由于ARP攻击是一种网络安全问题,设计一个完整的基于Linux的ARP攻击检测防护软件需要考虑多个因素,包括网络拓扑结构、攻击类型、防御策略等。以下是一个基本的Python代码实现,包括ARP攻击检测和IP/MAC地址扫描功能。

import os
import sys
import time
import socket
import struct
import fcntl
import threading

# 定义常量
ETHERNET_PROTOCOL_ARP = 0x0806
ARP_REQUEST = 1
ARP_REPLY = 2

# 定义全局变量
local_ip = ''
local_mac = ''
ip_mac_dict = {}
arp_dict = {}

# 获取本地IP地址和MAC地址
def get_local_ip_mac():
    global local_ip, local_mac
    s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    s.connect(('8.8.8.8', 80))
    local_ip = s.getsockname()[0]
    s.close()
    with open('/sys/class/net/eth0/address') as f:
        local_mac = f.read().strip()

# 发送ARP请求
def send_arp_request(target_ip):
    global local_ip, local_mac
    s = socket.socket(socket.AF_PACKET, socket.SOCK_RAW, socket.htons(ETHERNET_PROTOCOL_ARP))
    s.bind(('eth0', ETHERNET_PROTOCOL_ARP))
    target_mac = 'ff:ff:ff:ff:ff:ff'
    arp_packet = struct.pack('!6s6sHHHBBH6s4s6s4s', 
        target_mac, local_mac, ETHERNET_PROTOCOL_ARP, 
        ARP_REQUEST, 0x0800, 0x06, 0x04, ARP_REQUEST, 
        local_mac, socket.inet_aton(local_ip), 
        target_mac, socket.inet_aton(target_ip))
    s.send(arp_packet)
    s.close()

# 处理ARP响应
def handle_arp_reply(packet):
    global ip_mac_dict
    source_mac = packet[6:12]
    source_ip = socket.inet_ntoa(packet[28:32])
    ip_mac_dict[source_ip] = source_mac

# 监听ARP包
def listen_arp_packet():
    global arp_dict
    s = socket.socket(socket.AF_PACKET, socket.SOCK_RAW, socket.htons(ETHERNET_PROTOCOL_ARP))
    s.bind(('eth0', ETHERNET_PROTOCOL_ARP))
    while True:
        packet = s.recvfrom(2048)[0]
        if packet[12:14] == '\x08\x06':
            arp_operation = struct.unpack('!HHBBH6s4s6s4s', packet[14:42])[3]
            if arp_operation == ARP_REPLY:
                handle_arp_reply(packet)
        time.sleep(0.1)

# 扫描局域网内的IP和MAC地址
def scan_ip_mac():
    global ip_mac_dict
    for i in range(1, 255):
        target_ip = '192.168.1.%d' % i
        if target_ip != local_ip:
            send_arp_request(target_ip)
    time.sleep(5)
    arp_dict = ip_mac_dict.copy()
    ip_mac_dict.clear()

# 检测ARP攻击
def detect_arp_attack():
    global arp_dict
    while True:
        for ip, mac in arp_dict.items():
            if mac != ip_mac_dict.get(ip):
                print('ARP SPOOFING ATTACK DETECTED: %s' % ip)
        time.sleep(1)

# 主程序
if __name__ == '__main__':
    get_local_ip_mac()
    print('Local IP: %s' % local_ip)
    print('Local MAC: %s' % local_mac)
    t1 = threading.Thread(target=listen_arp_packet)
    t2 = threading.Thread(target=detect_arp_attack)
    t1.start()
    t2.start()
    while True:
        scan_ip_mac()
