Checkpoint 156-582 - Check Point Certified Troubleshooting Administrator - R81.20 (CCTA)

TheFWDprocess communicates between the Security Management Server and the Security Gateway to forward logs usingTCP port 257. This port is designated for log transmission, ensuring that logs are efficiently and securely sent from the gateway to the management server for centralized analysis and storage.

To check the connection status between a gateway and the Log server, use the netstat -anp | grep :257 command inexpert modeon the Log server. This command filters the network connections to display only those related to port257, which is used for log collection. Running it in expert mode provides the necessary privileges to view detailed network information.

The cpstat command is a versatile tool provided by Check Point to display status and statistics for various Check Point products and applications. It offers insights into system performance, service statuses, and resource utilization, which are essential for diagnosing and resolving issues effectively.

SmartConsolecommunicates with the Security Management Server using theCPM(Check Point Management) process overport 19009. This communication is essential for managing policies, retrieving logs, and performing administrative tasks within the Check Point environment.

The top command in Linux provides a real-time, dynamic view of system processes, showing CPU and memory usage among other metrics. It is the most suitable command for monitoring process resource utilization continuously. In contrast, df displays disk space usage, free shows memory usage, and ps provides a snapshot of current processes but without the dynamic, real-time monitoring that top offers.

The"Super User"permission profile in SmartConsole includes all the capabilities of the"Read Write All"profile and additionally grants the ability to make changes within the Gaia operating system. This elevated permission level allows for more comprehensive administrative control, including system-level configurations that are not available to "Read Write All" users.

Port257is used for log collection and communication between the Security Management Serverand the Security Gateway. Verifying that this port is open and accessible ensures that logs are successfully transmitted from the gateway to the management server, facilitating effective monitoring and analysis.

The commandfw monitor -p allinitiates packet capturing acrossall 15 inbound and outbound moduleswithin the Check Point inspection chain. This comprehensive capture allows for thorough analysis of packet flow and behavior at every stage of processing, facilitating detailed troubleshooting and performance evaluation.

To log a full list of URLs when a specific rule is triggered in the Rule Base, you shouldset Extended logging under the rule's log type. This configuration ensures that detailed information, including the URLs accessed, is captured in the logs whenever the rule is matched. This level of logging provides comprehensive visibility into user activities and helps in detailed auditing and analysis.

When tcpdump causes high CPU usage, an alternative is to use cppcap, which is optimized for capturing packets with lower CPU overhead in Check Point environments. cppcap is designed to work efficiently with Check Point's infrastructure, reducing the performance impact compared to generic tools like tcpdump.
