...taskings that are very dependent on a business network to achieve these tasks. Many businesses whether private, public, or federal rely solely on their computer networks to protect, store, and disseminate information within its internal networks among employees and to its external customers reaching out to provide important business information. How do businesses and organizations protect these networks from potential malicious activity that could interfere with their daily business needs? There are various methods of protecting these networks which will be examined in this paper on the advantages and disadvantages of protecting your networks and enhancing operational security in today’s business world. There are various ways for a business or an organization to protect their network that would include management controls, operational controls, and technical controls that are in place to ensure any network meets certain security requirements. Various security protection methods fall into these categories which will be examined in this paper. Reviewing audit logs can be time consuming but it is an effective process that cannot be overlooked when protecting your networks. Security-relevant events, which meet audit requirements, should be collected, processed, and stored by automated means. These events should be available for analysis that can be performed by using a combination of automated and manual techniques. Network operations security staff in conjunction with system...

...Computer Security Protecting Your Computer System Do’s and Don’ts Abstract This paper explores the computer security process of preventing and detecting unauthorized use of computers. I will also discuss: A. The prevention measures (do’s and don’ts) to help you stop unauthorized users (also known as “intruders”) from accessing any part of your computer system. B. Detections methods that help you to determine whether or not someone attempted to break into your system; a. If an attack was successful b. If so, what they may have done. Computer Security Protecting Your Computer System Do’s and Don’ts We use computers for everything from banking and investing to shopping and communicating with others through email or chat programs. Although you may not consider your communications “top secret,” you probably do not want strangers reading your email, using your computer to attack other systems, sending forged emails from your computer, or examining personal information stored on your computer (such as financial statements). Intruders (also referred to as hackers, attackers, or crackers) may not care about your identity. Often they want to gain control of your computer so they can use it to launch attacks on other computer systems. Once an intruder takes control of your computer, they have the ability to hide their true location as they launch attacks, often against high-profile computer systems such as government or financial systems. Even if you have...

You can go there can see how it is done. Just a few years ago, (25 Sep 07) there were some so-called experts saying that there was no need to secure your wireless system. In an article, David Ramel alleges that the importance of wireless security is overhyped, that it's now trivial to secure wireless nets and that IT pros have far more serious security concerns they should be addressing -- while home users have little to lose even in the remote chance someone tries to breach their network. (3) This person was obviously living in a sheltered environment because identity theft and credit card theft was out of control then. Now he is saying don’t worry about protecting your network and to just hold on to your wallet; basically. Either he was very innocent or totally clueless and is eating humble pie about now. Here are a few disadvantages. A limited spectrum, war driving, interfering signals can be generated by other devices in the office environment, for example printers, microwave ovens and other electromechanical devices. Wireless is a public frequency network therefore its interface is highly risky because anyone can pick up your signal. No matter how your cut it, wireless is easier, more convenient and is here to stay, so you must protect is. Preston Gralla of Computerworld wrote an article on “How...

...Network Security Network security is a serious matter. A network allows you to share you to share information and resources, but it also lets computer viruses, human intruders, or even disgruntled employees do far more damage they could on a single machine, imagine what would happened to a company if all is data vanish, then you would understand why network security is so important to a company. Network can be group into Local Area Network (LAN), Wide Area Networks, Internetwork (Internets) all these networks need security to prevent them from nonmalicous humans and malicious attackers, hackers who are after destroying people or causing harm to a company. However before we discuss network security it would be good if we start with having a little knowledge of what a network is. A “network” has been defined as “any set of interlinking lines resembling a net, a network of roads, an interconnected system, a network of alliances”. We can also define network as a collection of communication host. Having said a little about network we then try to know what computer security is all about. Computer security is the process of preventing and detecting unauthorized use of your computer. When we take about preventive measures it help you to stop unauthorized users from accessing any part of your computer system and detection helps you to determine whether or not someone attempted to break into your system. Network security can be defined “as the provision made in an underlying computer...

...fire protection, possibility of water damage and protecting from EMI. Fire protection is very important so that if the building were to catch on fire the coating on the cables would not melt or at least not melt as fast. It is also smart to know where fire extinguishers are in order to possibly prevent the fire from spreading if it is not too large. It is important to consider the possibility of water damage because you do not want your servers and equipment ruined by some water that never should have touched it. In this case it is a good idea to know where water pipes run in the building so that you do not risk placing a network closet underneath a bathroom. Or right night to a bathroom for that matter. The possibility of flooding and ruining server equipment, firewall equipment, and cables by a bursting pipe or overflowing flood is just not worth it. You also want to make sure there are sprinklers but maybe not directly over your servers so that there is a possibility of saving them should they be set off for any reason. Protecting from EMI is very important so that you do not have any breaks in signal or weakened signal experiences. Making sure that your cables run perpendicular to power cables is one way to prevent EMI interference. Another way to prevent EMI is to make sure that you have shielded twisted pair cables instead of unshielded twisted pair cables. There are many things to take into consideration when doing a network installation, these just happen to be three that...

