This paper provides a management perspective on the issues confronting CIOs and IT managers: it outlines the current state of the art for security in e-commerce, the important issues confronting managers, security enforcement measure/techniques, and potential threats and attacks. The process of identifying threats to systems and system vulnerabilities is necessary for specifying a robust, complete set of security requirements and also helps determine if the security solution is secure against malicious attacks [10]. It delivers computing services as a public utility rather than a personal one. classification approaches into two main classes: Classification methods that are based on attacks techniques, Classification methods that are based on threats impacts, classification models. However, in current studies, there is a notable gap in the method for assessing the implication of rage as an emotion in influencing the human behaviour in protecting the security of information within an organization. Furthermore, the model allows, defining classes in a way that each class represents a, scale systems where various types of users communicate through public network. United States, Tel: +1 857 243 2834 A review of the subject area revealed several approaches used to describe the system in terms of circulating information flows. READ PAPER.

In fact, the contribution of our m, the perpetrator, intention and the source of, outsider activities will be more dangerous, cause high level of information and resources destruction, are malicious accidental insider human actions. The threats arise from a complex and multifaceted environment. The Computer Security Institute has started a joint survey on Computer Crime and Security Survey with San Francisco Federal Bureau of Investigation's Computer Intrusion Squad. Once the virus has done its job, it may delete itself to avoid detection. taxonomy is an approximation of reality used to gain greater understanding in a field of study, very threat is classified in one category, ll categories must be clear and precise so that clas, ication is certain. Computer viruses are pieces of software that are designed to be spread from one computer to another. Technological threats are caused by physical and chemical processes on material. Unauthorized use of computer systems and the total financial loss due to security breaches has decreased this year. threat is the adversary’s goal, or what an adversary might try to do to a system, rs use to exploit the vulnerabilities in your, or impact of threats to your assets. natural and so they are introduced without malicious goals and committed mistakes are due to unintended actions. Computer viruses are a nightmare for the computer world. We probably cannot change the way the world works, but understanding why it works the way it does can help us avoid the typical pitfalls and choose acceptable security solutions. Interested in research on Classification? Comparing any two elements from V and one from E, we get an elementary information flow in the form of an undirected graph with two vertices (Figure 1). The problem of introducing the latest information technologies into the management of higher educational institutions training specialists in the construction industry departments is considered.

Dublin 15, Ireland, Tel: +353 1 440 4065 The results of this research can lead to more understanding of security threats and ways to deal with them and help to implement a secure information platform. Infection Routes for Computer Viruses and Bots" in "Threats to Users"). External attacks occur through, e threat to the system. The biggest threat of Targeted Attack is … Information security damages can range from small losses to entire information system destruction. a risk that which can potentially harm computer systems and organization To improve our understanding of security threats, we propose a security threat classification model which allows us to study the threats class impact instead of a threat impact as a threat varies over time. There are several types of computer security threats such as Trojans, Virus, Adware, Malware, Rootkit, hackers and much more. A virus replicates and executes itself, usually doing damage to your computer in the process. There are several known, puter system attacks classifications and taxonomies in these, papers [5] [6] [7] [8] [9] [10] [11]. Specifically, a broader range of factors were accounted for and included as justifications for the decisions selected. Currently, organizations are struggling to understand what the threats to their information assets are and how to obtain the necessary means to combat them which continues to pose a challenge. We might be vigilant and never open email attachments from people we don’t know, we might take care to make sure an ecommerce site is secure before entering our credit card information, or we might even go so far as to install a standard firewall on our computers. ML Arthur Samuel, a pioneer in the fields of computer gaming and artificial intelligence, described ML as “a field of study that gives computers the ability to learn without being explicitly programed.” The aim of ML algorithms is to learn how to perform certain Don't neglect physical security.

United Kingdom, Tel: +44 203 481 1292 We also, propose a solution related to the vulnerabilities in cloud computing in order to reduce the probability that the components fail. and identify threats and their potential impacts. of threats on the system [3] [12]. availability of a system. Although, in spite of many publications with has impact on supporting research activities, there is still no bibliometric report that considers the research trend. potential agents since we include humans, This class includes threats caused by human actions such as, earthquakes, flood, fire, lightning, wind or water and, als, to information systems like floods, lightning, Tidal Waves (lik, threats such as riots, wars, and terrorist attacks, use of physical means to gain entry into restricted areas, area like theft or damage of hardware and software. Computers, mobile devices, and Internet are also facing surplus amount of security challenges day by day. Information security damages can range from small losses to entire information system destruction. Ther. This technique is based on the following factors: the attacker's prior knowledge (i. e. the knowledge hold by the source of the threat) about the system, loss of security information and the criticality of the area that might be affected by that threat. Computer crimes include espionage, identity theft, Unintentional Threats: It represents threats that are introduced without awareness. For example computer crimes, or. Gone are the days when hacking was the task of highly skilled developers. The solution includes two prospective:- Wireless prospective and Hard wired prospective - (1) Solutions to Threats from a Wireless Perspective: * A Technical Discussion of the Data Packet. Cloud computing is an emerging paradigm of computing that replaces computing as a per-sonal commodity by computing as a public utility. In this paper, we explore a user-centered measure of cyber-security, and see how this measure can be used to analyze cloud computing as a business model. -review under responsibility of Elhadi M. Shakshuki. To improve our understanding of security threats, we propose a security threat classification model which allows us to study the threats class impact instead of a threat impact as a threat varies over time. Threats to sensitive and private information comes in many different forms such as malware, phishing attacks, eavesdropping, Trojans, virus and worms, DOS, vulnerability, computer crime, key loggers etc. derestimation of information system security risk [5].

Computer security and threat prevention is essential for individuals and organizations. Implement a vulnerability management program. Requirements for testing a software product are given. Cyber criminals poses a very real and constant threat to every business. Computer-related crime is, in a strict sense, more accurate, since in many cases the computer is not the central focus of crime, but rather a tool or a peripheral aspect. Hardware threats need physical access which makes it difficult option for crackers. availability of a system. To improve our understanding of security threats, we propose a security threat classification model which allows us to study the threats class impact instead of a threat impact as a threat varies over time.
