The original "Security Update 2019-004 (High Sierra & Sierra)" contained a bug that affected Sleep mode on a few recent Mac models. Without explanation, Apple pulled the update for several days. Then, without explanation, Apple made the update available again with modifications that removed the Sleep bug.
If you have questions about whether you have the correct version installed, simply download and install this latest version. For details, please read:

I download and applied this DMG a couple of days ago from the URL mentioned here. The checksum matches the one shown here. Machine rebooted itself as is typical for this kind of update. Today, however, App Store indicates the update needs to be applied, despite the fact that the update shows under Updates Installed In The Last 30 days. However, for that entry, there's a lot of missing information:
Security Update 2019-002
Version
Installed March 27, 2019
The version field is empty, as is the detailed description that's typically shown in the column to the right. I've don't recall seeing an update entry with that information missing before.
Anyone else have this experience?
My guess, based upon the fact that Apple had a December date on the download page, and the fact that this update was not immediately available through the App Store for High Sierra until today is that the download mentioned here may not have been the same as the actual release version that's showing up today.
It appears that App Store has already finished downloading the update, and is ready to apply and restart. I would love to find that download to compare the checksums. I've already looked in $TMPDIR../C/com.apple.appstore/, and it's not there.
Does anyone know where the download might be?
The SHA-256 hash for the current file is 27765011d7028a643516e5ac106033b6340ee00f261f8e85ae444653d5a17211
For those of us who installed the earlier file, the missing meta data is probably the reason this happened - considering the file size is minimally different. That explains everything including the update re-appearing in the App Store Updates.

And Mojave doesn’t get a security update, instead they get 10.14.3
