The book is intended for those who want to know more about network penetration tests and have no prior experience, as well as for those who are experienced in network systems and are curious to discover more about this topic. Since zANTI2 features an extremely intuitive and easy to control interface, it doesn't require any special skills.What You Will LearnUnderstand the importance of penetration testing throughout systemsTake a run through zANTI2's interface and understand the requirements to the appPerform advanced scanning/network mapping and discover the various types of scans used on a targetDiscover and remotely connect to open ports on a target, thereby accessing a target's files and folders remotelyDetect vulnerabilities on a target, learn how to remotely exploit them, and discover ways to protect your self from these exploitsUnderstand what an MITM attack is and how it works, and apply this knowledge to perform attacks on network targetsLearn to hijack sessions, identify victim's passwords, replace images on websites, inject scripts, and moreUse this knowledge to protect yourself from all of the attacks you will studyIn Detail
A penetration test is one of the most important methods to secure a network or any individual machine. Having knowledge of these methods can enable a user to protect himself/herself from any kinds of attacks. Penetration tests can also be used to discover flaws or loop holes in one's security system, which if not fixed, can be exploited by an unwanted entity.
This book starts off with an introduction to what penetration testing is, and how it can be performed on Android using zANTI2. Once you are aware of the basics, we move on to teach you the different types of scans that can be performed to search for targets. You will then learn how to connect to open ports and intrude into an unsecured computer. From here you will explore vulnerabilities and their usage, including ShellShock and SSL Poodle vulnerability.
When connected to an open network, a user is susceptible to password and session hijacking, and a number of other cyber attacks. The book therefore ends with one of the main aspects of cyber security: the Man in the Middle attack. You will get to know everything about the MITM attack, how it works, and how one can be protected against it.Style and approach
The book follows a step-by-step approach with each of the parts explained in an easy-to-follow style. Most of the methods showcased can be tried out immediately on almost any network.
If you are familiar with TCP/IP networking and general system administration, then this book is ideal for you. Some knowledge and understanding of core elements and applications related to Virtual Private Networking is assumed.What You Will LearnIdentify different VPN protocols (IPSec, PPTP, OpenVPN)Build your own PKI and manage certificatesDeploy your VPN on various devices like PCs, mobile phones, tablets, and moreDifferentiate between the routed and bridged networkEnhance your VPN with monitoring and loggingAuthenticate against third-party databases like LDAP or the Unix password fileTroubleshoot an OpenVPN setup that is not performing correctlyIn Detail
Security on the internet is increasingly vital to both businesses and individuals. Encrypting network traffic using Virtual Private Networks is one method to enhance security. The internet, corporate, and “free internet” networks grow more hostile every day. OpenVPN, the most widely used open source VPN package, allows you to create a secure network across these systems, keeping your private data secure. The main advantage of using OpenVPN is its portability, which allows it to be embedded into several systems.
This book is an advanced guide that will help you build secure Virtual Private Networks using OpenVPN. You will begin your journey with an exploration of OpenVPN, while discussing its modes of operation, its clients, its secret keys, and their format types. You will explore PKI: its setting up and working, PAM authentication, and MTU troubleshooting. Next, client-server mode is discussed, the most commonly used deployment model, and you will learn about the two modes of operation using "tun" and "tap" devices.
The book then progresses to more advanced concepts, such as deployment scenarios in tun devices which will include integration with back-end authentication, and securing your OpenVPN server using iptables, scripting, plugins, and using OpenVPN on mobile devices and networks.
Finally, you will discover the strengths and weaknesses of the current OpenVPN implementation, understand the future directions of OpenVPN, and delve into the troubleshooting techniques for OpenVPN.
By the end of the book, you will be able to build secure private networks across the internet and hostile networks with confidence.Style and approach
An easy-to-follow yet comprehensive guide to building secure Virtual Private Networks using OpenVPN. A progressively complex VPN design is developed with the help of examples. More advanced topics are covered in each chapter, with subjects grouped according to their complexity, as well as their utility.

This book introduces you to wireless penetration testing and describes how to conduct its various phases. After showing you how to install Kali Linux on your laptop, you will verify the requirements of the wireless adapter and configure it. Next, the book covers the wireless LAN reconnaissance phase, explains the WEP and WPA/WPA2 security protocols and demonstrates practical attacks against them using the tools provided in Kali Linux, Aircrack-ng in particular. You will then discover the advanced and latest attacks targeting access points and wireless clients and learn how to create a professionally written and effective report.
It's also likely that at some point, you'll have to break up one large network into a number of smaller ones because user response has decresed to a trickle as the network grew and grew and LAN traffic congestion reached overwhelming proportions. Breaking up a larger network into a number of smaller ones is called network segmentation, and it's accomplished using routers, switches, and bridges.
The reason for this book is to help you with your Cisco certification by covering the essentials you need in order to pass the CCNA exams.
Security Monitoring is based on the authors' years of experience conducting incident response to keep Cisco's global network secure. It offers six steps to improve network monitoring. These steps will help you:
Develop Policies: define rules, regulations, and monitoring criteriaKnow Your Network: build knowledge of your infrastructure with network telemetrySelect Your Targets: define the subset of infrastructure to be monitoredChoose Event Sources: identify event types needed to discover policy violationsFeed and Tune: collect data, generate alerts, and tune systems using contextual informationMaintain Dependable Event Sources: prevent critical gaps in collecting and monitoring events
Security Monitoring illustrates these steps with detailed examples that will help you learn to select and deploy the best techniques for monitoring your own enterprise network.
