Which of the following technologies is commonly used for remote access in CANES?

The technology commonly used for remote access in CANES is Virtual Private Network (VPN). A VPN creates a secure, encrypted tunnel over the internet, allowing users to connect to a private network from various locations. This is crucial for maintaining data security and ensuring that sensitive information remains protected while being accessed remotely. In a military context, like CANES, where secure communications are essential, the use of a VPN allows personnel to work effectively while adhering to security protocols.

The other options, while they pertain to different forms of communication and networking, do not provide the same level of secure, remote access. The Public Switched Telephone Network (PSTN) is primarily used for traditional telephone communications and lacks the encryption capabilities necessary for secure data transmission over the internet. Dedicated leased lines offer a direct connection but lack the flexibility and cost-effectiveness that remote access solutions like VPN provide. Lastly, Synchronous Optical Networking (SONET) is a standard for high-speed data transmission in fiber optic networks, but it is not designed for remote user access like a VPN is.
