VPNs (Virtual Private Networks) have helped companies and individuals make their Internet networks more secure and reliable. VPNs are important for many other reasons than simply just to unblock networks, and they’re becoming almost necessary for Internet security. Most companies are using VPNs nowadays, and if your company is not then you should consider using one. But aside from just using a VPN, you need to make sure you’re using the right VPN.
When considering a VPN service provider, be absolutely sure that this provider uses these technologies in order to keep both your connection and data secure.
Since your private data will be traveling over a public network, making sure your VPN provider offers data confidentiality is absolutely vital for security. Most VPN providers will take all the data being sent from one computer to another and encrypt it, and then decrypt it when it reaches the other computer. There are three common protocols that most VPNs use, and they are:
- PPTP (Point-to-Point Tunneling Protocol)
- L2TP (Layer 2 Tunneling Protocol)
- SSTP (Secure Socket Tunneling Protocol)
Make sure your VPN provider uses one of these protocols for maximum security for your network. Having an anonymous VPN is vital for network security.
In addition to making sure that the data you’re sending is encrypted over the public network, it’s also vital that your VPN makes sure that the data hasn’t been changed while traveling over that network. IPsec is able to ensure that the data being sent hasn’t been tampered with, and has ways to drop the data if it has been tampered with. It’s very important that your VPN has a way to detect if data has been tampered with.
An important part of data integrity is data origin authentication. Data origin authentication means verifying the origin and source of the data that’s being sent. Common hacking techniques involve masking the identity of the sender, which is why having data origin authentication is important to the overall security of your network.
AAA stands for authentication, authorization, and accounting, and it’s used for even more security with a remote-access VPN. AAA requires user authentication, meaning anybody who uses a computer with pre-configured VPN client software must log into the network in order to access the VPN.
When using a VPN with AAA, the VPN will check the user name and password of the person attempting to send the data. It then checks the following:
- Who you are
- What you have authorization to do
- What it is that you are doing
Having AAA with your VPN is important because it allows for tracking of client use, and can come in big handy for billing and auditing.
Having a secure, confidential, and fast network is necessary. If your business deals with a lot of confidential information, failing to find a VPN with all of the above securities means you’re putting your data at risk. Consider switching VPNs if your provider doesn’t offer all of the above, as you should be able to get all the security for not much more cost.
