Configuring QoS on Palo Alto Firewalls: Class-based Policies, QoS Profiles, Enabling QoS on Firewall Interfaces

Palo Alto Firewalls - Understanding and configuring QoSThis article’s purpose is to help you quickly master Palo Alto QoS concepts and learn to configure QoS on Palo Alto Firewalls in a simple and efficient way. QoS is considered a complicated topic however thanks to Palo Alto’s intuitive firewall GUI interface and our real-scenarios, you’ll quickly grasp all necessary QoS basics and be ready to implement your own QoS policies!

You’ll learn basic QoS terms such as Ingress and Egress traffic, Differentiated Service Code Point (DSCP), Traffic Policing, Traffic Shaping, Palo Alto QoS Classes, Palo Alto QoS Policies, how to build Palo Alto QoS policies, how to configure Palo Alto QoS Classes and finally how to enable and monitor QoS on Palo Alto firewall interfaces (both standalone & AE Aggregate interfaces), view QoS bandwidth graphs and more!

Introduction to Palo Alto QoS

QoS was born from the IEEE group during 1995-1998 by establishing the standard IEEE 802.1P. The main purpose of QoS is to prioritise desired traffic over other type of traffic or to limit the amount of bandwidth applications can consume, by utilizing different mechanisms. This ensures network performance, avoids bottlenecks, congestion or overutilization of network links. A frequently used example of QoS is the prioritising Real-time traffic e.g voice or video, over other type of traffic:

In the example above, voice packets (blue) are given a higher priority against others, therefore immediately being forwarded by the firewall out via the output interface. Since voice packets are very sensitive to delay, they are usually handled with priority to avoid issues in a real-time voice streams e.g VoIP telephone call between two endpoints.

Dealing with Security Audit Challenges: Discovering vulnerabilities, unauthorized access, optimize network security & reporting

manageengine firewall analyzer - dealing with security audit challengesThe utilization of log analyzers, such as Firewall Analyzer, in network infrastructure plays a pivotal role in enhancing cybersecurity and fortifying the overall security posture of an organization. Security audits, facilitated by log analyzers, serve as a critical mechanism for systematically reviewing and analyzing recorded events within the network.

This proactive approach enables the identification of potential security risks, unauthorized access attempts, and abnormal activities that might signify a breach. The log analyzer sifts through vast amounts of data & logs, providing insights into patterns and anomalies that might go unnoticed otherwise.

By uncovering vulnerabilities and irregularities, organizations can take timely corrective actions, preventing potential security breaches. Moreover, the information gleaned from these audits is instrumental in formulating a comprehensive security strategy that extends across the entire network infrastructure.

How to Manually Download, Import & Install PAN-OS on Palo Alto Firewalls via CLI & Web GUI interface

Palo Alto PAN-OS Manual update - upload - upgradeThis article provides comprehensive guidance on the manual processes involved in downloading, uploading, and installing (import) any PAN-OS version on a Palo Alto Firewall. It details the steps for searching and downloading the desired PAN-OS version, as well as the supported methods for uploading the software to your Palo Alto Firewall, including Web, TFTP, and SCP. Additionally, the article offers valuable tips aimed at facilitating a smooth and successful upgrade process.

The necessity for a manual upgrade of a Palo Alto firewall arises in instances where the system operates within an isolated environment employing air-gap architecture and lacks direct internet access. This requirement is further applicable in scenarios where the firewall is devoid of valid licenses, remains unregistered, or serves as a replacement unit as exemplified in a Return Merchandise Authorization (RMA) context.

Whether performing upgrades manually or automatically, it is crucial to consider the same upgrade path rules outlined in our article Complete guide to upgrading Palo Alto firewalls. Individuals unfamiliar with these rules are strongly encouraged to review the article before initiating any PAN-OS upgrade.
