Applies to: desktop apps only

The LandAttackDetectionEnabled property gets or sets a Boolean value that indicates whether Forefront TMG will generate an event when a land attack is detected.

A land attack is one in which a Transmission Control Protocol (TCP) SYN packet is sent with a spoofed source IP address that matches the destination IP address of the Forefront TMG computer and with a port number that is allowed by the Forefront TMG rules so that the Forefront TMG computer will try to establish a TCP session with itself. If the attack succeeds, the computer enters a closed loop and must be restarted.

This property is read/write.

Syntax

HRESULT put_LandAttackDetectionEnabled(
  VARIANT_BOOL fLandAttackDetectionEnabled
);

HRESULT get_LandAttackDetectionEnabled(
  VARIANT_BOOL *pfLandAttackDetectionEnabled
);

Property value

Boolean value that indicates whether Forefront TMG will generate an event when a land attack is detected.

Error codes

These property methods return S_OK if the call is successful; otherwise, they return an error code.

Remarks

This property is read/write. Its value is set to True (VARIANT_TRUE in C++) during Forefront TMG setup.

Land attacks can be detected only if the IntrusionDetectionEnabled property is set to True (VARIANT_TRUE in C++).
