How OSID is updated in Enterprise Scanner

Enterprise Scanner uses OSID information or reassesses the OSID during an assessment scan, and it explains when SiteProtector updates OSID that it has for an asset.

Conditions for reassessing OSID

The following conditions must be met for Enterprise Scanner to use the OSID information from SiteProtector:

vThe operating system name, the certainty of the OSID, and a timestamp must all be available.

vThe OSID information is user supplied, or the age of the of the information is no more than the age that is defined in the Assessment Policy.

vThe OSID matches a valid operating system.

Exception

The concept of certainty was introduced with SiteProtector SP6, so that it is undefined for the assets already in SiteProtector. Because OSID is undefined, SiteProtector accepts the first reported OSID for each asset, regardless of its source.

Rules for updating OSID

SiteProtector updates OSID for existing assets based on the following rules:

Table 24. Rules for updating OSID

Certainty of Old Data	Certainty of New Data	Updated?

Certain	Certain	Yes

Certain	Uncertain	No, unless both sources of
		OSID are Enterprise Scanner

Uncertain	Certain	Yes

Uncertain	Uncertain	Yes, unless the old OSID is
		from Enterprise Scanner and
		the new OSID is from
		Internet Scanner

About user-supplied OSIDs

SiteProtector updates user-supplied OSIDs only in the following cases:

vA local Desktop agent reports an OSID to SiteProtector for that asset.

vA scan from Enterprise Scanner with authenticated access reports an OSID for that asset.

Important: If you enter user-supplied OSIDs and do not meet either of the preceding conditions, you are responsible for maintaining any changes to the OSID.
