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.

實戰案例#

示例一:自動檢測惡意 IP 並封鎖#

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"已封鎖惡意IP地址:{ip}")

# 模擬檢測IP並封鎖
check_ip("1.2.3.4")

示例二:自動更新防火牆規則#

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()} - 防火牆規則已更新")

# 定期執行防火牆規則更新
update_firewall_rules()

示例三:自動爬取漏洞信息並郵件通知#

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

def crawl_vulnerabilities():
    # 爬取漏洞信息的代碼,這裡省略具體實現
    vulnerabilities = get_vulnerabilities()
    send_email(vulnerabilities)

def send_email(vulnerabilities):
    msg = MIMEText(f"發現以下漏洞:\n{vulnerabilities}")
    msg['Subject'] = '網絡漏洞通知'
    msg['From'] = '[email protected]'
    msg['To'] = '[email protected]'

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

# 定時執行漏洞爬取並郵件通知
crawl_vulnerabilities()

總結#

本文通過實戰案例給出了三種用 Python 實現自動化網絡防禦的示例,包括自動檢測惡意 IP 並封鎖、自動更新防火牆規則以及自動爬取漏洞信息並郵件通知。這些實例展示了 Python 在網絡安全領域的強大應用能力,可以大大提高網絡安全防禦的效果。
