How Does a VPN Work?
A virtual private network, or VPN, encrypts your internet traffic and routes it through an intermediary server in a remote location. This creates an encrypted tunnel between your device and the VPN server.
Here is a more detailed look at how VPNs work:
- When you connect to a VPN server, your traffic is encrypted using protocols like OpenVPN or IKEv2/IPSec. This creates a secure tunnel between your device and the server.
- Your traffic is routed through an intermediary VPN server located in a different geographic region, which hides your real IP address and masks your location.
- The VPN server acts as an intermediary, relaying your encrypted traffic request to the destination website or internet service.
- The website receives the request from the VPN server’s IP address, not your real IP, so your identity and location are obscured.
- When the website sends data back, it goes back through the encrypted VPN tunnel to your device. The VPN decrypts the data so you can access the content.
How Does Antivirus Software Work?
Unlike VPNs, which encrypt network traffic, antivirus software works locally on your device to identify and neutralize malware.
Here is an overview of how antiviruses work:
- Antivirus programs contain a database of malware signatures – code patterns of known viruses, worms, trojans, spyware, and other threats.
- Antiviruses scan files, applications, and incoming network traffic on your device, looking for code signatures that match threats in the database.
- When antivirus software detects a match, it attempts to neutralize the threat by blocking it, quarantining the file, or removing the malicious code.
- Antivirus apps also utilize heuristics, a form of AI, to detect previously unknown threats based on analyzing code behavior and patterns.
- Many antiviruses also offer real-time protection. This scans files as you access them and monitors network traffic and system processes as they occur to identify threats.
- Most antiviruses allow you to schedule periodic quick scans to check for malware. Full system scans search the entire computer for threats but take longer.
A Key Comparison Between VPNs vs Antiviruses
VPNs and antiviruses may both enhance online security, but there are some key technical differences:
How They Work
