Being towards death

Heed not to the tree-rustling and leaf-lashing rain, Why not stroll along, whistle and sing under its rein. Lighter and better suited than horses are straw sandals and a bamboo staff, Who's afraid? A palm-leaf plaited cape provides enough to misty weather in life sustain. A thorny spring breeze sobers up the spirit, I feel a slight chill, The setting sun over the mountain offers greetings still. Looking back over the bleak passage survived, The return in time Shall not be affected by windswept rain or shine.

实战案例#

示例一:自动检测恶意 IP 并封锁#

import subprocess

def check_ip(ip):
    result = subprocess.run(['whois', ip], capture_output=True, text=True)
    whois_data = result.stdout
    if "Bad IP" in whois_data:
        block_ip(ip)

def block_ip(ip):
    subprocess.run(['iptables', '-A', 'INPUT', '-s', ip, '-j', 'DROP'])
    print(f"已封锁恶意IP地址:{ip}")

# 模拟检测IP并封锁
check_ip("1.2.3.4")

示例二:自动更新防火墙规则#

import datetime
import subprocess

def update_firewall_rules():
    antivirus_servers = ["10.1.1.1", "10.1.1.2", "10.1.1.3"]
    for server in antivirus_servers:
        subprocess.run(['iptables', '-A', 'INPUT', '-s', server, '-j', 'ACCEPT'])
    
    print(f"{datetime.datetime.now()} - 防火墙规则已更新")

# 定期执行防火墙规则更新
update_firewall_rules()

示例三:自动爬取漏洞信息并邮件通知#

import requests
import smtplib
from email.mime.text import MIMEText

def crawl_vulnerabilities():
    # 爬取漏洞信息的代码,这里省略具体实现
    vulnerabilities = get_vulnerabilities()
    send_email(vulnerabilities)

def send_email(vulnerabilities):
    msg = MIMEText(f"发现以下漏洞:\n{vulnerabilities}")
    msg['Subject'] = '网络漏洞通知'
    msg['From'] = '[email protected]'
    msg['To'] = '[email protected]'

    server = smtplib.SMTP('smtp.example.com')
    server.send_message(msg)
    server.quit()

# 定时执行漏洞爬取并邮件通知
crawl_vulnerabilities()

总结#

本文通过实战案例给出了三种用 Python 实现自动化网络防御的示例,包括自动检测恶意 IP 并封锁、自动更新防火墙规则以及自动爬取漏洞信息并邮件通知。这些实例展示了 Python 在网络安全领域的强大应用能力,可以大大提高网络安全防御的效果。
