ObjectSecurity.SetSecurityDescriptorBinaryForm Method

 

Sets the security descriptor for this ObjectSecurity object from the specified binary data.

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

NameDescription
System_CAPS_pubmethodSetSecurityDescriptorBinaryForm(Byte[])

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

System_CAPS_pubmethodSetSecurityDescriptorBinaryForm(Byte[], AccessControlSections)

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

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.
