However, the sshd server is still vulnerable to a Denial of Service if an attacker exhausts all the connections.\n\n1) As root user, open the /etc/ssh/sshd_config\n2) Add or edit the parameter configuration:\n~~~\nLoginGraceTime 0\n~~~\n3) Save and close the file\n4) Restart the sshd daemon:\n~~~\nsystemctl restart sshd.service\n~~~\n\nSetting LoginGraceTime to 0 disables the SSHD server\u0027s ability to drop connections if authentication is not completed within the specified timeout. If this mitigation is implemented, it is highly recommended to use a tool like \u0027fail2ban\u0027 alongside a firewall to monitor log files and manage connections appropriately.\n\nIf any of the mitigations mentioned above is used, please note that the removal of LoginGraceTime parameter from sshd_config is not automatic when the updated package is installed."
