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.

Creating rules for the firewall/networking layer

Since a Gateway Access rule is already present, the next rules are listed as follows:

  • DHCP
  • Dynamic Routing
  • Noise Suppression

These three are interconnected in that all of them are related to traffic addressed to the gateways. Because of this, these three sections are located higher up in the policy than the Stealth Rule section.

The Noise Suppression section and rules are there to drop and avoid logging useless traffic, specifically, the broadcast traffic from connected networks and the general broadcast. However, DHCP relies on it, so the relevant section must be positioned higher. Additionally, we are supposed to define objects representing the broadcast addresses for connected networks and general broadcasts.

Defining hosts for broadcast addresses

To handle broadcast traffic, we have to create a number of dummy host objects with broadcast addresses. In SmartConsole, launch the COMMAND LINE window from...
