To resolve the issue of the window of vulnerability (WoV), we would need to get the patch from Microsoft. According to Microsoft, it will take up to 3 days for the patch to be available. Then, we would need additional time to download and test the patch to make sure that this is what is needed to fix the security breach on the SMB server. After doing the testing, the IT department would need time to install the patch onto the servers and deploy to the client computers.
This will take 2 days to do, depending on the IT staff, if they work on weekends will determine the completion date. Meaning, if they will work on the weekend, then the deployment to all computers and servers will be done by that Sunday. If not, then it will be the following Tuesday. So, the time that is needed would be a week. To recap, the security breach was reported on a Friday. On Monday, looked on Microsoft’s website to see when the patch would be released, and it indicated that it would take 3 days for it to be available.
Counting Monday, 3 days would be, Wednesday. Depending on the time that the patch is released on Wednesday, would need an additional 2 days to download and test the patch before deploying, if early Wednesday, then Thursday to test. But if it comes late Wednesday, then it would take Thursday and Friday to test. Then that would leave the weekend, if the IT staff would work on the weekend. But if not, then it is going to restart on Monday and complete on Tuesday.
