About the defense of the blackmail virus

The 445th and 139th vulnerabilities of Windows have existed for a long time, and it is only a matter of time before large-scale outbreaks occur. In fact, there are a lot of defense methods, which have long been all over the floor. But it is not easy to deploy defenses quickly, massively and constantly. For example, use port exclusion, delete file and print sharing services, modify the registry, use firewalls, and group policies, or install some antivirus software. I personally think that using group policy is a relatively fast method, there is no need to restart, there is no need to stop the service, and it can be deployed quickly in a large area, especially in a domain environment.

How to use it:

Ensure that the IPSEC service is started

Import security policy
