Mitigation Strategy: Strict Channel Access Control (Sonic Configuration)

Mitigation Strategy: Strict Channel Access Control (Sonic Configuration)

Description:

  1. Configure Passwords: In Sonic's config.cfg, set strong, unique passwords for the search, push, and control channels using the [channel] section and the password option. Example: 
    [channel]
search = {
    password = "strongSearchPassword"
}
push = {
    password = "strongPushPassword"
}
control = {
    password = "strongControlPassword"
}
  2. Restart Sonic: Restart the Sonic service for the password changes to take effect.

Threats Mitigated:

  • Unauthorized Data Access (High Severity): Prevents direct, unauthorized querying of the search channel.
  • Unauthorized Data Modification (High Severity): Prevents direct, unauthorized use of the push channel.
  • Unauthorized Administrative Actions (Critical Severity): Prevents direct, unauthorized use of the control channel.

Impact:

  • Unauthorized Data Access: Risk significantly reduced (from High to Low).
  • Unauthorized Data Modification: Risk significantly reduced (from High to Low).
  • Unauthorized Administrative Actions: Risk significantly reduced (from Critical to Low).

Currently Implemented:

  • Passwords are set for all channels in config.cfg.

Missing Implementation:

  • Automated password rotation is not implemented (this would require external scripting and is not a direct Sonic configuration).

Mitigation Strategy: Control Channel Security (Sonic Configuration)

Mitigation Strategy: Control Channel Security (Sonic Configuration)

Description:

  1. Strong Control Password: As part of the "Strict Channel Access Control," ensure the control channel password in config.cfg is exceptionally strong and unique.
  2. Restart Sonic: Restart the Sonic service after changing the control password.

Threats Mitigated:

  • Unauthorized Administrative Actions (Critical Severity): Prevents attackers from gaining control of the Sonic instance.

Impact:

  • Unauthorized Administrative Actions: Risk significantly reduced (from Critical to Low).

Currently Implemented:

  • A strong password is set for the control channel in config.cfg.

Missing Implementation:

  • No direct Sonic configuration options exist for auditing control commands (this would require modifying Sonic's source code or using a proxy).
  • Automated password rotation is not a direct Sonic configuration.

Mitigation Strategy: Configuration Hardening (Sonic config.cfg)

Mitigation Strategy: Configuration Hardening (Sonic config.cfg)

Description:

  1. Review config.cfg: Thoroughly review all settings in Sonic's config.cfg file.
  2. timeout_ms_* Settings: Configure appropriate timeouts in the [network] section to prevent long-running operations:
    • timeout_ms_connect: Timeout for establishing a connection.
    • timeout_ms_read: Timeout for reading data.
    • timeout_ms_write: Timeout for writing data.
  3. log_path: Ensure the log_path in the [store] section points to a secure, restricted-access directory.
  4. Disable Unused Features: If any channels (search, push, control) are not used, consider disabling them (although this is primarily managed through application-level access control). There isn't a direct "disable" option in config.cfg, so this relies on not using the channel and securing it with a strong password.
  5. tcp_keepalive_ms: Set tcp_keepalive_ms to prevent half-open connections.
  6. Restart Sonic: Restart the Sonic service after making any configuration changes.

Threats Mitigated:

  • Denial of Service (DoS) (Medium Severity): Timeouts help prevent resource exhaustion from slow or malicious clients.
  • Information Leakage (Medium Severity): Secure log_path prevents sensitive information from being exposed in logs.

Impact:

  • Denial of Service (DoS): Risk reduced (from Medium to Low).
  • Information Leakage: Risk reduced (from Medium to Low).

Currently Implemented:

  • log_path is set to a secure directory.
  • Basic timeouts (timeout_ms_read, timeout_ms_write) are configured.

Missing Implementation:

  • A comprehensive review and optimization of all config.cfg settings for security has not been fully documented.
  • tcp_keepalive_ms is not configured.

Mitigation Strategy: Run as Non-Root User (System-Level)

Mitigation Strategy: Run as Non-Root User (System-Level)

Description:

  1. Create User: Create a dedicated, unprivileged user account on the system (e.g., sonicuser).
  2. Set Permissions: Ensure this user has the necessary permissions to access the Sonic data directory and configuration file.
  3. Run Service: Configure the system's service manager (e.g., systemd, init.d) to run the Sonic service under this unprivileged user account.

Threats Mitigated:

  • Privilege Escalation (High Severity): Limits the potential damage if Sonic is compromised.

Impact:

  • Privilege Escalation: Risk significantly reduced (from High to Low).

Currently Implemented:

  • Sonic is running as the sonicuser user account. The systemd service file (sonic.service) is configured correctly.

Missing Implementation:

  • None. This is fully implemented.
