Description
The vpn-session-log is a specialized log file dedicated to recording all activities related to Virtual Private Network (VPN) sessions. This includes when users connect or disconnect, the identity or certificate used for authentication, the remote and assigned IP addresses, the encryption and tunneling protocols in use (like OpenVPN, IPsec, or WireGuard), and session-specific data such as connection time and bandwidth usage.
This log is an essential tool in enterprise and secure networking environments, where VPNs are used to provide remote employees, contractors, or systems with safe access to internal resources. The file supports troubleshooting by showing errors related to handshake failures, invalid certificates, or DNS leaks.
IT and security teams rely heavily on vpn-session-log files for compliance tracking, intrusion detection, and forensic investigation. For example, if a user reports a connectivity issue, the VPN log can confirm if the connection attempt was made and where it failed. Similarly, a security analyst might inspect the log to detect brute-force attempts, multi-login patterns from unusual geolocations, or expired keys being reused.
In larger organizations, this file is commonly fed into a centralized SIEM system or log aggregation platform to enable real-time monitoring, usage analytics, and alert generation. Logs may also show rekeying events, session renewals, or unexpected drops, offering insight into network health and reliability.
Most VPN daemons like openvpn, strongSwan, WireGuard, and commercial VPN appliances write structured entries into this log, which can also be configured to maintain different verbosity levels depending on the level of detail required.
