Check Point Firewalls Troubleshooting Expert Course (CCTE)

Describe the Check Point three-tier architecture, with tier one smart console applications, tier two management servers, and tier three gateways, highlighting reduced dependencies and uninterrupted traffic when management is down.

Learn to install and configure a Check Point management server and security gateway on a virtual machine using open server installation, Gaia, and access the smart console for management.

Configure a Check Point security gateway with Gaia OS and a management server to establish secure internal communication, define topology with internal and external interfaces, and install the policy.

Explain the difference between clean up and stealth rules in a checkpoint firewall: clean up drops and logs traffic, while stealth restricts admin access and keeps the gateway transparent.

Explore the new smart console dashboard to manage incidents, view and configure security policy rules in packet mode, and configure anti-spoofing on Check Point firewalls.

Learn to use Check Point firewall CLI tools in Gaia, switch to export mode, set expert passwords, add or delete administrators, and perform backups and restores.

Apply a Check Point SAM rule to block attacker IPs and observe its impact on firewall CPU and memory, with live monitoring and drop logging.

Explore Check Point firewall architecture, detailing management and gateway components, and how FWM, FWD, FWSSD, CPD, and CPWD run in user and kernel modes with SIC and traps.

Explore Opsec debugging infrastructure and open platform security, using debug levels to observe kernel and user mode processes. Learn to isolate specific functionality within a cpd process using debug flags.

Understand stateful inspection in checkpoint firewalls, using an inspection engine and connection tables to track approved traffic, with kernel tables and reverse entries enabling fast rule matching and throughput.

Explore how a Check Point firewall uses the connection table to track inbound and outbound traffic, apply policy rules, and decide allow or deny via stateful inspection and logs.

Diagnose user access issues on a Check Point firewall using advanced kernel debugs, analyze logs, and capture traffic to support root-cause analysis and precise user communication.

Analyze Check Point firewall packet inspection stages from inbound arrival through policy checks to outbound routing, using fw monitor, tcpdump, and Wireshark for troubleshooting and log analysis.

Learn how to configure Wireshark to display Check Point firewall chains with step-by-step Windows procedures, including protocol steps, column customization, and visualizing firewall analysis outputs.

Learn to use fw monitor and tcpdump to observe firewall inspection points and build monitor expressions. Analyze packet flow, flags, and VPN-related RTT insights for troubleshooting.

Learn how Check Point firewall CoreXL enables multi-core load balancing, deep inspection, and high throughput with multiple independent kernel instances handling traffic.

Demonstrate corexl inside view by allocating cpu affinity and dispatchers to specific cpus and interfaces, and adjusting kernel instances through reconfiguration.

Investigate security concepts and secure xl gateway performance optimization. Understand packet acceleration, security API, and how hardware-level validation boosts firewall and VPN throughput.

Discover how SecureXL accelerates Check Point gateway performance by offloading initial connections to secure software, using connection templates and the security API, and enabling VPN routing and wired traffic handling.

Learn how SecureXL and the Secure Network Dispatcher integrate inside a firewall, routing packets through a multi-stage processing path from dispatcher to IP-level checks.

Explore CoreXL and security in detail with real-time examples, focusing on external dispatcher, secure X, assembly interactions, and firewall processing to understand performance and packet flow.

Explore how the Check Point security management server stores databases of objects, users, policies, and policy packages, and how backups and active and standby synchronization support high availability.

Explore ClusterXL acceleration and clustering as Check Point high-availability and load-sharing solutions, including state synchronization, ccp, unicast and multicast load shedding, and sticky connections for enterprise networks.

Understand VRRP, a virtual routing redundancy protocol that enables firewall clusters to provide high availability and load shedding, with monitors to manage master and backup failover.

Learn checkpoint vpn troubleshooting basics by detailing ipsec vpn with ike, phase one and phase two exchanges, encryption domains, peers, and authentication, using ike view for packet flow analysis.

Learn how Check Point VPN tunnel management boosts gateway interoperability, controls VPN tunnel creation and permanence, and uses testing packets and alerts to ensure continuous connectivity.

Learn to set up high availability for remote access VPNs with multiple gateways and meet VPN configurations, using explicit or implicit selection, probing, and load distribution.

Learn to configure a site-to-site vpn between corporate and branch offices using a central and satellite gateway, define vpn domains, create vpn communities, and test and troubleshoot connections.

Master Check Point VPN troubleshooting commands to diagnose encryption negotiations, review logs, and adjust debugging to resolve VPN domain and phase one and phase two mismatches.

Check Point firewall handles static, hide, and manual nat, detailing source and destination translation, private ip addressing, public ip addresses, and policy-driven traffic flow through the security gateway.

Explore how Check Point firewall NAT and security servers enforce policies, inspect the first packet, manage inbound and outbound connections, and leverage automatic NAT bases for secure access.
