Currently my policy is configured with the number of hosts in parallel is 20 with 5 checks. I am running 3 clients simultaneously so I am thinking of changing the policy to the number of hosts in parallel is 6 with 10 checks. Also I will monitor the CPU and memory utilization.
I am scanning around 800 windows servers Pentium 3 Safe checks= on Log details of the scan on the server=on Nessus TCP scanner=on Ping the remote host= on Thanks for your feedback!
