Cannot disable read access the Windows 7 security log

So we have some Windows 7 systems with some security requirements. I am trying to disable read access the security log. The command “wevtutil gl security” shows a result of the following:

channelAccess: O:BAG:SYD:(A;;0xf0007;;;SY)(A;;0x7;;;BA)(A;;0x7;;;SO)(A;;0x3;;;IU)(A;;0x7;;;SU)(A;;0x3;;;S-1-5-3)(A;;0x1;;;S-1-5-32-573)

Open in new window


From what little I know of these things, I am thinking that the “(A;;0x3;;;IU)” is giving interactive users read and write of the log (they cannot clear it)

What puzzles me is that the command

wevtutil sl security /ca:O:BAG:SYD:(A;;0xf0007;;;SY)(A;;0x7;;;BA)(A;;0x7;;;SO)(A;;0x7;;;SU)(A;;0x3;;;S-1-5-3)(A;;0x1;;;S-1-5-32-573)

Open in new window


shows immediate results on our normal windows 7 PC’s, but it does NOTHING on the machines in question. The command runs, gives no error, but “wevtutil gl security” still shows the “(A;;0x3;;;IU)” in the channelAccess string.

What am I doing wrong?
