Looking back and forward: Improving Health Data Security in Utah
This document discusses health data security in Utah, looking back at its history and forward to future challenges. It notes that privacy, confidentiality, and data security have long been important principles, dating back to the Hippocratic Oath. Over time, computerization and increased access to data have improved functionality but also created new security risks. Recent high-profile data breaches have resulted in millions of dollars in penalties. Moving forward, greater central control over information systems will be needed to comply with regulations, but this may reduce flexibility and innovation. Improving security practices must be an integral part of system development rather than an afterthought. Overall costs for secure IT systems are expected to increase.

A computer network connects multiple computers and devices to allow sharing of resources and communication between users. There are three main types of networks - local area networks (LANs), metropolitan area networks (MANs), and wide area networks (WANs). LANs cover small physical areas like a home or office building. MANs encompass larger areas like a city. WANs have the largest geographical reach such as between countries. Common network architectures include client-server, where file storage and services are centralized on server computers, and peer-to-peer where computers directly share files and resources without a central server.

One of the most Costliest is data security. Where value addition might be very low but huge investment is required to safeguard it. Data security needs updates of malwares andย infringment policies.
In this information era, Security has become more difficult to define and enforce.
information security was limited to controlling physical access to oral or written communications. The importance of information security led societies to develop innovative ways of protecting their information. Recent innovations in information technology, like the Internet, have made it possible to send vast quantities of data across the globe with ease. However, the challenge of controlling and protecting that information has grown exponentially now that data can be easily transmitted, stored, copied, manipulated, and destroyed.
Within a large organization information technology generally refers to laptop and desktop computers, servers, routers, and switches that form a computer network, although information technology also includes fax machines, phone and voice mail systems, cellular phones, and other electronic systems. A growing reliance on computers to work and communicate has made the control of computer networks an important part of information security. Unauthorized access to paper documents or phone conversations is still an information security concern, but the real challenge has become protecting the security of computer networks, especially when they are connected to the Internet. Most large organizations have their own local computer network, or intranet, that links their computers together to share resources and support the communications of employees and others with a legitimate need for access. Almost all of these networks are connected to the Internet and allow employees to go โonline.โ
