The definition of VPN (Virtual Private Network) is a private network that is used to connect devices to the internet network using high encryption.VPN can be used to increase security and privacy when accessing the internet, as well as providing access to restricted networks.
Understand VPN Functions in Remote Access
The main function of VPN is in remote access, VPN is used to access office networks remotely, such as access to files and applications that are only available on the office network.
VPNs are also used to increase security when accessing the internet remotely, by encrypting sent and received data.
Apart from that, VPN can also be used to access sites that are blocked or have restricted access, by changing the virtual location of the device.
Security
Protection from network attacks
VPN provides protection from network attacks, such as man-in-the-middle, sniffing, and phishing, by encrypting the internet connection. VPNs can also provide access authentication to prevent unauthorized access to the network.
Data encryption
VPN encrypts data sent and received over the network so that only the party who has the encryption key can read the data. This data encryption can protect personal and confidential company data from hackers.
Access authentication
VPNs provide access authentication mechanisms, such as passwords or tokens, to ensure only authorized users can access the network.
This access authentication can prevent unauthorized access to the network and protect data from attacks.
Understanding VPN Functions in Remote Access
Access office networks remotely
VPN allows users to access the office network remotely, such as access to files and applications that are only available on the office network. This allows workers to work from anywhere without physical location constraints.
Access limited applications and data
VPN can be used to access applications and data that are only available on the office network, such as ERP or CRM applications.
This allows workers to remain productive and connected to the office network, even though they are away from the office.
Manage access to specific systems
VPNs can be used to regulate access to specific systems, such as servers or applications, only to users who have access rights.
This can improve network security and prevent unauthorized access to critical systems.
Advantages of VPN
Better security
VPN provides stronger encryption and access authentication, thereby minimizing the risk of network attacks and protecting personal data.
This can improve network security and protect companies from financial and reputational losses.
Flexibility of remote access
VPN allows workers to work from anywhere, allowing companies to save office costs and expand market coverage. This can increase work efficiency and productivity of workers.
Better access control
VPNs can be used to regulate access to specific systems, allowing companies to control unauthorized access and improve network security. This can improve network efficiency and reduce network security risks.
How VPNs Work
Establishment of an encrypted connection
VPN creates an encrypted connection between devices used for remote access and the office network.
This protects the data sent and received from network attacks and monitoring by third parties.
Access authentication
VPNs use access authentication methods, such as passwords or tokens, to verify the identity of users accessing the office network.
This allows only authorized users to access the office network.
Network routing
A VPN routes network traffic through an encrypted connection, allowing access to the office network remotely.
This allows workers to stay connected to the office network and access applications and data that are only available on the office network.
Types of VPNs
VPN Site-to-Site
Site-to-Site VPN is used to connect two different physical locations, such as a branch office and a head office. This allows secure and seamless access to different office networks.
VPN Remote Access
VPN Remote Access is used to allow users to access an office network remotely, such as from home or a different place of work.
This allows workers to stay connected to the office network and access applications and data that are only available on the office network.
VPN Mobile
Mobile VPN is used to allow users to access office networks via mobile devices, such as smartphones or tablets.
This allows workers to stay connected to the office network while outside the office, such as when traveling or at a different work location.
