#normalize_scanner_fp(fp) ⇒ Object (protected)

Convert a host.os.fingerprint Note into a hash containing the standard os fields

Also includes a :certainty which is a float from 0 - 1.00 indicating the scanner's confidence in its fingerprint. If the particular scanner does not provide such information, defaults to 0.80.

TODO: This whole normalize scanner procedure needs to be shoved off to its own mixin. It's far too long and convoluted, has a ton of repeated code, and is a massive hassle to update with new fingerprints.

#parse_windows_os_str(str) ⇒ Object (protected)

Take a windows version string and return a hash with fields suitable for Host this object's version fields.

A few example strings that this will have to parse: sessions Windows XP (Build 2600, Service Pack 3). Windows .NET Server (Build 3790). Windows 2008 (Build 6001, Service Pack 1). retina Windows Server 2003 (X64), Service Pack 2 nessus Microsoft Windows 2000 Advanced Server (English) qualys Microsoft Windows XP Professional SP3 Windows 2003

Note that this list doesn't include nexpose or nmap, since they are both kind enough to give us the various strings in seperate pieces that we don't have to parse out manually.

#validate_fingerprint_data(fp) ⇒ Object

Determine if the fingerprint data is readable. If not, it nearly always means that there was a problem with the YAML or the Marshal'ed data, so let's log that for later investigation.
