Check Point Firewall Administration R81.10+

By: Vladimir Yakovlev

Overview of this book

Check Point firewalls are the premiere firewalls, access control, and threat prevention appliances for physical and virtual infrastructures. With Check Point’s superior security, administrators can help maintain confidentiality, integrity, and the availability of their resources protected by firewalls and threat prevention devices. This hands-on guide covers everything you need to be fluent in using Check Point firewalls for your operations. This book familiarizes you with Check Point firewalls and their most common implementation scenarios, showing you how to deploy them from scratch. You will begin by following the deployment and configuration of Check Point products and advance to their administration for an organization. Once you’ve learned how to plan, prepare, and implement Check Point infrastructure components and grasped the fundamental principles of their operation, you’ll be guided through the creation and modification of access control policies of increasing complexity, as well as the inclusion of additional features. To run your routine operations infallibly, you’ll also learn how to monitor security logs and dashboards. Generating reports detailing current or historical traffic patterns and security incidents is also covered. By the end of this book, you'll have gained the knowledge necessary to implement and comfortably operate Check Point firewalls.

ClusterXL HA failover simulations

While knowing the theory is all well and good, there is nothing better for gaining confidence in the reliability of fault-tolerant solutions than practice. Let’s conduct a few tests in our lab that will illustrate the functionality of ClusterXL in HA mode using two exercises, one for orderly failover and another one for real-life simulation.

Manual failover test

Let’s introduce slight modifications to the security policy:

  1. In the SmartConsole application, navigate to the SECURITY POLICIES | LeftSide_RA policy and disable the rule named SSH access to Router Accept:

  1. Scroll down to the APCL & URLF, Content Awareness Inline Layer policy section and expand its parent rule.
  2. Add two new rules above the existing rule for HTTP and HTTPS [1] (an APCL/URLF Layer cleanup rule [2] is shown for reference):
