...home LAN and its ISP. Overview OPNET’s IT Guru provides a Virtual Network Environment that models the behavior of networks, including its routers, switches, protocols, servers, and individual applications. The Virtual Network Environment allows IT managers, network and system planners, and operation’s staff to more effectively diagnose difficult problems, validate changes before they are implemented, and plan for future scenarios such as traffic growth and network failures. You can do “what if” analyses (called scenarios in IT Guru) on network designs, just as you can on spreadsheets with financial business models. However, instead of looking at “bottom line” financial numbers, you will be looking at how response times, latency (delays) and other network performance measures will change under different network design approaches. To create a network simulation (called a project in IT Guru), you specify the nodes (computers, switches, routers, etc.) in your network, the links between nodes, and the applications that will be running on the nodes. In this exercise, the initial simulation (project) has been built for you. It models a family’s ITCE 416: OPNET IT Guru Lab, Page 1 home PC network, which has three PCs connected to the Internet for game playing; web browsing, E-mail, audio streaming, and FTP (file transfer protocol). Your objective will be to conduct a series of what-if simulations (scenarios) to see how performance differs if the family connects to the...

...security policies for the site are properly implemented. Firewalls are the basis of computer and network security defense. They are widely deployed. They are very hard to configure properly, and people who configure them may not know the current threats and attacks. For example, an administrator maybe working on some task and might leave something open in a firewall where attackers can enter through. Some firewalls have the vulnerability that enables attackers and be defeated. By identifying the network components, you can evaluate their vulnerabilities. These vulnerabilities can have flaws in the technology, configuration, or security policy. Vulnerabilities can be fixed different ways, applying software patches, reconfiguring devices, or deploying countermeasures such as firewalls and antivirus software. Threat is when people take advantage of vulnerability and cause a negative impact on the network. If threat occurs it needs to be identified, and the associated vulnerabilities need to be addressed to minimize the risk. As of today, most of the hackers are interested in hacking services such as HTTP (TCP Port 80) and HTTPS (TCP Port 443), which are open in many networks. By using access control devices, they can detect malicious exploits aimed at these services. Now these days applications has improve and very hard for hackers to get into but the technology need to stay up to date and be more intelligent. The attack methodology requires firewalls to provide not only access control...

...Research Assignment 1. Explain the function of the following Windows Server 2008 Services: A. Active Directory Federation Services B. Active Directory Lightweight Directory Services C. Active Directory Certificate Services D. Active Directory Rights Management Services AD FS is composed of three different server components: Federation Server, Federation Proxy server, and ADFS Web Agents. A federation server is the main AD FS component, which holds the Federation Service role. These servers route authentication requests between connected directories. A federation proxy server acts as a reverse proxy for AD FS authentication requests. This type of server normally resides in the demilitarized zone (DMZ) of a firewall, and is used to protect the back-end AD FS server from direct exposure to the untrusted Internet. The Web Agents component of AD FS hosts the claims-aware agent and the Windows token-based agent components that manage authentication cookies sent to web server applications. The Active Directory Lightweight Directory Services server role is a Lightweight Directory Access Protocol directory service. It provides data storage and retrieval for directory-enabled applications, without the dependencies that are required for Active Directory Domain Services. Active Directory Certificate Services provides customizable services for issuing and managing public key infrastructure (PKI) certificates used in software security systems that employ public key technologies...

...Tichaona Zvidzayi; 613z0022 Question 1 a) How SSL(Secure Socket Layer) works The reasons why SSL exists are encryption and identification (Vaughan-Nichols, 2013). Encryption hides the information moving between two computers and identification makes sure that you are talking to the right person. If the server cannot verify itself, the client (browser/server) displays a security warning because someone might be pretending to be a legit website for personal gains. Vaughan-Nichols, 2013 SSL stages: The client initiates a connection with the web-server and prompts the web-server to verify if it is a legit website. The website will then attempt to verify itself by sending a copy of SSL certificate. The client will then confirm if it can trust the website or not,...
