Introduction

We have done literature review on important VPN technologies and issues. We have
explained the significance of VPN for contemporary organisations and discussed the role of
VPN to support the security of businesses.
Objective:
We study the processes and the security technologies being used when we access any
website (which uses HTTPS) online via a web browser. The Internet is a public network and
every single message we exchange with the server can potentially be intercepted by
attackers. We need to analyse in detail what technologies and techniques are used to
prevent attackers from modifying the communication between us and the web server and
what keeps our passwords and other details safe.
Significance of VPN for contemporary organisations ( Comparison of SSL/VPN and
IPSEC/VPN )
IPSEC is a protocol that helps in securing internet protocol communications by
authenticating and encrypting each IP packet of a communication carried whereas SSL are
cryptographic protocols which are designed to provide communication security over the
internet. IP layer protocol resides in the 3 layer and SSL in the 7 layer. IPSEC enables the
sending and receiving of cryptographically protected packet of any kind ( TCP, UDP, ICMP)
without any modification. SSL mostly utilized to protect http transactions and has been used
for other purposes like IMAP and pop.
Role of VPN to support the security of businesses
A VPN is a secure tunnel for online browsing. The technology helps you establish a
secure and encrypted connection over the internet between your device and the server. It
masks your device's identity and encrypts data that your PC or mobile phone pushes out
onto the internet. Companies that employ a site-to-site VPN can benefit from enhanced
collaboration without worrying about the security of their data. Security – The main reason
why businesses choose to adopt virtual private networks. Having encrypted data,
particularly if it is of a sensitive nature, is vitally important.
