A system administrator is hardening an SSH server using fail2ban. They want to configure it to ban an IP address for one full day after 5 failed login attempts within a 15-minute window. Which of the following configurations in /etc/fail2ban/jail.local would correctly implement this policy for the sshd jail?

  • [sshd]
    enabled = true
    maxretry = 5
    findtime = 15m
    bantime = 1d
    
  • [sshd]
    enabled = true
    bantime = 5
    findtime = 1d
    maxretry = 15
    
  • [DEFAULT]
    maxretry = 5
    findtime = 900
    bantime = 86400
