Log Information Security

Log Information Security


Logs record information such as user operations on devices and device running status. Stored as log files on devices, logs help network administrators monitor the running status of routers and diagnose network faults.

Security Policy

Log security is ensured by the access mode authentication and socket security. Logs can be viewed in the following modes:

  1. A user accesses a device to view logs by using command lines.

  2. A user copies log files to a local disk over FTP. Diagnosis logs must be parsed by a parsing tool.

  3. A user sends logs to the log server when a log host is configured.

In the preceding modes, users must pass the password, AAA, or public-key authentication and successfully access devices to view logs online or obtain log files. When a log host is configured, socket must be used to protect data.

Configuration and Maintenance Methods

See the configuration maintenance in the Console, Telnet, SSH, TFTP, and Socket authentication modes.

Configuration and Maintenance Suggestions
