Clive has been hired to perform a Black-Box test by one of his clients.
How much information will Clive obtain from the client before commencing his test?

  1. IP Range, OS, and patches installed.
  2. Only the IP address range.
  3. Nothing but corporate name.
  4. All that is available from the client site.

Scanning for services is an easy job for Bob as there are so many tools available from the Internet. In order for him to check the vulnerability of company, he went through a few scanners that are currently available. Here are the scanners that he uses:
Axent’s NetRecon (http://www.axent.com)
SARA, by Advanced Research Organization (http://www-arc.com/sara) VLAD the Scanner, by Razor (http://razor.bindview.com/tools/)
However, there are many other alternative ways to make sure that the services that have been scanned will be more accurate and detailed for Bob.
