log4j remediation tasks

Hello Experts,

Can someone please advise on high level general steps to remediate Log4j in a Windows shop? Servers, computers, and so on.

Is there an official plan and/or patches to remediate this? If so, can you please be so kind and share here?

First step is to find out whether the system in question actually has any software installed that uses the Apache logging modules.  If not, call it a day and have a well-deserved beer.
You should apply various principles that can minimize the potential for damage even before a vulnerability such as Log4J is known. These include:
  • implementing multiple layers of defense
  • minimizing permissions to only permitted users
  • maintaining a stance of (SbD) Security by Default
In the case of Log4J, effective security monitoring and intrusion detection, and prevention help detect a breach before the vulnerability is made public.
