...Individual Final Project NTC/362 Fundamentals of Networking Dean McIntyre 2 The Patton-Fuller Community Hospital looks to upgrade their Information Technology (IT) capability beginning with their networks. The characteristics, components, and topology are evaluated to properly identify the needs for the new network design. The plan includes converting to a Wireless Local Area Network otherwise known as (WLAN), installing a Voice over Internet Protocol otherwise known as (VoIP), and design a Wide Area Network (WAN). The plan also includes the hospital maintaining all Macintosh® computers. Administration/Clinical Overview * The administrative departments run off of a 1000 Base-T Ethernet provided by a CAT 6 cable which is also the entire hospital’s network backbone. Clinical department networks however are provided by a 1000 Base-F Ethernet provided by a single mode fiber. The clinics feed into a Cisco Catalyste 3560 Switch as the network bridge that links the two together. All workstations are Apple iMAC or MAC Pros with the executive management, senior managers, and the data center workstations as having a wireless communication card installed. * IT Data Center * The data center is comprised of the hospital HIS system. The mainframe of the HIS is connected by a 4 gigabit fiber link to a 10 terabyte Network Area Storage (NAS) device. The data center’s workstations are all Apple iMACs that run a MAC OS X from a remote desktop. Virtualization...

...Student’s Name Case Study 1: Florida Department of Management Services, Part 1 CIS 505 Communication Technologies Professor’s name May 5, 2013 Analyze the security mechanisms needed to protect the DMS systems from both state employees and users accessing over the internet: Department of Management Services (DMS) has chosen to expand their applications and services via TCP/IP and Internet access. DMS uses a widely used proprietary scheme: IBM’s Systems Network Architecture (SNA) which provides support for TCP/IP (Transmission Control Protocol/Internet Protocol). SNA architecture is projected to remain important for some years to come. Implementing standardized protocol architectures allow DMS ongoing communication with suppliers, vendors, customers, and employees across the state, thereby improving overall productivity. Two protocols architectures have served as the basis for the development of interoperable protocol standards: the TCP/IP protocol suite and the OSI (Open Systems Interconnection) reference model which organizes the communication task in relatively five independent layers: Application layer, Host–to-host, or transport layer, Internet layer, Network access layer, and physical layer as each layer provides a portion of the total communications function required for distributed applications. (Stallings, 2009). Furthermore, TCP/IP operates in a packet-switched format as it seeks to transmit in the most efficient manner at high rates of speed. The packet-switching...

...Cryptographic Tunneling and OSI Model Data Security means protecting a database from destructive forces and the unwanted actions of unauthorized users. (Summer, 2004) With the explosion of the World Wide Web and the need to connect various secure private networks to it, it is vital to protect private data from exploitation when it reaches the public networks for transmission. At the heart of the networks through which the information flows is the Open Systems Interconnection (OSI) model. Various techniques are used with respect to the OSI model that helps the data to be transmitted more securely during network transmissions. One of these techniques is Cryptographic tunneling. Cryptographic tunneling operates at the transport layer and network layer of the OSI model. Cryptographic tunneling is primarily used in VPNs or the Virtual Private Networks to add additional security to the data that is flowing through these networks. A VPN is a service that offers secure, reliable connectivity over a shared public network infrastructure such as the Internet. (Mason, 2002) The sender’s authentication, confidentiality of data and hiding the contents of the message is made possible using cryptographic tunneling. When we need data from private businesses to be transmitted through public networks, we make use of tunneling where the public network routing nodes are unaware of the transmission being part of private network. Hiding the packets to make them seem as if they were just like...

...Unit 2 Assignment 2 Vulnerability of a Cryptosystem What this vulnerability is doing is creating a rogue CA certificate, creating an MD5 collision on your next work. According to Microsoft this threat is not a major issue will no reports of this attack being used. Form the rewind that I have doesn’t I did not see any tools that were used to create this attack. I thin g that the system that they currently have still can be used by making some changes. N the system cannot be changed easily based on the size of the infrastructure. The exploit has not been released due to the fact that there are no reports of this attach being used. The likely hood of this being used is very small. I do not think that attacks would be conducted and the results would be crashing of sites and resources. This system is widely used for the University, and if it would become attacked the system its self would still be trustworthy you just need to change the algorithm to SHA-1. The information for eh technical audience is what is conveyed via the links. They need to know about the issues and be informed in order to determine if the change from MD5 to SHA-1 needs to be made. The nontechnical audience doesn’t really need to know anything about this attack. If the university is making the change the impacts will be very minimal and not affect them. If you are talking to management all you need to say is that you found a vulnerability and it can be taken care of with very minimal...

...Question 1 Shill Bidding Shill bidding is the act of bidding on your own auction - including family members, roommates, friends and employees - against other bidders in order to raise the price at which your item will eventually sell and is a violation of both eBay rules and federal law. Shill bidding is considered to be unfair to buyers because of deliberate placing of bids by fraud bidders to increase the value of the auctioned item. It is a major threat to the eLite Bankers Limited as it compels bidders to bid higher for the item. Phishing Phishing is a type internet fraud that seeks to acquire a user’s credentials – passwords, credit card numbers, banks account details and other credential information – by deception. They usually take the form of fake notifications from banks, providers, e-pay systems and other organizations to encourage a recipient to urgently update or enter their personal data. This is a major concern for eLite Bankers Limited as banks and other e-pay systems are major targets for phishers. This indicates that the fraudsters are more interested in personal data which provides access to money which can bankrupt a victim of phishing.

...Project Part 1: Multi-Layered Security Plan Loren Miller NT2580 Monday PM Introduction: Describe each layer of the Open System Interconnection (OSI) Model. List a security feature of each layer if it applies. List the protocol of each layer if it applies. List types of attacks that are you protecting against in each layer. Your goal is to be able to protect a web hosting company that has a global presence. This web hosting company supports customers in the following industries: Medical, Financial, and Governmental. Physical Layer: The Physical Layer defines the physical properties of the network, such as voltage levels, cable types, and interface pins (Baker). Any attack on the Physical Layer would have to be some type of physical action, like disrupting a power source, changing of interface pins, or cutting the actual cables. Simply tampering with someone’s fuse box outside their office can cause a disruption of service. Faulty power is a problem that can be caused accidentally by the power company, or intentionally by your competitor tampering with the fuse box. A smaller business may consider installing an Uninterrupted Power Supply (UPS) which may help avoid many unrecoverable power associated problems. The addition of a UPS to your critical system will give you time to perform an orderly shutdown when power is interrupted. An abrupt termination of power to any electrical equipment has potential for great damage. Much in the same way you might protect your home...

...protected against security threats that exploit vulnerabilities. Organizations must therefore impose appropriate controls to monitor for, deter and prevent security breaches. Three areas have been considered, in a typical sense, as the basic critical security requirements for data protection: confidentiality is used to assure privacy; principles of integrity assure systems are changed in accordance with authorized practices; and, availability is applied to maintain proper system functions to sustain service delivery (Dhillon, 2007, p. 19). These security requirements are represented in Figure 1, Classic Critical Security Requirements. This figure depicts the cross-domain solutions of informal controls, also known as human relationships, and formal and technical controls, which provide for organizational and physical information security controls, respectively. Two additional security requirements have recently been added that are of particular importance to networked environments because attacks now extend far beyond traditional firewall perimeters. These are authentication, which is used to assure a message actually comes from the source it claims to have originated; and, nonrepudiation, which can be applied to prevent an entity from denying performance of a particular action related to handling data, thereby assuring validity of content and origin. Figure 2, Core Data Security Set, depicts the interrelationship of the five core requirements of information security. The remainder...
