The Perfect Scan

Subject: The Perfect Scan
Date: Mon, 30 May 2005 15:12:32 -0400
Hello Everyone,

My boss has just tasked me with completing some vulnerability scans of some
windows and UNIX based networks.   Each network contains no more then 30
nodes, (PC's)

What I'm hoping is you guys can help me find the right settings to complete
the scan.

Here are some of the characteristics I would like to see in my scan

       1)      Speed - the faster the scan is complete, the better.  Right
now it is responding slow during TCP scans.
       2)      Accuracy - the scan must be accurate and report all
vulnerabilities (less false positives)
       3)      Gentle - the scan can not crash the nodes

Here are my settings so far:

PLUGINS

       -       Enable all but dangerous (of course...)

SCAN OPTIONS

Number of hosts to scan:  30 (at the most)
Number of checks to perform...:   40 (at the most)

Optimize the test is checked
Safe checks is on  (I don't want to crash the servers...)

PREFS

TCP Scanning Technique:
- SYN Scan
- UDP Scan
- Don not radomize...

Timing Policy:
- Auto

Port Scanners
- Exclude top level domains is checked
- Nessus TCP scan
- Nmap (NASL Wrapper)

I am looking for any recommendations on how to better my scan based on the
characteristics listed above.

A few questions I have about my settings are:

Is a UDP scan required?
Should I be scanning RCP services?
My port scans are very slow.  What is the fastest way to footprint the
system?

Thanks!!
