ObjectSecurity.SetSecurityDescriptorBinaryForm Method (Byte[], AccessControlSections)

 

Sets the specified sections of the security descriptor for this ObjectSecurity object from the specified array of byte values.

Namespace:   System.Security.AccessControl
Assembly:  mscorlib (in mscorlib.dll)

public void SetSecurityDescriptorBinaryForm(
	byte[] binaryForm,
	AccessControlSections includeSections
)

Parameters

binaryForm
Type: System.Byte[]

The array of bytes from which to set the security descriptor.

includeSections
Type: System.Security.AccessControl.AccessControlSections

The sections (access rules, audit rules, owner, primary group) of the security descriptor to set.

If the security descriptor represented by the binary data contains null for its discretionary access control list (DACL), a single access control entry (ACE) that allows everyone full access (AEFA) is added to the DACL. If an application modifies the DACL of a security descriptor to which an AEFA ACE has been added, the AEFA ACE is persisted with the DACL when that DACL is persisted.

This can result in an application unintentionally allowing access to principals. Because of this, an application should check for the existence of an AEFA ACE and remove it before modifying any security descriptor.
