Bibliography 13 .Introduction Cryptography is the science of writing in secret code and is an ancient art; the first documented use of cryptography in writing dates back to circa 1900 B.C. when an Egyptian scribe used non-standard hieroglyphs in an inscription. Some experts argue that cryptography appeared spontaneously sometime after writing was invented, with applications ranging from diplomatic missives to war-time battle plans. It is no surprise, then, that new forms of cryptography came soon after the widespread development of computer communications. In data and telecommunications, cryptography is necessary when communicating over any untrusted medium, which includes just about any network,
ANALYSIS OF THE INTERNET POLICY FOR GREEN SCREEN SOFTWARE Presented to Executive Management Group of Green Screen Software
ANALYSIS OF THE INTERNET POLICY FOR GREEN SCREEN SOFTWARE Presented to Executive Management Group of Green Screen Software - Quarterly Meeting in December - Prepared by Jia Yu Sven Rohloff Abhishek Kapoor November 25, 2005 MEMO Date: November 25, 2005 To: Executive Management of Green Screen Software From: Jia Yu Administrative policy manager Re: Submission of report on internet policies Here is the report regarding internet policies requested September XX, 2005 concerning the presentation of basic facts of internet policies for the special case of Green Screen Software. For this report, a large number of secondary data is used, mostly found through academic databases and public search engines. Recent evidence gathered indicates that our employees are using the internet for personal purposes during the working hours. These behaviours will result a loss of productivity, damage to our computer system and probable legal liabilities. In order to solve this problem, a internet policy at work place is recommended to be established. Resistance can be reduced by encouraging the participation from our employees. Also, Executive management should act as a good example to show their commitment of setting up such policy. If you have any questions, please contact me at (778) 858-1792 or [email protected]. I am happy to provide you with additional information if

There are several methods one can use to implement a business system. The two methods are parallel and cut-over. The implementation stage for Riordan Manufacturing project is a display of the crucial moments that make a project an achievement or a failure. The implementation stage tells all the details of modifications made operational. The beginning started after the system had been tested and accepted by the user. This is like a packing slip for the code files in your implementation. Make note if you have added/removed/renamed/etc. any classes/methods/member variables/functions/etc. state the language (or languages) in which you will implement your project, (1) list the names of the source and header code files that will contain your implementation, (2) list the classes and functions that will appear in those files, saying whether each class or function is declared or defined in that file, and (3) list the associations (for example, inheritance, ownership, reference counting, etc.), between the classes and describes how each association will be declared. An information system is an integrated collection of software components. Components can be tested individually or in groups, or the entire system can be tested as a whole. Testing components individually ensuring that a final product is closer to completion.. Integration and system testing is a must.. Operation of
Security System for Ad-hoc Wireless Networks
Security System for Ad-hoc Wireless Networks based on Generic Secure Objects Matei Ciobanu Morogan 2005 Ph.D. Thesis Kungliga Tekniska Högskolan Submitted as the partial fulfillment of requirements for the degree of Doctor of Philosophy at the Department of Computer and System Sciences, Kungliga Tekniska Högskolan Department of Computer and Systems Sciences Doctoral Dissertation Department of Computer and System Sciences Stockholm University / Royal Institute of Technology ISBN 91-7178-019-X i Abstract As computing devices and wireless connectivity become ubiquitous, new usage scenarios emerge, where wireless communication links between mobile devices are established in an ad-hoc manner. The resulting wireless ad-hoc networks differ from classical computer networks in a number of ways, lack of permanent access to the global network and heterogeneous structure being some of them. Therefore, security services and mechanisms that have been designed for classical computer networks are not always the optimal solution in an ad-hoc network environment. The research is focused on analyzing how standard security services that are available in classical networks can be provided in an ad-hoc wireless network environment. The goal is to design a security system optimized for operation in ad-hoc wireless networks that provides the same security services -
Types of IT Security Threats
In this report, I will examine various security threats, as well as methods through which these threats can be protected against. I will cover four threats in detail, these being; * Denial of Service * Password Crackers * Trojans / Worms / Viruses * Internal / External Threats Denial of Service Essentially, a denial of service attack, or DoS, is when a hacker attempts to make a system unusable by flooding the target with packets and communication requests. By doing this, the victim becomes saturated, is unable to handle the unusually high volume of traffic, and becomes unstable. There are a variety of ways in which an attacker may which to deploy a DoS against a target, each with varying outcomes. Some DoS will reduce the performance of its target, others may result in the victim coming to a complete standstill. Most modern DoS attacks are targeted at web servers. As already mentioned, there are a variety of differing types of DoS. I will examine a number of these, namely; Buffer overflow attacks, SYN attacks and DDoS. An attack using buffer overflow is a very simple concept. Attackers simply try to flood a system with more traffic than that system's buffer allows for. They do this by using traffic that the system does not flag as unusual. When a buffer attempts to store more data than it was intended to hold, the surplus will look to other buffers for space. This

The increasing number of websites flooding the internet has created the awareness for usability of web applications. According to (Bevan, n.d), an organization only meets its needs when a website meets the needs of its intended users. However, designers most often than not take the end users for granted and assume a software product is easy to use so long as they and their colleagues can use it which is never likely so. (Sharp et al., 2007) identify that, users want interactive products that are effective, efficient, safe, satisfying to use and easy to learn. This is why it is imperative for designers to
Website Review
Web Design (review) the different construction features used for the Ryanair website are tables, lists, action buttons, hyperlinks, hotspots, download speeds, email links and registration log in. Here are the following reasons why ryanair are using these constructions feature: Ryanair uses tables inside their website to separate things apart from each other and to layout data a lot clearer and to present the website in a more professional manner. Ryanair uses lists on their website to space the different countries apart instead of just bunching them together. Ryanair use action buttons on their website so that it's easy to navigate to another different webpage. Ryanair use hyperlinks on their website so that the user can access it for some latest information. Ryanair use hot spot on their website for easy linking to other websites and for easy browsing. Ryanair watches the download speed on their website because if the web page took very long to open, many of ryanair pass ticket bookers may forget about booking with ryanair and book with another airline instead. Ryanair uses email links on their webpage so that they can email information on any offers on flights or flight information to the user. The feature on this website is also good to use if the user wants to send and email directly to ryanair. Ryanair uses the login registration process on their website because
