The various innovations and uses to which networks are being put are growing by the day and hence are becoming complex and invariably more difficult to manage by the day. Computers are found in every business such as banking, insurance, hospital, education, manufacturing, etc. The widespread use of these systems implies crime and insecurity on a global scale. In addition, the tremendous benefits brought about by Internet have also widened the scope of crime and insecurity at an alarming rate. Also, ICT has fast become a primary differentiator for institution/organization leaders as it offers effective and convenient means of interaction with each other across the globe. This upsurge in the population of organizations depending on ICT for business transaction has brought with it a growing number of security threats and attacks on poorly managed and secured networks primarily to steal personal data, particularly financial information and password...

...Riordan Manufacturing uses a Wide Area Network (WAN) that allow the three locations to be connected to the corporate headquarters in San Jose, California. Along with the Wide Area Network to connect the locations to the Corporate Headquarters of Riordan Manufacturing, each location has its own Local Area Network (LAN). Network Architecture. The topology of the networks varies from site to site. The network of the Corporate Headquarters and the location in China both use a bus topology in both networks there is a single 100BaseT line that is either connected to a server or an interface device. The other two site Albany, Georgia and Pontiac, Michigan both use what seems to be a partial mesh topology or a hybrid topology. The servers on these networks are all connected together , the interface devices are connected to the server, and the clients and printers are then connected to only the interface devices. All of the locations have their own local area network which is connected to the Corporate Headquarter though a point to point connection which is a star topology. The China location has a point to point connection with the use of a satellite. . The networks of Riordan Manufacturing are all connected to the internet by VoIP/Data routers. _______ Communication Protocols Communication protocols are primarily standards for the process of transferring, sending, and receiving data and information. Without the use of communication protocol there will not be the possibility...

...competitors in the business-to-consumer segment, the company was able to survive by streamlining and focusing its business to achieve profitability. In January 2007, iPremier experienced a denial of service ("DoS") attack, which prevented access to the website and the internal web server. It was unclear at the time whether this was a DoS attack, or something deliberate. Though the attack appeared to be harmless in the end, the incident brought to light the fact that iPremier was ill-equipped to deal with breaches of network security. The incident highlighted three major shortcomings of the company's existing network security infrastructure: (1) a third party was responsible for the company's internal network security, (2) iPremier's information technology was outdated, and (3) iPremier's standards and procedures for dealing with security issues were out-of-date and poorly defined. Information security is necessary for protecting valuable information. Inadequate security could lead to a loss in confidence from shareholders and from customers all impacting future profits. Companies that collect financial information have a higher incentive to protect this information because of...

...For the integrative network design project, we were to choose from the virtual organizations given on how to upgrade their networks to meet their specific needs. The virtual organization that has been chosen to look at is Kudler Fine Foods, who wanted a Wan to tie all three locations together, to make the internal network configuration in each store a WAN, add VOIP to the multi-store network, figure out which store will house the central servers, and make sure the network is expandable beyond the existing stores. We will be giving a final network design. Specifically in the final network design, we are going to give a timeline for the project, explain the design approach and rationale, analyze the detailed design, prove the design meets the requirements set by Kudler Fine Foods, analyze the current security situation, identify electronic and physical threats to the network, describe potential threat detections and protection techniques, explain the importance of explicit enterprise security policies and procedures, describe how firewalls mitigate some network attack scenarios, describe common security concerns inherent to wired, wireless, and mobile network and design a security hardware and software environment that will protect the organization. The first area we will look at is the design of the new network. The new network will have an overall network architecture of a star network in a WAN or wide area network. Both of these network architecture allow for easy expansion...

...IT Audit Seminar organized by National Audit Office, China 1 to 4 September 2004 Paper on “Formulation of IT Auditing Standards” By -- Ms.Puja S Mandol and Ms. Monika Verma Supreme Audit Institution of India Introduction The use of computers and computer based information systems have pervaded deep and wide in every modern day organization. An organization must exercise control over these computer based information systems because the cost of errors and irregularities that may arise in these systems can be high and can even challenge the very existence of the organization. An organizations ability to survive can be severely undermined through corruption or destruction of its database; decision making errors caused by poor-quality information systems; losses incurred through computer abuses; loss of computer assets and their control on how the computers are used within the organization. Therefore managements across the world have deployed specialized auditors to audit their information systems to find out gaps between declared policies and actual use and shortcomings in the information system design and usage. Information Systems Audit is the process of collecting and evaluating evidence to determine whether a computer system has been designed to maintain data integrity, safeguard assets, allows organizational goals to be achieved effectively and uses the resources efficiently. The IS Auditor should see that not only adequate internal controls exist...

(D1-D6) The S6 coordinated and worked with the HICON to establish interoperability to ensure the data flow passed both ways. Due to challenges on HICONs part, the Regiment was unable to establish the digital COP they had developed prior to the Rotation. * Force-on-force. Offence (X1- X6). The S6 faced challenges of integrating staff cells that had not participated in previous exercises. Based on the commander’s intent for analog communications and battle tracking, the S6 faced many challenges with the terrain in the MRA. By tasking his RTNS units to be TACON to the Maneuver Squadrons, the S6 had a hard time refining the RTNS teams and adjusting their locations for optimal comms. Significant challenges for jumping the Regimental TOC were identified and captured in SOPs and Battle drills. * Defense (X8-X11) During the defense the S6 planned optimal RTNS locations, established 3 RTNS, and maintained control of the RTNS. Again the MRA terrain challenged the FM communication between the maneuver Squadrons and RTOC, however met the CDRs intent by providing FM Comms to the TAC.

...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 and...

...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 network and its interfaces can buffer backed-up...

...Unit-4 (ICS -305) Information security Information security (ISec) describes activities that relate to the protection of information and information infrastructure assets against the risks of loss, misuse, disclosure or damage. Standards that are available to assist organizations implement the appropriate programs and controls to mitigate these risks are for example BS7799/ISO 17799, Information Technology Infrastructure Library and COBIT. Information security management (ISM) describes controls that an organization needs to implement to ensure that it is sensibly managing these risks. Security Challenges The risks to these assets can be calculated by analysis of the following issues: Threats to your assets. These are unwanted events that could cause the intentional or accidental loss, damage or misuse of the assets Vulnerabilities. How vulnerable (prone or weak) your assets are to attack Impact. The magnitude of the potential loss or the seriousness of the event.

...INDP Final Kudler Fine Foods Network Design Project NTC 362 March 17, 2014 Introduction This paper will present the Final Integrative Network Design outlining the cumulative plan that Kudler Fine Foods has accepted and agreed on for implementation of the following: Final Network Design The integrative network design project for Kudler Fine Foods will include Transmission Control Protocol/ Internet Protocol (TCP/IP) will be used as a means of communication within a private network or the internet for Kudler Fine Foods network devices. Hypertext Transfer Protocol (HTTP) is used for transfer of multimedia files, video, sound, and text over the internet. Kudler Fine Foods will implement File Transfer Protocol (FTP) to download files, transfer files, delete files, copy and rename files from the internet as needed. Mesh Protocol will be used to connect all devices such as printers, computers, and scanners on the network. In a true mesh topology every node has a connection to every other node in the network ("Common Physical Network Topologies ", 2014). The network will consist of a hardware firewall blocking unwanted access from outside of the location. The next step is to set up a hub or switch that will connect all of the stores terminals. All of these terminals such as registers and remote locations such as warehouse will be hardwired with twisted pair CAT 5 Ethernet cable. The server will be located in a room in each store with the hub or switch. A wireless...
