...May 31, 2011 Robert Markovic Attack Prevention The following paper will try to answer and explain the importance of protection and address antivirus software’s that prevents viruses from attacking personal and corporation computers. Protecting personal and corporate computer at home or office is very important. It comes to the IT community that no matter how hard a client tries or do viruses will intrude his or her network one day. The importance of virus prevention is to save data and hardware. The software companies give clients tools and directions on how to prevent virus from attacking computers. Antivirus software can prevent some but not all viruses from attacking. The article states “It is a sort of “sleuth and burglar” game being played by antivirus and virus producers. The most and ever updated antivirus, shields you against all defined threats till that time. You can subscribe to auto update feature which works for you behind the screens giving the best possible protection when you go online” (Secureurpc, 2010). This protection software advises the client about suspicious files. When a client cannot catch or kill a worm know as a virus, this software will allow the client to quarantine and run a full scan of the network. Spyware prevention and pop up blockers helps in preventing viruses on a network. As soon as a client connects to the Internet spyware is the automated software that launches and display a report back to the client with any information leading...

FIREWALL: Because the internet is a public network, any connected computer can find and connect to any other connected computer. A firewall is a barrier between the internet and your own computer or network. A firewall protects you against: * Hackers breaking into your computer. * Worms – types of viruses that spread from computer to computer over the internet. * Some outgoing traffic originating from a virus infection. Solution: Check if your Windows Firewall is switched on. 2. Viruses and Spyware: A virus is a file written with the sole intention of doing harm, or for criminal activity. There are many types of virus. The Risks Viruses and spyware can attack your computer via the following means: * Opening infected email attachments such as .exe files. * Opening infected files from web-based digital file delivery companies (for example YouSendIt, Dropbox). ...

...Viruses can also replicate themselves. The main ones are Trojan horse, Spyware, adware and worms. Trojan horse is a program written to deliver a malicious program that may then cause destruction to your computer. A Trojan horse is delivered by someone or hidden within another program that may seem harmless. Spyware is a program written to monitor your actions on a computer. A common type of spyware is a key-logger program. This program can record every key stroke and mouse click you make. Spyware can be delivered via a Trojan horse program. Some spyware is not meant to be malicious, such as tracking cookies. Adware is a form of malware. One word - pop-ups. Adware is designed to pop up advertisements. Adware can be very annoying.

...to a system. It’s up to the personnel or team that’s in charge of protecting the system from threats and vulnerabilities. The personnel that secure information technology systems are known as (ISO) Information Security Officer, (IASO) Information Assurance Security Officer, (ISM) Information Security Manager ect. No matter what name the personnel there job is the same to protect information systems. Security Officers will have to set policies that govern the system and create plan on how to handle security threat and vulnerabilities. Security threats can consist of any number issues ranging from physical attack, spoofing, password attacks, identity theft, virus attacks, and Denial of Service attacks, Social Threats, Espionage, malware, spyware, Careless Employees, and hackers. We will disuse all of these threats and ways to prevent them later in the report. In 2010 Kevin Prince, CTO, Perimeter E-Security "As these security threats are becoming more serious and difficult to detect, it is vital for companies to understand what they can do to best protect their systems and information” he also was implying that Information Security Office stay update with changes in Information Technology community.

...be mentioned in the acceptable use policy (AUP) to insure users understands the importance of Richman Investments classifications. Documents with the Internal Use Only classification should be handled with care and protected by everybody within Richman Investments. There are many different ways for sensitive information to be leaked but we will be focusing on these three: The User Domain, The Workstation Domain, and the LAN Domain. The User Domain is the weakest link but one of most important and it’s one that everyone has a hand in. When going through the AUP the user must sign and agree to the terms. This will give Richman Investments the leverage to make decision based on the employees conduct. We must insure we hire good trustworthy candidates for the job that will not violate the policies set before them. Word of mouth is another way that information leaks to outside agencies. Users should not be allowed to bring in their own media data without signed approval from the IT department. The users should also be limited access to the sensitive information based on their job descriptions. Workstation Domain is a part of the protection that needs to be kept up to date and mentioned in the AUP. Allowing a computer without the most current updates and patches could be a harmful. New threats have come along and need the newest updates to keep from allowing Viruses, Malware, or Spyware from getting into our Internal Use Only documents. Leaving your desk with your...

