一言不合就屏蔽，Fail2ban 防止 WordPress 穷举
一次密码错误就屏蔽 IP，不过如果攻击者每试一次都换一个 IP，那就不知道怎么办了。
新建一个 WordPress 规则：
|
1 2 3 4 5 6 7 8 9 10 |
# WordPress brute force auth filter: /etc/fail2ban/filter.d/wp-auth.conf: # # Block IPs trying to auth wp wordpress # # Matches e.g. # 12.34.33.22 - [07/Jun/2014:11:15:29] "POST /wp/wp-login.php HTTP/1.0" 200 4523 # [Definition] failregex = ^<HOST> .* "POST /wp-login.php ignoreregex = |
然后加入执行限制：
|
1 2 3 4 5 6 7 8 |
[wp-auth] enabled = true filter = wordpress port = http,https,333 action = iptables-multiport[name=NoAuthFailures, port="http,https"] logpath = /home/wwwlogs/*.log bantime = 60 maxretry = 1 |
为了避免把自己坑了，60 秒就够了。
