网络安全技术代码分享
网络安全技术主要是为了保护网络中的数据和系统免受黑客、病毒和其他恶意攻击的影响。下面是一些常见的网络安全技术代码分享:
1. 防火墙设置代码:
```python
import iptc
def set_firewall_rules():
table = iptc.Table(iptc.Table.FILTER)
chain = iptc.Chain(table, "INPUT")
rule = iptc.Rule()
rule.in_interface = "eth0"
rule.src = "192.168.0.0/24"
rule.protocol = "tcp"
rule.target = iptc.Target(rule, "ACCEPT")
p_flags = "SYN,ACK"
match = iptc.Match(rule, "tcp")
match.dport = "22"
rule.add_match(match)
chain.insert_rule(rule)
```
2. 数据加密代码:
```python
import hashlib
import base64
def encrypt_data(data, password):
key = hashlib.de()).digest()
字母大小写转换公式 iv = b'0000000000000000'
cipher = w(key, AES.MODE_CBC, iv)
padded_data = data + (AES.block_size - len(data) % AES.block_size) * ' '
encrypted_data = pt(padded_data)

return base64.b64encode(encrypted_data)

3. 多因素身份验证代码:
```python
import pyotp
def generate_otp(secret_key):
totp = pyotp.TOTP(secret_key)
w()
def validate_otp(otp, secret_key):
totp = pyotp.TOTP(secret_key)
return totp.verify(otp)
```
4. CSRF防护代码:
```python
from flask import Flask, session, request, render_template_string
app = Flask(__name__)
app.secret_key = 'secret_key'
@ute('/')
def index():
token = ('token')
return render_template_string('<input type="hidden" name="csrf_token" value="{{ token }}">')
@ute('/login', methods=['POST'])
def login():
csrf_token = ('csrf_token')
if csrf_token == ('token'):
return 'Login success'
else:
return 'CSRF attack detected!'
if __name__ == '__main__':

```
5. DDos攻击防护代码:
```python
import sys
import threading
import socket
HOST = 'localhost'
PORT = 8080
织梦cms开始收费MAX_BYTES = 65535
jvm官方下载def send_request():
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
t((HOST, PORT))
message = "GET / HTTP/1.1\r\nHost: localhost\r\n\r\n"
sock.de())
sock.close()
def start_attack(threads):
for i in range(threads):
threading.Thread(target=send_request).start()
if __name__ == '__main__':
threads = int(sys.argv[1])
start_attack(threads)
```
以上是一些常见的网络安全技术代码分享,可以用于保护网络安全。当然,在实际应用中,还需要根据具体场景和需求进行适当的修改和扩展。
