VIRTUAL PROTOCOL NETWORK (VPN) - Coggle Diagram
VIRTUAL PROTOCOL NETWORK (VPN)
WHAT IS VPN?
A virtual private network (VPN) extends a private network across a public network and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network.The benefits of a VPN include increases in functionality, security, and management of the private network. It provides access to resources inaccessible on the public network and is typically used for telecommuting workers. Encryption is common, although not an inherent part of a VPN connection.
Site-to-site
What is site to site?
A site-to-site configuration connects two networks. This configuration expands a network across geographically disparate offices, or a group of offices to a data center installation. The interconnecting link may run over a dissimilar intermediate network, such as two IPv6 networks connected over an IPv4 network.
The benefit of Site to Site VPN
Security
Site-to-site VPN security is the most important benefit, as IPsec protocols will ensure all traffic is encrypted in transit through the VPN tunnel. The site-to-site VPN tunnel only allows traffic from one end to the other, blocking any attempts to intercept the traffic from the outside.
Scalability
When compared to a traditional VPN, a top benefit of a site-to-site VPN is its scalability. Rather than needing to ensure each employee system is running VPN client software as if it were on a remote access VPN, a site-to-site VPN only requires a VPN gateway at each location
Lower latency
If an organization needs improved performance, a site-to-site VPN can be configured to lower latency by using MPLS to route traffic over a VPN provider's infrastructure rather than through the public internet.
Managed services options
A site-to-site VPN can be run as a fully managed service by a managed security service provider. This may be a less costly option for smaller companies that don't have the budget to invest in security products and the staff to manage them.
What is IPsec?
IPsec is a group of protocols that are used together to set up encrypted connections between devices. It helps keep data sent over public networks secure. IPsec is often used to set up VPNs, and it works by encrypting IP packets, along with authenticating the source where the packets come
from.
Remote access
What is remote access?
A host-to-network configuration is analogous to connecting a computer to a local area network. This type provides access to an enterprise network, such as an intranet. This may be employed for telecommuting workers who need access to private resources, or to enable a mobile worker to access important tools without exposing them to the public Internet.
The
benefit
of remote access
Remote Access to Information Anytime
Regardless of location, VPNs can be used by employees anytime and anywhere, as long as there’s internet and an approved device being used.
Data security
VPN keeps your business, employees, and valuable client data off public networks.
Access to Blocked Websites
If you have employees traveling internationally, replacing your IP address with your VPN could be a necessity in countries with restricted access to sites.
Affordable for Business
VPNs are surprisingly affordable for businesses and their advanced features offer a major bang for their buck.
Boost Productivity
Easy 24×7 access to a secure network helps employees get their work done faster and collaborate by sharing files through a private network.
Better Work Life Balance
Employees no longer need to spend hours stuck in traffic or take time off for emergencies. Remote work from VPNs create more flexible work hours where employees are happier and have a greater sense of control and ownership over their own lives.
