DF - Fuzz Query and Set Security Test (Reliability)
During the Query and Set Security Test, the Fuzz test issues calls to retrieve the security descriptor and change the security state of devices opened by the Basic Open Operations and other open operations, including the operations performed by the Fuzz Sub-opens test.
The Fuzz test issues each query or set call at least 1024 times with a valid buffer and a variety of buffer lengths and security information types (OWNER_SECURITY_INFORMATION, GROUP_SECURITY_INFORMATION, DACL_SECURITY_INFORMATION, SACL_SECURITY_INFORMATION, and no information type). One request of each type is also sent with an invalid buffer pointer and a zero buffer length.
If you use the ChangeBufferProtectionFlags parameter, which sets the protection option, the Fuzz test varies the security setting on the buffer in each query and set call.

Parameters
| Parameter name | Parameter description |
|---|---|
| DQ | A WDTF SDEL query that is used to identify the target device(s) - https://go.microsoft.com/fwlink/?LinkId=232678 |
| Wpa2PskAesSsid | Required ONLY if DUT or one of its child devices is a WiFi adapter. Please provide SSID of a WPA2 AES WiFi network that the test can use to test the WiFi adapter. The default is 'kitstestssid'. |
| Wpa2PskPassword | Required ONLY if DUT or one of its child devices is a WiFi adapter. Please provide password of the WPA2 AES WiFi network specified using the Wpa2PskAesSsid parameter. The default is 'password'. |
| ChangeBufferProtectionFlags | True or False. Changes the memory protection flags of buffers passed to the tested device. The memory protection flags alternates between no access, read-only, and read-only with page guard. |
| Impersonate | True or False. Runs the test as a non administrative user. |
| FillZeroPageWithNull | True or False. Maps the zero page and fills it with NULL values. This test identifies drivers that do not verify a pointer reference before dereferencing a pointer. |
| DoPoolCheck | True or False. Monitors the driver's use of the paged and nonpaged system memory pools by using pool tags and lookaside lists. This option also monitors changes in the number of exceptions handled which might indicate errors in exception handling. |
| DoSync | True or False. Also opens device handles in SYNC mode (FILE_SYNCHRONOUS_IO_ALERT). Random read and write operations are skipped. |
| TestCycles | Number of test cycles. |
| DriverVerifierAdditionalDrivers | Additional drivers that should have Driver Verifier enabled |
| DriverVerifierExcludedFlags | Placeholder for Driver Verifier flags that may be manually excluded for the test run |
| WDKDeviceID | Device id of device under test |
| QueryHardwareID | Hardware id of device under test |
| WDTFREMOTESYSTEM | Required ONLY if DUT or one of its child devices is a wired NIC that doesn't have an IPv6 gateway address. If determined to be required, please provide an IPv6 address that the test NIC can ping to test network I/O. Eg: fe80::78b6:810:9c12:46cd |
| DriverVerifierCustomizeConfiguration | Specifies that this test may want to automatically update Driver Verifier settings |
