Cellular Debate





Network Security Issues on Cellular Network One major advantage of Cellular network security is the ability of communication to be done “Wirelessly” (Xiao et al, 2007). This means that the signals do not follow a specific assigned signal path which may be destroyed by vandals or even by nature, as in case of copper conductors or other physical media such as fiber optic. In addition, data security is enhanced by used of packed switched data in which data is send in form of packets and at no particular order only to be reconstructed at the receiver which makes intercepting such messages cumbersome. In addition, user authentication allows only specific users registered to a specific cellular service provider to use their resources thus allow proper billing to be charged according to the usage of the network(Xiao et al, 2007). A security issue that arises from the use of the cellular networks is subscriber authentication. These systems consist of a large number of subscribers who need to be identified and verified before they can enjoy the services offered by the provider. If authentication is not properly done, then the network is vulnerable to misuse by subscribers not entitled to use the network leading to the service provider incurring losses. Confidentiality is another security issue that can be noted in cellular network (Ciampa, 2009). This is because the ‘air’ channel can be intercepted by malicious people and redirect signals to unintended recipients or even distorting the information signal lowering its credibility. This is method in which an attacker intercepts communication messages by sitting in between the access station and cell phone and changing them is referred to as Man in the Middle Attack (Ciampa, 2009). Privacy to the network user is a critical security issue that affects cellular…...

...Network security Network Security Installing firewall or anti-virus software on enterprise workstations can help prevent some of the security problems the Internet can cause; but not everything. By understanding the different Open Systems Interconnect (OSI) levels and security threats involved with each one of them, it is easier to plan a strategy to combat security problems. Purpose and Scope To cover all areas I have listed the network security measures that are associated with each level of the Open Systems Interconnect (OSI). Physical layer This layer is responsible for moving raw bits from one node to another: electrical impulse, light or radio signals. This layer represents the physical application security. It includes access control, power, fire, water, and backups. Many of the threats to security at the Physical layer cause a Denial of Service (DoS) of the enterprise application, making the application unavailable to enterprise users. To ensure this does not occur, the electrical and mechanical parts of the network are not only tested periodically but are kept safe from external damages like tampering or other physical destruction. The backups are in a secured room only few people have access to this room. One method used to manage security in this layer is through Physical Layer Automation. By use of tools such as the Apcon's IntellaPatch™ line of copper and fiber Physical Layer switches, the network administrators have control and security at the......

...Case Study: Network Security Computer networks of every company have the potential to be exposed to dangers that have the potential to do great harm. Individuals could gain access to Windows and Unix/Linux servers to exploit the company’s vulnerabilities. Computer networks are not only vulnerable to outsiders, but employees also have the opportunity to compromise the system. An unprotected network would open the door for malicious activity that could damage the company’s system, compromise company and customer information, and cost a great amount of precious time and money. A breach in the network could have a negative impact on finances, privacy, and information. Securing the Windows and Unix/Linux servers within a company from shortcomings and vulnerabilities to potential threats by both outsiders and insiders is an absolute necessity. This is achieved by using technical measures and enforcing security policies. One reason it is important to secure the servers is potential of the insider threat. With 1,500 employees, the chance of an attack from the inside is elevated. The threat could come in the form of a disgruntled employee, by someone looking for gain, or by someone who unknowingly compromises the system. Conklin and White (2010) stated the following: One of the hardest threats that security professionals will have to address is that of the insider. Since employees already have access to the organization and its assets, additional mechanisms need to be in place to......

...Network Security When it comes to networking and the security of networks, there are several different methods of protecting networks. Of these differing methods, some of them sound similar, but provide differing levels of security. In the following paragraphs, I will try to explain the differences between some of the methods used. • Explain the difference between historical and statistical logging. Logging is a simple way of keeping a record of activity on a network. There are several types of logs that can be kept, each providing different data that can be analyzed to provide information on potential ways of improving security over time. With historical logging, records are kept of all data passing through a particular network device. This might be the gateway separating a network from the outside world or an internal router on the network. In either case, the record kept can then be analyzed at a later date and hopefully provide insight on the security of the network. Statistical logging is a more efficient form of logging and includes some analysis already built into the report. This information might include which users were logged in during which time frames, what files were accessed, and how long they were logged in. By watching for different trends in this type of report, potentially harmful activity is more easily identifiable and mitigated. • Explain the difference between file security and firewalls. Firewalls provide a barrier between internal networks...