...The relatively new job sector made available through accounting and the Internet has come to existence with the assistance of E-accounting. The first electronic spreadsheet was designed in developed in 1979, following the creation of the first successful PC created by Steve Jobs and Steve Wozinak. Bob Frankston and Dan Brinklin developed the first electronic spreadsheet for the Apple II created by Steve Jobs and named the spreadsheet program, “VisiCalc”. The creation of VisiCalc turned out to be one of the most important business applications for the PC. Prior to its inception in 1979 all accounting was done primarily by hand or with the use of very complicated and massive computing devices. It was not until the invention of the PC did the public at large and independent accounting professionals have access to accounting technology on the Internet. Electronic accounting began with the use of spreadsheets. Spreadsheets allowed accountants to translate the manual functions of the general ledger into a computerized accounting system. Software companies would eventually create software programs to focus on accounting, based on traditional accounting processes. E accounting is the use of online accounting applications and Internet technologies to support the business accounting function. E-accounting involves performing regular accounting functions, accounting research and the accounting training and education through various computer and internet based accounting tools such as: digital...

...1. What is the responsibility of computer owners to keep their systems secure from the attack of bot herders? A computer owner’s responsibility to secure their system from the attack of bot herders is to always keep the operating system and applications current to the most recent release. This is because; all software is subject to a constant revision process as new security vulnerabilities are found and patches to correct any problems. Keeping antivirus up to date is also important. 2. Is a computer owner who refuses to purchase or use software and hardware to block attackers complicit when a bot herders attack, captures and then uses an unprotected computer to commit a crime? I think the computer owners should also be held responsible if any bot herder use the owner’s computer for criminal purposes. The owner should provide effective firewalls and other safeguards to their computer. 3. Do software developers shoulder some of the blame when they distribute operating systems and applications that include security flaws that make computers vulnerable? I don’t think so. Becacuse for me, nobody is perfect. Anyone is entitled for any lapses he or she may execute but that does not mean there will be no room for correction. If further development is needed, then it should be done in order to eliminate these bot herders who kept on seeking cybercrimes. 5.16 What are two tactics criminals use to commit credit fraud? What are two countermeasures financial institutions...

...systems are exposed to numerous kinds of malware threats. The goal of malware is to enter the computer system in a hidden way. The main purpose of malware is achieving monetary gain at the expense of the victims. There are a few categories of malware: Adware, Bot, Bug, Ransomware, Rootkit, Spyware, Trojan Horse, Virus, and Worm. Each one of these types of malware has a specific function and effect on the end user’s computer system. Adware is an application that usually comes bundled with an application downloaded from the internet, in which it monitors the internet activity and provides advertisement according to the internet browsing behaviors. Bots are programs designed to run automated tasks. Bots gain popularity in being used on systems to run DDoS attacks. Bugs are flaws within the applications that an attacker can take advantage to exploit the computer system. Ransomware is an application that infects the computer system and encrypts files and holds the system hostage until the end user pays a fee for the unlocking mechanism. Rootkit is a malicious piece of software that is very stealth and allows the attacker to collect all kinds of information from the system and even remote control it. Spyware is related to Adware in which spies on the user’s activity without their knowledge and collects data such as keystrokes, logins, monitoring internet activity, etc. Trojan Horse is an application that disguises itself as something safe and known to the user and in reality contains a malicious...

