Free Access Checkpoint 156-315.81 New Release

To determine the cause of a cluster gateway showing "Down" despite running "clusterXL_admin up" on the down member, you can run the following command:

This command will provide a list of cluster members along with their statuses and can help diagnose the issue with the down member.

SecureXL is a technology that improves the performance of Security Gateway by offloading the processing of some packets from the Firewall kernel to the SecureXL device driver1. SecureXL can handle packets in three different paths, depending on the type and state of the packet2:

• Firewall Path: This is the slowest path, where packets are processed by the Firewall kernel and all the inspection blades. This path is used for packets that require full inspection, such as the first packet of a connection, packets that match a rule with a UTM blade, or packets that are not eligible for acceleration.
• Accelerated Path: This is the fastest path, where packets are processed by the SecureXL device driver and bypass the Firewall kernel. This path is used for packets that belong to an established connection that is marked for acceleration, and do not require any further inspection by the Firewall or other blades.
• Medium Path: This is a hybrid path, where packets are processed by both the SecureXL device driver and the Firewall kernel, but skip some inspection steps. This path is used for packets that belong to an established connection that is not marked for acceleration, but do not require full inspection by all the blades.

The other options are not correct because:

• A. Initial Path; Medium Path; Accelerated Path: There is no such thing as Initial Path in SecureXL terminology. The initial packet of a connection is always handled by the Firewall Path.
• B. Layer Path; Blade Path; Rule Path: These are not paths of traffic flow, but components of the unified policy in R80 and above versions. The Layer Path refers to the order of layers in the policy, the Blade Path refers to the order of blades within a layer, and the Rule Path refers to the order of rules within a blade3.
• C. Firewall Path; Accept Path; Drop Path: These are not paths of traffic flow, but possible actions that the Firewall can take on a packet. The Firewall Path is one of the paths of traffic flow, but the Accept Path and Drop Path are not. The Accept Path means that the packet is allowed to pass through the Firewall, and the Drop Path means that the packet is blocked by the Firewall4.

The Correlation Unit in Check Point Security Management performs several actions, but it does not assign a severity level to the event. The Correlation Unit is responsible for identifying patterns in logs, marking logs that are part of larger patterns, generating events based on the Event policy, and adding new log entries to ongoing events. However, assigning a severity level to an event is typically done through the Event policy configuration, not by the Correlation Unit.

The benefit of fw monitor over tcpdump is that with fw monitor, you can see the inspection points, which cannot be seen in tcpdump. Inspection points are the locations in the firewall kernel where packets are inspected by the security policy and other software blades. Fw monitor allows you to capture packets at different inspection points and see how they are processed by the firewall. Tcpdump, on the other hand, is a generic packet capture tool that only shows the packets as they enter or leave the network interface.
