Overview of this book

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.

Special case for upgrading older hardware

Some older hardware may not have sufficient space on the hard drive to accommodate upgrading directly from one major version to the next. This will become apparent if you first download the base image and then download and install the maintenance release as you will receive an error message saying that the base image is missing. This is caused by the system trying to load the maintenance image by deleting any images that are not in use at the time, which in this case is the base image. For these special cases, follow these steps to upgrade successfully:

  1. Delete any non-essential software images.
  2. Download the base image of the next major version, install, and reboot.
  3. After the reboot, download the maintenance version, install, and reboot.

If you want to, you can also downgrade to a previous version.
