RUGGEDCOM ROX Chapter 3 User Guide Device Management Section 3.7.9.2 Enabling Secure Remote Syslog Figure 60: Secure Remote Syslog Settings ROX supports the encryption of system logs with rsyslog. NOTE All certificates must be conform to the following specifications: • X.509 v3 digital certificate format • PEM format • RSA key pair, 512 to 2048 bits in length NOTE Once secure remote system logging is enabled and a remote syslog server is configured, TCP port 6514 is automatically opened. Enable enables or disables secure remote syslog. CA certificate specifies the path and filename of a CA (Certified Authority) certificate. The client and server certificates must by signed by the same Certified Authority (CA). Certificate specifies the path and filename of a certificate. Key specifies the path and filename of a key. Permitted Peer Common Name allows you to match the common name in the certificate with one or more match patterns. Each match pattern must be separated by a space. The default value is "pattern", which can be replaced by one or more patterns, which can include wildcards (*). For example, the match pattern "*.example.com" will match "abc.example.com". Alternatively, the match pattern "a* *.example.com" will also match "abc.example.com", but it will not match "abc.example". CAUTION! Security hazard - risk of unauthorized access or exploitation. Selecting the Do not check radio button configures ROX to accept a certificate with any common name from the server. This mode is vulnerable to man-in-the-middle attacks and is not recommended. If you do not want to match the common name, select the Do not check radio button. Enabling Secure Remote Syslog 59
