Security Servers

Overview

Security Servers on a Security Gateway Dedicated Check Point server that runs Check Point software to inspect traffic and enforce Security Policies for connected network resources. are user space processes that perform content security and authentication for various protocols.

The parent process FWD on a Security Gateway starts the applicable Security Server process in these cases:

In an Access Control rule Set of traffic parameters and other conditions in a Rule Base (Security Policy) that cause specified actions to be taken for a communication session., the Services & Applications column contains a Resource object.
In an Access Control rule, the Action column contains the value User Auth or Client Auth.
An IPS Check Point Software Blade on a Security Gateway that inspects and analyzes packets and data for numerous types of risks (Intrusion Prevention System). protection requires a Security Server process to complete its inspection.

The Security Server processes save their messages in the corresponding log files (see sk97638).

The $FWDIR/conf/fwauthd.conf file on a Security Gateway contains the list of the supported Security Server user space processes:

Important Notes

Do not make any changes in the $FWDIR/conf/fwauthd.conf file, unless Check Point R&D or Support explicitly told you to do so.
In a Cluster Two or more Security Gateways that work together in a redundant configuration - High Availability, or Load Sharing., you must configure all the Cluster Members in the same way.

Before you make any changes in the $FWDIR/conf/fwauthd.conf file, create a backup copy:

On a Security Gateway / each Cluster Member Security Gateway that is part of a cluster.:

cp -v $FWDIR/conf/fwauthd.conf{,_BKP}

On a Scalable Platform Security Group A logical group of Security Appliances (in Maestro) / Security Gateway Modules (on Scalable Chassis) that provides Active/Active cluster functionality. A Security Group can contain one or more Security Appliances / Security Gateway Modules. Security Groups work separately and independently from each other. To the production networks, a Security Group appears a single Security Gateway. In Maestro, each Security Group contains: (A) Applicable Uplink ports, to which your production networks are connected; (B) Security Appliances (the Quantum Maestro Orchestrator determines the applicable Downlink ports automatically); (C) Applicable management port, to which the Check Point Management Server is connected.:

g_all cp -v $FWDIR/conf/fwauthd.conf{,_BKP}

If you changed the $FWDIR/conf/fwauthd.conf file on a Scalable Platform Security Group, then you must copy the modified file to all Security Group Members Member of a Security Group in ElasticXL Cluster, Maestro, and Scalable Chassis. Acronym: SGM.:

asg_cp2blades $FWDIR/conf/fwauthd.conf}

After you make changes in the $FWDIR/conf/fwauthd.conf file, it is necessary to stop and start all Check Point process with the "cpstop ; cpstart" commands.

This stops all traffic through the Security Gateway / Cluster / Security Group.

In a cluster, this can cause a failover.

respawn

Makes sure that one Security Server process is always running.

wait

respawn

Controls how many Security Server process to start:

Value "0" means that only one Security Server process starts.
Value "8" means that a maximum of eight Security Server processes start.
Minus in front of the number means that the same Security Server process inspects the same connection (sticky inspection).
Values "259" and "900" are reserved for Client Authentication and denote a port number.

0

-8
