Checkpoint Firewall Policy installation flow process

Checkpoint Firewall Policy installation flow process

Policy installation flow process
Solution
Policy installation flow:
  1. Assuming the initiation was made by the SmartDashboard, as opposed to using command line options, such as fwm load (on Management Server) or fw fetch (on Security Gateway), the Check Point Management Interface (CPMI) policy installation command is sent to FWM process on the Management Server where the verification and compilation takes place.
  2. FWM process is responsible for code generation and compilation.
  3. FWM process invokes the Check Point Policy Transfer Agent (CPTA) command that sends the policy to all applicable Security Gateways.
  4. CPD process on the Security Gateway receives the policy and verifies its integrity.
  5. FWD process on the Security Gateway updates all of the user-mode processes responsible for enforcement aspects. These include VPND process for VPN issues, FWSSD processes for Security Server issues, and so on. Once complete, the CPD process then initiates the update for Check Point kernel.
  6. The new policy is prepared, and the Check Point kernel holds the current traffic and starts queuing all incoming traffic.
  7. The Atomic Load takes place. This process should take a fraction of a second.
    Note: During Atomic Load, SecureXL is disabled and re-enabled afterwards.
  8. The traffic queue is released, and all of the packets are handled by the new security policy.

How to modify SSH/HTTP/Telnet time out in Cisco ASA firewall?

How to modify SSH/HTTP/Telnet time out in Cisco ASA firewall? By default tcp idle timeout is 1:0:0 hh:mm:ss. If in case you need to modify it you can do it by MPF (Modular Policy Framework). Let us setup a custom timeout when traffic is coming from particular host 10.77.241.129. !— Match the traffic using the access-list —! object-group service DM_INLINE_TCP_1 tcp port-object eq www port-object eq ssh port-object eq telnet access-list outside_mpc extended permit tcp host 10.77.241.129 <source ip> any object-group DM_INLINE_TCP_1 !— Define the class map Cisco-class –! class-map Cisco-class match access-list outside_mpc !— Call this class-map into policy map and set the connection reset after 10 min when traffic is coming from particular host —! policy-map Cisco-policy class Cisco-class set connection timeout idle 0:10:00 reset !— Apply the policy-map Cisco-policy on the interface. —! service-policy Cisco-p...

CLI Commands for Troubleshooting FortiGate Firewalls

CLI Commands for Troubleshooting FortiGate Firewalls 2015-12-21 Fortinet , Memorandum , Network Cheat Sheet , CLI , FortiGate , Fortinet , Quick Reference , SCP , Troubleshooting Johannes Weber This blog post is a list of common troubleshooting commands I am using on the FortiGate CLI . It is not complete nor very detailled, but provides the basic commands for troubleshooting network related issues that are not resolvable via the GUI. I am not focused on too many memory, process, kernel, etc. details. These must only be used if there are really specific problems. I am more focused on the general troubleshooting stuff. I am using it personally as a cheat sheet / quick reference and will update it from time to time. Coming from Cisco, everything is “show”. With Fortinet you have the choice confusion between show | get | diagnose | execute . Not that easy to remember. It is “ get router info6 routing-table” to show the routing table but “ diagn...
