一 点睛

本次实践实现了一个集中式的病毒扫描管理,可以针对不同业务环境定制扫描策略,比如扫描对象、描述模式、扫描路径、调度频率等。案例实现的架构图如下,首先业务服务器开启clamd服务(监听3310端口),管理服务器启用多线程对指定的服务集群进行扫描,扫描模式、扫描路径会传递到clamd,最后返回扫描结果给管理服务器端。

本次实战通过ClamdNetworkSocket()方法实现与业务服务器建立扫描socket连接,再通过启动不同扫描方式实施病毒扫描并返回结果。

二 代码

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import time
import pyclamd
from threading import Thread

class Scan(Thread):

    def __init__ (self,IP,scan_type,file):
        """构造方法"""
        Thread.__init__(self)
        self.IP = IP
        self.scan_type=scan_type
        self.file = file
        self.connstr=""
        self.scanresult=""


    def run(self):
        """多进程run方法"""

        try:
            cd = pyclamd.ClamdNetworkSocket(self.IP,3310)
            if cd.ping():
                self.connstr=self.IP+" connection [OK]"
                cd.reload()
                if self.scan_type=="contscan_file":
                    self.scanresult="{0}\n".format(cd.contscan_file(self.file))
                elif self.scan_type=="multiscan_file":
                    self.scanresult="{0}\n".format(cd.multiscan_file(self.file))
                elif self.scan_type=="scan_file":
                    self.scanresult="{0}\n".format(cd.scan_file(self.file))
                time.sleep(1)
            else:
                self.connstr=self.IP+" ping error,exit"
                return
        except Exception,e:
            self.connstr=self.IP+" "+str(e)


IPs=['192.168.0.120']
scantype="multiscan_file"
scanfile="/data"
i=1
threadnum=2
scanlist = []

for ip in IPs:

    currp = Scan(ip,scantype,scanfile)
    scanlist.append(currp)

    if i%threadnum==0 or i==len(IPs):
        for task in scanlist:
            task.start()

        for task in scanlist:
            task.join()
            print task.connstr
            print task.scanresult
        scanlist = []
    i+=1

三 结果

1 无病毒的情况下,扫描结果

E:\Python\python_auto_maintain\venv\Scripts\python.exe E:/Python/python_auto_maintain/4_1_2.py
192.168.0.120 connection [OK]
None

2 有病毒的情况下,扫描结果

2.1 制作病毒测试文件

X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*

2.2 扫描结果

E:\Python\python_auto_maintain\venv\Scripts\python.exe E:/Python/python_auto_maintain/4_1_2.py
192.168.0.120 connection [OK]
{u'/data/EICAR': ('FOUND', 'Eicar-Test-Signature')}
