Defining Common Assessment Settings (Assessment Policy)
Description
Dynamically determine OS if SiteProtector information is
older than x (minutes)
The maximum age (in minutes) of usable OS information in
SiteProtector.
If the OS information for an asset is older than the time specified,
Enterprise Scanner reassesses OSID (operating system
identification) when it runs an assessment scan. (See page 171.)
Default: 120
For hosts whose identified OS is uncertain, do the following:
Run all checks (lowest performance)
If Enterprise Scanner is uncertain about the OS of the asset, it
runs all assessment checks.
Run all checks that apply to general OS (intermediate
performance)
If Enterprise Scanner is uncertain about the OS of the asset, it
runs checks for all versions of an operating system. (For example,
if Enterprise Scanner is uncertain about which version a Windows
operating system is, it runs all the checks for all versions of
Windows operating systems.)
Run only checks that apply to specific OS (best performance)
If Enterprise Scanner is uncertain about the OS of the asset, runs
only the checks that apply to the exact version of the operating
system.
Do not perform application fingerprinting
Does not try to specifically identify which applications are
communicating over which ports, and runs the checks as selected
in the Assessment policy. This option does not identify
applications communicating over non-standard ports. (Checks are
run against standard ports as defined in the Network Services
policy.)
Fingerprint applications and run checks that apply to
application protocol (e.g., http)
Identifies applications communicating over specific ports, and then
runs checks that apply to the protocol in use. This option identifies
applications communicating over non-standard ports.
Fingerprint applications and run checks that apply to specific
application (e.g., apache)
Identifies applications communicating over specific ports, and then
runs checks that apply only to the application identified. This
option identifies applications communicating over non-standard
ports.
