What Is a VPN and Why Use One at NC State?

A Virtual Private Network (VPN) creates a secure tunnel for your internet traffic, encrypting your data and masking your IP address. Think of it like a secret passageway for your online activity, preventing others from seeing what you’re doing or where you’re located. This is especially helpful when you are connected to public Wi-Fi networks, which are often less secure. At NC State, using a VPN isn’t just about security; it’s also about access. It allows you to connect to university resources like library databases, software licenses, and internal servers, regardless of your physical location. Whether you’re in the library, at home, or traveling abroad, the NC State VPN ensures you have the same access as if you were on campus.

How a VPN Works

A VPN works by creating a secure, encrypted connection between your device and a server. This server acts as an intermediary, forwarding your internet traffic and hiding your actual IP address. When you connect to the internet without a VPN, your traffic goes directly to the websites and services you use, and your IP address is visible. This can expose your location and make your browsing activity traceable. With a VPN, your traffic is encrypted, making it unreadable to anyone who might try to intercept it. The VPN server then sends your request to the internet, and the response is sent back through the encrypted tunnel to you. This process keeps your online activity private and secure.

Here’s a breakdown:

• Encryption: The VPN encrypts your data, turning it into a scrambled format that is unreadable without the encryption key. This protects your information from eavesdropping. Encryption protocols like OpenVPN, IKEv2/IPsec, and WireGuard are used to ensure the data is secure. These protocols employ complex mathematical algorithms to encrypt your data. For example, AES (Advanced Encryption Standard) with a 256-bit key is a common encryption method that is considered very secure.
• Tunneling: The VPN creates a “tunnel” through which your internet traffic travels. This tunnel is a secure, private connection that keeps your data from being intercepted. The tunneling process involves encapsulating your data packets within another protocol, which then transports the encrypted data. VPNs use different tunneling protocols like PPTP (Point-to-Point Tunneling Protocol), L2TP/IPsec (Layer 2 Tunneling Protocol), and SSTP (Secure Socket Tunneling Protocol), each with different characteristics regarding speed and security.
• IP Masking: The VPN server

VPN Security Features

Security is a key advantage of using an NC State VPN. VPNs use a combination of technologies to safeguard your data. This includes robust encryption protocols, such as OpenVPN, IKEv2/IPsec, and WireGuard, which scramble your data into an unreadable format. These protocols vary in speed and security levels, so it’s essential to understand the differences. Another vital aspect is the use of a “kill switch,” which automatically disconnects you from the internet if the VPN connection drops, preventing any unprotected data leakage. Also, VPNs employ DNS leak protection, which prevents your DNS queries from leaking to your ISP, preserving your browsing privacy. Regular security audits are performed to confirm the VPN service remains secure. The network firewall protects from any intrusion.

Consider these aspects:

• Encryption Protocols: Various encryption protocols, like OpenVPN, IKEv2, and WireGuard, provide different levels of security and speed. OpenVPN is generally considered very secure and versatile, while IKEv2 offers fast connections. WireGuard is a newer, faster protocol with good security. The choice of protocol affects your VPN’s performance.
• Kill Switch: A kill switch is a feature that automatically cuts your internet connection if the VPN connection drops. This prevents your actual IP address and browsing activity from being exposed. If the VPN connection is lost, a kill switch ensures your privacy by immediately stopping all internet traffic until the VPN connection is re-established.
• DNS Leak Protection: DNS (Domain Name System) translates website names into IP addresses. DNS leak protection prevents your DNS queries from leaking to your ISP, preserving your privacy. When using a VPN, it’s vital to ensure that your DNS requests go through the VPN’s secure servers, and this is why DNS leak protection is enabled.
• Firewall: A firewall is an important security tool that protects your computer from unauthorized access by blocking malicious traffic. It acts as a barrier between your computer and the internet, monitoring incoming and outgoing network traffic and preventing unwanted connections. The firewall is integrated into your operating system.

Web Proxies vs. VPNs

Web proxies and VPNs both help to hide your IP address and mask your online activity, but they work very differently. A VPN encrypts all of your internet traffic. This provides a high level of security and privacy across all your online activities. A web proxy, on the other hand, only encrypts the traffic that goes through your web browser, such as HTTP and HTTPS requests. This means that a VPN provides broader protection compared to a web proxy, as it shields all of your internet traffic. A proxy is usually faster to set up and may be an alternative if a full VPN client is not working.

Here’s a comparison:

Feature	VPN	Web Proxy
Encryption	Encrypts all internet traffic	Encrypts browser traffic only
Security	Higher level of security	Lower level of security
Installation	Requires client software	Often accessible through browser settings
Impact on Speed	Slightly slower	Faster, but not as secure
Cost	Usually more expensive	Often free or cheaper

Other Access Methods

Besides the VPN and web proxies, there are other strategies to secure your connection. For certain tasks, using a secure shell (SSH) connection can be a useful alternative. SSH is particularly helpful for accessing command-line resources on university servers. For general browsing, always ensure you’re using HTTPS sites, as HTTPS encrypts the data between your browser and the website. Also, using a secure Wi-Fi connection, ideally one that requires a password, can enhance security. These access methods each have different purposes and benefits. Understanding the alternatives lets you choose the right approach for your needs.

• HTTPS: Make sure you are using sites that begin with “HTTPS.”
• SSH: Use SSH connections for secure access to command-line resources.
• Secure Wi-Fi: Use secured Wi-Fi networks with passwords.
