...Security Threats Computer security is no longer just an organization’s concern but everyone’s who uses their computer to access the internet. Anyone who uses their personal computer to access the internet faces potential security threat. This document will identify all the potential security threats on a personal computer and some techniques an attacker might employ to access information on the file system. Security threats can be broadly classified into outside and inside threats. Organization may be exposed to viruses and worms as a result of employees not following certain practices or procedures. Intruders are also a big security threat—they hack into large networks to steal private information like social security numbers or credit card account information. Closely related to the intruder security threats are the “Insiders” who are more dangerous in many respects than outside intruders. Insiders have the access and knowledge necessary to cause immediate damage to an organization. Most security is designed to protect against outside intruders and thus lies at the boundary between the organization and the rest of the world (Conklin & White). The various techniques an attacker might employ to access file systems are, Trojan horse programs which are a common way for intruders to trick you (sometimes referred to as "social engineering") into installing "back door" programs. These can allow intruders easy access to your computer without your knowledge, change your...

...Abstract Now that personal computers are pretty much a must have in every household, school, or business cyber-criminals have moved from just being a hacker for fun into an estimated multi-million dollar world of computer crimes. New revenue streams have been realized and viruses in choice Computer crimes encompass unauthorized or illegal activities perpetrated via computer as well as the theft of computers and other technological hardware. As firms of all sizes, industrial orientation, and geographic location increasingly rely on computers to operate, concerns about computer crime have also risen, in part because the practice appears to be thriving despite the concerted efforts of both the law enforcement and business communities to stop it. But computer experts and business consultants alike note that both international corporations and modest family-owned businesses can do a great deal to neutralize computer "viruses" and other manifestations of computer crime. “http://rahimimohammad.blogspot.com/p/law-for-computer-crimesand-economic.html” Many analysts believe, however, that small business owners are less likely to take steps to address the threat of computer crime than are larger firms. Indeed, many small businesses admit that they are passive about the threat because of costs associated with implementing safeguards and the perception that computer "hackers" and other threats are far more likely to pick on bigger companies. But as Tim McCollum flatly stated in Nation's Business...

...Individual: Network Based Threat Research There are so many people who are connected to network and with the passing time, the amount of people connected through network is increasing even more. As the network connectivity is increasing, the threats to security are also increasing. Network security and network-based threats are the most significant vulnerabilities that need to be maintained as it involves information, which is transferred between computers. There are several pieces of information, which is case sensitive and is vulnerable to outside attack. The network security is also exposed to hackers attack and is subject to various malicious threats that can endanger the sensitivity of information and pose a threat to network. The various network-based threats are pumped into the network all over the world and are a significant matter for consideration at the moment (Godbole, 2008). Network based threats There are various network-based threats some of which are explained below: * Viruses and Worms: Virus is a coded program or coded information that is transmitted or loaded into the computer unintentionally and run on the system. It exploits the system without the knowledge and wish of the system owner and can create huge damage and harm to the computer.

...IT for Decision Makers NETWORKING AND SECURITY ISSUES Handout 1 Overview Introduction Many organizations have invested vast amount of money in computer networks, only to find out that although it is providing means of improving the efficiency and productivity of the organization but it also exposes the Organization to possible attacks and threats. Such attacks have been the most challenging issue for most network administrators and a worrying topic for administrators. Organizations need to share services resources and information but they still need to protect these from people who should not have access to them, while at the same time making those resources available to authorized users. Effective security achieves these goals. The greatest threat to computer systems and their information comes from humans, through actions that are either malicious or ignorant. When the action is malicious, some motivation or goal is generally behind the attack. For instance, the goal could be to disrupt normal business operations, thereby denying data availability and production. April 13, 2000, 3:55 P.M.

...Security Threats And Attacks Week 4 Case Study Dustin Soria Security Threats And Attacks Week 4 Case Study Dustin Soria 2014 2014 Recent statistics show that a large percentage of people have the idea that computer security is an issue that only affects organizations. Many people believe that, at a personal level, there is little that one can have to do with their information especially because they don’t see if someone will need their information. In contrast, there is a lot of useful information that a third party may obtain from a personal computer that the user may not even realize. For instance, a user may have sensitive information that would lead to his or her private life, secrets, or even important financial information. Such information can be used by attackers to monitor their internet activities, whether they are logged into their own personal computer on a local network, or even the internet. The victim’s sensitive information can be sold over the internet, or even to third parties such as advertisers and criminals among others. As such, it is important that serious security measures are taken to protect one’s personal computer from such security issues. There are numerous security threats that can be on a personal computer. One of the most common threats is a Virus. A Virus is a piece of software that can replicate itself and infect a computer without the permission or knowledge of the user. A Virus can only spread when it is transmitted by a user...

...Mobile Device Security and Other Threats Melissa M Dr. Constance Blanson Theories of Security Management November 30, 2014 Analyze the emerging security threats presented within the “Security Threat Report 2014” Security threats have not only grown and matured quickly, but the people behind these threats have become more creative in camouflaging their work. These criminals have become more adept at eluding their identification and are now relying on cryptography. Malware authors, as with users, are now focusing on mobile devices and web services. Numerous threats were listed in the Security Threat Report 2014 such as botnets, android malware, attacks on Linux platforms and Mac OS X, web-based malware, targeted threats to your financial accounts, unpatched windows systems and re-invented spam. These items are detrimental to companies and users. The more complex these threats get, the harder it is to protect against them. I will analyze botnets and android malware in this section. A botnet is a network of private computers infected with malicious software and controlled as a group without the owner’s knowledge. Criminals distribute malicious software that can turn your computer into a “bot”. When this occurs, your computer can perform automated tasked over the Internet without your knowledge. This type of malware is typically used to infect large numbers of computers. They are used to send out spam email messages, spread viruses, attack computers and servers,...

...Cyber Security Student: Maurice Jones Class ISSC461: IT Security: Countermeasures Instructor: Professor Christopher Weppler Date: 2 August 2013 Introduction “In a future conflict, an adversary unable to match our military supremacy on the battlefield might seek to exploit our computer vulnerabilities here at home (President Barack Obama, 2012).” Technology has changed the total lifestyle of people around the world. Here in the United Stated, society’s daily lives revolve around social interaction, economic stability, job security and information dominance. Information Dominance is “the degree of information superiority that allows the possessor to use information systems and capabilities to achieve an operational advantage in a conflict or to control the situation in operations other than war while denying those capabilities to the adversary (US Cyber Command, 2012).” Corporations as well as many of the world’s governments have risen and fallen due to their degree of Information Dominance and Information Security. Cyber-attacks have increased exponentially within the last 10 years. Battlefield lines that were once drawn in the sand no longer exist. Cyber-attacks can occur from any location in the world and at any time. A Cyber-terrorist has the ability to use current communication infrastructure to launch an attack that could cripple a nation. In 2012, Defense Secretary, Leon Panetta spoke at the Business Executives for National Security (BENS) summit....
