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：

	    return 'True'



	if __name__ == '__main__':



	    if len(sys.argv) < 2:



	        print "Usage: log_SecAnalysis.py filepath"



	        sys.exit(0)



	    else:

	            start = time.clock()



	            print '====> Log is analyzing, please wait for a moment <==== '

效果如下：
