SSH Connection Monitoring Service

Users of the center can apply to this service to have daily e-mails sent to username@hgc.jp with the SSH connection status (date and time of accesses to the gateway server, connection source host, connection result) of the registered user account. After registering, the user can log in to the below URL and define a white list.
  https://supcom.hgc.jp/internal/cgi/login.cgi

Should the applicant be someone other than the registered user account holder, the applicant must log in using the registered user account.

File Access Limit Monitoring Service

Users of the center can apply to this service to have their home directory scanned for files with a permission bit set for group or other, and have a list of those files send to username@hgc.jp.
Use this service to improve your home directory’s security by seeing which files can be accessed by other users.
