Know how to set up, defend, and attack computer networks with this revised and expanded second edition.

You will learn to configure your network from the ground up, beginning with developing your own private virtual test environment, then setting up your own DNS server and AD infrastructure. You will continue with more advanced network services, web servers, and database servers and you will end by building your own web applications servers, including WordPress and Joomla!. Systems from 2011 through 2017 are covered, including Windows 7, Windows 8, Windows 10, Windows Server 2012, and Windows Server 2016 as well as a range of Linux distributions, including Ubuntu, CentOS, Mint, and OpenSUSE.

Key defensive techniques are integrated throughout and you will develop situational awareness of your network and build a complete defensive infrastructure, including log servers, network firewalls, web application firewalls, and intrusion detection systems.

Of course, you cannot truly understand how to defend a network if you do not know how to attack it, so you will attack your test systems in a variety of ways. You will learn about Metasploit, browser attacks, privilege escalation, pass-the-hash attacks, malware, man-in-the-middle attacks, database attacks, and web application attacks.

What You’ll Learn

• Construct a testing laboratory to experiment with software and attack techniques
• Build realistic networks that include active directory, file servers, databases, web servers, and web applications such as WordPress and Joomla!
• Manage networks remotely with tools, including PowerShell, WMI, and WinRM
• Use offensive tools such as Metasploit, Mimikatz, Veil, Burp Suite, and John the Ripper
• Exploit networks starting from malware and initial intrusion to privilege escalation through password cracking and persistence mechanisms
• Defend networks by developing operational awareness using auditd and Sysmon to analyze logs, and deploying defensive tools such as the Snort intrusion detection system, IPFire firewalls, and ModSecurity web application firewalls

What This Book Covers

Chapter 1 begins to explain basic DNS principles. It introduces essential names, for example,domain and zone, explaining the difference between them. It describes the iteration principle by which the DNS translates names to IP addresses. It presents a configuration of a resolver both for UNIX and for Windows. The end of the chapter explains name server principles and describes various name server types.
Chapter 2 is fully focused on the most basic DNS procedure, the DNS query. Through this procedure, the DNS translates names to IP addresses. In the very beginning, however, this chapter describes in detail the Resource Record structure. At the end of this chapter, many practical examples of DNS exchanges are listed.
Chapter 3 deals with other DNS procedures (DNS Extensions), i.e., DNS Update, DNS Notify, incremental zone transfer, negative caching, IPv6 Extensions, IPsec, and TSIG.
Chapter 4 talks about the DNS implementation. It is derived from its historical evolution. From the historical point of view, the oldest DNS implementation that is still sometimes used is BIND version 4. This implementation is very simple so it is suitable to describe basic principles with it. Next, the new generations of BIND are discussed followed by the Windows 2000 implementation.
Chapter 5 discusses the tools for debugging DNS such as nslookup, dnswalk, and dig, how to control a name server using the rndc program, and the common errors that might occur while configuring DNS.
Chapter 6 deals with the creation of DNS domains (domain delegation) and with the procedure of domain registration.

Who This Book Is For

Book Description:

Leverage existing free open source software to build an identity and access management (IAM) platform that can serve your organization for the long term. With the emergence of open standards and open source software, it’s now easier than ever to build and operate your own IAM stack.

The most common culprit of the largest hacks has been bad personal identification. In terms of bang for your buck, effective access control is the best investment you can make. Financially, it’s more valuable to prevent than to detect a security breach. That’s why Identity and Access Management (IAM) is a critical component of an organization’s security infrastructure. In the past, IAM software has been available only from large enterprise software vendors. Commercial IAM offerings are bundled as “suites” because IAM is not just one component. It’s a number of components working together, including web, authentication, authorization, cryptographic, and persistence services.

The book covers all project phases from managing requirements, implementation, testing and post production support. By the end of the book you’ll have a toolbox full of solutions and plenty of working examples. With these you’ll be able to build your own PMIS uniquely suited to your organization.

Book Description:

Linux can be configured as a networked workstation, a DNS server, a mail server, a firewall, a gateway router, and many other things. These are all part of administration tasks, hence network administration is one of the main tasks of Linux system administration. By knowing how to configure system network interfaces in a reliable and optimal manner, Linux administrators can deploy and configure several network services including file, web, mail, and servers while working in large enterprise environments.

Starting with a simple Linux router that passes traffic between two private networks, you will see how to enable NAT on the router in order to allow Internet access from the network, and will also enable DHCP on the network to ease configuration of client systems. You will then move on to configuring your own DNS server on your local network using bind9 and tying it into your DHCP server to allow automatic configuration of local hostnames. You will then future enable your network by setting up IPv6 via tunnel providers.

Moving on, we’ll configure Samba to centralize authentication for your network services; we will also configure Linux client to leverage it for authentication, and set up a RADIUS server that uses the directory server for authentication.

Toward the end, you will have a network with a number of services running on it, and will implement monitoring in order to detect problems as they occur.

What you will learn

• Route an IPv6 netblock to your local network
• Modify your named instance to support setting hostnames for your IPv6 addresses
• Use SSH for remote console access
• Configure NGINX with TLS
• Secure XMPP with TLS
• Leverage iptables6 to firewall your IPv6 traffic
• Configure Samba as an Active Directory compatible directory service

The non-technical handbook for cyber security risk management

Solving Cyber Risk distills a decade of research into a practical framework for cyber security. Blending statistical data and cost information with research into the culture, psychology, and business models of the hacker community, this book provides business executives, policy-makers, and individuals with a deeper understanding of existing future threats, and an action plan for safeguarding their organizations. Key Risk Indicators reveal vulnerabilities based on organization type, IT infrastructure and existing security measures, while expert discussion from leading cyber risk specialists details practical, real-world methods of risk reduction and mitigation.

By the nature of the business, your organization’s customer database is packed with highly sensitive information that is essentially hacker-bait, and even a minor flaw in security protocol could spell disaster. This book takes you deep into the cyber threat landscape to show you how to keep your data secure.

• Understand who is carrying out cyber-attacks, and why
• Identify your organization’s risk of attack and vulnerability to damage
• Learn the most cost-effective risk reduction measures
• Adopt a new cyber risk assessment and quantification framework based on techniques used by the insurance industry

By applying risk management principles to cyber security, non-technical leadership gains a greater understanding of the types of threat, level of threat, and level of investment needed to fortify the organization against attack. Just because you have not been hit does not mean your data is safe, and hackers rely on their targets’ complacence to help maximize their haul. Solving Cyber Risk gives you a concrete action plan for implementing top-notch preventative measures before you’re forced to implement damage control.
