Packet Tracer

Packet Tracer is a cross-platform visual simulation tool designed by Cisco

Systems that allows users to create network topologies and imitate modern

computer networks. The software allows users to simulate the configuration of

Cisco routers and switches using a simulated command line interface. Packet

Tracer makes use of a drag and drop user interface, allowing users to add and

remove simulated network devices as they see fit. The software is mainly focused

towards Cisco Networking Academy students as an educational tool for helping

them learn fundamental CCNA concepts.

Installation of Packet Tracer:

Step 1: Visit the official website of Netacad using any web browser.

Step 2: Press the login button and select log In option.

Step 3: Next screen will appear, click on the sign-up option.

Step 4: Step 4: Next screen will appear and will ask for email and password and other

Step 5: Now the login screen appears again so fill in the Email id.

Step 6: On the next screen enter the password and press the Login button.

Step 7: Dashboard will initialize, now click on Resources and choose Download Packet

Tracer Option.

Step 8: On the next web page choose the operating system to download the packet

tracer. Downloading will start automatically.

Step 9: Check for the executable file in your system and run it.

Step 10: Next screen is of License Agreement so Click on I accept the license

Step 11: Choose the installing location which has sufficient space.

Step 12: Select the start menu folder and click the Next button.

Step 13: Check the box for creating a desktop icon and click on the Next button.

Step 14: Now packet tracer is ready to install so click on the Install button.

Step 15: The installation process will start and will hardly take a minute

Step 16: Click on the Finish button to complete the installation.

Step 17: An icon is created on the desktop so run it.

Step 18: Interface is initialized and the software is ready to use.

Uses of Packet Tracer:

Packet Tracer offers an effective, interactive environment for learning networking

concepts and protocols. Most importantly, Packet Tracer helps students and

instructors create their own virtual “network worlds” for exploration,

experimentation, and explanation of networking concepts and technologies.

2. Metasploit

The Metasploit framework is a very powerful tool which can be used by

cybercriminals as well as ethical hackers to probe systematic vulnerabilities on

networks and servers. Because it's an open-source framework, it can be easily

customized and used with most operating systems.

Installation of Metasploit

Step 1: If you have not installed termux then install it from the play store.

Step 2: Run the following command :

$ apt update

$ apt upgrade -y

Step 3: Install the required packages using this command:

$ pkg install wget curl openssh git -y

Step 4: Now we need to install nucurses utility programming library

$ apt install ncurses-utils

Step 5: We have fulfilled all the necessary requirements for Metasploit 6. Now run only

single command to install Metasploit 6:

$ source <(curl -fsSL https://kutt.it/msf)

Metasploit 6 is successfully installed on your device you can check it using the below

command:

$ metasploit

Uses of Metasploit

The Metasploit Framework is an open source platform that supports vulnerability

research, exploit development, and the creation of custom security tools.

3. Splunk

Splunk is a software mainly used for searching, monitoring, and examining

machine-generated Big Data through a web-style interface. Splunk performs

capturing, indexing, and correlating the real-time data in a searchable container

from which it can produce graphs, reports, alerts, dashboards, and visualizations

Installation of Splunk

1. Download latest splunk version from below llink.Select appropriate version

32/64 bit of operating system.splunk exe size is around 93.8MB

2.. Once download is complete open the folder in which splunk is downloaded and

double click on splunk-6.2.1-245427-x64-release.msi or
