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.

Packet flows and acceleration

Given today's threat landscape and an ever-increasing emphasis on security, you would think that every packet traversing, entering, or leaving our network must be inspected with prejudice before being allowed to pass. This, clearly, is not the case, as doing that would simply use up unnecessary CPU cycles and negatively impact performance, while not improving security in the least.

Check Point utilizes the following proprietary technologies to achieve the best possible traffic processing speed for its firewalls:

  • CoreXL is the load balancing mechanism that assigns CPU cores for either acceleration and packet routing duties, Secure Network Distributor (SND), or for deep packet inspection, FireWall Worker (fwk).
  • SecureXL is the traffic routing and acceleration mechanism that increases throughput and connection rate using either software or dedicated acceleration cards (SecureXL instances) and chooses the fwk processes that will handle...
