Palo Alto Study Notes: Firewall Configuration Essentials I (101)

To view Firewall Configuration Essentials 101 Course, please login to the Palo Alto Networks Learning Center.





1. Palo Alto Networks Platforms


The PA-500, PA-200, and VM-Series firewalls do not support virtual systems. High Availability and Aggregated interfaces are also only supported on higher models of the product.


The even-numbered platforms are older platforms. The PA-4000 is End-of-Sale. The PA-3000 and PA-5000 models use superior hardware, such as Cavium chips and SSD for logging. The PA-7050 is a chassis architecture.





The Control Plane has its own dual core processor, RAM, and hard drive. This processor is responsible for tasks such as management Ul, logging, and route updates.

The Data Plane contains three types of processors that are connected by high speed 1Gbps busses:

  • Signature Match Processor: Performs vulnerability and virus detection
  • Security Processors: Multi-core processors, which handle security tasks such as SSL decryption
  • Network Processor: Responsible for routing, NAT, and network layer communication


2. Initial Access to the System


2.1 Initial Access to the System
  • Connect a serial cable from your computer to the Console port and connect to the firewall using terminal emulation software (9600-8-N-1). Wait a few minutes for the boot-up sequence to complete; when the device is ready, the prompt changes to the name of the firewall, for example PA-500 login .
  • Connect an RJ-45 Ethernet cable from your computer to the MGT port on the firewall. From a browser, go to https://192.168.1.1 . Note that you may need to change the IP address on your computer to an address in the 192.168.1.0 network, such as 192.168.1.2, in order to access this URL.





2.2 Configuration Management


  • Candidate Config: When you change a configuration setting and click OK, the current or "candidate" configuration is updated; not the active or "running" configuration.

Why CIS Benchmark for Palo Alto Firewall

1. Introduction: Why the C.I.S Benchmark for Palo Alto Firewall is Crucial

In today's digital age, network security is of utmost importance. Cyberattacks are becoming more sophisticated and frequent, and businesses must take proactive measures to protect their networks. One such measure is implementing the C.I.S Benchmark for Palo Alto Firewall. This benchmark provides a set of guidelines and best practices for configuring and securing your firewall. In this article, we will discuss why the C.I.S Benchmark for Palo Alto Firewall is crucial and how it can help you protect your network from potential threats.

2. Understanding the C.I.S Benchmark for Palo Alto Firewall

The C.I.S Benchmark for Palo Alto Firewall is a set of guidelines that provide organizations with a comprehensive checklist to secure their network. It is a globally recognized standard that outlines the best practices for configuring and managing Palo Alto Firewalls. The benchmark covers a wide range of security controls, including network configuration, access control, logging and monitoring, and much more.

The C.I.S Benchmark for Palo Alto Firewall is regularly updated to keep up with the latest threats and vulnerabilities. The benchmark is developed by a team of security experts who analyze the latest attack vectors and develop countermeasures to mitigate them. By implementing the C.I.S Benchmark for Palo Alto Firewall, organizations can ensure that their network is protected against the latest threats.

The C.I.S Benchmark for Palo Alto Firewall is designed to be flexible and adaptable to different environments. It provides organizations with a baseline configuration that can be customized to meet their specific needs. This means that organizations can tailor their security controls to their unique requirements while still adhering to the industry-standard best practices.

Overall, understanding the C.I.S Benchmark for Palo Alto Firewall is crucial for any organization that wants to secure its network. By following the guidelines outlined in the benchmark, organizations can ensure that their Palo Alto Firewalls are configured correctly and that they have the necessary security controls in place to protect against the latest threats.

3. Benefits of Implementing the C.I.S Benchmark for Palo Alto Firewall

Implementing the C.I.S Benchmark for Palo Alto Firewall offers numerous benefits to organizations.
