Assignment Description

Network security is a process to secure the computer network system from all sorts of security threats, including threats to the physical set up. In this assignment, your task is to identify and evaluate network security threats that relate to network monitoring. You may, for example, investigate the network in the Institute, at your home or of the Internet by using any network security tool.

Use any TWO open source network monitoring and analysis tool mentioned below:

 GFI LanGuard  PRTG
 Nmap
 Metasploit
 TCPdump
 Open VAS

After scanning the network, compare and discus results on the threats these tools could be used for network monitoring and analysis. Also provide appropriate mitigation and countermeasure strategies for the identified threats and vulnerabilities.

Submission Guidelines

Your report should include and discuss all the results in detail with appropriate screenshots. Report should investigate and show originality of work, and be different from others.

1. Introduction to Nmap and PRTG
For finding the network vulnerabilities, the network monitoring tools are playing very important and critical role in modern era. By network monitoring, the occurred vulnerabilities to network can be identified and network security can easily be improved. 
The Nmap and PRTG are freeware tools available for network monitoring. The Nmap application provides a service and host discovery by creating a map of complete network. For identifying the network vulnerabilities, the specially created packets are send to all connected hosts to network by Nmap and on bases of their response, the network vulnerabilities are identified. Most of the OS are supported by Nmap. The facilities of accepting a scan during congestion and latency makes Nmap suitable to find network vulnerabilities. The Nmap includes the main features to detection of vulnerability, detection of advance services and discovery of network services and connected hosts [Shand & Tryfonas, 2008]. 
Like Nmap, “Paessler Route Traffic Grapher” commonly known as PRTG is another network monitoring tool to find the network vulnerabilities. The SNMP frames are being analyzed by PRTG and a graph of result is generated, so that any vulnerability to complete network traffic can be identified. The sniff facility of PRTG for identifying network vulnerabilities makes it very suitable for network monitoring. 
2. Literature reviews on findings 
The network security threats can occur from different methodologies deployed by any attacker or inducer. The attackers can make use of below listed methodologies for creating issues to created network: 
1. Malware: It is small computer program which creates Trojan horses, malicious root kits, worms and viruses for create network. The infection from one node to other is distributed by this methodology and complete network security issues are arrived. 
2. Spyware: This is another technique used to create network security issues in a spy manner.
