Security Rules..

First we will delete the Ingress Rule allowing TCP in our Default Security to check the Results...

Click on the three dot Actions menu available in TCP rule container and click Remove

Now when will try to login in PUTTY its showing an ERROR....

152.56.172.163/32

Now lets allow TCP connection over Port 22 but we will add our self Public IP [What Is My IP Address]

(https://whatismyipaddress.com/)

Now we Have to create a new Ingress Rule and add our specific IP by adding /32 in last of IP Address...

Create Ingress Rule

Now we will lets Check Back by logging in Putty...
