Mastering Python for Networking and Security

By: José Ortega

Overview of this book

It’s becoming more and more apparent that security is a critical aspect of IT infrastructure. A data breach is a major security incident, usually carried out by just hacking a simple network line. Increasing your network’s security helps step up your defenses against cyber attacks. Meanwhile, Python is being used for increasingly advanced tasks, with the latest update introducing many new packages. This book focuses on leveraging these updated packages to build a secure network with the help of Python scripting. This book covers topics from building a network to the different procedures you need to follow to secure it. You’ll first be introduced to different packages and libraries, before moving on to different ways to build a network with the help of Python scripting. Later, you will learn how to check a network’s vulnerability using Python security scripting, and understand how to check vulnerabilities in your network. As you progress through the chapters, you will also learn how to achieve endpoint protection by leveraging Python packages along with writing forensic scripts. By the end of this book, you will be able to get the most out of the Python language to build secure and robust networks that are resilient to attacks.

Chapter 7: Interacting with FTP, SSH, and SNMP Servers

  1. How do we connect to an FTP server using the ftplib module through the connect() and login() methods?

ftp = FTP()
ftp.connect(host, 21)
ftp.login(‘user’, ‘password’)

  1. What method of the ftplib module allows it to list the files of an FTP server?

FTP.dir()

  1. Which method of the Paramiko module allows us to connect to an SSH server and with what parameters (host, username, password)?

ssh = paramiko.SSHClient()
ssh.connect(host, username=’username’, password=’password’)

  1. Which method of the Paramiko module allows us to open a session to be able to execute commands subsequently?

ssh_session = client.get_transport().open_session()

  1. How do we log in to an SSH server with an RSA certificate from which we've found out the route and password?

rsa_key= RSAKey...
