Windows security expert Kevin Beaver offered this response:
Here are five commonly overlooked issues I see all the time after someone has set up a Windows network:
Didn't enable Windows Automatic Updates:
If Windows Automatic Updates is not enabled, then you could be running a network that is susceptible to vulnerabilities that have already been fixed by Microsoft. Learn how to optimize Windows Server Update Services (WSUS) in this tip from Brien M. Posey.
Didn't harden the system based on Microsoft's recommendations and others such as those at the Center for Internet Security website:
You can go over a series of Windows hardening tips in our expert advice section with Windows security expert Jonathan Hassell.
Didn't set up a password policy:
In our Password Security Vault, learn about password policies, password management best practices, how to crack passwords and recover lost passwords as well as harden existing passwords and more.
Did set up a ridiculously stringent password policy that's unreasonably difficult for users to work with:
Didn't set up NTFS file permissions properly, which allows anyone to access anything and create shares at will:
If you don't properly set up NTFS file permissions, you can kiss effective network security management goodbye. You need to set up these permissions for security and network authentication purposes in order to know who can and cannot access your network and what users can do once they are inside.