...processing incompatibilities or damage to computer hardware. An intentional breach in computer security is known as a computer crime, which is slightly different from a cybercrime. A cybercrime is known as illegal acts based on the Internet and is one of the FBI's top priorities. There are several distinct categories for people that perpetrate cybercrimes, and they are: hacker, cracker, cyberterrorist, cyberextortionist, unethical employee, script kiddie and corporate spy. A hacker is defined as someone who accesses a computer or computer network unlawfully. They often claim that they do this to find leaks in the security of a network. The term cracker refers to someone intentionally accessing a computer or computer network with malice in mind. They access computers with the intention of destroying or stealing information. Both crackers and hackers are having advanced network skills. A cyberterrorist is someone who uses a computer network or the Internet to destroy computer systems for political reasons. It’s similar to a terrorist attack because it requires highly skilled individuals, millions of dollars to implement and years of planning. The term cyberextortionist is someone who uses email as an offensive force. They usually send a company a threatening email stating that they will release some confidential...

...Securing and Protecting Information Jane Doe CGMT/400 March 9, 2015 John Doe Securing and Protecting Information As the most important asset within the organization it is necessary to provide measures that can effectively protect data from loss and unauthorized intrusions. Information security involves authenticating users with a high level of protocol and promoting accountability within the information infrastructure. This approach may involve use of the organization assets, identification, authentication, authorization and the use of third party security systems or devices to protect data from unauthorized access. Security Authentication Process The security authentication process is the first step in information security and assurance. This process involves “binding a specific ID to a specific computer connection” (University of Phoenix, 2011) in order to authenticate access to the information system. During this process the user provides a user ID and password to the computer system or remote server to verify his or her identity. Authentication is accomplished when the system or server matches the user ID to a specific password and grants the user remote access to system resources. Identification The identification process is an access control element designed to match a user to a specific process. The identification process is performed the first time a user ID is issued to a specific user. User IDs have unique values and can...

...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 to the identity of the unwanted intruders...

Many experts expect the number and severity of cyber-attacks to increase over the next several years. The act of protecting internet, computer systems and their contents has come to be known as cyber security. Abroad and arguably somewhat fuzzy concept, cyber security can be a useful term but tends to defy precise definition. It usually refers to one or more of three things: * A set of activities and other measures intended to protect—from attack, disruption, or other threats—computers,...

...Computer security and Network Security is the means by which business and governments are protecting against computer intrusions and attack to prevent loss of data, information and provided services. Everything is now on computers, peoples whole lives are documented on computers. Big business and the government rely on technologies that use computers, whether it is used for storage, a medium between the customers and themselves or actual work. With all this information and data being stored, transferred and used it needs to be secured. A bank is open to the public; you would not have this bank unsecured would you? There would be security guards, cameras, and a vault. The same mentality to secure your data should be implied if you have a network that is connected to the Internet. You should have software, hardware, and/or personnel monitoring your networks operations and security. All computers and systems that connect to the internet or networks run off software of some type. People called hackers or crackers, manipulate programs, create worms, and viruses to make systems do thing there not supposed to, access places they aren’t allowed, and shutdown or hinder a system from working properly (Dasgupta). Then there are attacks, phishing attacks which come in the form of email that try to lead you to fraudulent sites, Denial-of-service attacks overload servers causing no one to get on or shuts them down. Then there are SQL injection attacks which are used in security vulnerable...

...involving networking security. Being someone who works in network security I will need to have an in-depth understanding of how a network works, where the weakest point in a network is potentially and how to respond to a threat to the network. Along with theses, I also need to know what form of security I can put in place to protect the network from attacks. To protect a network I first have to understand a network and the following is a brief description of a basic network. A basic network is 2 or more computers that are all connected to help their users work together. A network connects computers by means of cabling systems, specialized software, and devices that manage data. A network enables users to share files and resources as well as send messages electronically (e-mail) to each other. Now for me as a network security worker, the first step to protecting this basic type of network is having the right form of security software installed on the computers. This software needs to be constantly kept up with to ensure the maximum amount of security is being used. Unfortunately having just one layer of security is never enough because if this one layer goes down then your entire network is open to being damaged or hacked by an outside source. Different forms of “attacks” include viruses, spyware, adware, hackers, and denial of service (DOS) attacks. Most of these threats will come into contact with your network via the internet and tend to be the most common found in today...
