为了方便平时定期web服务器安全日志分析，闲暇时写了个小脚本，支持自动scp远程web服务器日志到本地，然后多线程安全分析，分析策略是软waf提取到正则，所以基本上目前主流的web攻击行为，sql注入、xss、扫描器扫描、webshell、目录遍历之类都可以配合分析。
软waf策略参考：https://github.com/loveshell/ngx_lua_waf/tree/master/wafconf
脚本如下：
#!/usr/bin/python
# -*- coding: utf-8 -*-
import os
import re
from multiprocessing.dummy import Pool as ThreadPool
import sys
import time
import pexpect
# 规则列表
rulelist = ['\.\./', 'select.+(from|limit)', '(?:(union(.*?)select))', 'having|rongjitest', 'sleep\((\s*)(\d*)(\s*)\)',

]
for line in cmd:

效果如下：
