I had serous issues with SecUpdates from the App Store update page over a year ago and since, when I get a notice a SecUpdate is available, I now go to the Apple Downloads site:


Apple - Support - Downloads


Not a hint of trouble since on out three most-used Macs in the home office.


Note: After installing from the download page, the App Store updates pager(10.13 and earlier ) or System Prefs >Software updates, may continue to show the update available for a couple of days but it will go away with no action required on your part.
