多线程WEB安全日志分析脚本

16-08-08

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。

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:
        child = pexpect.spawn(line,timeout=300)
        child.expect('password:')
        child.sendline(SSH_PASSWD)
        child.expect(pexpect.EOF)
    return True
def File_Search(filepath):
    filelist = []
    for lists in os.listdir(filepath):
        path = os.path.join(filepath, lists)
        if os.path.isfile(path):
            filelist.append(path)
        if os.path.isdir(path):
            File_Search(path)
    pool = ThreadPool(50)
    results = pool.map(Log_Analysis, filelist)
    pool.close()
    pool.join()
def Log_Analysis(filename):
    content = open(filename).read()
    r = open('result.txt', 'a') #需要本地先新建个result.txt文件
    r.write('\n' + '=================== web_log_secAnalysis ===================' + '\n' + filename + '\n')
    for regex in rulelist:
        result_tmp = re.compile(regex,re.IGNORECASE).findall(content)
        if result_tmp:
            r.write(str(result_tmp) + '\n' )
    return 'True'
if __name__ == '__main__':
    if len(sys.argv)

        print "Usage: log_SecAnalysis.py filepath"
        sys.exit(0)
    else:
        if Auto_scp():
            start = time.clock()
            print '====> Log is analyzing, please wait for a moment
            File_Search(sys.argv[1])
            end = time.clock()
            print '分析完毕,共运行时长:' + str(end - start)
            sys.exit(0)
        else:
            print '文件scp传输异常...'
效果如下:
