of data in a database to be the same format and easy to understand. There are many times of input controls, however the paper goes into detail about four types of input control which are: input mask, validation rules, source documents, and batch input. Without input controls there can be data integrity errors that could occur and cause information to be incorrect in the database. There are advantages and disadvantages to restricting user interfaces to limit a person ability of typing in too much information or maybe not enough information.
By observing very closely/ examining different kinds of accidental errors, this can be discovered that they will be again classified into couple of various groups. They will be errors committed by the developer and errors committed by the end user.
