H. Security Specifications
H. Security Specifications
This appendix describes the following items related to the security specifications:
• List of log capacities
• Security function list
H.1 List of log capacities
Log files, which are stored in /var/log, are important for finding signs of security attacks or for investigating
security accidents. There is a limit on the amount of log data that can be stored in CE50-10. Due to these
specifications, log files are automatically deleted after a certain period has passed after the log data is generated.
Table H‒1: Log file retention period list shows the standard retention period of log files generated by the OS and RAS
function of the CE50-10. If necessary, consider copying log files to external media before they are deleted. For some
log files, the retention period might change depending on how they are used. For such log files, the prerequisite
specification conditions for the retention period are also described.
