AUD- Information Technology Flashcards
What does auditing internal control in a company’s IT environment accomplish?
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/data access control or computer ops control changes
When is an audit of IT NOT required?
Controls are redundant to another department
The system doesn’t appear to be reliable and testing controls wouldn’t be an efficient use of time
Costs exceed benefit
When can an audit of IT be performed without directly interacting with the system?
System isn’t complex/complicated
System output is detailed
What is the role of a Database Administrator?
Responsible for IT internal control
What is the role of a Systems Analyst?
Recommends changes or upgrades
Liaison between IT and users
What is the role of the data Librarian?
Responsible for disc storage
Holds system documentation
What is the benefit of Generalized Audit Software in an audit?
Uses computer speed to quickly sort data and files, which leads to a more efficient audit
Compatible with different client IT systems
Extracts evidence from client databases
Tests data without auditor needing to spend time learning the IT system in detail
Client-tailored or commercially produced
What is a Relational Database?
Group of related spreadsheets
Retrieves information through Queries
What is a Data Definition Language?
A language that defines a database and gives information on database structure.
It maintains tables, which can be joined together.
It establishes database constraints.
What functions are performed by a Data Manipulation Language?
Maintains and queries a database
Auditor needs information, so client uses DML to get the information needed
What functions are performed by a Data Control Language?
A Data Control Language controls a database and restricts access to the database.
What are Check Digits?
A numerical character consistently added to a set of numbers.
It makes it more difficult for a fraudulent account to be set up or go undetected.
What is the purpose of a Code Review?
A Code Review tests a program’s processing logic.
Advantageous because auditor gains a greater understanding of the program.
What is the purpose of a Limit Test?
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%?
What is the Test Data Method?
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.
