Book Description
Set up next-generation firewalls from Palo Alto Networks and get to grips with configuring and troubleshooting using the PAN-OS platform Key FeaturesUnderstand how to optimally use PAN-OS featuresBuild firewall solutions to safeguard local, cloud, and mobile networksProtect your infrastructure and users by implementing robust threat prevention solutionsBook Description To safeguard against security threats, it is crucial to ensure that your organization is effectively secured across networks, mobile devices, and the cloud. Palo Alto Networks' integrated platform makes it easy to manage network and cloud security along with endpoint protection and a wide range of security services. With this book, you'll understand Palo Alto Networks and learn how to implement essential techniques, right from deploying firewalls through to advanced troubleshooting. The book starts by showing you how to set up and configure the Palo Alto Networks firewall, helping you to understand the technology and appreciate the simple, yet powerful, PAN-OS platform. Once you've explored the web interface and command-line structure, you'll be able to predict expected behavior and troubleshoot anomalies with confidence. You'll learn why and how to create strong security policies and discover how the firewall protects against encrypted threats. In addition to this, you'll get to grips with identifying users and controlling access to your network with user IDs and even prioritize traffic using quality of service (QoS). The book will show you how to enable special modes on the firewall for shared environments and extend security capabilities to smaller locations. By the end of this network security book, you'll be well-versed with advanced troubleshooting techniques and best practices recommended by an experienced security engineer and Palo Alto Networks expert. What you will learnPerform administrative tasks using the web interface and command-line interface (CLI)Explore the core technologies that will help you boost your network securityDiscover best practices and considerations for configuring security policiesRun and interpret troubleshooting and debugging commandsManage firewalls through Panorama to reduce administrative workloadsProtect your network from malicious traffic via threat preventionWho this book is for This book is for network engineers, network security analysts, and security professionals who want to understand and deploy Palo Alto Networks in their infrastructure. Anyone looking for in-depth knowledge of Palo Alto Network technologies, including those who currently use Palo Alto Network products, will find this book useful.

Linux Firewalls
Author: Michael Rash
Publisher: No Starch Press
ISBN: 1593271417
Category : Computers
Languages : en
Pages : 338
Book Description
System administrators need to stay ahead of new security vulnerabilities that leave their networks exposed every day. A firewall and an intrusion detection systems (IDS) are two important weapons in that fight, enabling you to proactively deny access and monitor network traffic for signs of an attack. Linux Firewalls discusses the technical details of the iptables firewall and the Netfilter framework that are built into the Linux kernel, and it explains how they provide strong filtering, Network Address Translation (NAT), state tracking, and application layer inspection capabilities that rival many commercial tools. You'll learn how to deploy iptables as an IDS with psad and fwsnort and how to build a strong, passive authentication layer around iptables with fwknop. Concrete examples illustrate concepts such as firewall log analysis and policies, passive network authentication and authorization, exploit packet traces, Snort ruleset emulation, and more with coverage of these topics: –Passive network authentication and OS fingerprinting –iptables log analysis and policies –Application layer attack detection with the iptables string match extension –Building an iptables ruleset that emulates a Snort ruleset –Port knocking vs. Single Packet Authorization (SPA) –Tools for visualizing iptables logs Perl and C code snippets offer practical examples that will help you to maximize your deployment of Linux firewalls. If you're responsible for keeping a network secure, you'll find Linux Firewalls invaluable in your attempt to understand attacks and use iptables—along with psad and fwsnort—to detect and even prevent compromises.

Pages : 386
Book Description
‘Readers will come away startled at just how fragile the online infrastructure we all depend on is and how much influence China wields – both technically and politically' – Jason Q. Ng, author of Blocked on Weibo 'An urgent and much needed reminder about how China's quest for cyber sovereignty is undermining global Internet freedom’ – Kristie Lu Stout, CNN ‘An important and incisive history of the Chinese internet that introduces us to the government officials, business leaders, and technology activists struggling over access to information within the Great Firewall’ – Adam M. Segal, author of The Hacked World Order Once little more than a glorified porn filter, China’s ‘Great Firewall’ has evolved into the most sophisticated system of online censorship in the world. As the Chinese internet grows and online businesses thrive, speech is controlled, dissent quashed, and attempts to organise outside the official Communist Party are quickly stamped out. But the effects of the Great Firewall are not confined to China itself. Through years of investigation James Griffiths gained unprecedented access to the Great Firewall and the politicians, tech leaders, dissidents and hackers whose lives revolve around it. As distortion, post-truth and fake news become old news James Griffiths shows just how far the Great Firewall has spread. Now is the time for a radical new vision of online liberty.
