Protecting a virtual private network from cyberattack.

The Cybersecurity Directorate of the U.S. National Security Agency warns that virtual private networks may be vulnerable to cyberattack.


A new cybersecurity advisory issued by the National Security Agency's (NSA) Cybersecurity Directorate warns that virtual private networks (VPNs) may be vulnerable to cyberattacks.

VPNs, which are used by corporations and other organizations to establish private, encrypted connections to another network over the Internet, have garnered attention from potentially malicious cyber actors as more employees work remotely due to the pandemic.

The advisory indicates that VPN gateways especially are "prone to network scanning, brute force attacks, and zero-day vulnerabilities."

Said the NSA, "[N]etwork administrators should implement strict traffic filtering rules to limit the ports, protocols, and IP addresses of network traffic to VPN devices."
