You should block those IPs using firewall.
  • You should constantly monitor the log, and append your block list with the new IPs that attacks.
  • Or allow only the IPs that are expected.
You should have strong password for root login, if that is ssh attack. Or even you can think about locking the root account, and use some sudo account to do the administration and be in the safer side.

NAME
init_policy - initialize TOMOYO Linux policy SYNOPSIS
init_policy [option] DESCRIPTION
This program generates templates for all policy files. However, the output should be reviewed because automatically generated exception policy may contain dangerous or redundant entries. This program only needs to be run once. OPTIONS
--file-only-profile Create profiles with only file-related functionality enabled. --full-profile Create profiles with all functionality enabled. [default] --use_profile=integer Set the default profile number for the "<kernel>" domain to the specified integer, which must be between 0 and 255. [default=0] --use_group=integer Set the default group number for the "<kernel>" domain to the specified integer, which must be between 0 and 255. [default=0] --max_audit_log=integer Set the default maximal audit log entries that the kernel will spool in the /sys/kernel/security/tomoyo/audit interface. This value must be an integer, and can be set to 0 if audit logs are not required. Maximum memory used can also be controlled via the /sys/kernel/security/tomoyo/stat interface. [default=1024] --max_learning_entry=integer Set the default maximum number of ACL entries automatically added to each domain by the kernel when using learning mode. This value must be an integer, and can be set to o if you do not need learning mode. Maximum memory used can also be controlled using the /sys/kernel/security/tomoyo/stat interface. --grant_log=value Set whether grant logs should be audited. This value can either be "yes" or "no". [default=no] --reject_log=value Set whether reject logs should be audited. This value can either be "yes" or "no". [default=yes] EXAMPLES
