Kali Linux***
uses msf framework to make win7 eternal blue***【defense】
Ways to defend ms17_101:
1. Install anti-virus software
2. Close port 445
3. Open the computer's firewall function
Defense methods:
1. Turn off file sharing
1.1 First, we will proceed to the Eternal Blue chapter to test whether the target computer can be connected.
You can see that we have successfully connected. 
2.1 Then we open the Control Panel -> Network and Internet -> Network and Sharing Center -> Advanced Sharing Settings. Turn off network discovery and file sharing, and click Save and modify. 
2.2 We open kali again and use the eternal blue loophole to make a *** attempt. 
2.3 When we shut down the sharing service, VPN will not be able to use the Eternal Blue loophole to attack our computer again.
2. Turn on the firewall
2.1 First , turn on all network sharing to test whether Kali can be successful on the target machine. 
2.1 You can see that the *** has been successful now, now open cmd and enter the command firewall.cpl to open the firewall control center. 
2.2 Set all windows firewalls to on, and click OK.
2.3 Let's use kali again to conduct a *** test to see if it can be successful. 
2.4 It can be seen that when our firewall is turned on, it can also resist ***.
3. Modify firewall inbound rules and install anti-virus software
3.1 Now we modify the firewall inbound rules in advanced settings. 
3.2.1 Select the stacking rule -> New rule -> Port -> 
3.2.2 Select TCP, the specific local port 445, and then the next step. 
3.2.3 Choose to block the connection. 
3.2.4 Go to the next step without modification. 
3.2.5 The name and description can be set by yourself. 
3.3 After the establishment of the rules is complete, we will use kali again to conduct a *** test to see if the *** is successful. 
3.4 In addition to these three ways to resist the vulnerabilities of Eternal Blue, we can also install anti-virus software, which can help us resist the harm of the virus through the security detection of the anti-virus software.
