      Exceptions Response of Digi-Sign
    (as documented in the assessment report or subsequently reported by Digi-Sign)
    i. There were 38 incidents where the time-stamps of receipt of the ID-Cert Revocation Requests were missing. In the Certification Practice Statement (version 1.9) of Digi-Sign, it states that "Digi-Sign will keep records of the time and date of receipt of a revocation request, and endeavour to process the revocation before the end of the next working day of its receipt at the Digi-Sign Office." Digi-Sign confirmed that for all the 38 incidents, action was taken to ensure the certificates involved were properly revoked and published onto the Certificate Revocation List (CRL). The staff members of Digi-Sign assigned to timestamp all incoming correspondence from customers had been reminded to exercise more care in carrying out the procedures laid down and their supervisor had also instituted closer scrutiny.
    ii. Digi-Sign did not publish its Certificate Revocation List (CRL) during non-working days for the period from 26 July 2001 to 20 November 2001, while the CPS requires Digi-Sign to update the CRL daily. Digi-Sign confirmed that it had fully complied with its obligation to publish the CRL in accordance with the CPS in this aspect since 21 November 2001.
    iii. Digi-Sign failed to conduct regular testing of its Business Continuity Plan (BCP) during the period being assessed. According to Digi-Sign's BCP, testing of the plan is to be conducted at 6-monthly intervals. Digi-Sign confirmed that all the items stated in its BCP had been fulfilled after conducting an IT production system failure rehearsal and a drill on CA key compromise in June 2002 and August 2002 respectively. Digi-Sign will conduct disaster recovery drills on a regular basis as stated in its BCP.
