Introduction

Syslog (System Logging Protocol) is a standard protocol used to send system log or event

Which default port do you need to allow on any internal firewalls to allow a host to send messages by syslog to a SIEM management server?
Record of a security or network incident that is based on one or more logs, and on a customizable set of rules that are defined in the Event Policy. messages to a specific server, the syslog server.

The syslog protocol is enabled on most network devices, such as routers and switches.

Syslog is used by many log analysis tools. If you want to use these tools, make sure Check Point logs are sent to from the Security Gateway

Which default port do you need to allow on any internal firewalls to allow a host to send messages by syslog to a SIEM management server?
Dedicated Check Point server that runs Check Point software to inspect traffic and enforce Security Policies for connected network resources. to the syslog server in syslog format.

Check Point supports these syslog protocols: RFC 3164 (old) and RFC 5424 (new).

These features are not supported: IPv6 logs and Software Blade

Which default port do you need to allow on any internal firewalls to allow a host to send messages by syslog to a SIEM management server?
Specific security solution (module): (1) On a Security Gateway, each Software Blade inspects specific characteristics of the traffic (2) On a Management Server, each Software Blade enables different management capabilities. logs.

Configuring Security Gateways

By default, Security Gateway logs are sent to the Security Management Server

Which default port do you need to allow on any internal firewalls to allow a host to send messages by syslog to a SIEM management server?
Dedicated Check Point server that runs Check Point software to manage the objects and policies in a Check Point environment within a single management Domain. Synonym: Single-Domain Security Management Server..

You can configure Security Gateways to send logs directly to syslog servers.

Important - Syslog is not an encrypted protocol. Make sure the Security Gateway and the Log Proxy are located close to each other and that they communicate over a secure network.

Procedure

      1. In the , click > .

      2. Configure these fields:

        • - Enter a unique name.

        • - Enter the correct IPv4 address of the syslog server.

        • - Optional: Enter the correct IPv6 address of the syslog server. This requires the IPv6 Support be enabled on the Security Gateway / each Cluster Member

          Which default port do you need to allow on any internal firewalls to allow a host to send messages by syslog to a SIEM management server?

      3. Click .

    4. Create the object that represents the Syslog server:

      1. In the , click > > > .

      2. Configure these fields:

        • - Enter a unique name.

        • - Select an existing host or click to define a new computer or appliance.

    Which default port do you need to allow on any internal firewalls to allow a host to send messages by syslog to a SIEM management server?
    Two or more Security Gateways that work together in a redundant configuration - High Availability, or Load Sharing. object.

    Which default port do you need to allow on any internal firewalls to allow a host to send messages by syslog to a SIEM management server?
    Instructions

    1. Double-click the Security Gateway object.

    2. From the left tree, click .

    3. In the table, click the green () button to select the object(s) you configured earlier.

      Notes:

      • You can configure a Security Gateway / Cluster Member to send logs to multiple syslog servers.

        All syslog servers selected in the Security Gateway / Cluster object must use the same protocol version: BSD Protocol or Syslog Protocol.

      • You cannot configure a Syslog server as a backup server.

    4. Click .

    5. Install policy.

  3. Configure the logging properties of the Security Gateways / each Cluster Member.

    Note - In Cluster, you must configure each Cluster Member in the same way.

    The kernel parameter enables or disables the feature on Security Gateways:

    • Value = Disabled (default)

    • Value = Enabled

    You can enable or disable the feature temporarily (until the Security Gateway reboots), or permanently (survives reboot).

    Which default port do you need to allow on any internal firewalls to allow a host to send messages by syslog to a SIEM management server?
    To see the current state of the Syslog in Kernel feature

    1. Connect to the command line on the Security Gateway / each Cluster Member.

    2. Log in to the Expert mode.

    3. Run:

      fw ctl get int fwsyslog_enable

      Output:

      • "fwsyslog_enable = 0" means the feature is disabled (default)

      • "fwsyslog_enable = 1" means the feature is enabled

    Which default port do you need to allow on any internal firewalls to allow a host to send messages by syslog to a SIEM management server?
    To enable the Syslog in Kernel feature permanently (survives reboot)

  2. In each command line connection, log in to the Expert mode.

  3. In the first shell, run:

    fw ctl zdebug | grep logs

  4. In the second shell, run:

    fw ctl set int fwsyslog_print_counter 1

  5. In the first shell, see the counter for each CoreXL Firewall instance and the sum of all CoreXL Firewall instances.

    Sample output:

    ;[cpu_2];[fw4_0];Number of logs sent from instance 0 is 43;

    ;[cpu_2];[fw4_0];Number of logs sent from instance 1 is 39;

    ;[cpu_2];[fw4_0];Number of logs sent from instance 2 is 50;

    ;[cpu_2];[fw4_0];Total logs sent from kernel (all instances) = 132;

  6. In the first shell, press CTRL+C to stop the debug.

Which two factors do you need to account for when collecting an event timeline using a SIEM?

Which two factors do you need to account for when correlating an event timeline using an SIEM? you need to validate that all log sources were synchronized to the same time source. you need to account for any variations in time zone for the different sources.

What options are there for ingesting data from a unified threat management UTM appliance deployed on the network edge to an SIEM?

What options are there for ingesting data from a unified threat management (UTM) appliance deployed on the network edge to an SIEM? If supported, you could deploy agent software to the UTM. If an agent is not supported, you can push data to the SIEM using a protocol such as syslog.

What distinguishes an unknown threat from a known threat?

A known threat can be identified by automated detection tools, such as an anti-virus scanner, intrusion detection system (IDS), or vulnerability scanner. Unknown threats are those that cannot be identified from a static signature.
