2. Create a new security group based on your current ip address and change the security group name of CND.py to your security group name:

    SecurityGroups= ['YourSecurityGroups']
   

3. Create a S3 bucket to store log files

4. Install Boto3 and Fabric

   pip install Boto3
   pip install Fabric

6. Run the following command:

   fab -f CND.py start:T=200,D=2,N=8
