Security settings

Security Audit Logging Mode

Determine where to record or transmit the audit logs. The audit logs are sent to a syslog server.
When using the External/ExternalSecure modes and setting the port assignment to manual in

the Security Audit Server PortAssignment setting, you must also enter the address and port

number for the audit server in the Security Audit Server Address and Security Audit Server Port

settings.

Requires user role: AUDIT
Value space: <Off/Internal/External/ExternalSecure>

Off: No audit logging is performed.
Internal: The system records the audit logs to internal logs, and rotates logs when they are

full.
External: The system sends the audit logs to an external syslog server. The syslog server

must support UDP.
ExternalSecure: The system sends encrypted audit logs to an external syslog server that is

verified by a certificate in the Audit CA list. The Audit CA list file must be uploaded to the

codec using the web interface. The common_name parameter of a certificate in the CA list

must match the IP address of the syslog server, and the secure TCP server must be set up

to listen for secure (TLS) TCP Syslog messages.

Example:

Security Audit Logging Mode: Off

Security Audit OnError Action

Determine what happens when the connection to the syslog server is lost. This setting is only

relevant when Security Audit Logging Mode is set to ExternalSecure.

Requires user role: AUDIT
Value space: <Halt/Ignore>

Halt: If a halt condition is detected the system codec is rebooted and only the auditor is

allowed to operate the unit until the halt condition has passed. When the halt condition has

passed the audit logs are re-spooled to the syslog server. Halt conditions are: A network

breach (no physical link), no syslog server running (or incorrect address or port to the syslog

server), TLS authentication failed (if in use), local backup (re-spooling) log full.
Ignore: The system will continue its normal operation, and rotate internal logs when full.

When the connection is restored it will again send its audit logs to the syslog server.

Example:

Security Audit OnError Action: Ignore

Security Audit Server Address

The audit logs are sent to a syslog server. Enter the IP address of the syslog server. Only valid

IPv4 or IPv6 address formats are accepted. Host names are not supported. This setting is only

relevant when Security Audit Logging Mode is set to External or ExternalSecure.

Requires user role: AUDIT
Value space: <S: 0, 64>

Format: A valid IPv4 address or IPv6 address

Example:

Security Audit Server Address: ""

Security Audit Server Port

The audit logs are sent to a syslog server. Enter the port of the syslog server that the system

shall send its audit logs to. This setting is only relevant when Security Audit PortAssignment is

set to Manual.

Requires user role: AUDIT
Value space: <0..65535>

Range: Select a value from 0 to 65535.

Example:

Security Audit Server Port: 514

Security Audit Server PortAssignment

The audit logs are sent to a syslog server. You can define how the port number of the external

syslog server will be assigned. This setting is only relevant when Security Audit Logging

Mode is set to External or ExternalSecure. To see which port number is used you can check

the Security Audit Server Port status. Navigate to Configuration > System status on the web

interface or; if on a command line interface, run the command xStatus Security Audit Server

Port.

Requires user role: AUDIT
Value space: <Auto/Manual>

Auto: Will use UDP port number 514 when the Security Audit Logging Mode is set to

External. Will use TCP port number 6514 when the Security Audit Logging Mode is set to

ExternalSecure.
Manual: Will use the port value defined in the Security Audit Server Port setting.

Example:

Security Audit Server PortAssignment: Auto
