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 will take a look at vulnerabilities that are susceptible to attacks within each layer. Finally we will take a look at possible solutions to thwart malicious activity. Before we begin, let’s take a look at the original model and break down its meaning.
The Open Systems Interconnect (OSI) Model is a suite of protocols specifying the process of networking by splitting functions into a seven layer...

...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. You are downloading a best item, it doesn’t mean it is security risk free unless......

...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 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......

...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 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......

...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%......

Demand for new improved services has become intense causing enterprises to reinvent their infrastructures by erasing traditional network boundaries. The cyber security threat lurking outside those boundaries is causing security analyst to rethink their views on network security. As the BYOD (bring your own devices) and cloud computing trend becomes more commonplace, security by exclusion by attempting to maintain hard perimeters is no longer a viable option. As the number of network devices continues to increase, the number of vulnerabilities also increases as well. As more and more organizations continue to be overwhelmed by cyber attacks it will become evident that the current strategy of responding to attacks no longer works. To be affective analyst will have to change their strategy from a reactive to a proactive state.

She begins the article by citing two major players in this debate: the U.S. Military with its rules and legislation vs. NATO and its international law. According to O’Connell, the USA feels that the military should have primary responsibility over the internet since it has the largest number of technical experts and legal authorities with respect to cyberspace than anyone else in the world. Many in the international community would disagree with allowing the US military to police the internet. They raise the question: What legal rules would be used to guide the military in its supervision of the internet. They believe that using international law is the best way to govern cyberspace usage. (Johnson, 1996) Still others favor the US military’s Cold War strategy of deterrence as a way of patrolling the internet. These that......

...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......

...Phase 2 Discussion Board CSS200-14002B-02 Principles of Network Security Chris Balla May 28, 2014 For the scenario provided in our discussion board for this week, I have decided to go with a choke point firewall strategy. This type of firewall seems to be less expensive than the other types of systems. It forces all of the network traffic through a single pathway. It also controls authentication as well as user activity. No data can pass through the choke point without being checked. This type of firewall can provide a single point of contact between our network and the internet; thereby giving the company more control over the data which can be permitted in and out of the internal network. Multiple choke points may also have to be used as well. The drawback to this type of firewall is that the choke point has to be very difficult in order for a hacker to bypass. Routers as well as switches can also be used to monitor the pathway. This type would evaluate and authenticate the network data, which is what the organization wants. I also considered the least privilege type of firewall as well. This would cause more administrative work but would ensure that users would only have the access needed in order to perform their job duties. The best way to accomplish this would be to group all of the users based on their access level or job descriptions. Doing this would also cut down on the amount of administrators needed to control the system. ......

...1) Construct networks using different types of network devices HUB Hub is one of the basic icons of networking devices which works at physical layer and hence connect networking devices physically together. Hubs are fundamentally used in networks that use twisted pair cabling to connect devices. They are designed to transmit the packets to the other appended devices without altering any of the transmitted packets received. They act as pathways to direct electrical signals to travel along. They transmit the information regardless of the fact if data packet is destined for the device connected or not.   Switches Switches are the linkage points of an Ethernet network. Just as in hub, devices in switches are connected to them through twisted pair cabling. But the difference shows up in the manner both the devices; hub and a switch treat the data they receive. Hub works by sending the data to all the ports on the device whereas a switch transfers it only to that port which is connected to the destination device.  A switch does so by having an in-built learning of the MAC address of the devices connected to it. Since the transmission of data signals are well defined in a switch hence the network performance is consequently enhanced. Switches operate in full-duplex mode where devices can send and receive data from the switch at the simultaneously unlike in half-duplex mode. The transmission speed in switches is double than in Ethernet hub transferring a 20Mbps connection into...

...Cellular Debate Name Course Date Tutor 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......

...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 ......
