What is VPN in Cybersecurity?
A Virtual Private Network creates an encrypted tunnel between a user's device and a remote network, protecting traffic from interception on untrusted networks. Site-to-site VPNs connect entire networks, while remote-access VPNs let individual users securely reach internal resources.
Why VPN Matters for Your Cybersecurity Career
VPN configuration and monitoring are core security engineering tasks. Misconfigured split tunneling, weak authentication, and unpatched VPN appliances have caused major breaches. Incident responders investigate VPN logs to trace unauthorized access. Penetration testers probe VPN endpoints for vulnerabilities.
