The Importance of Data Security in Information Systems

QUESTION
The Importance of Data Security in Information Systems: highlight the importance of data security in information systems. Discuss the different types of data security threats and how to mitigate them.

ANSWER
1. Introduction
Given these issues, it is necessary to have a clearer understanding of data security and measures that can improve it. These concepts are not only important for computer scientists but a wide range of IT professionals. It is thus appropriate to provide an analysis of the data security area that focuses on concepts and problems rather than delving into technical detail.
In a related matter, the health information of individuals is now being stored and transferred electronically between health providers using an electronic health record (EHR). The sharing of this information has enormous benefits to patient care, and it can also be lifesaving in emergency situations. Yet these systems also bring new challenges for data security and the potential for breaches in patient confidentiality.
We cannot discuss data security and its importance to any given organization without also discussing the implications of data security in national and global systems. The events of September 11, 2001, and more recently, the Madrid and London bombings have led to increased requirements for intelligence and data sharing between government agencies. While this has clear benefits in crime prevention and national security, it does raise very serious issues about data security and the implications of unauthorized access.
Data security is a serious issue for many organizations these days. Unauthorized access to data can lead to serious financial losses and can damage an organization’s reputation. With the increasing reliance on data systems to store and retrieve information for decision support, the security of data has become more and more critical.
1.1. Definition of data security
The meaning of ‘data security’ is defending digital information, in opposition to data defense being the protection of data to make sure that it is not modified. Data security is designed to invoke certain aspects of data’s integrity – this meaning its accuracy and consistency, its confidentiality – meaning that only those who are authorized can access it or know it exists, and its availability meaning that the data can be accessed by those who need it. Confidentiality is preserved through the use of encryption preventing unauthorized users or viewers from interpreting the data. Integrity is closely related to confidentiality in its requirement that data is free from unauthorized alteration or destruction. As integrity relates to availability a date that cannot be accessed does not have integrity and thus timely and authorized access is also a necessity of secure data. This classification for aspects of data security provides a useful approach when considering how to defend data. We can decode that throughout the primary role of data security is to deny the access of unauthorized users to the data in question, this denial taking place through a variety of methods involving technology and procedural work. This is quite a basic way of viewing the intention of data security and the value of data ranging from person to person and organization to organization means that different data will have different requirements for the level security it needs. From simple features such as passwords on files for home users to complex and specific security measures in use for large organizations these methods are essential in denying access to data to those who should not have access to it. The next stage in data security’s main intention is the maintenance of said access denial, this is not enough to simply deny access on a one of basis someone failing to access data that they should not be able to is an occurrence that happens at all levels and the more damaging unauthorized data access is often occurrence that user will try repeatedly try to achieve. This requires the maintenance of an access denial stance and the prevention of unauthorized data access or in the recent examples of data security theory and build data recovery. The recovery of data that has been lost or compromised is an essential aspect of the availability importance of data today and the prevention of repeat data loss or compromise is the best way to maintain the state of data. Though not all data recovery is an act trying to recover data lost through being denied access, sometimes an incorrect alteration of data can cause integrity loss and in some cases attempts to alter or destroy data are the cause of why the data has been accessed in the first place.
1.2. Significance of data security in information systems
With such high stakes, it is clear that data security is crucial. Yet data and systems security is under constant threat from a wide variety of sources: internal and external, intentional and accidental. You mention intentional destruction and release of data is a constant and increasing threat. The recent huge growth in the use of the internet and mobile computing has led to a rise in security incidents and breaches from sources such as denial of service, viruses, and theft or interception of data in transmission. In the modern global environment, the value and vulnerability of organisational data means that it is a target as never before and the threats will continue to increase. This is certainly a case where the best form of defence is attack, and with security incidents becoming almost inevitable, there must be plans and resources for damage limitation and quick recovery.
Lost information can result in direct financial losses, but also in long-term competitive damage. The less tangible costs include lost productivity and goodwill, possible legal liabilities, and erosion of customer and shareholder confidence. In extreme cases, loss of data can lead to complete failure of the organisation. For example, a recent survey of UK companies revealed that 57% suffered from data loss sufficient to affect their business, and that of these, 43% never recover and 29% close down within 2 years. Similar figures have been reported in the USA.
1.3. Purpose of the essay
The purpose of this particular essay is to discuss the importance of data security in information systems. In doing so, a deeper understanding of the risks and solutions will be elaborated. The main focus will be on the threats to information systems, the impacts if security is compromised and what can be done to heighten security. This would explain why data security is of such importance when speaking of information systems, and seek to persuade the reader to believe the same. This is an important matter in the world we live in, as the technology age is upon us. More and more of our daily tasks are being simplified by information systems of all forms, and it is crucial to be aware of the vulnerabilities to these systems and how to protect the information within them. Failure to do so will result in far too many negative consequences, and by raising awareness of these issues we can go some way to preventing them.
