What technology is commonly used to secure communications in maritime operations?

In maritime operations, the common use of Virtual Private Networks (VPNs) to secure communications is crucial. VPNs create a secure tunnel over the internet, allowing data to be transmitted safely between devices even when using potentially insecure networks. This technology is particularly important in maritime environments where vessels often rely on satellite or other wireless communications that may be vulnerable to eavesdropping or tampering. By employing a VPN, crews can ensure that sensitive information, such as operational data or personal communications, is protected from unauthorized access.

While firewalls, encryption software, and secure data protocols all play important roles in cybersecurity, a VPN specifically addresses the need for a secure communication channel over the diverse and often unsecured networks typical in maritime operations. These elements may complement each other, but the distinctive ability of a VPN to provide secure remote access and protect the integrity of data transmissions aligns closely with the requirements of safeguarding maritime communications.
