Information Technology And Its Impact On The Security

T.J.X. was the leading fashionable brand name, off-price product retailer in the U.S. In 2013 the company’s net sales reached $27 billion, increased by 6% compared to the same period in 2012. In 2007, the company was revealed by the investigating authorities that their database had been penetrated by hackers for 1.5 years, and been causing 94 million debit/credit card and customers’ personal information stolen around the world of its 2,500 branch stores.

Wireless security in 802.11 is less robust and has many security flaws that can be exploited by an attacker. Security best practice for wireless networks depends on a defense in depth strategy, with five control layers:

With the increasing dependency on wireless networks, the need for proper reliability analysis for Mobile ad hoc networks (Manets) is also increasing. Failure of Manets in areas like warfare, nuclear reactors, medical equipment and airplanes can lead to catastrophe. Unlike traditional networks, measuring the reliability of Manets is a tedious task as it involves dynamically changing topology. The existing methods for calculating reliability use two terminal analysis as the basis for calculation. It uses the same method used for traditional computer networks to calculate reliability. However, the method is not very efficient when it comes to the wireless networks as they are far different from traditional networks. It is also a time consuming task to identify all the nodes and links in a wireless network as nodes move freely in the network. In This paper, We are going to discuss about NLN(Node-Link-Node) technique which reduces the complexity of analyzing the reliability in Manets.

Abstract -This paper addresses the internal and the external security challenges in organizations that implements wireless networks. Distributed security is designed to provide a more secure data communication among faculty members, staff and students. A description of the technique used to protect and keep PC 's up and running is illustrated with applications.

MANETs (Mobile ad-hoc network) is defined as autonomous collection of wireless mobile nodes that are self-configure to construct a network that can communicate over relatively bandwidth constrained wireless links.

The Oxford American Dictionary of Current English defines admonition as “to reprove. Urge. Give earnest advice to. Warn”. Understanding this how do we employ admonitions systems to information technology to make it more useful in-regards to Network and system security? Using admonition software we are attempting to create an environment that will either prevent data from being in-advertently distributed across networks. Act as a deterrent to those trying to access the network illegally. Or warning users of the potential harm their actions may cause. In developing an IT security strategy,

Mobile devices such as smartphones and tablets have allowed major productivity in the field and in the office and are starting to become an integral part of the business lifestyle. Although their intelligence allows greater productivity, it also makes them vulnerable to attack. A network is only as secure as its weakest link.

In today’s computer based world there are several potential and devastating threats like hackers, viruses, worms, and Trojans etc. to our computers, networks, and confidential information. So as to protect any computers, networks, and confidential information the installation of security applications is vital and hardware systems to protect our confidential information, computers, and networks. Some of the most popular Internet security systems are firewalls, intrusive prevention system, intrusive detection system, access control, and cryptographic tools and processes. However, there is no Internet security application or

In the past few decades, personal privacy information is one of the world biggest things that people pay attention to it. With today modern technology, information security has become one of the most significant careers in the industries, and organizations assets, which appropriately need to protect the information. It has created different types of positions in the organizations and companies that can fit in a global business as a professional career. By using the operating systems through the internet, especially computer networks, security systems, or cellphones, business relies on Information Security or Information Technology to conduct in companies. So, the careers in the computer science or IT field are very a world wide spread use. The organizations are working and practicing together to ensure that IT can understand the requirement of business needed for the security systems. With the growth of using information system, it increases the concerns and attention about information security based on the perspective theory that views this profession in many different perceptions. Therefore, the approaches of this field is targeting from different perspective that provide insights about the technology systems can go through businesses, becoming more importance and need the protection from this profession.

It’s fair to say the environment of the healthcare industry is always in the midst of constant turmoil. The industry is a complex equation built on ever-changing government programs, rapid advances in medicine and technology, and new business combinations between and among health-care providers and payers. Leaders of a healthcare organization must be equipped to adapt to the continuous chaos or face defeat. Information security and privacy is a fundamental component of a successful and efficient healthcare environment. The coming year will be a busy one for lawyers, compliance officers, privacy officers, and senior management as they must stay above the game when it comes to privacy and security. I will explore three trending issues and concerns relating to healthcare privacy and security. My hot topics include the use of big data and its implication, the evolving risks of cyber security, and health research and de-identification.

There has been extensive literature related to the security in wireless ad-hoc networks over the last two decades. There are several methods to increase the security other than trust management. Important among them are surveyed here.

IT security also know as computer security or cyber security or Infosec, is the process of protecting a computer system from the different types of theft or different types of damages to the hardware, software or data stored in that system as well as from the interference or alteration of the services provided by the system.

Information technology is becoming an increasingly important consideration in our Nation’s security. There is so much information can be easily accessible, yet terrifyingly detrimental to an individual’s identity or financial security if it lands in the wrong persons hands. Luckily, the National government started to realize this early on and have since enacted several laws in order to help protect certain groups. This paper will cover three of these laws, their scope and rationale as well as a case study. This research is being done with the intent of establishing the importance of these laws by discussing the potential consequences if these laws were not enacted. The paper will conclude with a generalized discussion of the

Wireless networks should be protected to safeguard sensitive information. Several practices can be implemented to protect wireless networks.

Mobile ad hoc network is decentralized form of network. The network is ad hoc because it does not rely on a preexisting infrastructure, such as routers in wired networks or access points in managed (infrastructure) wireless networks. Instead, each node participates in
