VPN Flashcards
what is VPN used for
Security, Privacy, Access to restricted content, Remote access & Cost saving
VPN security advantage
A VPN encrypts all the data that is transmitted between your device and the remote server, making it difficult for anyone to intercept and access your data. This is particularly important when using public Wi-Fi networks, which are often unsecured and can be easily hacked.
VPN Privacy advantage
A VPN hides your IP address and location from the websites and services you access, making it difficult for them to track your online activity. This helps protect your privacy and anonymity online.
VPN to access restricted content
A VPN can allow you to access content that is blocked in your region or by your Internet Service Provider (ISP). By connecting to a server in a different location, you can bypass these restrictions and access the content you need.
VPN to remote access
A VPN can provide remote access to a private network, allowing employees to access company resources securely from anywhere in the world.
VPN economic advantages
A VPN can reduce costs associated with expensive private networks and leased lines, making it a cost-effective alternative for businesses and organizations.
What is needed for a VPN tp work
VPN Client, VPN Server, VPN Protocol, Authentication and Encryption
What is a VPN Client
The VPN client is software that is installed on the user’s device, such as a computer or mobile device. It is responsible for establishing the encrypted connection to the remote server and providing access to the VPN.
What is a VPN Server
The VPN server is a remote server that receives the encrypted traffic from the VPN client and decrypts it, allowing access to the internet and other resources. The VPN server also encrypts the traffic that is sent back to the client, providing a secure connection.
What is a VPN Protocol
The VPN protocol is the method used to establish and maintain the secure connection between the client and the server. Common VPN protocols include OpenVPN, IKEv2, and L2TP/IPsec.
What is Authentication
Authentication is the process of verifying the identity of the user or device that is attempting to connect to the VPN. This can be done using a username and password, digital certificates, or other methods.
What is Encryption
Encryption is used to protect the data that is transmitted between the client and the server. This ensures that the data cannot be intercepted and read by unauthorized parties.
Explain “tunneling”
VPN’s use a method of tunnelling which is the process of encapsulating one protocol within another protocol for secure data transmission over an insecure network. It involves creating a tunnel or virtual pipe between two devices, where data is encrypted and then transmitted through the tunnel.
