week 6 - concurrent auditing Flashcards
What is concurrent auditing
Collection of evidence at the same time as an application system is undertaking the processing of data
arises from the need of identifying problems on a timely basis
Need for concurrent auditing - Explain disappearing paper trail
Concurrent auditing allows for independent data collection separate from the audit trail that is collected from the system app
Need for concurrent auditing - Explain monitoring of tightly coupled systems
Systems require continuous monitoring as issues are able to be propagated from one system to another
Need for concurrent auditing - Explain increasing difficulty of walkthroughs
Concurrent auditing facilitates understanding as information is stored in a central location.
With computer systems becoming more complex it is harder or impossible to track transactions
Need for concurrent auditing - Presence of entropy in systems
Entropy is the tendency of systems toward internal disorder or eventual failure of the system
Concurrent auditing solves this by identifying issues early and implementing preventive measures
Need for concurrent auditing - Problems posed by outsource and distributed information system
Auditor can not always be there physically for data collection especially it is outsourced to another country
Need for concurrent auditing - Problems posed by inter-organizational systems
Problems in one organization’s IS maybe propagated to another orgs IS. Concurrent audit can prevent this by solving early.
What are 4 types of concurrent techniques and explan
- Integrated test facility
- Integrate a test dummy with data into the system to test its authenticity, accuracy and completeness
- Need to decide how to integrate it, what data and how to remove the data - Snapshot
- Take a snapshot of a transaction as it flows through the system
- Embed a piece of software to system
- Decide where and when to place collection points - System control audit review file
- Embed software at strategic points to gain info about transaction or events
- Similar to snapshot but take more info and data
- More complex as it involves modification to software - Continuous intermittent solution
- Variation of SCARF and used for DBMS
- When transaction saved to DBMS it is then passed to CIS where it analyze data
