Experiment No – 1
Aim:- IntroductiontoCyber Security. Why we needCyber Security, importance of Cyber
Security andAdvantages & Disadvantages of Cyber Security.
Introduction to Cyber Security was designed to help learners develop a deeper understanding of modern
information and system protection technology and methods. The learning outcome is simple: We hope
learners will develop a lifelong passion and appreciation for cyber security, which we are certain will help
in future endeavors. Students, developers, managers, engineers, and even private citizens will benefit
from this learning experience. Special customized interviews with industry partners were included to help
connect the cyber security concepts to live business experiences
Why we need Cybersecurity?
It can be rightfully said that today’s generation lives on the internet, and we general users are almost
ignorant as to how those random bits of 1’s and 0’s reach securely to our computer. For a hacker, it’s a
golden age. With so many access points, public IP’s and constant traffic and tons of data to exploit, black
hat hackers are having one hell of a time exploiting vulnerabilities and creating malicious software for the
same. Above that, cyber attacks are evolving by the day. Hackers are becoming smarter and more
creative with their malware and how they bypass virus scans and firewalls still baffles many people.
Therefore there has to be some sort of protocol that protects us against all these cyber attacks and make
sure our data doesn’t fall into the wrong hands. This is exactly why we need cybersecurity.
Advantages of Cyber Security:
Improved security of cyberspace.
Increase in cyber defense.
Increase in cyber speed.
Protecting company data and information.
Protects systems and computers against virus, worms, Malware and Spyware etc.
Protects individual private information.
Protects networks and resources.
Fight against computer hackers and identity theft.
Disadvantages of Cyber Security:

It will be costly for average users.
Firewalls can be difficult to configure correctly
Need to keep updating the new software in order to keep security up to date.
Make system slower than before.

Experiment No – 2
Aim:- IntroductiontoCISCO Packet Tracer software and Describe all the tools
Cisco Packet Tracer as the name suggests, is a tool built by Cisco. This tool provides a network
simulation to practice simple and complex networks.
The main purpose of Cisco Packet Tracer is to help students learn the principles of networking with
hands-on experience as well as develop Cisco technology specific skills. Since the protocols are
implemented in software only method, this tool cannot replace the hardware Routers or Switches.
Interestingly, this tool does not only include Cisco products but also many more networking devices.
Using this tool is widely encouraged as it is part of the curriculum like CCNA, CCENT where Faculties
use Packet Trace to demonstrate technical concepts and networking systems. Students complete
assignments using this tool, working on their own or in teams.
Engineers prefer to test any protocols on Cisco Packet Tracer before implementing them. Also,
Engineers who would like to deploy any change in the production network prefer to use Cisco Packet
Tracer to first test the required changes and proceed to deploy if and only if everything is working as
expected.
Packet Tracer is a medium fidelity, network-capable, simulation-based learning environment for
networking novices to design, configure, and troubleshoot computer networks at a CCNA-level of
complexity. Packet Tracer is an integrated simulation, visualization, collaboration, and assessment
environment. Packet Tracer supports student and instructor creation of simulations, visualizations, and
animations of networking phenomena. Like any simulation, Packet Tracer relies on a simplified model of
networking devices and protocols. Real computer networks, experienced both in-person/hands-on and
remotely, remain the benchmark for understanding network behavior and developing networking skills.
Packet Tracer Modes: Cisco Packet Tracer provides two operating modes to visualize the behavior of a
network—real-time mode and simulation mode. In real-time mode the network behaves as real devices
do, with immediate real-time response for all network activities. The real-time mode gives students a
viable alternative to real equipment and allows them to gain configuration practice before working with
real equipment. In simulation mode the user can see and control time intervals, the inner workings of
data transfer, and the propagation of data across a network. This helps students understand the
fundamental concepts behind network operations. A solid understanding of network

fundamentals can help accelerate learning about related concepts.

A network hub is a central connection point for devices in a local area network, or LAN. But there's a limit
to the amount of bandwidth users can share on a hub-based network. The more devices are added to
the network hub, the longer it takes data to reach its destination. A switch avoids these and other
limitations of network hubs.
A large network may include multiple switches, which connect different groups of computer systems

together. These switches are typically connected to a router that allows connected devices to access
the Internet.

Experiment No – 5
Aim:- Implement Bus Topology and share data from one node toanother

will need a central device.
Step 2 :- From this list of switches you can use any one. But I personally recommend using model
2950-24 switch
Step 3:- End devices are another important aspect of a computer network. By end device we simply
mean any sort of device which is being used by user including computer, smartphone or printer. Type of
end devices that you will be using totally depends upon your needs. You can select devices of your
choice from toolbox menu titled as end devices.
Step 4:- Go to the ‘Connections Menu’ from the toolbox and select ‘Copper Straight Through Cable’ for
connecting all the end devices with the switch. This cable will serve as medium for transferring data from
one device to the other.
Step5:- For initiation of connections, first of all you will need to click ‘Copper Straight Through Cable’.
