Subject: Vulnerability assessment for small business

When doing a vuln assessment for a small business (25 PC's, no server)
which is using a peer-to-peer windows network, how do you approach this?
Say the customer has a firewall...but they don't host any services.  All
of the PC's have local usernames and passwords that vary from machine to
machine.  There is no one single administrator account across the board,
and you have little time.  So you cant run many automated tools to check
patch levels and what not because you cant get remote access to the
registry.  There are no services to be tested from the outside.  Do you
manually go to each machine and test them individually?  Of course you
can run null scans on the LAN, but that is not going to provide the
depth you need.  Any ideas and pointers would be great.

I'd probably run a windows specific scan via nessus, and while that's
running use nbtenum to see how tight the machines are.

You probably want to speak with whoever contracted you to find out what
their expectations are on the deliverable.  What is their goal for
having a VA done? 

I mean a 25 PC LAN is not that hard to harden, if automatic updates are
turned on, and even just windows firewall is turned on, you probably
won't see much.  

Audit your website security with Acunetix Web Vulnerability Scanner: 

Hackers are concentrating their efforts on attacking applications on your 
website. Up to 75% of cyber attacks are launched on shopping carts, forms, 
login pages, dynamic content etc. Firewalls, SSL and locked-down servers are 
futile against web application hacking. Check your website for vulnerabilities 
to SQL injection, Cross site scripting and other web attacks before hackers do!