...Network security is the process of protecting the user from things that can potentially ruin a computer or leak information that other people should not have access to.Some things that can attack a network system include viruses,worms, as well as trojan horses, spyware along with adware,attacks called zero hour,attacks by hackers,denied service hacks,data interception and theft,and the last on being identity theft.In order for network security to work it needs to have both hardware as well as software to protect the network which is done with things such as anti virus and spyware software.It also needs a firewall which is responsible for blocking the unauthorized user from gaining access to the network.Intrusion prevention systems which are tasked with identifying attacks such as zero hour.The last thing to make network security work is a virtual local area network which provides secure remote access. By using these various methods of protecting the network it will benefit the businesses by receiving the customers trust in the company by making sure their privacy is protected in such ways as making sure things like credit card data or sensitive data is stolen and exploited.It also makes sure the network is secure even if it is being used by someone remotely as long as ......

...Network Security Clint Tipps September 21, 2014 ISSC340/ APUS Prof. Bryan Jensen Abstract This paper will cover several aspects of network security. Numerous different aspects of wired and wireless network security, including protocols applied to secure a network, penetration testing, digital forensics, and network hardening will be covered. There are numerous methods for providing security to a network, and even more to gain access to one. The challenge is to be one step ahead of anyone who may wish to penetrate the network. For this reason, many owners of large networks perform penetration testing in order to identify potential holes in their network. If malicious activity is detected, using digital forensics can help identify where the attack came from. This would, in turn, lead to a network engineer to harden the network against the identified threat. Network Security Over the last decade, computer systems have increased in speed and capacity while decreasing in price. Computers that where once used in corporate environments are now less powerful than a typical household computer. While this sea change occurred, network communications have grown and improved, to allow computers to communicate easily from remote locations, adding vast opportunities for illegal activities. Data can maliciously be changed or destroyed, systems can be made to malfunction and long distance charges can be avoided. One of the biggest challenges today is to control the security of......

...Network Security Network Security The field of network security is a very dynamic, and highly technical field dealing with all aspects of scanning, hacking and securing systems against intrusions. There are many positions related to this, however the most common would be that of a Network Security Engineer, a Security Research Analyst, a Penetration tester, and an Incident Investigator. All four of these jobs have salaries starting in the forty to fifty thousand annually range, and can grow well past the one-hundred thousand mark, depending on skill and experience. A Network Security Engineer is responsible for end-user support for general security related issues, as well as enforcement of the local security policy. They are also typically responsible for performing ongoing security scans to ensure that the System Administrators are keeping their systems up-to-date and secure. A Security Research Analyst is someone who performs research in the field of network security to devise new weaknesses and vulnerabilities, as well as new methods of intercepting and preventing system compromises. They will also typically develop applications to employ the data they have gathered. Another position, the Penetration Tester, is someone who scans networks and/or hosts for vulnerabilities, and then reports on these vulnerabilities to show how they could break into a computer system or network. This information helps the Network Security Engineers to keep their systems secured. The last......

Wireless Networks & Network Security

...Wireless Networks & Network Security ISSC 340 Professor Vijay Venkatesh James Lange 08/13/2013 Wireless Networks are somewhat new technology in comparison to the know-how that makes them possible. The knowledge regarding wireless technology goes back about 200 years. One of the first individuals deserving recognition for today’s wireless networks is a scientist, inventor and politician named Benjamin Franklin. In 1747 he had built a model that showed how electricity could move through the air unaided by any type of wiring. In the early 1750’s Mr. Franklin started experimenting with electricity and the rest is history. Franklin was under the belief that lightening was an electrical current. So with the famous kite and key experiment he proved to himself and others that he was right. His fascination with electricity led him to later experiments with an electrical tube given to him by a friend. A second individual that played a part in today’s wireless technology is Hans Christian Oersted. In 1819 he had found that a compass needle had movement if it was presented with electrical current. This relationship between the needle and the electricity is an essential part of electromagnetism. It is said that this discovery by Oersted happened completely by chance. While preparing for one of his lectures he was setting up some of his equipment. The compass and battery were in close proximity to each other and the needle moved from magnetic north whenever the switch to......

...Introduction: Network security is a complicated subject, historically only tackled by well-trained and experienced experts. Initial period of computing, when secured mainframes acted as central hosts and data repositories were accessed only by dumb terminal with limited rights, network security was all but irrefutable. As networks have become geographically more distributed and heterogeneous, however, the risk of their misuse has also increased. As more and more people become “wired”, a large number of people need to understand the basics of security in a networked world. Moreover, Network security is one of the most important part of the computer technology now a days. So now people are more aware about this kind of threat than ever before. They are learning about how to compute the security of a network and fix the common issues in order to have a secure network and trusted internet connection. These are few of the things that you should know very well before you deal with network system because it is save you a big pain later if you don’t know how to use. Some of the things that you can implement are the security principles, mange the security network, how to detect the intrusion in the system, windows and web security and also the most important; police security of network. The best way to prevent intrusion on a network is to read all the policies that show up several times on the system.

