• System audit is a very effective approach to know
  the effectiveness and reliability of the system.
  Its also a very disciplined approach to know
  whether an individual element of the system is at
  par with the system and effectively working. It
  also helps to maintain data integrity and helps
  to achieve organizational goal.
• NATURE OF SYSTEM AUDIT
• We have come a long way in the line of audit use.
  We started from the financial audit, which was
  using paper-based books of account in an early
  day. Now we have moved on to a computer-based
  approach which relatively makes the process
  easier but on the other hand increase the
  complexity of system and risk of error, sabotage,
  and fraud. Now we cannot rely on only a single
  book based approach, we have to check the
  vulnerability of the system to know if there is
  any risk involved related to system exposure and
  whether data is safe.
• The nature of the system audit is not only about
  checking of the system, but it is also spread to
  the importance of it and if there is any need of
  it and what will be the possible risk of it.
