Book Description
The concept of a PKI (public key infrastructure) has been around for decades, but it is one strand of IT which has taken an extraordinarily long time to come to fruition within the mainstream. This is mostly because implementing a PKI is time consuming and difficult. Maintaining a PKI is equally time consuming and even more difficult within the real world of mergers and acquisitions against a backdrop of ever-changing technology. Many organisations simply give up and hand everything over to a third party who promises to manage everything on their behalf. This is generally not a good idea and simply delays the inevitability of failures and misunderstood complexity. This book explores all the aspects of implementing and maintaining a PKI that the other books on the subject seem to miss. It reflects decades of hard-won experience, not only in PKI, not only in IT, not only in electronics, but in business, government agencies and academia alike. The book also explores the existence of a PKI alongside other technologies, such as biometrics, and against an ever-changing world of development methodologies. This last point is particularly relevant at this time as we are in the middle of a quiet, but all encompassing revolution in this respect. Consequently, this is the one book on PKI that you have to have on your shelf, whether you be a company director, IT manager, government minister or teacher of IT. It is the book which fills in all the gaps left in the literature and treads paths which others fear to tread. You will enjoy it enormously if you are from an IT background.

Book Description
Over 40 recipes to help you set up and configure Linux networks About This Book Move beyond the basics of how a Linux machine works and gain a better understanding of Linux networks and their configuration Impress your peers by setting up and configuring a Linux server and its various network elements like a pro This is a hands-on solution guide to building, maintaining, and securing a network using Linux Who This Book Is For This book is targeted at Linux systems administrators who have a good basic understanding and some prior experience of how a Linux machine operates, but want to better understand how various network services function, how to set them up, and how to secure them. You should be familiar with how to set up a Linux server and how to install additional software on them. 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 In Detail 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. Style and approach This book is packed with practical recipes and a task-based approach that will walk you through building, maintaining, and securing a computer network using Linux.

Book Description
Network Performance Security: Testing and Analyzing Using Open Source and Low-Cost Tools gives mid-level IT engineers the practical tips and tricks they need to use the best open source or low cost tools available to harden their IT infrastructure. The book details how to use the tools and how to interpret them. Network Performance Security: Testing and Analyzing Using Open Source and Low-Cost Tools begins with an overview of best practices for testing security and performance across devices and the network. It then shows how to document assets—such as servers, switches, hypervisor hosts, routers, and firewalls—using publicly available tools for network inventory. The book explores security zoning the network, with an emphasis on isolated entry points for various classes of access. It shows how to use open source tools to test network configurations for malware attacks, DDoS, botnet, rootkit and worm attacks, and concludes with tactics on how to prepare and execute a mediation schedule of the who, what, where, when, and how, when an attack hits. Network security is a requirement for any modern IT infrastructure. Using Network Performance Security: Testing and Analyzing Using Open Source and Low-Cost Tools makes the network stronger by using a layered approach of practical advice and good testing practices. - Offers coherent, consistent guidance for those tasked with securing the network within an organization and ensuring that it is appropriately tested - Focuses on practical, real world implementation and testing - Employs a vetted "security testing by example" style to demonstrate best practices and minimize false positive testing - Gives practical advice for securing BYOD devices on the network, how to test and defend against internal threats, and how to continuously validate a firewall device, software, and configuration - Provides analysis in addition to step by step methodologies
