网络安全测试是确保应用程序和系统安全的重要环节。Python 作为一种强大的编程语言,在网络安全测试中扮演着重要角色。本文将详细介绍 Python 网络安全测试的 6 个关键步骤,并通过具体的代码示例帮助你更好地理解和应用这些技术。
首先,你需要确保你的开发环境已经准备好。安装 Python 和一些常用的网络安全库是必不可少的步骤。
# 安装 Python sudo apt-get install python3 # 安装 pip sudo apt-get install python3-pip # 安装常用的网络安全库 pip3 install requests beautifulsoup4 scapy1.2.3.4.5.6.7.8.
使用 requests 库可以轻松发送 HTTP 请求,这是网络安全测试的基础。
import requests # 发送 GET 请求 response = requests.get('https://example.com')print(response.status_code) # 输出状态码print(response.text) # 输出响应内容 # 发送 POST 请求 data = {'key': 'value'}response = requests.post('https://example.com', data=data)print(response.status_code) # 输出状态码print(response.text) # 输出响应内容1.2.3.4.5.6.7.8.9.10.11.12.
在处理响应数据时,BeautifulSoup 是一个非常有用的库,可以帮助你解析 HTML 和 XML 文档。
from bs4 import BeautifulSoup html_content = '''<html><head><title>Example Page</title></head><body><h1>Welcome to Example Page</h1><p>This is a sample paragraph.</p></body></html>''' # 解析 HTML 内容 soup = BeautifulSoup(html_content, 'html.parser')# 提取标题 title = soup.title.stringprint(title) # 输出: Example Page # 提取所有段落 paragraphs = soup.find_all('p')for p in paragraphs: print(p.text) # 输出: This is a sample paragraph.1.2.3.4.5.6.7.8.9.10.11.12.13.14.15.16.17.18.19.20.21.22.23.
使用 scapy 库可以进行网络扫描,检测网络中的主机和服务。
from scapy.all import # 发送 ARP 请求,扫描局域网内的主机 def scan_network(ip_range): arp_request = ARP(pdst=ip_range) broadcast = Ether(dst="ff:ff:ff:ff:ff:ff") arp_request_broadcast = broadcast / arp_request answered_list = srp(arp_request_broadcast, timeout=1, verbose=False)[0] clients_list = [] for element in answered_list: client_dict = {"ip": element[1].psrc, "mac": element[1].hwsrc} clients_list.append(client_dict) return clients_list # 扫描 192.168.1.1/24 网段 clients = scan_network("192.168.1.1/24")for client in clients: print(f"IP: {client['ip']}, MAC: {client['mac']}")1.2.3.4.5.6.7.8.9.10.11.12.13.14.15.16.17.18.19.20.
使用 requests 库可以检测常见的 Web 漏洞,如 SQL 注入和 XSS 攻击。
# 检测 SQL 注入 def test_sql_injection(url): payloads = ["' OR '1'='1", "' OR '1'='1' --", "' OR '1'='1' /"] for payload in payloads: response = requests.get(f"{url}?username={payload}") if "Welcome" in response.text: print(f"Potential SQL Injection vulnerability found with payload: {payload}")# 检测 XSS 攻击 def test_xss(url): payloads = ["<script>alert('XSS')</script>", "<img src=x onerror=alert('XSS')>"] for payload in payloads: response = requests.get(f"{url}?comment={payload}") if payload in response.text: print(f"Potential XSS vulnerability found with payload: {payload}")# 测试 URLtest_sql_injection("http://example.com/login")test_xss("http://example.com/comment")1.2.3.4.5.6.7.8.9.10.11.12.13.14.15.16.17.18.19.
最后,生成详细的测试报告是非常重要的。你可以使用 reportlab 库生成 PDF 报告。
from reportlab.lib.pagesizes import letter from reportlab.pdfgen import canvas def generate_report(filename, title, content): c = canvas.Canvas(filename, pagesize=letter) width, height = letter c.drawString(100, height - 100, title) y = height - 150 for line in content.split('\n'): c.drawString(100, y, line) y -= 20 c.save()# 生成报告 report_content = """ Vulnerability Report--------------------- Potential SQL Injection vulnerability found with payload: ' OR '1'='1- Potential XSS vulnerability found with payload: <script>alert('XSS')</script>"""generate_report("vulnerability_report.pdf", "Security Test Report", report_content)1.2.3.4.5.6.7.8.9.10.11.12.13.14.15.16.17.18.19.20.21.22.23.
假设你正在为一个电商网站进行安全测试。你需要检查以下几点:
HTTP 请求:确保网站支持 HTTPS。
数据解析:提取网站的关键信息,如商品列表。
网络扫描:扫描服务器的开放端口。
漏洞检测:检测 SQL 注入和 XSS 攻击。
报告生成:生成详细的测试报告。
import requests from bs4 import BeautifulSoup from scapy.all import from reportlab.lib.pagesizes import letter from reportlab.pdfgen import canvas # 1. HTTP 请求 url = "https://example.com"response = requests.get(url)if not response.url.startswith("https"): print("Warning: The website does not support HTTPS.")# 2. 数据解析 soup = BeautifulSoup(response.text, 'html.parser')products = soup.find_all('div', class_='product')for product in products: name = product.find('h2').text price = product.find('span', class_='price').text print(f"Product: {name}, Price: {price}")# 3. 网络扫描 def scan_network(ip_range): arp_request = ARP(pdst=ip_range) broadcast = Ether(dst="ff:ff:ff:ff:ff:ff") arp_request_broadcast = broadcast / arp_request answered_list = srp(arp_request_broadcast, timeout=1, verbose=False)[0] clients_list = [] for element in answered_list: client_dict = {"ip": element[1].psrc, "mac": element[1].hwsrc} clients_list.append(client_dict) return clients_list clients = scan_network("192.168.1.1/24")for client in clients: print(f"IP: {client['ip']}, MAC: {client['mac']}")# 4. 漏洞检测 def test_sql_injection(url): payloads = ["' OR '1'='1", "' OR '1'='1' --", "' OR '1'='1' /"] for payload in payloads: response = requests.get(f"{url}/search?query={payload}") if "Welcome" in response.text: print(f"Potential SQL Injection vulnerability found with payload: {payload}")def test_xss(url): payloads = ["<script>alert('XSS')</script>", "<img src=x onerror=alert('XSS')>"] for payload in payloads: response = requests.get(f"{url}/comment?text={payload}") if payload in response.text: print(f"Potential XSS vulnerability found with payload: {payload}")test_sql_injection(url)test_xss(url)# 5. 报告生成 report_content = """ Vulnerability Report--------------------- Website does not support HTTPS.- Products found: - Product: Example Product, Price: $10.99- Network Scan Results: - IP: 192.168.1.1, MAC: 00:1A:2B:3C:4D:5E- Potential SQL Injection vulnerability found with payload: ' OR '1'='1- Potential XSS vulnerability found with payload: <script>alert('XSS')</script>"""generate_report("vulnerability_report.pdf", "Security Test Report", report_content)1.2.3.4.5.6.7.8.9.10.11.12.13.14.15.16.17.18.19.20.21.22.23.24.25.26.27.28.29.30.31.32.33.34.35.36.37.38.39.40.41.42.43.44.45.46.47.48.49.50.51.52.53.54.55.56.57.58.59.60.61.62.63.64.65.66.67.68.69.
