An information security is one of the most important positions because it has the responsibilities of most settings, configuration, management and monitoring for security.

Great example Said. The Application development team has the programming code to change any sensitive data, and maintenance team should not know programming of the application. It prevents lots of frauds within an organization.

That is true Binu, A software developer should not have access to production system because he may have any programming code to change any sensitive data in the production system. This a really good example of segregation of duties.

That is true Yu Ming. It also happened to my previous company. People type all account numbers and password and print it out and post on the wall so that they can see them easily. however, many co-workers can also see the passwords and may take them down and do fraudulent acts. I think this is sooo common for all companies. too many accounts, too…[Read more]

Agreed that one posting opens at one time. If opens for many different times, many unauthorized people may thinks this an opportunity to access to make changes. so having a one posing period at one time is really important to mitigate risk of fraud.

That is true Sean! software security is one of the many different security controls. other controls also important like physical controls, employees internal controls, etc. so Businesses should not focus on administrators as the only standard.

3. Consider the list of financial and accounting controls. Rank them. Which to you believe is the most important, the least. Why?
1) Separation of duties: it involves splitting responsibility for bookkeeping, deposits, reporting and auditing. Less chance of fraudulent acts happens if further duties are separated.
2) Access controls:…[Read more] -

Good post Daniel. IT people look like not need to know about accounting or finance knowledge, however, when we started studying SAP system, we do need to have the ability to read accounting or finance terms to finish our job(homework). it is really necessary for IT people.

Alex! That is true that on the job descriptions, it is rare to see IT people need accounting knowledge. and for CS development people, it becomes impossible to let them read accounting balance sheet during their works. However, for us, IT auditors within business school, it becomes a requirement for IT related jobs.
