Sites That Accept Credit Card For Payments Score Low On Security (Stay Safe With a VPN, Where Your Data Is Encrypted)

April 25, 2017 Posted in Privacy News by No Comments

You can make all sorts of payments online ranging from debit cards, credit cards, e-wallets, cryptocurrencies such as bitcoin, and much more. You would think that since websites are accepting all types of payment, their security would be up to the mark. Contrary to popular beliefs, websites that accept credit card payments score low on security. Even though security systems are becoming increasingly complex, it’s hard for security professionals to know about every single loophole in their system. Hackers use these vulnerabilities to intercept the data or gain access to personal data of the users. By using a VPN, you can stay safe as your data is encrypted

Why Should You Use a VPN?

Virtual Private Network or VPN is a group of private networks that are connected together over a public network. Imagine it to be your home network. If your router is secured properly, no one outside the network can access your data, unless someone has access.

Remote Access Server (RAS)

In order to connect to a VPN, both the client and the VPN provider need dedicated software. When your device connects to a VPN, it connects to the Remote Access Server (RAS). Based on the credentials provided by the user, RAS authenticates it. This is the first layer of security in a VPN.

Tunneling and encapsulation

The client uses a software to connect to the VPN which sets up a tunneled connection to the RAS. The process of sending data privately over the internet using a VPN is called tunneling. Data that is sent across the internet is sent in the form of small pieces called packets. Each packet contains additional information such as the protocol, it is being used for and the IP address of the sender.

When VPN tunnels a connection, each of these packets is placed inside another data packet before it is transmitted. This process is called encapsulation and this is the second layer of security in a VPN.

Encryption

The encapsulated data that is sent over the internet is also coded so that only the VPN and the client can read the data. This is called encryption. There are various security protocols used by VPNs to encrypt data. Layer 2 Tunneling Protocol, Point-to-point Tunneling Protocol, Layer 2 forwarding, Internet Protocol Security are a few security protocols used.

However, this is just the 3 fundamentals of security in a VPN. VPNs also have additional security features to ensure that your data is safe.
