• Complaint: Arbitrated Background Check over Markus Warg

2010-01-16
I have been asked (m20091220.2) to propose new team members for the
Software Assessment team. I talked to the suggested candidates, roughly
evaluated their qualifications and time-budgets, and came to the
conclusion that we should start the process with Alexander Prinsier and
Markus Warg.

Therefore please start the arbitrated Background Checks on Alexander
Prinsier and Markus Warg now.

Best regards,
PG

Discovery

Ruling

• The background check has not revealed any material issues in

conflict with a role under Security Policy (SP).

• During the interview, a relationship to a commercial CA was

discovered. This was observed during the interview, and discussed. The relationship has no apparent force. We therefore conclude that although a CoI exists in theory, it does not represent a material threat to CAcert.

• Investigation of potential weaknesses in social engineering

revealed that (C) had little familiarity with this topic. I recommend training in this area. A first lesson in this area was given by interviewer.

• (C) was questioned on background related to anticipated subject

matter (Software). Knowledge is based on experienced rather than on academic training.
