Re: PCI Compliance (Vulnerability Scans)



Correction - Level 2 and 3 merchants are also required to have
external vuln scans by an ASV. Level 4 merchants are exempt but their
acquirer can still require them to be scanned by an ASV.

If a tool is just looking for ports 22,23,25,80 and 445 for service
discovery, I highly doubt if it can pass the certification
requirement.

You are also right about the level of automation possible. Manual
verification is necessary to eleminate false positives.

First, why are you looking for a PCI compliant tool?

Second there are only 2 reasons to do vulnerability scanning. If you are
level 1 (merchant, service provider or hacked entity:) then you are
required to have external vulnerability scans by one of the authorized
scanning providers. There is no need here for software as the service
provider does all the work and provides you results.

If you are looking to do your scans internally, there is no specific
needs outlined by PCI for internal vulnerability scans. PCI only says
you need to perform vulnerability scans. With that in mind, Nessus scans
work internally :)

What are you trying to accomplish?

I am now wondering though, if you use an automated tool (VA Scanner that claims to be PCI compliant), does that mean whatever it finds and whatever it rates it (i.e. HIGH), is the final word, and the company fails? I guess what I am asking, I was under the impression that PCI scans could be much automated and very little to no user intervention was required (unlike a Vulnerability Assessment/Penetration test). However, many automated tools have false positives. Doesn't a company fail if they have any "HIGH" findings? With that said, are you required to go through each finding and validate? If so, then you have just turned it into a Vulnerability Assessment.

Upon finding any Host with these ports open, it will then run a common port scan. Is this way off? What do most of you do for host discovery (i.e. nmap scans of what ports? or different tools?
