Offtopic: Apache Struts vulnerability: how to detect Struts & will DB encryption help

[Sunhux G <sunhux@xxxxxxxxx>]

Understand Apache web servers (runs on Unix only) & Apache Struts
(can run in Windows & appliances) are different things:

Q1:

Can the various VA scanners (like Nessus & McAfee Vulnerability Manager)

detect the presence of Struts or you'll need to login to individual servers/

endpoints or have an agent running in them (like SCCM or MS Desktop

Central) to check for the presence of Struts?

Q2:
Will DB encryption help stop Struts vulnerabilities eg, the recent one?
Is the following true (someone told me):
  If hackers directly access the database (say using sql query tools/command
to get sensitive data) on an encrypted DB, they would be stopped;
  if they hacked a user password or exploited a website (that had vulnerable
Struts to the encrypted DB, it would be no help. 

It's kinda saying if my PC's HDD is encrypted (with a PBA password

required), hackers can't access a powered down HDD but if the PC

is powered up & logged in & there's a remote execution vulnerability

to my OS, hackers can still get data out of my encrypted HDD via

this remote execution vulnerability : is this a fair analogy?
