Securing privileged access

Securing privileged access is a critical first step to establishing security assurances for business assets in a modern organization.

Basic Authentication module for Windows Server IIS 10

In my pursuit of a basic authentication alternative in IIS, other than the built-in Basic Authentication module or Helicon Ape, I came across Devbridge AzurePowerTools.

Reduce Wordfence CPU usage, disable Wordfence “Live Traffic View”

Whenever WordPress is using a lot of CPU and you have Wordfence Security plugin enabled, it is recommended to double check some settings.

Check WordPress Core files integrity
