Virtual Private Networks: Security Benefits and Implementation Details

This presentation provides an overview of Virtual Private Networks (VPNs) and their importance in enhancing network security. It discusses how VPNs extend private network connections, enabling secure remote access and protecting against unauthorized access and data breaches. The presentation highlights the benefits of VPNs, including improved security, privacy, and the ability to filter IP addresses. It also explores complementary components such as Hadoop, cloud computing, and Virtual LANs (VLANs) that, when used in conjunction with VPNs, further strengthen network security. Hadoop is presented as an extension for company communication, cloud computing as a method for secure data storage, and VLANs as a means of network segmentation. The presentation concludes that implementing VPNs alongside these components significantly improves network security and enables secure remote access.

Components required
The various components required other than VPN
to make a network have more security are
Hadoop, VLAN and cloud computing

Name, Student Id 9
Hadoop
Hadoop is used as an extension of the various
applications and software used by the
company for communication with the clients
and customers n the market.

Name, Student Id 10
Cloud computing
The cloud computing is a technique of data
storage over the internet in a place known as
cloud.

Name, Student Id 11
Virtual- LAN
A virtual LAN is a process of dividing a network
in the network layer. LAN is a local area
network and the word virtual refers to the
integration of that network virtually.

Conclusion
Thus, it can be concluded from the presentation that the use of VPN along with
the other components can help provide better security to the network and
help in providing remote access.