...malware based on the suspected intentions of the designer rather than any particular features the software may or may not have. Malware, also known as computer containment, has grown to include computer viruses, worms, Trojan horses, spyware, dishonest adware, crimeware, and other malicious and unwanted software programs. Symantec published in 2008 that “the release rate of malicious codes and other unwanted programs may be exceeding that of legitimate software applications”. According to F-Secure, “As much malware was produced during 2007 as in the previous 20 years altogether.” Malware has become the most common pathway on the Internet for criminals to access users: especially through e-mail and the World Wide Web. The frequency of malware use for organized Internet crime, along with the inability of anti-malware protection products to protect against the incessant stream of newly produced malware, has encouraged a new mind-frame for business owners who operate on the Internet. Business owners acknowledge that a large percent of Internet customers will always be infected for one reason or another, and they need to continue doing business with customers whose systems are infected. The result of this information has yielded an importance on back-office systems that are intended to spot deceptive activities that are normally seen with advanced malware operating on customer computers. Malware is not the same thing as legitimate software that is considered defective or contains...

...Networks, Telecommunications, and Wireless Computing | | | Telecommunication systems enable the transmission of data over public or private networks. A network is a communications, data exchange, and resource-sharing system created by linking two or more computers and establishing standards, or protocols, so that they can work together. Telecommunication systems and networks are traditionally complicated and historically ineffi cient. However, businesses can benefi t from today’s modern network infrastructures that provide reliable global reach to employees and customers. Businesses around the world are moving to network infrastructure solutions that allow greater choice in how they go to market—solutions with global reach. These alternatives include wireless, voice-over internet protocol (VoIP), and radio-frequency identification (RFID). | | | | | Knowledge Areas | Business Dilemma | | | Business Dilemma Personal sensing devices are becoming more commonplace in everyday life. Unfortunately, radio transmissions from these devices can create unexpected privacy concerns if not carefully designed. We demonstrate these issues with a widely-available commercial product, the Nike+iPod Sport Kit, which contains a sensor that users put in one of their shoes and a receiver that users attach to their iPod Nanos. Students and researchers from the University of Washington found out that the transmitter in a sneaker can be read up to 60 feet away. Through the use of a prototype...

...Importance of Firewall The importance of a firewall is that it blocks malware that would be able to scan your computer to find its vulnerable areas and then attempt to break it while it is at its weakest point. First of all there is only one way to make your computer completely safe from attack and that is either when it is off or unconnected from the Internet. Other than that there are always vulnerabilities. However, you can make it as close to hacker proof as possible while it is connected to the Internet. The way to do this is to have a personal firewall installed along with antivirus and anti spyware protection. Plus you have to make sure that all three of these are updated on the regular. Additional protection is available to a network that used a router with a firewall feature. Firewalls protect your computer from outside attacks by guarding it from unnecessary Internet traffic. They can however be configured to block certain data while letting other data in. The importance of a firewall on your computer can not be underestimated especially for those who are always connected to the Internet. Firewalls are positioned between your computer and your network and are great for protecting multiple computers but also offer a great degree of protection for single computer use. It allows individual users decide how much content they want to filter through and what websites are safe to use. In some cases users have a very lax opinion of what should and should not be allowed...

...The Importance for Cyber Security BCOM/275 Cyber security is an essential element to any business and our Government. Unfortunately many corporations do not realize the importance of computer security until it is too late and have experienced a cyber-attack. The consequences of such an attack can be quite severe, as businesses carry an obligation to everyone involved to protect their identity and personal information. Today we are more reliant on computers and to the networks related to them more than ever, because of this reliance, security has become priority number one. Cyber security is an essential factor to be measured in order to defend ourselves and livelihood from hackers and dangerous software designed by people with ill intent. The majority of these dangers to computer networks come from the internet and these are frequently intended to have terrorist like effect on networks and most importantly, people’s lives. Recent attacks have been very high profile, including the Sony hack which is still being investigated. Cyber security is, therefore, by definition an attempt by an individual or entity to protect their personal information and data from cyber-attack. Cyber security involves multiple steps, the most significant of these being an individual’s understanding of the diversity of these cyber-attacks. Once one has knowledge of this, then it is the individual’s responsibility to make sure they have reliable and up to date software...