...Nasario Birrueta IT 200: Milestone Three Network Security Network security is one of the most important aspects of implementing a fully functional working network, downtime caused by poor network security can cause major economic loses. The two matters that need to be addressed is the User and Physical equipment. Network security begins with the user. As such would implement a Network Use policy that the employee must sign and adhere to. The company network is to be used for work purposes only. All activity will be monitored and subjected to review by upper management. All users will use strong passwords that are at least 8 characters with upper case and at least one number and not to be shared not even to their immediate supervisors unless OK by IT and or upper management such as a VP or higher. All passwords will be monitored and subject to a monthly review and a password change. Users who do not need internet access will not have access to the internet, a warehouse employee would not need internet access to complete his job duties. But a purchasing employee would need to research for supply vendors that employee would need internet access. In a scenario where a warehouse employee needs internet access a password could be utilized that opens the internet for such these are often called Proxy server or a service that could be used is OpenDNS. At the network level all Personal computers will have the latest and greatest anti-virus software along with all...

...Network Security Abstract: To begin to understand network security it is best to look at the basic definitions. A network is defined as “a group of two or more computers linked together”. An attack is defined as “an aggressive and violent act against a person or place”. Lastly, security is defined as “the state of being free from danger or threat”. Since the beginning of networking there have been users out there with malicious intent to either gain information or disrupt it. Technicians may not be able to stop the initiation of attack but there are certainly tools and techniques to fight back. This paper will discuss the protocol layers of networking, the associated threats and applicable solutions. This research paper will include an analysis of networking and examples of attacks. While not all solutions will be touched upon, this paper will give you a basic understanding of the way forward. Many references sited in my research are scholarly, peer reviewed journals and are considered experts in their field of Information Technology Technology is the basis of many operations in society today. While technological advances have made numerous processes easier and faster, it has also introduced an equal number of negative practices. This paper will discuss the theoretical model of networking which breaks up the data transmission process into multiple layers. We will first take a look at the original networking model and its functions compared to the newer model. Next we......

...this exploitation, companies subject themselves to lawsuits from their own customers. These companies often are ignorant of the simple fact that they have been exploited until customers report the issues to these companies and corporations. Many times, more than thirty days goes by before someone alerts the company of a possible security breech. Cost of an electronic exploit can be greater than a million dollars per incident as reported by the FBI. This information is found in the FBI’s (Federal Bureau of Investigation) report of cyber threats in the United States. In order to help counterbalance this, smaller to midsized companies could spend less than $5,000 to harden their systems and operating systems to put a statefull firewall in place. As stated in this paper, these companies often lack the resources, materials and funds to do so. With the FBI report showing reported incidents, there are thousands of incidents that go unreported. Often these incidents are yet to be discovered. With this number of small to mid-size corporations ignoring or slowly implementing security measures, more and more electronic computer crimes are beginning to take place throughout the U.S. With extortion now moving into the digital age, many corporations do not report intrusions to law enforcement in order to avoid negative publicity. Reports of an intrusion could directly have a negative effect on the company’s sales and position in a global competitive market. Approximately 35%......

...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......

...Importance of Security The Internet has undoubtedly become the largest public data network, enabling and facilitating both personal and business communications worldwide. The volume of traffic moving over the Internet, as well as corporate networks, is expanding exponentially every day. More and more communication is taking place via e-mail; mobile workers, telecommuters, and branch offices are using the Internet to remotely connect to their corporate networks; and commercial transactions completed over the Internet, via the World Wide Web, now account for large portions of corporate revenue. While the Internet has transformed and greatly improved the way we do business, this vast network and its associated technologies have opened the door to an increasing number of security threats from which corporations must protect themselves. Although network attacks are presumably more serious when they are inflicted upon businesses that store sensitive data, such as personal medical or financial records, the consequences of attacks on any entity range from mildly inconvenient to completely debilitating—important data can be lost, privacy can be violated, and several hours, or even days, of network downtime can ensue. Despite the costly risks of potential security breaches, the Internet can be one of the safest means by which to conduct business. For example, giving credit card information to a telemarketer over the phone or a waiter in a restaurant can be more risky than submitting......
