CoreXL Firewall Instance
On a Security Gateway with CoreXL enabled, the Firewall kernel is copied multiple
times. Each replicated copy, or firewall instance, runs on one processing CPU core.
These firewall instances handle traffic at the same time, and each firewall instance is a
complete and independent firewall inspection kernel. Synonym: CoreXL FW Instance.
CoreXL SND
Secure Network Distributer. Part of CoreXL that is responsible for: Processing incoming
traffic from the network interfaces; Securely accelerating authorized packets (if
SecureXL is enabled); Distributing non-accelerated packets between Firewall kernel
instances (SND maintains global dispatching table, which maps connections that were
assigned to CoreXL Firewall instances). Traffic distribution between CoreXL Firewall
instances is statically based on Source IP addresses, Destination IP addresses, and the
IP 'Protocol' type. The CoreXL SND does not really "touch" packets. The decision to stick
to a particular FWK daemon is done at the first packet of connection on a very high level,
before anything else. Depending on the SecureXL settings, and in most of the cases, the
SecureXL can be offloading decryption calculations. However, in some other cases,
such as with Route-Based VPN, it is done by FWK daemon.
CPUSE
Check Point Upgrade Service Engine for Gaia Operating System. With CPUSE, you can
automatically update Check Point products for the Gaia OS, and the Gaia OS itself. For
details, see sk92449.
D
DAIP Gateway
Dynamically Assigned IP (DAIP) Security Gateway is a Security Gateway, on which the
IP address of the external interface is assigned dynamically by the ISP.
Data Loss Prevention
Check Point Software Blade on a Security Gateway that detects and prevents the
unauthorized transmission of confidential information outside the organization. Acronym:
DLP.
Data Type
Classification of data in a Check Point Security Policy for the Content Awareness
Software Blade.
