Mapping a Network Using FriendlyPinger

Friendly Pinger is a user-friendly application for network administration, monitoring, and inventory

Lab Scenario

in die previous lab, you found die SNA IP, ICMP Ping, Nodes Mapped, etc. details using die tool LANSurveyor. If an attacker is able to get ahold of this information, he or she can shut down your network using SNMP. They can also get a list of interfaces on a router using die default name public and disable diem using die readwrite community. SNMP MIBs include information about the identity of the agent's host and attacker can take advantage of diis information to initiate an attack. Using die ICMP reconnaissance technique an attacker can also determine die topology of die target network. Attackers could use either die ICMP ,’Time exceeded" or "Destination unreachable" messages. Bodi of diese ICMP messages can cause a
host to immediately drop a connection. As an expert Network Administrator and Penetration Tester you need to discover network topology and produce comprehensive network diagrams for discovered
networks and block attacks by deploying firewalls on a network to filter un-wanted traffic. You should be able to block outgoing SNMP traffic at border routers or firewalls. in diis lab, you will leani to map a network using die tool Friendly Pinger.

Lab Objectives

The objective of diis lab is to help students discover and diagram network topology and map a discovered network.

in this lab, you need to:

■ Discover a network using discovery techniques
■ Diagram the network topology
■ Detect new devices and modifications made in network topology
■ Perform inventory management for hardware and software assets

Lab Environment

To perform die lab, you need:

■ Friendly Pinger located at D:\CEH-Tools\CEHv8 Module 03 Scanning Networks\Network Discovery and Mapping Tools\FriendlyPinger
■ You can also download the latest version o f Friendly Pinger from the link h ttp :// www.kilievich.com/fpinge17do\vnload.htm
■ If you decide to download the latest version, dien screenshots shown in die lab might differ
■ A computer running Windows Server 2012
■ A web browser widi Internet access
■ Administrative privileges to run die Friendly Pinger tool

Lab Duration

Time: 10 Minutes

Overview of  Network Mapping

Network mapping is die study of die physical connectivity of networks. Network mapping is often carried out to discover servers and operating systems ruining on networks. This tecluiique detects new devices and modifications made in network topology You can perform inventory management for hardware and software
assets.
Friendly Pinger performs the following to map the network:

■ Monitoring network devices availability
■ Notifies if any server wakes or goes down
■ Ping of all devices in parallel at once
■ Audits hardware and software components installed on the computers over the network

Lab Analysis

Document all die IP addresses, open and closed ports, services, and protocols you discovered during die lab

Questions
1. Does FPinger support proxy servers firewalls?
2. Examine the programming of language used in FPinger .
