What Are Two Important Considerations When Designing a VPN?

A virtual private network, or VPN, is a network that you establish across the internet with the use of software, such as OpenVPN. By establishing a VPN, you can provide your internet traffic with a secure and private connection that travels across public internet spaces, such as hotels and cafes. This way, your personal information stays private even when you are away from your home network.

VPNs can be configured to meet the security standards and preferences of individual users or groups of users. In order to ensure the security of your network, you need to establish a strong security system that utilizes both ends of the VPN tunnel, which is where the name double VPN comes from. When a VPN is double VPNed, the data that you transmit is divided and encrypted twice, which makes it more secure. The second encryption prevents others from accessing your data, even if they have gained unauthorized access to the first encryption.

Since your data is protected and secure throughout the entire VPN, you do not need to worry about whether or not you are transmitting personal information in the clear. In most cases, you will be safer using a VPN than you would by simply using a public network.

Key Consideration: Scalability

One of the most important considerations when designing a VPN is the ability of the network to scale as your needs grow. You should strive for a VPN that is highly configurable and has robust performance regardless of how many clients you have connected to the network at one time. For instance, if you have a large network with many users who use your VPN frequently, you should opt for a VPN with a large number of shared IPs – often referred to as a hub and spoke network- which can spread the load across several servers, improving performance and reliability for all connected users. If you have a smaller network or just a single user, you can opt for a less resilient VPN and risk performance issues or even outages, which would compromise the security of your connection.

Another Important Consideration: Bandwidth

The second important consideration when designing a VPN is the amount of bandwidth that it consumes. You should opt for a VPN that uses minimal bandwidth since most companies that provide free VPN services have bandwidth restrictions, which can be frustrating for heavy internet users or users who stream videos or download large files regularly. If you have limited bandwidth, you should opt for a narrow bandwidth VPN.

The reason why bandwidth is so important is because your internet connection is likely to have bandwidth restrictions and the more data that you transmit, the more likely it is that you will exceed these restrictions. For example, many internet service providers, or ISPs, do not allow their customers to download or stream copyrighted material, so if you are violating this policy, you risk getting your internet connection suspended or terminated, at the very least. Moreover, if you are regularly exceeding your bandwidth restrictions, you run the risk of being throttled or billed extra by your internet service provider. In order to keep your internet connection fast and secure, you should not use up more than 50% of the available bandwidth – at least on your side of the connection.

How To Design A VPN

Since you will be handling a lot of sensitive information throughout your VPN, it is essential that you do so securely. For this reason, you should not use weak encryption or a default password, and you should never log in to the system with an unsecured network connection. Once you have established a secure connection, you should change your password immediately.

Changing your password is critical for several reasons. First, it helps keep your personal information secure and it also ensures that nobody else can access your account, even if they get ahold of your password. Second, you should not reuse your password, and you should generate passwords that are unique and hard to guess. Third, you should change your password every few months to help ensure that your account does not become compromised by someone who has spent too much time figuring out your old password. Finally, you should avoid using passwords that contain personal information because even if they do not contain any personal information, they can still be used to identify and locate you.
