Today im going to show how to configure Fail2ban on Centos 7 and block SSH attempts.

Install Fail2ban on CentOS 7


# sudo yum install epel-release

# yum install fail2ban

# systemctl enable fail2ban




Configure Local Settings


# nano /etc/fail2ban/jail.local




Paste the following:
/etc/fail2ban/jail.local
[DEFAULT]
# Ban hosts for one hour:
bantime = 3600

# Override /etc/fail2ban/jail.d/00-firewalld.conf:
banaction = iptables-multiport

[sshd]
enabled = true
# sudo systemctl restart fail2ban

# fail2ban-client status sshd
