What is the purpose of a Limit Test?

Answer 14

Examines data and looks for reasonableness using upper and lower limits to determine if data fits the correct range. Did anyone score higher than 100%?

Question 15

What is the Test Data Method?

Answer 15

Auditor processes data with client’s computer - fake transactions are used to test program control procedures. Each control needs to only be tested once Problem with this method - fake data could combine with real data.

Question 27

What does auditing internal control in a company’s IT environment accomplish?

Answer 27

Plan the rest of audit- Shorter audit trails that may expire- Less documentation Assess the level of Control Risk - Unauthorized access to systems or data is more difficult to catch Systems access controls adds another layer to separation of duties analysis Focus should be on the general controls- new systems development- current systems changes- and program or data access control or computer ops control changes
