Information System Security
With growth, problems arise; and problems bring on solutions. As information system technologies become, now more than ever, a part of our survival, threats arise as well. The main focus of these threats is to invade our privacy and disrupt our function. Whether to steal our identity for criminal financial gain or just to play a prank to fill a wasted day, cyber crimes have affected people's homes as well as corporate headquarters. Nevertheless, society has become more aware of the existence of such activity, and is taking steps towards fighting these technological transgressions.The threats on today's information systems include, but not limited to, the following: Spy ware, viruses and worms, spam, cookies, PHISH scams, and malicious acts.A spy ware is a program that is installed on a computer with out the user's knowledge; in order to collect information on the user. [19] Spy ware uses the computer's processing resources in order to run, and in many cases causes the computer to become extremely sluggish or even totally unusable. [19] There are several types of spy ware; among which are ad ware (installed by advertisers), Trojans (collects personal information and passwords), key logger
Email viruses usually come in the form of an attachment to an email and, if opened, can rake havoc to the computer system, as well as spread through the user's address book. [2]CookiesCookies are small text files that contain user habits in viewing certain websites. [17]Hordes "The Hordes protocol engages multiple proxies for routing, in an anonymous way, a packet to a responder while it uses multicast services for routing, again in an anonymous way, the reply to the initiator. " [17]FreedomFreedom takes the information that is sent by the end user and encrypts it, then it routes the information through a private network. In today's world, information systems are become the most vital part of the organizational strategy towards achieving a competitive edge. [16]Virtual Private NetworksVirtual Private Networks, or VPN, allows for a secure transfer of data from one point to another across the internet, without being intercepted by outsiders. "Whether these applications are used for personal or business purposes, they can create a gateway for spy ware or malicious code to creep onto the employee's PC and the enterprise's network. Anyone who can monitor all information sent to or received by one particular protocol participant may act as an eavesdropper and record/compare all incoming or outgoing messages. [13] The problem with encryption, however, is that it does not prevent viruses and malicious code. Therefore, servers will not be able to download any spy ware onto the end user's information system.
