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.

Variable objects

Earlier in this chapter, I mentioned variable objects, and now is the time to expand on them a bit. Unlike static objects, which either have static IP addresses or use DHCP but are represented by static objects, such as networks or ranges in the policies, variable objects' addresses can be changed dynamically and are not confined by predefined networks or ranges. As was mentioned earlier, these could be thought of as groups with conditional membership defined outside of the Check Point objects database.

I would have used the term dynamic objects to describe this category, but that term is already reserved by one of the object types under the broader variable objects definition.

So, let's start with dynamic objects since this term has just come up.

Dynamic objects

When a new dynamic object [1] is created in New | Network Object | Dynamic Objects | Dynamic Object, the object itself is empty – it does not have anything in its properties except...
