Achieve improved network programmability and automation by leveraging powerful network programming concepts, algorithms, and tools

Key Features

• Deal with remote network servers using SSH, FTP, SNMP and LDAP protocols.
• Design multi threaded and event-driven architectures for asynchronous servers programming.
• Leverage your Python programming skills to build powerful network applications

Book Description

Network programming has always been a demanding task. With full-featured and well-documented libraries all the way up the stack, Python makes network programming the enjoyable experience it should be.

Starting with a walk through of today's major networking protocols, through this book, you'll learn how to employ Python for network programming, how to request and retrieve web resources, and how to extract data in major formats over the web. You will utilize Python for emailing using different protocols, and you'll interact with remote systems and IP and DNS networking. You will cover the connection of networking devices and configuration using Python 3.7, along with cloud-based network management tasks using Python.

As the book progresses, socket programming will be covered, followed by how to design servers, and the pros and cons of multithreaded and event-driven architectures. You'll develop practical clientside applications, including web API clients, email clients, SSH, and FTP. These applications will also be implemented through existing web application frameworks.

What you will learn

• Execute Python modules on networking tools
• Automate tasks regarding the analysis and extraction of information from a network
• Get to grips with asynchronous programming modules available in Python
• Get to grips with IP address manipulation modules using Python programming
• Understand the main frameworks available in Python that are focused on web application
• Manipulate IP addresses and perform CIDR calculations

Master Python scripting to build a network and perform security operations

Key Features

• Learn to handle cyber attacks with modern Python scripting
• Discover various Python libraries for building and securing your network
• Understand Python packages and libraries to secure your network infrastructure

Book Description

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.

What you will learn

• Develop Python scripts for automating security and pentesting tasks
• Discover the Python standard library's main modules used for performing security-related tasks
• Automate analytical tasks and the extraction of information from servers
• Explore processes for detecting and exploiting vulnerabilities in servers
• Use network software for Python programming
• Perform server scripting and port scanning with Python
• Identify vulnerabilities in web applications with Python
• Use Python to extract metadata and forensics

Who this book is for

This book is ideal for network engineers, system administrators, or any security professional looking at tackling networking and security challenges. Programmers with some prior experience in Python will get the most out of this book. Some basic understanding of general programming structures and Python is required.
