This seems to be a widely spread misconception.
The actual holes are only a small part of security and thus of a security
audit, but also of the penetration test phase itself.
Just auditing the 'crunchy outside' by looking for 'every single hole you
can find' does in no way constitute a complete audit or even a
complete penetration test.
A major part of the security assesment should be an evaluation of the
provided containment and concequent risks for all systems that could
possibly contain holes that are not known at the time of the audit.
Security is not just about bugs, its 'MOSTLY' about 'CONTAINMENT' and thus
security assesments and penetration tests, and with them the time needed
to complete them should also be mainly about auditing the containment of
systems with unknown bugs/holes and not just about finding as much as
possible known and unknown bugs/holes in these systems.
