For organizations, businesses both large and small, institutions and even individuals, the integrity, confidentiality, and availability of data is top among priorities to be addressed both in the present and moving into the future. Therefore, for businesses, organizations, and institutions, data security is absolutely important and has to be factored in the design of applications, information systems, and networks. This is a responsibility for all the above-named establishments and even for individuals. For the establishments, data security becomes an even bigger responsibility due to the fact that personal data has to be protected from leaking to unauthorized persons and parties. There are laws and regulations which protect data and its privacy and demand that specific data is not compromised.
The most important concepts when it comes to data are confidentiality, integrity, and availability. Availability is the plan to have the data accessible to the intended audience whenever the access is required and that data is not accessible to those people that access has been denied. Availability has more to do with uptime and the communication to the data and not the confidentiality of the data. Confidentiality has to do with the data being clearly permitted for viewing to specific individuals. The last concept of integrity specifically mandates that data will not be changed in any unauthorized or unexpected way. Any changes have to be expected and they have to be without inconsistencies or errors. These concepts are aimed at eliminating consequences arising as a result of unauthorized access, unauthorized modification and unavailability of data when the data is required.
This is whereas a general rule the access to data should be controlled to the point where the least amount of access is permitted for every user and the type of task he or she will be undertaking. This is called the model of least privilege and is applied to the concept of confidentiality and that of availability. To implement and satisfy the concept of integrity, the system which will handle the data should be tested rigorously just before the system is set running. The system should handle the data in such a way that it is never corrupted and that the incident report and assistance can be offered.
All these concepts are implemented in close scrutiny of the guidelines set about the security of data in the hands of an organization or a business. The legislation ensures that data is defined and the security measures to be accorded to each of the categories are in accordance with the bare minimum accorded by law. The regulations may be set by the federal state or by the local state and counties. The issue of regulation is a factor that cannot be ignored at all costs.
Besides setting up the systems with which to handle data, A business or an organization will have other concerns regarding the security that they have in their custody. This is especially so for the people authorized to handle the data. Remember that data may not only be about secrets on the operation of the business or the financial records or strategies, it also includes client data. Serious consequences would follow if the scenario of data getting leaked or lost.
On another different front altogether, data may be well secured but natural disasters like the hurricanes and the floods which can cause unprecedented damage. Data security will mean that such calamities are also planned for and the necessary measures are taken to avoid the unwanted. Other disasters are cases of a fire outbreak, accidental deletion of data, hard drive failure, power surges among others which can render data inaccessible or completely destroyed. These are also issues that are to be considered when setting up the system or choosing a model with which to take care of the data.
To deal comprehensively with the data, important questions should be answered and they are where and how data is to be stored, the responsibility of maintaining of the integrity of the data lies where what will be the best mechanisms to access the data and lastly what measures can be taken to ensure that the upon the occurrence of a disaster that the impact experienced can be minimized. By comprehensively answering these questions and carrying out the continuous evaluation, data security can be guaranteed.
