target = "example.com" 
for port in range(1, 100): 
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) 
if s.connect_ex((target, port)) == 0: 
print(f"Port {port} is open") 
s.close()

Git & GitHub Security

  • Check commit history for secrets: 
    git log -p | grep -i "password|key|token"
  • Enable 2FA on GitHub for better security.
